Hello, LoL-ers ^^, so finally I am going to give some of my time to my most favorite champion - in my most favorite role - The jungle. Firstly, let's talk about the new runes, kudos to riot on that, I was actually disappointed at the amount of customisation that can be done in a game for a champion. I mean every AD carry went with the same runes and masteries buying the same items and ending up doing the same thing every game.

I like the customisability of this new system. So in this guide, I have tried essentially all the rune combinations on Master Yi. I have and will continue to add the rune pages, which are effective and fun, with explanations of the selections, item details and so forth to complete the guide.

Guide colour and abbreviations

• Physical damage and attack damage (AD)
• Magic damage and ability power (AP)
• Healing (health regen) and health (HP)
• Mana regen and mana
• True damage and other special stats - Movement speed (MS), Cooldown reduction (CDR)
• Attack speed (AS)
• Armour (Ar) and Magic resist (MR)
• Critical chance and damage
• Crowd control (CC)

Master Yi - the ignored jungler =)). With the constant changes to the jungle and items, Master Yi finds it incredibly hard to find his way into picks and successful games. This guy has everything, everything that every other champion has, except crowd control, but you don't need that. Not much to say here other than that since he isn't much suited for top lane anymore, he gets to jungle more. Yi is finding it harder and harder to find his place on the rift, due to other assassin and fighter junglers, having crowd control and stealth, becoming more viable.

Let's look at some numbers here, (taken from league of legends fandom page - Master Yi and League of legends champion info - Master Yi.)

Passive

Double strike

Sneaking in a little extra damage every 4th attack dealing an additional +50% of total AD as physical damage, applying on-hit effects as well as being able to critically strike.

Q

Alpha strike

25/60/95/130/165 +100% of total AD (+ 60% of total AD, if it is a critical strike).

W

Meditate

Healing by 120/200/280/360/440 +100% AP over 4 seconds (30/50/70/90/110 + 25% AP per second) and can be cancelled. It also provides damage reduction of 50/55/60/65/70% while being chanelled it pauses the duration of Wuju Style and Highlander. When canceled or completed, it provides a Double Strike on the next basic attack.

E

Wuju Style

Passive +10% of total AD as bonus attack damage, when not on cooldown. Active deals true damage of 18/26/34/42/50 +35% of bonus AD for 5 seconds.

R

Highlander

Increased MS by 25/35/45% and AS by 30/55/80% for 7 seconds, while being immune to slows. Kills and assists during Highlander extends the duration by 7 seconds and reduces the cooldown on his other abilities by 70%.

Yi certainly has a unique set of tools at his disposal, being harmful to both him and his opponents (more emphasis on the latter). Let's talk about his abilities.




This is Yi's prized possession. This can be used to finish off kills that are out of range for basic attacks, can be used to escape a chase or close a gap, can be used to access enemies over walls, without using Flash, and of course deal a huge amount of damage.

Alpha Strike can also be used to dodge skill shots, area of effect (AoE), Ultimates (R) and cancel abilities.






This is a really fun trick on Yi that most people forget about its existence. Time and time again you get tower dived on for that last hit to finish you off, but little did they know that Meditate would sneak up on them. Was it luck? I think not. This is Yi's life vest, so use it wisely.







Not much to say for this as it simply increases your damage output and allows you to do some true damage. One thing to remember is to activate this after using (or towards the end of the last blink) Alpha Strike. An important point to take note of is that this ability's Passive and Active are sort of in an either or relationship. If Wuju Style is available for use the passive of +10% AD is active. And after you use the ability to deal true damage, when it goes on cooldown the bonus 10% AD passive is lost for 18/17/16/15/14 seconds.




This basically let's you do everything faster, grants you target access and gap closing speeds. Usually activated once the team fight has started while trying to flank to the backline to get to the carries of the enemy team.

As mentioned in Unique Skills, Yi's Alpha Strike is important and hence is always the first to hit the max on level-ups. Wuju Style and Meditate are situational.

Most of the time you would prefer Wuju Style to be maxed out second as it increases your damage.

Meditate You can always make sure your meditate has at least 2 or 3 levels before you max out your Wuju Style. This can help you sustain in 1 v 1 fights as it increases the damage reduction, based on its level, during its use. For the 4 seconds of use you can have a damage reduction of between 55 and 60% while you heal up, gain Double Strike and maybe gain access to Wuju Style again, if timed correctly.

Highlander is a priority skill, just as in most champions, when the ultimate is available for a level-up, use it for the ultimate.

A pretty standard pick for any jungler in any format of the game on summoner's rift (possible exceptions to AURF). Smite is a very important tool which can allow you to secure objectives such as dragon, baron and the rift scuttler on a regular basis. Securing might also involve a bit of stealing them away from the enemy team. Just as with everything else for Yi the timing on smite is also very important.

Another standard pick for most champions in league of legends in any role. It indeed makes a difference in that little distance you can cover at the right amount of time, which can make or break the game. You can use flash to avoid getting focused in a team fight, escape skill shots from crowd controlling abilities, as a gap closer to get your kill safely, steal an objective such as baron or the Elder dragon.

If you want to learn your timings and successfully secure the kills during ganks or by tower diving into a low-health enemy champion, then Ignite is your tool to abuse. Perfecting your timings and escapes with Yi takes a while to master, but if you think you are ready then Flash will become kind of a secondary option to Ignite. (you can practice in normal games without Flash and avoid using it in ranked games until you are sure you don't need it and are fine with dying (tilt-proof) because things get really ugly really fast, especially for a squishy Yi.

Fleet Footwork is necessary for sustain in the jungle especially if you have picked the attack speed stat shard for bonus rune stats. It provides heal and bonus damage while clearing camps. Similarly, Ravenous Hunter also provides some sustain on clearing jungle camps and helps during ganks when using Alpha Strike and Wuju Style. Presence of Mind is more effective in late game team fights as it almost refreshes your ultimate's cooldown for it to be used again in no time. Which is very helpful in getting objectives once you have won a team fight. While, Coup de Grace and Sudden Impact allow you to deal more damage to squishier targets and well as dealing increased damage to targets with low health.

Works well with Alpha Strike as the attack speed from Skirmisher's Sabre - Bloodrazor, Blade of the Ruined King and Guinsoo's Rageblade (+50% AS, +25% AS, +25% (+40% AS at 6 stacks) AS, respectively) refresh it faster to be recast quickly. While auto-attacks also deal physical damage as well as 4% bonus physical damage based on the target's maximum health (thanks to Skirmisher's Sabre - Bloodrazor), 8% bonus physical damage based on the target's current health (thanks to Blade of the Ruined King) and at full stacks - Guinsoo's Rageblade triggers those bonus damages an additional time. While, challenging smnite also deals bonus true damage over 3 seconds (which refreshes with auto-attacks), with increased attack speed and Wuju Style this deals a ton of damage regarless of the target's armor.

Infinity Edge deals 30% of your AD as true damage everytime you critically strike an enemy champion. But since it is reliant on another critical strike chance item, Phantom Dancer is the preferred item, since it provides an additional +45% AS and 12% damage reduction from the most recently attacked enemy champion.

Hail of Blades provides an attack speed boost for the first three basic attacks, this means in early game fights you can deal more damage without having access to any attack speed items as yet. It also effectively enables you to stack Guinsoo's Rageblade stacks faster in a team fight. Sudden Impact, Eyeball Collection and Gathering Storm increases your damage by providing lethality, +6AD at 20 stacks and scaling bonus AD as the game goes on, respectively. While Ravenous Hunter provides heal on your ability damage, Transcendence increases your bonus AD based on the cooldown reduction amount. These two go hand-in-hand as you can cast Alpha Strike with basically no cooldown between each cast (due to it's passive) and of course heal as your damage enemies with it.

While Hail of Blades works well in stacking Guinsoo's Rageblade, Essence Reaver should be purchased as the first item as it provides the necessary attack speeds when using Highlander and provides sufficient damage, cooldown reductions and mana restorations. This helps you to stay in extended fights while dealing a lot of damage quickly to the first enemy target. Death's Dance provides healing on the ability damage which have short cooldowns, thanks to essence reaver, it also provides sufficient damage and cooldown reducton, in addition to providing a safety against burst damage by converting it to damage over time.

Trinity Force is favoured if you are ahead as it provides a ton of useful stats. Although in cases where the enemy team has a fed assassin who is doing a lot of burst damage, champions such as (zed and shadow assassin kayn), then Iceborn Gauntlet should be purchased as it provides some resistance, together with Death's Dance and has cooldown reduction and slows with bonus damage from spellblade.

Skirmisher's Sabre - Bloodrazor when the enemy team has at least two tanks, otherwise Skirmisher's Sabre - Warrior can be purchased as the other items provide enough attack speed to deal damage quickly. If you are planning to get Skirmisher's Sabre - Warrior, you can sell it late game and replace it with Duskblade of Draktharr or Youmuu's Ghostblade since they provide lethality together with damage, cooldown reduction and other passives.

Glacial Augment slows the target starting at 45% over 2 seconds increasing to 55% as more basic attacks are landed, while this slow is active on a target, using an active item, with a slow, will slow them further for 60% for 5 seconds more. Since Master Yi has no form of crowd control in his kit, this can be used to set up ganks so the ally laner can land skill shots and abilities onto the slowed target. Together with Approach Velocity, it can be used to close gap on enemy targets who get bonus movement speed while in combat to escape or kite. Magical Footwear and Future's Market are the better options of the remaining runes in the Inspiration path. You can also pick Time Warp Tonic instead of Approach Velocity, in cases where you know the enemy team has no advantage in movement speed when in team fights, as Time Warp Tonic increases your survivabilty in the jungle while clearing camps and allowing you to farm and then gank with more health giving you an advantage - if you are focused during a gank. Legend: Alacrity is selected for some attack speed boost as the game progresses, while Coup de Grace is used to finish off low-health enemy champions with increased damage.

These three items are the basic items for most Master Yi builds as they provide a lot of attack speed which refreshes the Alpha Strike cooldowns to be spammed on the enemy champions. It also deals bonus on-hit damages enough to delete squishies and melt tanks.

These items are viable damage options when you are ahead, but Essence Reaver is usually the most recommended from this list, while Youmuu's Ghostblade can be purchased when dealing with mobile enemy champions and Trinity Force when you are ahead and need to stick to enemy champions that try to kite you, or tanks that try to slow you down. Duskblade of Draktharr is a very handy item as it helps you clear wards and provides additional damage when you try to flank, unseen, onto the enemy back-line.

Wit's End is a good item when the enemy has a lot of magic damage dealing champions and you need attack speed, then this gives a good amount of magic resist together with Mercury's Treads. While Iceborn Gauntlet allows you to survive an all-out burst combo from a heavily fed assassin. If you can survive the initial onslaught by the enemy assassins then you are free to punish them in anyway you like.

In addition to Wuju Style, Conqueror deals a fair amount of damage as true damage and is very effective against tanks who stack armour against Master Yi. This should help you do some serious damage later in the game as you build up the damage and attack speed. Presence of Mind and Transcendence ensure that your ultimate ability, Highlander is available when needed. while Transcendence also increases your bonus damage stats together with Gathering Storm and Coup de Grace. Legend: Alacrity ensures that you have enough attack speed if you decide to focus your item builds around cooldown reductions to increase your damage provided by Transcendence. (Since most items with cooldown reductions are damage items rather than attack speed items, with a few exceptions.)

Item purchases focused on maximising cooldown reduction stats for Transcendence to work its magic. Skirmisher's Sabre - Warrior can be swapped out for Essence Reaver for an initial burst of attack speed when starting fights.

Item purchases focused on maximising cooldown reduction stats for Transcendence to work its magic. Skirmisher's Sabre - Warrior can be swapped out for any other damage item with a cooldown reduction passive.

Item purchases focused on increasing true damage to enemy champions, since Infinity Edge deals 10% of damage as true damage on critical strikes, you need to increase your critical strike chances with Statikk Shiv and Phantom Dancer, together with Conqueror, you can deal 32% of your damage as true damage, with a little help from Wuju Style and Skirmisher's Sabre - Warrior. While Guinsoo's Rageblade ensures you have a high damage rate, so you can try to fit in as many critical true damages as you can before the enemy targets can react.

Grasp of the Undying provides bonus damage and heals you based on your maximum health, while also increasing your maximum health by 5. But for this to be proc'd, you need to be in combat for 4 seconds, which is perfect since building tanky will provide you with enough sustain to do so. This synergises well with Bone Plating and Overgrowth and they increase your resistance to burst damage and increase your maximum health, respectively. Transcendence and Gathering Storm provide bonus damage as the game progresses and since most "tank" focused items have some amounts of cooldown reductions, stacking them will increase your damage while making you tanky, thanks to Transcendence. If you are playing support, and against enemy laners that can harrass through constant poke, then Bone Plating and Revitalize are better choices. Whereas in a lane against a melee-tank support, Bone Plating and Overgrowth would be the preferred choices. If you are planning to play tanky Master Yi in the jungle, then Conditioning can be picked instead of Bone Plating since there won't any enemy laners to deal with unless you are ganking, however, Bone Plating is more effective against late game burst damage or kites.

A defensive focused build with elements of damage to survive and deal damage to targets. While Trinity Force and Black Cleaver provide a pretty neat set of all-round stats, Ravenous Hydra and Death's Dance provide the necessary sustain needed to not be shattered like a glass-cannon yi. Dead Man's Plate is recommended because of the bonus movement speed, while Randuin's Omen is preferred when dealing with critical strike focus carries (most Caitlyn, Jinx, Tristana, Ashe, Jhin etc... and Yasuo). Skirmisher's Sabre - Cinderhulk if you are a jungler else you can opt out for Essence Reaver for extra damage and attack speed boost early on in team fights. (in fact you can sell [skirmisher's sabre - cinderhulk]] later on and purchase Essence Reaver instead, or just build Skirmisher's Sabre and focus on other items first).

A defensive focused build with elements of damage to survive and deal damage to targets. While Trinity Force and Black Cleaver provide a pretty neat set of all-round stats, Death's Dance provides the necessary sustain to deal with burst damage. Frozen Heart allows you to survive auto attackers by slowing down their attack speed. Spirit Visage can be purchased if the enemy team is mostly dealing magic damage, while it can be swapped with a damage item such as Essence Reaver or Randuin's Omen for more protection physical damages.

There is a slight change in the pathing since the experiences have changed.

• Level 1 > Start on the side your bottom lane duo is, for a faster clear at level 1.
• Level 2 > Go Straight to the buff on the other side, for some reason people think it is easy to steal buffs from Yi =)). P.s It actually is, if the enemy jungler knows how to deal with an Yi.
• Level 2 > Raptors on red buff side or Gromp on the blue buff side, if the rift scuttler has already been taken, else take the scuttler first at level 2... once you heal up from the scuttler crab, see if you can gank top or mid if they are pushed in, else go to gromp or raptors.
• If you are on the blue buff side then get the wolves and rift scuttler if available.
• If you are on the red buff side, then get the rift scuttler, if available, and if a lane closest to you is getting pushed in, pay it a visit and release some pressure.

At this point, you should have enough health to gank bot if you are closer to them or mid if you are on the baron side. Top laners usually want to farm, unless they are pinging for help or are being pushed in. Remember to press "Tab" frequently to see who you need to help to even out the creep counts for your team.

Try to force a gank even if there is no real chance of getting a kill. Try to push the pressure of the lane. But remember if you gank first, the enemy jungler might try to follow up. So always ward in enemy jungler exit points and stick around in the bushes after your gank in case the enemy jungler decides to follow up with a counter gank after you leave.

Anyone with a similar damage output and with crowd control is a threat to Yi. But there are several ways around them. Let's look at a few obvious rivals of Yi, on the Rift.

Jax Yi has a higher damage output than Jax on account for his damage scaling on Total AD instead of bonus AD. Jax's Counter Strike covers this gap and provides Jax with that edge in 1 v 1 situations. Counter the counter Don't fight Jax if you don't have life steal and other targetable non-champions in range for Alpha Strike. Avoid attacking Jax when Counter Strike is active as it increases the return damage. Use Alpha Strike on other targets just before Counter Strike ends (most Jax players often let it end on its own rather than reactivating it for maximum damage). Another way is to activate Meditate instantly after Counter Strike is activated, this allows you to heal for 2 seconds of Counter Strike enabling Double Strike on Yi.

Xin Xin is similar to Yi, where his damage output scales on AS, to get to the sweet third strike. At three strikes Xin deals bonus AD, heals himself and dishes out a knock-up using Three Talon Strike. Despite the lack of damage output in the early game, his heal and cc provide sustain, while his Audacious Charge makes him stick onto you if he's in a winning match-up. 3rd time's not always a charm Don't use Meditate until he has used his Three Talon Strike for knock-up. Life steal always provides an advantage in these situations for Yi. Make sure that you have Alpha Strike available for closing the gap after Xin uses Crescent Guard, which is usually an escape tool, but can be used to single out one of your team-mates, you might need to get in there and help!

Yasuo Yasuo's passive allows him to reach 100% critical chance with 2 items, whereas Yi needs 4 items. Steel Tempest also provides Yasuo with cc together with Sweeping Blade to close gaps or escape easily. Yasuo's shield will ignore your first strike on him. Your Crits are Inferior Yi out-damages Yasuo early on in the game. The first thing to do is buy Stalker's Blade - Bloodrazor instead of Skirmisher's Sabre - Bloodrazor, as Chilling Smite disables his shield allowing you to get all your damage onto him without it being blocked. Secondly, do not fight a late-game Yasuo with your minion waves around, it makes him highly mobile and dangerous, so when ganking a lane with enemy Yasuo, wait for him to clear out your minion wave. Other tips and tricks include not fighting near gromp or raptors camp as Yasuo easily used it to escape, either destroy it before engaging or save your Alpha Strike to follow if you have vision on those camps. Save Alpha Strike for dodging Steel Tempest (the whirlwind) and meditate after Steel Tempest (the whirlwind) has been used.

Rengar A natural born predator of the rift, with one drawback... his gank is most effective at level 6 due to his Thrill of the Hunt. He is able to overpower Yi in a 1v1 situation, especially around bushes. Usually ganks on lanes where your teammates are on low health and easy to kill. Rengar can easily counter your gank due to his invisibility, movement speed and debuffing crowd control with the help of Battle Roar.

Kha'zix The alien version of a predator, a fed Kha'Zix with Electrocute can easily kill you in 3 shots building lethality. Sometimes you have no chance in even reacting to this. Surprise attacks provide kha'zix, and similar assassins, with a very high advantage together with damage and movement speed.

Nocturne As dangerous as an Kha'zix, this nightmarish fiend also has his own cc Unspeakable Horror and gets a movement speed buff from his Duskbringer. Needless to say his global ultimate ability Paranoia will leave you trying to catch up to his map presence every single time.

Evelynn Dominated by AD, Evelynn sneakily brings the AP burst to the table. Fortunately for Yi, her recent update has brought down the constant threats to ganks, by making sure she now has to wait until level 6 to get off an effective gank. Nonetheless, the threats of her camouflage through Demon Shade and Allure can be a deadly combo for easy ganks onto solo lanes. Your charms won't work on me Yi can easily 1v1 an Evelynn in the early and late game unless of course she is fed, then it will take time for you to catch up. Evelynn likes to engage on targets with Allure during her camouflage. If you have been marked by it, wait for the meter to fill up and then use your Alpha Strike to escape the charm or slow on her next ability.

The Hunter becomes the hunted To survive an all in burst from the assassins, the Resolve rune tree will most likely be chosen as your secondary tree, picking Bone Plating and Conditioning to reduce the initial busrt attacks from these enemy assassin junglers. To 1v1 these champs, you might have to switch up your build path and start with Blade of the Ruined King first (after completing Skirmisher's Sabre - Bloodrazor. The problem facing such champions is dealing with the burst damage as a squishy champ. You can try also build Duskblade of Draktharr as a third item as the the item's passive will also enable vision on hidden objects/champions at regular intervals but there will be a huge tradeoff for early-game Yi between attack speed, which Yi depends on, and attack damage, which Yi eventually needs. For Evelynn, Wit's End can be really effective in the early game (rather than Duskblade of Draktharr) and also if the enemy team is mostly an AP composition.

Shaco

Shacos are usually tricky to deal with because of the early access to Deceive and Jack In The Box, both of these can easily make you disengage and create and opportunity for shaco to engage onto you easily. While all Shaco's usually run Ignite and Smite it makes him even more dangerous to 1 v 1 at early levels. Shaco players love to counter after their first camp clear as it is easy to sneak up on you with low health or mana. To deal with this clown it is recommended that you run Fleet Footwork from Precision as primary rune tree (to stay fairly healthy in the early jungling) and Resolve with Bone Plating and Revitalize as a secondary rune tree picks (to reduce the initial burst and for enhancing the heal from meditate). You can also level up Meditate at level 2 instead of Wuju Style. This allows you to buy Control Ward and 1 x Health Potion with Hunter's Machete (instead of 3 x Health Potion) to avoid being sneaked up on. Before going to your first buff (blue/red) place the control ward at the other buff, which you should go to straight after the getting the first buff. Once you have the blue and red buff, it will be difficult for Shaco to counter you in the jungle and this gives you an advantage as you can clear the rift scuttler faster.

Warwick You will, more often than not, come across an off-tank Warwick rather than a squishy damage wolfy. The more dangerous one is the off-tank build which is built for sustain so naturally, in a fight, the aim of the Warwick would be to last longer than you with the self-healing kit (thanks to Eternal Hunger Jaws of the Beast and Infinite Duress) and do some damage with Titanic Hydra and Skirmisher's Sabre - Cinderhulk. And to add to the sustain the healing is usually boosted by Spirit Visage. Taming the Wolf In early game, before Warwick picks up the Tiamat, you can easily threaten to steal his jungle camps by warding carefully. Most will rush Tiamat before the jungle item which makes it impossible to duel him 1 on 1, which is equally true in the late game, unless you are far ahead of him in the game. To put a leash on the wolfie you can dodge his Infinite Duress and avoid being suppressed. To be able to kill a Warwick successfully, you will need life steal and attack speed with damage. It is also a good idea to get magic resist as the melee range combat allows him to deal additional damage from Bami's Cinder. The end game would be to out-heal and out-damage him which is right up Yi's alley. You can also try to rush Bilgewater Cutlass to try level the early game lead.	Shyvana The dragon lady of league brings a lot of tankyness and burst damage to the table, all at the same time! It's very difficult to 1 v 1 her after she's got the lead, which is easy to achieve while you are using a squishy jungler yourself. Her ganks are also more effective and can easily counter jungle to clear your camps before you do. The usual builds are with items such as Skirmisher's Sabre - Bloodrazor and Titanic Hydra which alone make her impossible to deal with as a squishy. How to train (against) your dragon Usually rushing Blade of the Ruined King before Skirmisher's Sabre - Bloodrazor or Stalker's Blade - Bloodrazor to get sustain and damage early before you get demolished by the fire hazard! Other than that don't poke the fire and avoid her until late game. Farming and late game is one way to take the game. Otherwise, you can gank earlier than Shyvana (at level 3) to create some pressure and slow down the farming of the enemy jungler. Always remember to ward the dragon pit, as Shyvana can solo kill the drake due to the advantage from Fury of the Dragonborn. You can also engage, once you have enough damage and life steal, just after Shyvana transforms out of the dragon form.	Vi Dealing with the bish with the iron fist is very tricky due to her ability to sustain due to her passive Blast Shield and knock-up cc from her Vault Breaker. Apart from that she also has a targeted gap closing ultimate ability which also provides a knock-up. Which mean it will be difficult to use Meditate while in a fight or while escaping. Denting Blows increases Vi's attack speed and provides her with armour penetration for 4 seconds. More about Vi (because I ramble) The damage from the fists comes from the use of the armour reduction and her abilities, Relentless Force and Denting Blows, which have high AD scaling. Running with mostly the Domination rune with Electrocute to do additional damage after using Denting Blows (3stacks), and sudden impact providing more lethality to add to the armour reduction for 4 seconds and an additional second of 10 lethality increasing the damage output. The usual core items for Vi is Stalker's Blade - Warrior, Trinity Force and Dead Man's Plate. How to take a punch With 2 knock-ups at her disposal, it is a stressful task to escape or heal up while in a fight. If the Vi uses her ultimate Cease and Desist and Vault Breaker, using Meditate for damage reduction during the use of Relentless Force can negate the armor reduction and reduce the damage. Vi deals a lot of damage and her knock-up gives her the advantage in 1v1 scenarios. But you can stay alive with life steal and attack speed items. The aim in this matchup would be to deal more damage to her before she can punch you to the next world.
Udyr One jungler that you do not want to see or deal with is Udyr, because of his low cooldown on his abilities and hence the easily accessible stun from Blazing Stampede is annoying to deal with and renders your auto attacks useless making you unable to 1 v 1 this champ at any stage of the game. After the Blazing Stampede is applied, the Wilding Claw is activated - dealing a huge amount of damage from the initial activation and the consecutive autos, really gives him an advantage on a 1 v 1 against any melee champ. Udyr also has one of the highest damage scaling on his Wilding Claw starting at 120% of total AD at skill level 1 to 180% of total AD when it's maxed out. Don't poke the bear The only way to counter the Udyr is to counter jungle him early on with your mid-laner or your support to keep him behind in the game. The other option would be to ban him in champ select xd. (P.s if you know other ways to counter this pick with master yi - let me know).

Items, together with the new runes, enhance your build path due to the adaptability of the runes. So depending on the runes you can mix and match the item guidelines given in this guide for the specific build style.

Each game is and will be different from every other game you have played and will play, even if it is with the same group of people. What this means is sticking to just one build every game will not be an efficient way to optimize the current situation of the game. For instance, if you are behind for any reason (compared to the enemy jungler) and the enemy jungler is stacking lethality, you need to buy Ninja Tabi or even Dead Man's Plate to survive. Similarly, decisions on which items you need to purchase will be specific to one particular moment.

On a happier note, if you are playing Yi and the game happens to run for a long period in which you can go full damage, then it would be an ideal build for Yi to do all the damage he needs to at that point. So let's look at the items by category and which best fits Yi in which specific scenario.

Itemization Menu

• 100% CritYIcal
• Core Items
• Jungle Items
• The mind is a weapon and so are these
• Resisting the Magic
• Tanks are like butter
• Healing on the job
• Rift running
• Suiting up with Armour
• Time to chill

Why so Critical? YI deals a ton of damage and it is measured in damage per second (dps), the higher that is the more auto attacks you can force into a second. With that being said, The critical chance increases the chances of you dealing critical damage (doubling the damage from your auto attacks). With a 100% critical chance, you can deal double the damage at all times.

What makes it so special with YI? Critical chance synergies with YI, firstly because of dealing a ton of damage quickly and secondly because of the bonus damage that is provided with Alpha Strike. Having a 100% critical chance means each blink to a target deals 25/65/95/130 + 100% AD + 60% AD.

With the new Infinity Edge a 100% critical chance Yi is still a very possible option but is very inefficient, since there is no bonus 50% damage on the critical strike with auto attacks and no bonus 30% damage on alpha strike on a critical strike. If you want to build critical strike items, then Infinity Edge should be purchased as a third item, as it's passive (of doubling critical strike chance) is only utilised once another critical chance item is purchased first (example: Phantom Dancer). The good news is now we only need 3 critical strike chance items, instead of 4, to reach 100% critical strike chance.

Passive Blade of the ruined king passive 25% AS +40 AD 12% lifesteal Deals bonus damage equal to 8% of the target's current health as on-hit physical damage. Active Blade of the ruined king active Deals an additional 100 magic damage while slowing the enemy by 25% MS for 3 seconds. Blade of the Ruined King is great on champs that deal damage from auto attacks in quick successions (DPS champs). It works exceptionally well against tanky champions, together with armour penetration items such as Lord Dominik's Regards by allowing you to deal more damage at the start of a fight (as the damage is higher at the beginning of the fight and gradually decreases according to the enemy's health drop). It also passively provides an all-round stats to boost Yi's effectiveness.

Passive Bloodrazor ENCHANTMENT PASSIVE +50% AS Basic attacks deal 4% of target's maximum health as bonus physical damage on-hit. Enchantment: Bloodrazor is the goto jungle item for Master Yi since it deals damage depending on the damage per second of Yi, while dealing damage based on the target's maximum health. It synergises well with Guinsoo's Rageblade as the bonus damage is on-hit and with full stacks procs twice with the rageblade. Currently this item can be grouped with Blade of the Ruined King for more dps damage based on health while taking advantage of the full-stacked rageblade to deal it twice. It is usually more effective against tanks and bruisers (the ones that you cannot almost one-shot). Since an attack speed item will be your first buy, it makes sense to pick the 2 adaptive damage stat shards for damage in the early game.

Passive Warrior ENCHANTMENT PASSIVE +60 AD +10% CDR Enchantment: Warrior is an alternative option to Enchantment: Bloodrazor if and only if the enemy team is made of a squishy composition with maybe just one tank champion as the front line. It provides a good damage stat and allows you to build a complete lethality build to delete the enemy squishies in no time. This item can go well with the "Assassin YI" and "Transcended Yi" rune selections.

Skirmisher's Sabre Commonly bought on Master Yi due to the true damage from the item's Challenging Smite while providing a vision on them and reducing their damage by 20% for 4 seconds. A single basic attack deals between 60 - 162 true damage (based on levels) while multiple basic attacks within the 3 seconds deals 140 - 378 true damage (based on levels).

Stalker's Blade is an Occasional item on Master Yi, in situations such as while playing against Yasuo (to remove his shield Way of the Wanderer or shield from Edge of Night). The item provides a Chilling Smite which does a true damage of 28 - 166 (based on level) and also slows down the target. It can also be used to deal the last amount of damage needed to kill an enemy champ as it can be cast over a range. This item works well with Glacial Augment keystone as it increases the slow and helps with closing the gap.

Passive Guinsoo's rageblade passive +25 AP +25 AD +25% AS +6.5% - 15% (based on level) of total armor penetration +6.5% - 15% (based on level) of magic penetration Basic attacks deal 15 magic damage on-hit. Basic attacks grant +8% AS for 5 seconds, stacking up to 6 times, granting a maximum of +48% AS. For melee champions', while at half stacks (3 stacks), the next basic attack fully grants the remaining stacks (6 stacks). At 6 stacks, every second basic attack triggers all on-hit effects an additional time. Guinsoo's Rageblade provides a great set of bonus stats for Master Yi. This item is truly useful only when it is fully stacked so it will be a good purchase against a tanky composition with possibly 3 tanks and 2 carries in the enemy team composition as you can stack these fully on the tanks before you delete them. Or you need to stack the rageblade before the fight because you need to kill the squishy targets quickly as opposed to trying to stack it while attacking the squishies. There are better-recommended items which can allow you to kill the carries in a maximum of 2 to 3 basic attacks. This item also goes well with Blade of the Ruined King, Wit's End and Enchantment: Bloodrazor.

Passive Essence Reaver's passive +75 AD +20% CDR +300 Mana Basic attacks refund 1% of missing mana on-hit. After casting your ultimate, your next basic attack within 10 seconds grants +50% AS and basic attacks refund 20% of your remaining basic abilities cooldown. Essence Reaver refunds mana on-hit which goes well with Guinsoo's Rageblade at full stacks (refunding mana twice). Master Yi benifits from this item's second passive (Essence flare) as it provides +50% AS and basic attacks reduce the remaining cooldown on your non-ultimate abilities by 20% for the next 6 seconds after activating your ultimate (in this case: Highlander). This cooldown refund on basic abilities synergises well with the passive of Alpha Strike making it available over and over again in very short time spans.

Passive Trinity force passive +25 AD +40% AS +20% CDR +250 HP +5% MS +250 Mana Basic attacks (on-hit) grants +20 MS, while Killing a unit grants +60 MS, for 2 sceonds. After using an ability, the next basic attack, within 10 seconds, deals +200% base AD as bonus on-attack damage. Has a 1.5 second cooldown. Not a common item on Master Yi as it is pricey for an item that does not provide enough AD, while it does provide other useful stats, there are other dedicated items which provide a focus stat boost. You can purchase this item if you are following an on-hit/on-attack build damage for example: Skirmisher's Sabre - Bloodrazor -> Blade of the Ruined King -> Trinity Force -> Guinsoo's Rageblade. The passive spellblade works well when going into a fight just after activating Wuju Style for dealing additional damage. If you are using Transcendence from the Sorcery tree and focusing your build on CDR items, then Trinity Force is a good all-round option for the cause.

Passive Death's dance passive +80 AD +10% CDR Instantly heal for 15% of all damage dealt. Converts 30% of all received damage (magic and physical) into damage over time as true damage. The damage over time deals one-third of the converted damage every second. The passive of transferring instant burst damage as damage over time allows you to stay alive against most one-shots while in fights. The 15% heal provides sustain against champions that can burst you down and also is not limited to just basic attacks which means that Alpha Strike can also provide heal which can be boosted by Wuju Style. The damage over time can be negated by using Meditate, which has its own benefits such as increasing the healing percentage and can also be negated with the rune Overheal as it absorbs true damage or the over-heal from Bloodthirster. This item is good with the "Assassin Yi" build which focuses on dealing damage in a short time boosting the heal amounts during fights. It would also be a great idea to pair this item up with Bloodthirster for life steal with basic attacks while your abilities are on cooldown. Life steal from basic attacks provides sustain against enemy champions that can poke you down.

Passive YOumuu's ghostblade passive +55 AD +10% CDR +18 Lethality +40 MS out-of-combat. Active YOumuu's ghostblade active +20% MS for 6 seconds. (45 seconds cooldown). Youmuu's Ghostblade is a great item if you have picked Celerity as one of your runes from the Sorcery tree as the bonus movement speed is made 8% more effective. This also greatly increases Master Yi's movement speed during Highlander making him highly mobile and effectively increasing his chance to access the backline of the enemy team or aid him in successfully running away from near-death.

Passive Wit's End passive +40% AS +40 MR +42 bonus magic damage (on-hit) Steals enemy MR while increases yours by 6 MR per basic attack up to a max of 30 MR. In my opinion is a good item to get after jungling item Enchantment: Bloodrazor and boots. If you are planning on purchasing Wit's End, you can buy Berserker's Greaves instead of Mercury's Treads, unless the enemy team has a lot of CC abilities. This item is especially good if the enemy team has mage mid-laner, a tanky champion and an AP support with high damage potential. It provides the early game stats that Yi needs (attack speed) while providing magic resist against magic damage and Sunfire Aegis from tank builds.

Passive Spirit Visage passive 10% CDR +450 HP +100 % base HP regen +55 MR Increases other health regen by 30% (including lifesteal). Good item if you are in the mood to try the support or tanky Yi build. Other than that it isn't really as necessary on Master Yi because you want to save your item slots for the more "traditional" items.

Passive Abyssal Mask passive +10% CDR +350 HP +55 MR +300 Mana Restores 15% of damage taken as mana and restores health equal to 20% of the mana spent (+25 HP per spell cast or 25 HP second for toggle abilities). Nearby enemies take 15% more magic damage. Good item if you are in the mood to try the support or tanky Yi build. Other than that it isn't really as necessary on Master Yi because you want to save your item slots for the more "traditional" items. Works well with Wit's End and Sunfire Aegis and Thornmail. (Items that deal magic damage). And since Master Yi is a melee champion it is easy to get amongst the enemy and not die for a while, while doing some magic damage and essentially increasing the magic damage of your team. If the enemy AP damage dealers (mid lane carries and junglers) deal damage over time or if they deal a lot of magic damage with the same ability in quick successions (Example: Katarina's Voracity, Death Lotus or Shyvana's Burnout or Teemo's Toxic Shot, Noxious Trap), then Adaptive Helm is a much more attractive option to deal with this and reduce the damage dealt to you. A full list of examples can be found here and the decision is up to you and the enemy composition. ^^ You can also try use this item so your on-hit magic damage from items such as Wit's End and Guinsoo's Rageblade is 15% more effective.

Passive Lord Dominik's Regards Passive +40 AD +35% total armour penetration. This item is usually preferred over it's counter part - Mortal Reminder as Lord Dominik's Regards provides more damage with armour penetration. But the Mortal Reminder could be useful in rare scenarios against Dr. Mundo's healing or similar champions. But as a DPS (auto attack) champ you usually want to increase your damage as much as you can.

Passive Black Cleaver Passive +40 AD +20% CDR +400 HP Reduces the enemy's armour by 4% per second, stacking up to a maximum of 24% at 6 seconds. Basic attacks grant +20 MS for 2 seconds, while kills and assists grant +60 MS for 2 seconds. Black Cleaver is not a crucial item on Yi as it is more suited for top lane bruisers. However, if you are playing Master Yi in the top lane and are against a tank ,who would normally go for the Sunfire Aegis as the first build against you, you can build Black Cleaver after getting Ravenous Hydra or after Tiamat if the enemy already has a lead. The passive of bonus movement speed from Phage synergises well with Celerity as the bonus movement speeds are 8% more effective.

Passive Bloodthirster Passive +80 AD +20% life steal Excess life steal healing is converted into a shield that absorbs 50-350 damage (based on level). Bloodthirster has the highest life steal stat in the game and is usually a good item even after buying Blade of the Ruined King as it also provides a shield and stacks on the life steal percentage, while providing a high damage stat enabling you to last longer in extended fights.

Passive Ravenous Hydra passive +80 AD +100% base HP regen +12% life steal (Also applies to 50% of cleave splash damage). Basic attacks deals 20%-60% of your AD to units around you, the damage decreases with the distance from the center (you). Active Ravenous hydra active deals 60%-100% of your AD to units around you, the damage decreases with the distance from the center (you). Ravenous Hydra is more of a top lane option to life steal as it provides incredible wave clear due to both it's passive (cleave) and active (crescent). It is an alternative option to Bloodthirster and stacking life steal would not be efficient because it would reduce the item slots available for more attack speed items which Master Yi thrives on. If you must stack the life steal stats on Master Yi it is suggested that you consider it when the enemy team composition is mostly "protect the ADC" type i.e mostly front-line tanks as it will allow you to stay in the fights longer to get to the ADC.

Passive Berserker's Greaves passive +45 MS +35% AS Usually used on Master Yi if your team is well ahead and you can safely go in for the kills without being afraid of being shut down by the enemy ADC or APC or assassins. Other than that the following two boots are more of a wise choice to get some protection from being poked down by the enemy ranged champions or being picked out by the enemy assassins.

Passive Mercury's Treads passive +45 MS +25 MR Tenacity: 30% reduced CC durations. Great item if the enemy team has at least two AP damage dealers (usually a mid-lane mage and the support). provides tenacity which is crucially important for a squishy champion such as Yi to escape the crowd controls quicker. Can be sold in late game after full-build (with boots), once you have life steal and enough damage.

Passive Ninja tabi passive +45 MS +20 Ar Reduces incoming damages from all basic attacks by 12%, excluding on-hit damage. A suitable item if the enemy ADC is ahead and also if the jungler is an assassin or fighter who deals damage through basic attacks. This is very useful for Yi because you take a ton of poke damage while trying to close in on the enemy ADC for a kill and want to survive long enough to actually get to the ADC. It also helps increase your armour slightly protecting you from being one-shotted by assassins (mid-lane and/or jungler) in the early game. Goes well with Conditioning and Bone Plating runes as a secondary tree ( Resolve) when against assassins building full lethality.

It is mostly a safer option to buy the Ninja Tabi and go for the Wit's End to gain that magic resist in the early game or get Mercury's Treads if enemy team has a lot of CC. As the enemy ADC will not have much of a damage build up (not enough items as yet) and magic resist is always a good idea because of Thornmail, Sunfire Aegis and Enchantment: Cinderhulk and of course the mid-lane mages.

Passive Randuin's Omen passive +60 Ar +400 HP -20% Critical strike damage from basic attacks. -15% AS of the basic attacker, for 1 second. Active Randuin's Omen active Slows nearby enemy's movement speed by 55% for 2 seconds. In very rare cases it's a good item if the enemy jungler, ADC, and mid lane are champions that deal physical damage. Works best against ADCs to lower their attack speed and reduce the critical strike damage. Not a normal pick for Yi as a jungler, but a good item if you are trying the tanky Yi build or support Yi build shown. Not necessary if you are going against ADCs who are not stacking critical strike chance items (and are instead going for a lethality build), including Ezreal, on-hit Varus or on-hit Kog'Maw, or Kai'Sa.

Passive Sunfire cape passive +60 Ar +425 HP Deals 26-43 magic damage (based on level) per second to nearby enemies. Sunfire Aegis is a good item on melee champions who want to build tanky as it deals magic damage per second and works really well with magic penetration items such as Abyssal Mask and Wit's End (which is a good items on Yi as it is). This item is similar to Enchantment: Cinderhulk but has a stronger magic damage per second and provides armor. If you are going to build tanky in the jungle, then building the Enchantment: Bloodrazor and then buying Sunfire Aegis is a better approach rather than purchasing Enchantment: Cinderhulk and Sunfire Aegis as they do not stack. Although cinderhulk does provide bonus health, it won't be as effective on Yi as you are going to build a full tank build. If you are building TankYi in a lane then Sunfire Aegis is a great item to stack on more armor after Randuin's Omen, if it is needed.

Passive Dead Man's plate passive +60 Ar +425 HP +60 MS build up at 100 Momentum stacks. Basic attacks deal on-hit bonus magic damage equal to the number of momentum stacks built up. At 100 stacks, it also slows the target by 50% for 1 second. if the basic attack dealing the bonus magic damage was a critical strike, then the bonus magic damage is also dealt as a critical strike. Dead Man's Plate is a good defensive item for chasing and catching up with stragglers. It's not really a good item on the tanky yi build for just basic armor as Randuin's Omen is a better preferred item. If you are planning to stack armor and to build onto Thornmail then Dead Man's Plate can be an additional item to stack armor. Especially against a high AD composition enemy team.

Passive frozen mallet's passive +30 AD +700 HP Basic attacks apply a 40% slow for 1.5 seconds on-hit (refreshing with every hit). Not your usual master yi item, but it has its days of being picked, especially when you are far ahead of the enemy team or when you are planning to go on a tanky build, which means you have no damage or attack speed to instantly delete the enemy but the slow from the frozen mallet and Black Cleaver or Trinity Force can help you stick to the targetted enemy champion.

Passive frozen heart's passive +100 Ar +20% CDR +400 Mana Reduces nearby enemies attack speed by 15%. Definitely not a recommended item but I thought I should mention it as being part of the "frozen" group. However if you are going the tanky build and stacking armor against an AD carry who relies on auto attacks for damage, then this item is great after Randuin's Omen, as it slows down the attacker's speed.

Passive Iceborn gauntlet's passive +65 Ar +20% CDR +500 Mana After using an ability, the next basic attack deals 100% base AD on-hit as bonus physical damage. It also creates a slow zone which also deals 100% of base AD to surrounding enemies and slows them by 30% for 2 seconds (the radius of the zone is 180 (+55% of bonus armor). If you are looking for some armor, you might want to consider buying Iceborn Gauntlet over Frozen Heart as it provides the same passive that trinity force provides, but with twice as less damage. It also provides a slow to nearby enemies.

N.B: The items and the purchase orders in this guide are merely a recommendation and a preferred item of my choice, which does not have to be followed right down to the dot. But you should rather use the information of when to pick what type of item so you to make your own decisions.

This is where we are going to be discussing all of the options that riot has laid out for us in terms of the runes. What can be selected for Master Yi, why and why nots too.

Runes Menu

• Becoming a Legend
• Dominating the Jungle
• Unleash Destruction onto the Rift
• Tanking up for the Challenge
• Bringing out the Creativeness

details Press the Attack is one of the most common keystone, from the Precision tree, on most DPS junglers. It deals 40 - 180 bonus damage (based on level), while allowing your allies to deal 8% - 12% bonus damage (based on level) to the same target for 6 seconds. To "expose" the target, you need to attack the enemy champion 3 times. The stacks refresh if the target is changed. equip to YI? It is very helpful in ganks and in late game team fights as it increases the damage an enemy takes from you and your allies. Useful the enemy front line are tanky and need to be killed faster. If Precision is taken with Domination or Sorcery then this keystone can be effective for you. details Lethal Tempo another keystone from the Precision tree. It provides 40% - 110% bonus attack speed (based on level) after 1.5 seconds once you have attacked an enemy champion. It also allows the attack speed to exceed the hard limit of 2.5 attacks per second for 3 seconds extending to 6 if the same enemy is still being attacked by you. equip to yi? If the enemy composition has 3 front line pure-tanks, then it is a good item for yi as it provides you with more attack speed the longer the fight lasts. If the enemy composition is squishy then they will usually get deleted before you get to make use of the bonus attack speed fully. details Similar to Statikk Shiv, it stacks up energy (from movements and attacks). At 100 stacks it heals you for 3 - 60 (based on level) + 30% bonus AD + 30% AP and grants a +20% MS boost for 1 second. equip to yi? If you are planning to take Precision and Inspiration as your runes it provides sustain by making up for the lack of early game damage stats, by providing regular heals while clearing jungle camps. details Dealing or receiving damage generates one stack every second for the next 3 seconds. At 4 stacks, your next basic attack within 3 seconds against an enemy champion grants 6 - 35 (based on level) bonus AD for 3 seconds and converts 20% of your damage to champions to true damage for the duration. The duration is refreshed when attacking the enemy champions. equip to YI? Similar to Grasp of the Undying you need to be in combat for more than 4 seconds to generate the stacks and be able to deal the bonus AD and true damage. Which will be difficult when going against a bruiser type enemy champion as you need to stay alive long enough to deal this damage, hence will be more effective against tank top laners who cannot burst you down before you get to proc the bonus damage.

details Overheal grants a shield of 10 + 10% of max HP for 6 seconds, decaying over 2 seconds, if healing amount exceeds your max HP. Healing, self or by allies (including life steal) refreshes overheal. equip to YI? The shield is great for early game jungle clears using meditate to gain the shield. Can be effective in team fights when you have Bloodthirster to charge up the shield in addition to the shield from it. It can used effectively before ganks to mitigate some damage in early fights. Also useful if you are a little tanky as it scales with max HP (having items like trinity force wouldn't hurt for this rune) while on the base stats alone provides a shield of 200+ in late game. details Triumph restores 12% of missing HP and grants 20 gold on champion takedowns. equip to YI? Master Yi is a high risk champion and most of the time if you go in onto the back line trying to get to the carries usually after killing them you can escape due to Highlander. The restoration of health is only useful in extended fights but also only if you can get or assist with kills. So usually more effective against a fairly squishy enemy team. details Presence of Mind grants 20% of your maximum mana and refunds 10% of your ultimate's cooldown when you take down an enemy champion or level up. equip to YI? With the additional cooldown reduction focused on Highlander, is very useful to Master Yi as it has a very high cooldown even in late game. This rune would be preferred over other runes in this slot.

details Legend: Alacrity provides a bonus attack speed of 3% + 1.5% per legend stack, with a max of 10 stacks for +18% AS in total. A stack is gained for every 20 points and the points are earned by farming, getting jungle objectives (neutral monsters) and enemy takedowns. equip to YI? The recommended default for the legend slot. Useful for Master Yi to get as much attack speed as possible without having to sacrifice item slots for it early on in the game. details Legend: Tenacity provides a bonus tenacity of 5% + 2.5% per legend stack, with a max of 10 stacks for +30% tenacity in total. A stack is gained for every 20 points and the points are earned by farming, getting jungle objectives (neutral monsters) and enemy takedowns. equip to YI? If there is heavy cc in the enemy team composition, then Mercury's Treads are available for some tenacity. Buying Mercury's Treads and fully stacking this legend rune almost provides a 50% reduction on the crowd controls imposed upon you during the fights. The problem arises when there are multiple cc's stacking onto one another, so basically if you get caught once you are dead. This is why Legend: Alacrity is preferred, but there is nothing wrong with picking this rune if you are willing to lose that 18% attack speed bonus. However this rune can be favoured if you are going for a slightly tanky build ( Precision + Resolve). details Legend: Bloodline provides bonus lifesteal of 0.8% per legend stack, with a max of 10 stacks for +8% lifesteal in total. A stack is gained for every 20 points and the points are earned by farming, getting jungle objectives (neutral monsters) and enemy takedowns. equip to YI? Life steal is not really a goto build on master yi until only at the later stages of the game. Usually Legend: Alacrity is preferred.

details Coup de Grace allows you to deal 7% increased damage to champions with 40% or less of their max health. It also grants +9 bonus AD or +15 AP for 10 seconds after a champion takedown. equip to YI? The recommended rune for the combat slot. As it is very effective in late game and helps you finish off enemies faster when they have lower health. Works well in a 1 v 1 situation as well as when the enemy team is mostly squishy champs. details Cut Down allows you to deal 4% increased damage to champions with 150 maximum health more than you. If the difference is more than 2000 maximum health then 12% bonus damage is dealt instead. equip to YI? This is useful against a tanky enemy team, but is only effective in the late game where they are stacking health items. But in late game Master Yi should be able to delete tanks thanks to Wuju Style, making Coup de Grace a more preferred rune in this slot. details Last Stand allows you to deal 5% increased damage to champions with when you are below 60% of your max healt with a maximum of 11% bonus damage at 30% below your maximum health. equip to YI? This rune is effective in skirmishes with enemy champions who have an advantage over you in early game fights. It is good against champions who can deal huge amounts of burst damage in the early game, reducing your health before you can react will at least provide you with a chance to deal increased damage which can give you an edge in such fights.

details Electrocute deals 30-180 (based on level) + 40% bonus AD + 25% AP as physical damage when 3 the enemy target is attacked consecutively 3 times by basic attacks and abilities within 3 seconds. equip to YI? Usually effective on burst damage champions especially those that can proc a special passive or ability on the 3rd strike. Has a fairly large cooldown which makes it an unattractive option on Master Yi. details Predator places an active effect to boots which after channeling for 1.5 seconds, grants bonus movement speed until your next attack dealing 60 - 180 (based on level)+ 40% of bonus AD + 25% AP as bonus physical damage. equip to YI? Not of much use to Master Yi since he already has Highlander unless you want to be a "speedy gonzales" running around the rift. It does not synergise with Celerity if you are planning to make use of the two combinations. details Dark Harvest deals bonus damage to enemy champions below 50% health, increasing the number of souls collected by 1. The bonus damage dealt is given as 20-60 (based on level) + (5 damage per soul collected) + 25% of bonus AD + 15% of AP as adaptive damage. equip to YI? This keystone works well on laning champions who can poke the enemy champions well to proc and collect souls. Not as effective on Master Yi as souls cannot be collected in the jungle at the early stages of the game. details Hail of Blades Grants 75% - 125% bonus AS (based on level) for your next 3 basic attacks and allows you to exceed the 2.5 attacks per second hard limit. The attack speed boost lasts for 2 seconds and is refreshed on further basic attacks. Goes on cooldown when out of combat for 4 seconds. equip to YI? If you want to build damage based items earlier on in the game, then this keystone is perfect to get attack speed boosts while having some damage in the bag with Domination + Precision rune selection.

details Cheap Shot allows basic attacks and abilities to deal true damage of 8 - 40 (based on level) to enemy champions who are slowed or immobilised. equip to YI? Not really needed as on a 1 v 1 scenario, he cannot slow or stun the enemy champion, unless Stalker's Blade is purchased specifically for this rune. Besides yi already has Wuju Style which provides true damage over its duration, similarly by Skirmisher's Sabre smite for 5 seconds. details Taste of Blood heals you for 18 - 35 (based on level) + 20% bonus AD + 10% AP. 20 seconds cooldown. equip to YI? The cooldown between healing is fairly high and is usually more effective in a lane rather than the jungle. If you want healing then Fleet Footwork provides a more better solution in the jungle. details Sudden Impact provides 7 lethality and 6 magic penetration for the next 5 seconds after exiting a dash/ blink/ teleport/ invisibility/ camouflage. equip to YI? Synergises well with Master Yi's Alpha Strike, as it is a blink. And scales well with attack speed and continuous use of alpha strike since the cooldown is fairly low it is usually ready again around the same time that alpha strike is ready for a 2nd/3rd time. This rune is the preferred rune for the malice slot.

details Zombie Ward provides you with a ward if you destroy an enemy ward and your next damage on an enemy champion deals 30 - 90 bonus magic damage. These wards do not count towards the 3 ward limit and also if you have a ward placed in a brush where you killed an enemy ward, you gain a zombie ward trinket to place within the next 30 seconds. equip to YI? Zombie Ward sounds like a support thing so do not even consider it! Just kidding, but not really useful on yi because there is no advantage in this regarding damage or attack speed. details Ghost Poro spawns a temporary poro in the brush and provides vision until an enemy steps into it notifies the team then goes on cooldown. Only one poro per champion is allowed on the map. If your ghost poro is on the enemy half of the map, you gain bonus stats of +5 - 20 AP (based on level) or +3 - 12 AD (based on level) depending on which stat is higher at the moment. equip to YI? Same story as with Zombie Ward, not very useful on master yi. details Eyeball Collection provides additional damage based on the number of eyeballs collected maxing at 20 eyeballs granting +0.6 AD per eyeball and an additional +6 AD at 20 eyeballs, summing up to +18 bonus AD. Eyeballs are granted for champion kills/assists and ward kills. equip to YI? The only viable rune in the tracking slot and provides damage so it is recommended if the Domination tree is picked as a primary.

details Ravenous Hunter heals you for 1.5% + 2.5% per bounty hunter stack gained by each unique champion takedown. equip to YI? It allows you to heal up on using your abilities. While also healing up on basic attacks if you have purchased Blade of the Ruined King and/or Bloodthirster. details Ingenious Hunter provides an active item cooldown of 15% + 5% per bounty hunter stack gained by each unique champion takedown. equip to YI? The most common item that has an active effect is the Blade of the Ruined King therefore making this rune not so effective for selection. details Relentless Hunter provides out-of-combat movement speed of 8 + 8 per bounty hunter stack gained by each unique champion takedown. equip to YI? Only useful if you are able to get bounty hunter stacks early on in the game. At 5 stacks it provides +48 MS but only when not in combat which is not so useful in team fights. details Ultimate HunterProvides a cooldown reduction on your ultimate ability by 5% + 2% per bounty hunter stack. equip to YI? This would be the preferred rune pick for the hunter slot, if Domination is chosen as your primary rune tree, as it provides early access to a rather high-cooldown ability. It goes well with Cosmic Insight but would be inefficient as other rune choice would be more rewarding on the damage and attack speed output of Yi.

details Summon Aery to dash to a recently damaged enemy dealing 10 - 40 (based on level) + 10% AP + 15% of bonus AD as physical damage. Healing and shield an ally champion makes aery dash to them buffing them with a shield of 35 - 80 (based on level) + 25% AP + 40% of bonus AD for 2 seconds. equip to YI? Usually used on champions with ranged abilities for poke. Unless you want to be creative and catch Summon Aery up faster and send it out again and again, while losing out on other important runes, then you can use it on Master Yi. Aery shields you for more amounts than dealing damage to enemy targets due to the healing from meditate. The damage does not scale well and even with Enchantment: Warrior it does not provide a lot of follow up damage. details Arcane Comet is similar to Summon Aery but dashes down to the location the enemy champion was hit by one of your abilities which means it can be dodged. If it hits, its deals 30 -100 (based on level) + 20% AP or 35% of bonus AD as bonus adaptive damage. equip to YI? Definitely a NO on using this keystone on Yi, because it has a large cooldown and may miss it's target also including the fact that it is only effective with ranged abilities. details Phase Rush is the Sorcery version of the Fleet Footwork excluding the heal. After using 3 attacks and/or abilities on an enemy champion within 3 seconds you gain +25 - 40% (basde on level) bonus movement speed and a 75% slow resist for 3 seconds. equip to YI? This keystone is the preferred option for Master Yi when you are looking to use the Sorcery tree as your primary tree. It allows you to stick to your enemies and increases your tenacity against crowd control for 3 seconds./spoiler]

details Nullifying Orb provides you with a shield if the magic damage you took would drop your health below 30% of your maximum health. Before the damage calculation you gain a shield, to prevent your health from dropping, that absorbs magic damage equal to 40 - 120 (based on level) + 10% AP + 15% of bonus AD for 4 seconds. equip to YI? If enemy team has a lot of high damage bursting AP mages then this is a great rune to survive those damages and gain advantages in the fights. It has a similar effect to that of Hexdrinker. Not so useful on Yi as you can still just make use of Alpha Strike to dodge incoming magic damage. details Using your abilities on an enemy champion permanently increases your maximum mana by 25 to a maximum of 250 additional mana. After reaching the limit, using your abilities on enemy champions restore 1% of your missing mana every 5 seconds (with a cooldown of 15 seconds between each proc). equip to YI? Since the mana cost was reduced further at earlier levels and as Master Yi is an auto attack champion, mana is not really much of a concern and is therefore not needed. details Nimbus Cloak grants you Ghost and +100 MS for 2.5 seconds after 1.5 seconds of activating your ultimate ability. The movement speed starts decaying after 1.5 seconds. equip to YI? Boosts the gap closing abilities of Highlander and allows you to pass through units. This movement speed bonus goes well with Celerity and with Presence of Mind for refreshing/decreasing the cooldown on Highlander.

details Transcendence provides a 10% cooldown reduction at level 10. It also provides +2 AP or +1.2 AD per 1% additional cooldown exceeding the cooldown reduciton limit, usually 40%, 45% with Cosmic Insight. equip to YI? This rune can easily provide huge amounts of bonus attack damage for Master Yi by utilising the passive item bonus of CDR, while this CDR focused build does deter from the usual build for Master Yi as well as reducing the damage availability in early game since it depends on item purchases. details Celerity increases the effectiveness of all movement speed bonuses by 8%. equip to YI? Not a usefull rune on Master Yi, unless your are planning to run around the rift like a race car, Transcendence or Absolute Focus provides more damage which is useful for yi. details Absolute Focus provides you with additional attack damage if your health is above 70% of your maximum health. It provides 3 - 24 (based on level) as bonus AD or 5 - 40 (based on level) as AP. equip to YI? Not useful on Master Yi due to being a squishy champ. Not effective because having to jumping into the back line and at the risk of being focused, staying above 70% of maximum health is rarely possible in team fights, even with lifesteal items such as Bloodthirster and/or Blade of the Ruined King which are only purchased in mid-game delaying the usefulness of this rune in the early game.

details Scorch applies a burn on your next ability that damages an enemy champion dealing 10 - 30 (based on level) bonus magic damage after 1 second. equip to YI? More effective on AP mages who can poke enemy champions with abilities. Has a fairly large cooldown and is not an optimal choice for a champion relying more on auto attacks. details Waterwalking provides a +25 bonus movement speed when in the river and also provides 5 - 30 (based on level) AP or 3 - 18 (based on level) AD. equip to YI? Is mostly effective in early game where using the river passage to gank either lanes. The bonus AD is lost once the lane is entered and in late game where most team fights take place in the lane. Can be effective around baron and dragon objectives such as getting control of the rift scuttlers on their first spawn. But has a small impact overall when compared to the other rune options available. details Gathering Storm provides more damage stats as the game progresses and is based on the length of the game. A stack is gained every 10 minutes in the game and each stack grants +8 AP or +4.6 AD equip to YI? If Sorcery tree is being used then Gathering Storm is a great option on yi from the power rune slot. Since yi and the rune bonuses are both scaling types it would be the preferred choice of rune if Sorcery is picked as the primary rune path.

details Grasp of the Undying Being in combat in the last 2 seconds, a stack is generated at one stack per second. At 4 stacks, your next basic attack, within 6 seconds, against an enemy champion deals 4% of your maximum health as bonus magic damage, restores 2% of your maximum health and It also permanently grants +5 bonus health. The duration is refreshed in combat. equip to YI? If you are planning to try out the tanky Master Yi build then this keystone is the way to do it. It passively increases your maximum health when in combat. details Aftershock provides +70 - 120 (based on level) bonus armour and bonus magic resist for 2.5 seconds when you immobalise an enemy champion. After 2.5 seconds a shockwave is released that deals 10 - 120 (based on level) + 3% of your maximum health + 15% of bonus AD + 10% AP as magic damage to nearby enemy champions and monsters. equip to YI? Don't even think about it, Master Yi has no immobalising abilities and hence cannot be used at all. details Guardian places a "guarded" mark onto an ally champion close to you including ally champions you have used your abilities on. If you or your "guarded" ally takes any damage from an enemy champion or monster, you both gain a shield for 70 - 150 (based on level) + 25% of the guardian's AP + 12% of the guardian's bonus health for 2.5 seconds. It also provides both with a +20% bonus movement speed for 1.5 seconds. equip to YI? Rather a large cooldown and with yi not really being a support champion, this rune would not be effective.

details Demolish generates stacks on enemy structures within 600 units, up to 6 stacks after 3 seconds. Your next attack on a structure with 6 stacks deals 100 + 30% of your maximum health as bonus physical damage. equip to YI? Useful if you are playing Master Yi in the lane instead of the jungle. Bone Plating is a more preferred option as it allows you to tank some poke damage. details Font of Life provides allied champions, who basic attack marked enemies instantly heal for 5 + 1% of your maximum health over 2 seconds. Slowing or immobalising an enemy champion marks them for 4 seconds. equip to YI? Since Master Yi has no form of slows or immobalising abilities this rune is completely useless on him. details While shielded, gain 1 - 10 (based on level) bonus armor and magic resist. Whenever you gain a new shield, your next basic attack, within 2 seconds of the shield's expiration, against an enemy champion deals 4 - 22 (based on level) + 1.5% of bonus health + 8.5% of most recent shield amount as bonus adaptive damage. equip to YI? Works well if allies can provide shield and if you build a tanky/bruiser type build. But Demolish is the preferred rune in this slot.

details Conditioning provides +8 bonus armor and +8 bonus magic resist and increases your total armor and magic resist by +5%, after 10 minutes into the game. equip to YI? If you are playing yi as a tanky jungler then Bone Plating is a better option. Conditioning is better for laning (top lane tank build or support), since it provides defensive stats early on rather than waiting for a certain criteria to be met. details Second Wind heals you for 6 + 4% of your missing health over 10 seconds, after taking damage from an enemy champion. The duration is refreshed if attacked again. equip to YI? The healing amount is minimal but provides sustain against a pokey enemy team composition. But this rune can be overlooked as Master Yi has Meditate which provides healing. Goes well with Revitalize if you are planning to try Yi as a support as it increases healing. details After taking damage from an enemy champion, for 1.5 seconds, the next 3 spells or attacks from the same champion deals 20 - 50 (based on level) less damage. Has a cooldown of 45 seconds. equip to YI? Preferred rune as it provides resistance against poke damage from enemy champions in lane and from burst damage from assassins.

details For every 8 monsters or enemy minions that die near you, Overgrowth permanently increases your maximum health by 3. At 120 monsters or enemy minions (+ 15 max HP) gain an additional 2.5% maximum health. equip to YI? Great to gain a little bonus health if you are aiming to go tanky. If it is sustain you are looking for then Revitalize is much more useful as it boosts Meditate's healing. details Revitalize grants +5% healing and shielding power. Healing is increased by 10% when health is below 40% of your maximum health. equip to YI? Useful on support Master Yi as it provides more sustain in the laning phase by maxing out your Meditate first. details Unflinching provides +10% tenacity for each of your summoner spells on cooldown, stacking to a maximum of +20% tenacity. It also provides you with +15% slow resist and a multiplicative +15% tenacity for 10 seconds whenever you cast a summoner spell. equip to YI? The additional bonus from activating summoner spells is usually on a large cooldown for spells such as Flash, Heal, Ignite etc... It works well on Smite as it has a small cooldown. It also increases your threat during ganks reducing the effects of slows and crowd control during ganks.

details Glacial Augment allows basic attacks to slow the enemy champions for 2 seconds, which increases over the duration. The initial slow is 45% which increases to 55% over the duration. Using an active item which slows the enemy champion, while they are affected by the glacial augment slow triggers a freeze ray which creates a slowing field for 5 seconds that slows the units inside by 60%. equip to YI? By using the "Yinspiration" build Inspiration + Precision for that additional attack speed and the unorthodox style of glacial augment slows. Glacial Augment's freeze ray works well with Blade of the Ruined King's active slow. details After using an ability, Kleptomancy grants you 5 gold or a consumable item on your next two basic attacks against an enemy within 10 seconds of using an ability and cannot be activated more than once every 2 seconds. equip to YI? Not as rewarding on Master Yi due to having to get into melee range to activate it. Its not as effective while jungling because you don't have a regular interaction with enemy champions especially earlier on in the game unless you are constantly ganking. details Unsealed Spellbook lets you swap out your summoner spells, while out-of-combat for 5 seconds, to a new single use summoner spell, that you don't already have equipped. Your first swap becomes available at the 6 minute mark, with an initial 240 second cooldown. Selecting a summoner spell reduces the swap cooldown by 20 seconds, up to once per unique summoner spell. You must swap to 3 different summoner spells before returning to one you've already used. equip to YI? Not useful on Yi, mainly in the jungle, Smite is always necessary while flash, teleport and ignite can be swapped if needed, in case you would like to try this rune out with the only option being Glacial Augment.

details Hextech Flashtraption replaces Flash with hexflash when it is on cooldown. It allows you to blink to a location within the possible range after channeling for 2.5 seconds for maximum range, while it can be recast to blink before reaching maximum range and after 1 second of channeling. equip to YI? The channeling time takes too long leaving yi in a vulnerable position for attacks. It is more useful on playmakers - not a category Master Yi falls into. details Magical Footwear provides you with boots at 10 minutes, with -30 seconds per takedown. It provides an additional bonus movement speed of +10. Meanwhile you cannot purchase Boots. equip to YI? It is the preferred rune from the contraption slot if you are using Precision and Inspiration and goes well with Celerity. details Perfect Timing provides you with a Stopwatch at 10 minutes into the game while it reduces the cooldown on Guardian Angel's passive as well as Gargoyle Stoneplate and Zhonya's Hourglass's active by 15%. The stopwatch allows you to go into stasis for 2.5 seconds making you untargettable, invulnerable, without being able to attack or move for the duration. After the use, Stopwatch transforms into a broken Stopwatch. equip to YI? Not recommended on Master Yi because once you go in and get locked down there is no way of getting out as it will be easy to lock you down again once you are out of stasis. Won't be as effective as using other optimal runes to fight your way out the backline once you get in.

details Future's Market allows you to buy items without the current gold resources available for it. the debt limit is given by 150 + 5 (gold per minute). An additional 50 gold is charged after the purchase and it is only available after 2 minutes into the game. equip to YI? Great item on yi because it provides faster access to the items you need to get some stats to make you really effective in ganks. Also helps when you are falling behind in the game. Preferred rune in the tomorrow slot if you are picking the Precision and Inspiration combo. details Minion Dematerializer can be used to execute target minions and grants 4% increased damage to the same minion type dematerialized. Stacking dematerializer on the same type of minion increases the damage to it by 1% maxing to 9%. You get a maximum of 6 dematerializers. equip to YI? Not at all useful on Master Yi especially in the jungle, even then not useful with yi in the lanes. details Biscuit Delivery provides you with a biscuit at 3:00, 6:00, 9:00 and 12:00. Consuming a biscuit restores 15% of your missing health and mana over 15 seconds, as well as permanently increasing your maximum mana by 40. equip to YI? Useful in staying alive in a lane mainly as a support or midlaner. Not needed on Master Yi in any role and the preferred option is Future's Marketin this slot.

details Cosmic Insight provides a +5% cooldown reduction and increases the maximum cooldown cap of 40% to 45%. It also reduces the cooldown of summoner spells and item actives by 5%. equip to YI? Not really effective on master yi even if you are planning on taking Transcendence as the increase in CDR cap is negated by the +5% CDR gained. details Approach Velocity provides +15% bonus movement speed when moving towards a movement impaired allied champion or towards an enemy champion whose movement you impair. equip to YI? Works really well with Celerity and the Chilling Smite from Stalker's Blade as the smite slows the enemy and therefore giving you a movement speed boost and thereby providing you bonus damage for the duration. This is the preferred rune in the beyond slot from the Inspiration tree. details Time Warp Tonic grants 50% of its health o rmana restoration immediately after consuming a potion or biscuit and you gain +5% bonus movement speed while under the effect. It also puts the consumable on a short cooldown. equip to YI? Not useful on yi as Approach Velocity provides more than double the percentage movement speed boost, but is also a good rune if you plan on extending your first camp clears in the jungle and ganking whenever it's possible as this rune increases your sustain in the jungle and replenishes health faster before/during/after ganks.
