Thornmail Master Yi Build

General

1. You rush Thornmail.
2. You go full Armor.
3. Hit or miss. Works only if an enemy team is full of physical damage dealers (preferably auto-attackers).
• If an enemy team is full of mages, AP poke damage, consider playing regular tank build instead.
• However, this build also gonna work to some degree as players usually still auto attack anyway (not as good as vs full physical damage dealers / auto attackers)

Champion

1. This build is about Meditate (W). You go in, they focus you, you use W and soak tons of damage and you do tons of damage while doing that.

General

1. How is this Thornmail build for Master Yi different to regular tank builds? Item order, Armor stacking and countering enemy physical damage dealers!
2. This build is aimed to counter AD comps. Since you don't know the enemy team, you need to adapt in game. It is hit or miss. If they are heavy AP - you can just play regular tank.
3. Late game, you can consider selling boots for 6th item - for even more sweet Thornmail damage!
4. Remember to consume your Grasp of the Undying procs!

Champion

1. Invoke chaos in teamfights. Run around fights. Alpha Strike (Q) around. Run into enemy. Get focused and then use Meditate (W).
2. Watch out for enemy CC. You can wait for their CC, then use Meditate (W). Or alternatively, use Meditate (W), they will interrupt it right away and then you Alpha Strike (Q) out.
3. The more people you tag by dealing damage to them either directly or with Thornmail, the more resets during fight you get.
4. If an enemy team has tons of interrupts, just play a normal Master Yi tank version, because you are gonna get frustrated a lot.
5. There are two mandatory items for this build. Catalyst of Aeons lets you constantly use W in fights (it drains % max mana per second) and Thornmail, which lets you damage your enemies while they try to kill you.
6. You don't need boots for this build, however, if you want to boost your damage, get Sorcerer's Shoes. It will buff your Thornmail damage, Sunfire Aegis damage and Jak'Sho, The Protean damage.
7. You can sell Catalyst of Aeons late game.

Alpha Strike (Q)

1. You can use Alpha Strike (Q) to drop turret's aggro. That's very important during dives!
2. Use Alpha Strike (Q) to poke enemies standing near minions — the ability will bounce to nearby targets, letting you harass safely from a distance. Works with your Wuju Style (E) as well as with On-Hit items!
3. By using Q on a dying minion — if the minion dies mid-cast - you won't teleport. This can be useful to baiting enemies as well as dishing out some poke with Q.
4. Alpha Strike (Q) can be used to escape by targeting nearby minions or enemies — you're untargetable during the cast, which can help dodge key skill shots or buy time for cooldowns and allies.

Wuju Style (E)

1. If you are sure you are gonna hit someone with Q, you can activate Wuju Style (E) mid-flight for additional poke damage.

Riot

1. If you're in a lane against ranged players, leveling up Meditate can allow you to stay in the lane longer and gain levels faster than they will.
2. Wuju Style is very strong early for last hitting minions.
3. Try using Alpha Strike on a minion in front of an enemy champion so you are placed at a safe distance at the end of the spell.
