Heartsteel Master Yi Build

1. You play Heartsteel Master Yi.
2. You rush Heartsteel #1 and stack as much HP as possible.
3. You build items that scale and benefit from HP, then add Armor and MR depending on the enemy team.

Getting started

1. You rush Heartsteel #1 unless it is going to be hard to proc it - they are all ranged and just poke you. Then you start slow with Guardian's Horn instead.
2. Guardian's Horn is a surprisingly good item for its price. You can keep it for a very long time (or even have it as 6th item).

Item Order

1. Item Order after Heartsteel is flexible. You need to see what you need in particular game:
• Get Overlord's Bloodmail for more damage and AD.
• Get Warmog's Armor as anti-poke item (helps you stay in lane) and for some sweet HP.
• Get Unending Despair, if there are prolonged fights in which you can stay near enemies (or enemies near you). The items gets better, the more HP you get.
• Get various Armor and/or MR items to counter enemy team.
• Get Titanic Hydra for more fun, more damage and some survivability.

During fights

1. Your main damage and power comes from auto attacks - Grasp of the Undying and Heartsteel.
2. This is auto attack oriented Master Yi build, so do it! Especially if running with Titanic Hydra or Sundered Sky.
3. You can prioritize switching between champions in the fight, just to farm more Heartsteel procs.
4. Remember to consume your Heartsteel procs!

Adapting

1. You need to adapt your items to the game. Enemy team heavy on AP? Buy MR. They heavy on AD? Buy Armor. You need some damage? Well buy that.
2. Sundered Sky is very good damage item for this build (as #2-#4 depending on the game). It scales off your HP. It gives damage and pretty good sustain in fights. Remember to switch targets to maximize the effect!

Runes

1. Second Wind scales off with your HP, so it is going to be powerful sustain rune. You can use it by purposefully triggering it by letting enemies poke you a little or walking over some harmful spells.
2. Triumph is better (heal + gold), but if you want to have easier time with your mana, go Presence of Mind.
3. Remember to consume your Grasp of the Undying procs!

Alpha Strike (Q)

1. You can dodge a lot of skillshots with Alpha Strike (Q). Even global ultimates, if you time it properly. Activate it just as the ability is about to hit you.
2. You can use Alpha Strike (Q) to drop turret's aggro. That's very important during dives!
3. 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!
4. 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.
5. 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.

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.
