After 7 basic attacks, Master Yi will strike his next target twice (if the first strike doesn't kill the target). The second strike triggers on-hit effects (including Double Strike's attack counter) and can critically strike.
Alpha Strike
Range: 600
Cooldown: 18 / 16 / 14 / 12 / 10
Cost: 60 / 70 / 80 / 90 / 100 mana
Active: Master Yi blinks to a target enemy, dealing magic damage to it and up to three other enemies within a small range of the target, with a 50% chance to deal additional damage to minions and monsters. Master Yi is untargetable for Alpha Strike's duration, appearing at the initial target's location after the effect ends. If the initial target dies before Alpha Strike ends, Master Yi reappears at his original location instead.
Active: Master Yi channels for 5 seconds, gaining increased armor, health regeneration, and magic resistance while channeling. Master Yi also heals at the beginning and end (if it lasts for the full 5 seconds) of the channel.
Active: For several seconds, Master Yi gains 40% increased movement speed, increased attack speed, and immunity to movement speed slows (but remains vulnerable to other forms of crowd control). Killing a champion during Highlander will restore all of Master Yi's cooldowns, and each assist during Highlander will restore half of his base cooldowns.
