Double Strike
Double Strike.png

Innate: Master Yi's basic attacks on-hit grant a stack of Double Strike for 4 seconds, stacking up to 3 times, with the duration refreshing on subsequent attacks. At 3 stacks, Master Yi's next basic attack on-attack consumes the stacks to strike twice, the second strike dealing 50% AD physical damage.

The second strike applies on-hit and on-attack effects at full effect and is affected by Critical strike icon.png critical strike modifiers.

If Master Yi's primary target is killed before the second strike, he automatically attacks another enemy within 300 range.

The second strike can Critical strike icon.png critically strike Turret icon.png structures.

  • Since Double Strike resets the counter on-attack and the second strike applies on-hit effects, the second strike is able to add a stack for the next Double Strike activation.
  • If Double Strike's target becomes Playful.png untargetable shortly after the triggering attack, it will still occur and deal its effects as usual.

Alpha Strike
COST: 50 / 55 / 60 / 65 / 70 Mana
COOLDOWN: 18 / 17 / 16 / 15 / 14
Alpha Strike.png

Active: Master Yi Hallucinate.png vanishes and, after 0.231 seconds, marks the target enemy and then moves to mark the nearest Sight icon.png visible un-marked enemy within 600 units, recurring up to 3 times, once every 0.231 seconds.

Upon finishing marking, or if there are no longer any targetable enemies, he Flash.png reappears「 after 0.165 seconds 」「 1.087 seconds after the start of the cast with 4 bounces 」in front of his target's current location and deals physical damage to all marked enemies, increased against Monster icon.png monsters. If his target Death.png dies or gets too far away during the delay, he will reappear at the cast location instead.

Physical Damage:
25 / 60 / 95 / 130 / 165 (+ 100% AD)
Monster Damage:
100 / 160 / 220 / 280 / 340 (+ 100% AD)
Monster Bonus Damage:
75 / 100 / 125 / 150 / 175

If there are no other un-marked enemies in range, he may strike the same enemies again, dealing 25% damage instantly.

Reduced Damage:
6.25 / 15 / 23.75 / 32.5 / 41.25 (+ 25% AD)
Reduced Monster Damage:
25 / 40 / 55 / 70 / 85 (+ 25% AD)
Maximum Single-Target Damage:
43.75 / 105 / 166.25 / 227.5 / 288.75 (+ 175% AD)
Max Monster Single-Target Damage:
175 / 280 / 385 / 490 / 595 (+ 175% AD)

Alpha Strike's primary and lesser damage can Critical strike icon.png critically strike for (60% + 4.8% to 24% 4.8% to 24%) AD bonus physical damage and (15% + 1.2% to 6% 1.2% to 6%) AD bonus physical damage respectively.

Basic attacks reduce Alpha Strike's Cooldown reduction icon.png cooldown by 1 second.

  • Alpha Strike's primary damage applies after Master Yi reappears.
  • Alpha Strike's Cooldown reduction icon.png cooldown reduction applies on Turret icon.png structures but not when Master Yi is Blind icon.png blinded.
  • When Master Yi bounces from a unit it will grant Sight icon.png vision in a 600 radius around it for up-until 0.627 seconds after Alpha Strike ends, including across terrain, though not into Brushmaker.png brushes. It will always grant vision around the primary target even if he doesn't bounce off it.
  • Alpha Strike's damage is calculated the moment the mark is placed. Because of this it is possible to inflict differing amounts of damage if Master Yi changes his AD in the middle of Alpha Strike.
  • Master Yi will follow all his primary target's movements.
    • Alpha Strike can only follow up-to 2000 units; If the target teleports a very long distance, it will not be followed.
  • Master Yi can use summoner spells with the exceptions of Flash Flash, Teleport Teleport, Hexflash Hexflash, and Mark Mark / Dash Dash during Alpha Strike.
  • If the primary target is a champion Master Yi will automatically attack it once Alpha Strike ends, and thus Master Yi will not be able to buffer other abilities.*
  • Spell Shield.png Spell shield will only block a single instance of damage.
  • If Master Yi Death.png dies during Alpha Strike and he is only focusing one target, the ability will only deal the reduced damage strikes and not the final tick of damage from reappearing.
    • If he is striking multiple targets the damage will be dealt immediately when dying, and if he dies before the bounce from the last target, Alpha Strike will deal reduced damage only to all units he already bounced from.*
  • If Master Yi enters Revival icon.png resurrection during Alpha Strike and he is only focusing one target, the ability will deal the reduced damage strikes as normal and the final tick of damage after being resurrected.
    • If he is striking multiple targets, Alpha Strike will sometimes deal the reduced damage from repeated bounces and the main damage after being resurrected, and sometimes only the reduced damage, unrelated to the number of targets available.*
