Innate:Master Yi'sbasic attackson-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-hit consumes the stacks to strike twice, the second strike dealing 50% ADphysical damage.
Active:Master Yivanishes and becomes unable to act. After 0.231 seconds, he marks the target enemy and then moves to mark the nearest visible un-marked enemy within 600 units, recurring every 0.231 seconds up to 3 times. If there are no other eligible targets before then, Master Yi can mark the same enemies again.
Upon finishing marking, he reappears and becomes able to act again「 after 0.165 seconds 」「 1.087 seconds after the start of the cast with 4 bounces 」in front of the target. If the primary target dies or is too far away during the delay, he will reappear at the cast location instead.
Master Yi then detonates the marks, dealing physical damage and applying on-hit effects at 75% effectiveness. Subsequent marks on a target instantly deal 25% damage and apply on-hit effects at 18.75% effectiveness. Alpha Strike deals bonus damage to monsters per hit.
Alpha Strike's primary and lesser damage can critically strike for (17.5% + 6.125%) ADbonus physical damage and (4.375% + 1.53125%) ADbonus physical damage respectively.
Basic attacks on-hit reduceAlpha Strike's cooldown by 1 second. Each time Alpha Strike hits a target, the durations of Wuju Style and Highlander are refreshed by their current duration. Alpha Strike does not trigger its cooldown reduction nor grant a stack of Double Strike when applying on-hit effects.
Alpha Strike's primary damage applies after Master Yi reappears.
Alpha Strike's cooldown reduction applies on structures.
When Master Yi bounces from a unit it will grant vision in a 600 radius around it for up-until 0.627 seconds after Alpha Strike ends, including across terrain, though not into 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.
If the primary target becomes untargetable and there are no other nearby valid targets, Alpha Strike will end prematurely and will not deal the damage occurring after Master Yi's reappearance.
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.(bug)
On-hit damage applied by Alpha Strike will be negated by dodge and block, but not while Master Yi is blinded.
Alpha Strike's own damage will not be negated.
If Master Yidies 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.(bug)
If Master Yi enters 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.(bug)
The following table refers for interactions while Master Yi is performing Alpha Strike:
Master Yi has tempered his body and sharpened his mind, so that thought and action have become almost as one. Though he chooses to enter into violence only as a last resort, the grace and speed of his blade ensures resolution is always swift. As one of the last living practitioners of the Ionian art of Wuju, Yi has devoted his life to continuing the legacy of his people—scrutinizing potential new disciples with the Seven Lenses of Insight to identify the most worthy among them.
One of the first concepts, Yi was held by PROJECT for extensive experimentation, and then finally freed by the G/NETIC rebels. His psyche may still contain some glitches, but his experimental hyperlight “alpha” blade serves the resistance with its precision balance.
A pupil of a famous martial arts school, Yi has dedicated his life to the purity and art of combat. And yet, in his heart, he knows he is worthy of the fabled sword of jade, and a power beyond mere mortality…
A humble snowman brought to life by the magic of the Poro King, Yi strives to become the most gallant knight in all the land… and with the imminent invasion of Ice King Twitch, he might just get his chance.
The cultists of the Blood Moon have begun a dread metamorphosis, as the boundary between the demon realm and the human world is rapidly erased. Yi is among those first blessed by this new darkness, the demon within his blade arm driving him to ever greater spectacles of violence.
A legendary psychic swordsman and elite leader of the PsyOps unit. Yi is calm, professional, and always gets the job done, making him a terrifying bogeyman among rogue militaries, and a target for those harboring resentment towards the global war machine.
A powerful businessman of few words, often seen staring down on “his” strip from the comfort of his posh presidential suite. Despite his cold demeanor, Yi enjoys the finer things in life, and demands only the finest fits for his world-famous evening attire.
New Effect: If Master Yi has struck less then the maximum amount of targets and there are no eligible targets nearby, he strikes the same target for 25% damage before checking again. These minor strikes deal damage instantly.
New Effect: Duration is now always 0.8 seconds, rather than depending on the number of targets.
Now determines Master Yi's ending position when damage is dealt, rather than 0.05 seconds beforehand. In other words, Master Yi more reliably ends up next to his target if the target Flashes at the end of Alpha Strike. (Alpha Strike duration unchanged)
New: Every 4th consecutive basic attack, Master Yi will attack twice, dealing 50% damage on the second strike.
Old: 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.
Master Yi becomes untargetable and dashes to up to 4 units, dealing 25 / 60 / 95 / 130 / 165 (+1.0 total attack damage)physical damage and 75 / 100 / 125 / 150 / 175 bonus damage to minions. Alpha Strike can critically strike for 60% of Master Yi's total attack damage.
Alpha Strike's cooldown is reduced by 1 second each time Master Yi basic attacks.
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.
Master Yi channels for 4 seconds, gaining 40 / 45 / 50 / 55 / 60 damage reduction and healing for 30 / 50 / 70 / 90 / 110 (+0.3 ability power) per second.
This heal is increased by 1% for every 1% Health Master Yi is missing. The damage reduction is halved against turrets.
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: Master Yi deals 10 / 15 / 20 / 25 / 30 (+0.1 / 0.125 / 0.15 / 0.175 / 0.2 total attack damage)true damage on hit for 5 seconds. Wuju Style's passive bonus is lost while the skill is on cooldown.
Passive: when Master Yi kills a champion, the cooldowns on his basic abilities are reduced by 18 seconds (half for assists)
Active: grants Master Yi 30 / 55 / 80 attack speed and 20 / 32.5 / 45 movement speed for 10 seconds. If Master Yi scores a kill or assist while Highlander is active, Highlander's duration is extended by 4 seconds.
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.
He shared this dance with Katarina, whose dance references the other portions.
Master Yi's title in the Chinese localization also dubs him as a "Sword Sage", a title given to most master swordmen in history such as Miyamoto Musashi.
In the Chinese localization, it is instead named as "Wuji" (無極, lit. Extremeless/Apolar/Infinite). Wuji is also represented by an empty circle atop the Taijitu (太極圖 lit. Great Poles' Chart), which includes the well-known Yin and Yang. His Wuju Style ability in Chinese is also dubbed as "Wuji Jiandao" (無極劍道, lit. Extremeless Sword Path), "jiandao" is also the pinyin reading of Japanese kendou.
