Hello guys!

My name is Anabra, and I'm bringing you my first guide. I'm not a pro player, not even a high-elo player, however I've just had an idea after the patch 3.10a... Triforce Vayne. In this guide I'll compare the Trinity Force Vayne to the old Blade of the Ruined King based one. In the first few chapters I'll give you some information on Vayne, then I'll continue with the Triforce build. Enjoy it!

Pros + High burst damage + Great dueling potential + Excessively high kiting potential + Hard to focus in team fights + Late game hyper carry + Easier to farm + Has more HP early + Has higher mobility

Cons - Still squishy - Lower sustained DPS - Vulnerable to oracle - Short Range - Can get caught easily if CC locked - Has no early game life steal - More expensive - Needs high CS

• Greater Quintessence of Life Steal: This will help you out with the early phases since you have no life steal from Blade of the Ruined King.
• Greater Quintessence of Attack Damage: You will need this little AD boost in the early phases.
• Greater Mark of Attack Damage: You should buy these for even more attack damage. They will help you with last hitting and trading.
• Greater Seal of Armor: The armor yellows will help you out against aggressive ADCs such as Caitlyn or Draven. Since your Tumble is based on auto attack which means, that you'll aggro the minions and will receive some damage from them when you are harassing your lane opponent. That bonus armor will block a handful of that damage.
• Greater Glyph of Magic Resist: These runes are especially good against support with high magic damage based poke such as Sona or even Nami. You could ask why not to buy scaling MR blues. Well, I prefer flat MR runes since those support mentioned above will only have high damage in the early phases. After your first back you'll have enough HP to sustain the damage and with that little MR boost will help you out greatly.

• Tumble
  Tumble is a great skill for both aggressive and defensive plays as well. On the early levels it's not a big deal but as the game progresses it will get better and better. It will give you a really high sunstained damage in team fights. You should use this ability to chase opponents. After auto attacking your target you should immediately use your Tumble, land the attack then auto attack again. With this combo you can deal some nice damage to your opponent in the laning phase
• Silver Bolts
  This ability makes Vayne a hyper-carry. You'll deal true damage based on your opponent's max health, which means they cannot stack HP nor armor. Silver Bolts with the combo mentioned above can deal excessively high damage in both the laning phase and the team fights as well.
• Condemn
  Condemn will you help you locking down your opponent's and dealing tremendous damage to them. You should always get into position with your Tumble and then knock your opponents into some terrain. However you don't always need to pin your target to the wall. In cases like this just knock them back and land some autos if possible.
• Final Hour
  Your ultimate is one of the best amongst the ADCs. Final Hour will make your really hard to focus in team fights and will give you an amazing dueling potential. Furthermore the AD boost is considerable as well.

With the Trinity Force build you should max your Tumble first, your Condemn next and Silver Bolts last. (Max Final Hour whenever you can of course) This skill order will give a really high burst damage due to your Condemn.

We are finally here! In this section I'll explain why Trinity Force is a great item on Vayne since the patch 3.10a.

• : This is essential for all ADCs. It will give you the mobility you need in the early levels, and that little attack speed boost is not bad either.
  
• : This is such a great item on Vayne. Since the 3.10 and 3.10a patches Blade of the Ruined King has been nerfed so much. The slow/speed boost duration has been reduced to 3 from 4 seconds. It's range has been reduced from 550 to 450 and the cooldown went up to 90 from 60 seconds. However Trinity Force's cost has gone down, and it's passive has been reworked. Now it only costs 200 gold more than Blade of the Ruined King. It gives you extreme kiting potential, some tankiness, attack speed, critical strike rating AND an awesome damage boost on your autos after using a spell. You can consider it as a 100% crit after a skill.
  
• : BT is a must since you need a lot damage and life steal too. Unfortunately you'll have no life steal from Trinity Force, however you'll really need it in team fights. So you must grab this item right after Trinity Force.
  
• : You need LW when the opponent is building armor. Their armor value will become considerable by mid game. Most of the armor based such as Randuin's Omen cost more than Last Whisper. So you can easily counter-buy them.
  
• : You grab this item as your fourth major item. Guardian Angel is a great counter item against most assassins. Because most of them are cooldown based champions. (For Example: Zed or Rengar) If your team cannot protect you from the opponent's assassin's first assault, you an your team will still have a second chance. And with Vayne's Final Hour + Tumble combo it's easy to get out.
  
• : IE is a great late game item, because it gives you a bunch of ad and crit chance, plus it improves your crit damage as well. Grab this or Phantom Dancer if you need attack speed over pure damage.
  

With this item build and skill order you'll have excessive burst damage with your Condemn - Tumble - auto attack combo. Furthermore you'll have nice sustained dps as well due to your Trinity Force + Tumble combination.

I like to start with this setup. I'll explain you why. The Boots will give you some early game mobility which can help you dodging skill shots. The Health Potions will give you some sustain in the early phases. You may choose this setup if you want to rush Trinity Force very quickly.

These items will add some extra damage to your kit and you will still have the extra sustain from the Health Potions. You may choose this setup if you want to build an early Vampiric Scepter before Trinity Force.

The doran's start will give you a considerable early game boost. The more Doran's Blades you have, the more early potential they give. They will boost your damage, your sustain and your "tankiness" too. You may choose this setup if you want to stack 2 or 3 Doran's Blades before building Trinity Force.

In the first few minutes you should play passively. Freeze your lane, let the opponent push and farm as much as possible. The Boots 4x Health Potion start will come handy, because you can dodge skill shots, evade ganks and will have good sustain. When you have 1250 - 1350 gold rush back to base and grab your Phage.

The biggest problem with Trinity Force Vayne is that she has no early game lifesteal, which is a pretty big deal. However on your second back you can obtain a Vampiric Scepter and upgrade your Boots to Berserker's Greaves as well.

At this point you should have a kill and the same/higher CS than the opponent ADC. When you have enough gold to go back, buy a Zeal for some extra mobility, attack speed and crit chance. Farming will be even easier.

On your third back you should buy your Trinity Force, go aggressive and push a turret. After that, start roaming, taking buffs and securing objectives. Just push your advantage.

After this, the laning phase will be pretty much over.

Lulu

She is my personal favourite. She can protect you from the opponent ADCs poke with her Help, Pix!, easily disable him/her with Whimsy, slow your chasers/escapers with Glitterlance and her ult, Wild Growth can be extremely useful in laning phase and team fights as well. My personal favourite piece of her kit is Help, Pix! on enemy cast. It will reveal the enemy, so you don't have to spend an extra ward on the lane bushes to land your Condemn without losing sight of the opponent.

Sona is a great support. She goes well with nearly each ADC. She has excessive early game poke damage due to her Hymn of Valor and her Power Chord. She can protect you from both magic damage based poke and attack damage poke as well with her Aria of Perseverance. (Not to mention the healing effect.) The bonus movement speed from her Song of Celerity can come handy too, and the burst speed is really useful for engages/disengages combined with Shurelya's Battlesong. Her ult, Crescendo, is an extremely useful ultimate. It is such a great initiation tool and a carry-protect tool as well.

Sona

Nami

Nami is a great support in many ways. She needs game experience and ability-landing skills, but when you master her, she can become a really good support for many carries. Her passive Surging Tides will always help you in engages/disengages on lane. She also has an area stun, Aqua Prison, which is quite easy to land from unwarded bushes. Her Ebb and Flow will give you some extra sustain and some harassing ability as well. Tidecaller's Blessing is a great tool which works fine with Vayne, since your combo involves 2-3 autos. These autos will slow your opponents and deal some extra damage too, plus you'll get extra movement speed from her passive. Finally her ultimate. If Nami can land her ult well, both on lane and in team fights as well, it can be devastating. It has a really long range and it brings a heavy CC tool to your team's kit.

I'll update this guide quite frequently in the upcoming days, so don't hesitate to leave comments and suggestions!
