Trundle is a Tank, Anti-Tank he is also AD focused but with Anti-AD Abilties.. I don't know why more people play Trundle..

P - King's Tribute - Whenever an enemy dies around Trundle heal for a % of their max hp

Q - Chomp - Deals bonus damage slows for 0.5 seconds, Trundle gains bonus AD and Reduces the bitten targets AD.

W - Frozen Domain - HUGE BUFFS, Attack Speed, Movement Speed, Spirit Visage for free.

E - Pillar of Ice - Like a circle anivia wall but with a huge slow, but it also knocks back people (Allies aswell) when the pillar is summoned ontop of them.

R - Subjugate - You steal 20% - 35% of the targets max hp, also you steal 40% of their magic resist and armour.

So all in all you get buffs they get debuffs..

Trundle drains the life force out of an enemy champion, instantly dealing 10/13.75/17.5% (+ 1% per 100 AP) of the target's max health in magic damage, healing for the damage done, he also steals 20% of their armour and magic resist, he then applies the same effect to the target over the next 4 seconds (2.5/3.4/4.4% of the target's max health per second) (+0.3%per 100 AP). After the drain completes, the modifiers slowly decay (For Trundle and the Target).

Pros

Great Dueling
Great Early Game
Counters Juggernauts

Cons

Kited Easily
Very Location Based
No 'Sustainable' Ranged Damage

Maxing Chomp because this is your harass and early game damage ability, Maxing W second is just because E doesn't give much offensive potential other than stopping them from running away (I emphasise RUNNING) also because you shred towers with Q & W (You steal and deal the bonus damage to turrets).

Corrupting Potion This is great, a better flask but with damage!

Blade of the Ruined King - Great Item, Especially on Trundle slow and MORE Life Steal

Offensive Items

Black Cleaver - One of the safest items to get on Trundle apart from BotRK, gives you bonus health, MORE chasing potential and armour pen.

Titanic Hydra - Really good, deals damage based your HP goes really well with your R

Trinity Force - Now its underrated because of all new juggernaut items, it goes well because of the Sheen Proc, every Q.

Defensive Items

Frozen Mallet - Alot of Health, bit of AD but the main point is the on hit slow

Warmog's Armor - **** TON of Health, +200% Base HP Regen, this is insane for when you are in battle because 300% base regen + the Frozen Domain increase is 360% regen, plus the 3% Max HP for when you are out of battle.

Randuin's Omen - Active Slow, Attack Speed Slow, More Armour this is a basic tankyness item.

Boot Choices

Ninja Tabi - For when the enemy team is mainly AD or has a HUGE AD ***** (Such as Draven)

Mercury Treads - For when the enemy team is mainly AP or has a Le Blanc or Annie

Ionain Boots of Lucidity - This is for when the enemy is mixed, having the extra CD helps with staying in the fight and not dying, remember this is when the enemy team doesn't know what the **** they are doing.

Blood Thirster

This is a really good item on Trundle for a few reasons:
Life Steal + Frozen Doman
AD

But it doesn't give HP or anything other than these stats so it isnt good for Standard Trundle

Thornmail

Having Trouble with a Draven. This is the item, No for real if an enemy deicide to go full AD and the main form of damage is hitting you go this ( Aatrox, Draven)

Trundle in a team fight can either royally **** your own team over or do it to the other, Your ultimate can be used in two different ways:

First - Focus AD Carry

Use this on their AD carry and your team and take away the threat very fast.

Second - Trundle Rushing

Trundle Rushing is just what I like to call, Ulting their tank and using Frozen Domain and Chomping the AD carry, this is the unsafe (or Balls Deep) option in a fight this could **** your team by losing the top laner fast, or your team can go in with you with the enemy team focusing you because of your high damage and tankyness due to ulting the enemy tank.

Okay so Trundle's Attributes are a main part of this but think about it.

Trundle is an AD-Offtank (A Wanabe-Juggernaut), with Anti-AD and Tank Abilities, This is insane this is like a Darius's worst nightmare, so if you are wondering how to beat certain juggernauts, read Trolling the Juggernauts chapter.

Darius

Okay so this is probably (from a new player's perspective) the hardest and most OP Juggernaut, this is true he is the most OP Juggernaut but he is VERY easy to counter play ill go over his abilities and how to counter each one.

But trust me I mained and still second-main Darius, so I have alot of experience with him.

Haemorrhage - Just keep on fighting him, early on this is reduced by Chomp so give zero ***** about it.

Decimate - This is a easy one, just keep on running at him if he tried to W then back up use your E to either get yourself out of range or to get him in range for the inner circle to hit (because this deals 50% of the damage and doesn't heal or add a stack of haemorrhage), so just keep on fighting him using Frozen Domain will help you not get caught with the outer edge.

Crippling Strike - This is kinda unavoidable, but with Chomp this deals little to nothing more than a normal auto attack.

Apprehend - This does nothing but allow you too hit more or screw up darius so that he cannot pull you out of your frozen domain.

Noxian Guillotine - Use your ultimate when he is mid jump, or you think he is about to jump the extra HP boost will save you and you will beable to just out sustain him and kill him!



Garen

Garen isn't all that good, you counter him in pretty much all of his abilities.

Decisive Strike - Counters your slows, but deals scales off AD.

Courage - This isn't all that good, you have no burst more sustain damage so the active wouldn't be all that active if you were someone like Darius, the passive portion of it is counter by Subjugate and if you are like me and aggressive he should have little stacks any way.

Judgment - The main damage dealer, this is what makes Garen so good at sticking to his targets, Q into E is a great combo if the enemy is slow or better at 'placement' combat, Trundle has a better 'placement' combat ability Frozen Domain if W is off cooldown the all mighty ****-blocker the ice ***** of the gods (E).

Demacian Justice - This is the one part that Trundle cant counter, the passive portion is the worst, even though garen doesnt typically build attack speed his E deals the damage even though you counter that, the ult deals WAYYYY more damage by dealing true damage your ult doesnt steal enough to turn a fight around if you use it before the 'dunk' can kill you.

Illaoi

**** this champ, but with these few tips hopefully you can survive the laning stage.

Prophet of an Elder God - Eh, Tentacles heal you when they die (I think atleast I got healed).

Tentacle Smash - Move left or right not back it always hit you if you run backwards!

Harsh Lesson - Okay she will use this when you are close to her tentacles, just focus the tentacles if you are fighting one.

Test of Spirit - Try to dodge or bait this out as much as you can, if you are low just run away keep on running until you are a vessels, or if her tentacles are close just run away, When your 'Vesseled' just wait for the Tentacles to spawn then asoon has it hits kill it it cant hit more than once without Harsh Lesson being used.

Leap of Faith - This is easy, run just run away it isnt hard to run she hasnt got any CC apart from the spirit which she will use when you are running, just kill the tentacles when you are vesseled.
