The first attack functions as the trigger of Double Strike's on-hit effect and resets Double Strike's counter. The second attack will generate a stack of Double Strike if completed. As such, continuous attacking will net an activation of Double Strike on every 3rd attack.
If the target dies to the first hit, Double Strike's counter is still reset.
Cooldown: 18 / 17 / 16 / 15 / 14
Cost: 70 / 80 / 90 / 100 / 110 mana
Active Master Yi becomes untargetable and leaps to strike up to 4 enemies, dealing physical damage to each and dealing additional damage to minions and monsters.
Each bounce will target the nearest enemy that has not yet been damaged. Master Yi re-appears at the initial target's location after the effect ends.
Alpha Strike can critically strike, dealing additional physical damage equal to 60% AD. Basic attacks lower the cooldown of Alpha Strike by 1 second.
If the primary target dies or becomes invulnerable as Master Yi finishes Alpha Strike, he will appear at the cast location.
Alpha Strike counts as movement for the purpose of Statikk Shiv
Alpha Strike's critical damage component is effectively 0.6× the bonus damage a critical strike would grant to a basic attack. This cuts the normal +100% down to +60%; with Infinity Edge, it would instead cut +150% down to +90%; with Lethality as well, it cuts +160% down to +96%.
The total bonus damage is showed in the ability.
Alpha Strike cooldown reduction counts up when attacking Turrets, but not when under the effect of Blind.
The damage is calculated after Master Yi becomes targetable, meaning that bonus AD from auras will be factored. This means he can also take tower aggro from the damage dealt.
Neutral minions will reset to their idle positions when Master Yi is untargetable, but they do not reset their health.
Sword of the Divine does not count critical strikes sourced from abilities toward its 3-crit limit, meaning Alpha Strike will critically strike against up to 4 units and still have 100% critical strike chance for a second-or-so thereafter.
Alpha Strike can be used to dodge and avoid skillshots and area of effect abilities. Some dodgeable spells involve the damage instance of Time Bomb, Absolute Zero and Requiem. Being untargetable extends to allies and will dodge e.g. Wish. Since V3.13, Alpha Strike can be used to dodge targeted abilities.
Alpha Strike does not hit enemies in stealth or in the Fog of War.
If Alpha Strike is used by Master Yi, even with 0% critical strike chance, it will activate Frenzy.
Cost: 50 mana
Active: Master Yi channels for up to 4 seconds, restoring health each second. This healing is increased by 1% for every 1% of his missing health.
While channeling, Master Yi reduces incoming damage. This damage reduction is halved against turrets.
Base healing per second: 30 / 50 / 70 / 90 / 110 (+ 30% AP)
Maximum healing per second: 60 / 100 / 140 / 180 / 220 (+ 60% AP)
Base total heal: 120 / 200 / 280 / 360 / 440 (+ 120% AP)
The passive bonus is only lost after the active bonus has expired, meaning the bonus attack damage from the passive will increase the true damage dealt by the active, effectively giving it a +11 / 13.75 / 16.5 / 19.25 / 22% AD Ratio.
Cost: 100 mana
Passive: Champion kills and assists reduce the remaining cooldown of Master Yi's other abilities by 70%.
Active: For 10 seconds, Master Yi gains increased movement speed and attack speed, and becomes immune to slows. While active, champion kills and assists extend the duration of Highlander by 4 seconds.
Movement Speed: 25 / 35 / 45%
Attack Speed: 30 / 55 / 80%
Highlander is a self-targeted buff. It also passively reduces the remaining cooldowns of Master Yi's basic abilities whenever he scores a kill or assist.
Highlander is one of few abilities granting a multiplicative movement speed bonus; it stacks multiplicatively rather than additively with other movement speed bonuses.
Highlander does not resist the slows of Whimsy and Charm.
Highlander will not prevent the application of the Sejuani's "Frost" debuff, as it does not slow prior to being detonated by Permafrost.
