Resolve:Yasuo generates 1% of his maximum Flow for every 59 / 52 / 46units he travels by any means, requiring a total of 5900 / 5200 / 4600 units travelled to obtain maximum Flow. At maximum Flow, the next instance of champion or monster damage against Yasuo consumes all of his Flow and shields him for 100 - 510 (based on level) damage for up to 1 second.
The damage reduction applies to the total damage dealt (before damage mitigation). A standard critical strike is 200% damage is reduced to 180%, and a critical strike with Infinity Edge deals 225% damage instead of 250%. The reduction is not a subtraction to his critical damage statistic.
Hitting an enemy grants Gathering Storm for 10 seconds. At 2 stacks, Yasuo's next Steel Tempest is empowered and will consume all stacks.
Empowered:Steel Tempest unleashes a whirlwind that travels an extended distance, dealing the same damage and knocking airborne all enemies hit.
Yasuo can cast Steel Tempest during Sweeping Blade to change the area of effect to a circle around him, which does not benefit from Empowered's extended range. The cooldown and cast time of Steel Tempest is reduced by 「 1% for every 1.6725% bonus attack speed 」「 ~0.6% for every 1% bonus attack speed 」, down to a maximum 66% reduction.
The cooldown of Steel Tempest is unaffected by cooldown reduction.
Yasuo's 2.5% base attack speed from growth is factored into Steel Tempest's cooldown reduction and cast time reduction. At level 18, Yasuo has a total of 42.5% bonus attack speed from leveling alone which reduces Steel Tempest's cooldown by 25.4% (and he requires only 69% attack speed from items, runes and masteries to reach the cap).
Way of the Wanderer'scritical strike damage penalty with Steel Tempest is 25% instead of 10%, and applies only to the AD portion of the damage. With the 100% base critical damage, the bonus damage equates to simply 50% AD (200% × 0.75); with 150% critical damage (Base + Infinity Edge), the bonus damage equates to 87.5% AD (250% × 0.75).
Tested by Emptylord. With only critical chance runes and no masteries, Steel Tempest deals 73 damage as standard (20+53) and "99!" on critical strikes. That equates to 26 bonus damage, which is ~49% of Yasuo's attack damage. Swapping out the critical strike chance runes for critical damage runes increases the damage as detailed.
The third cast will still knock enemies airborne when it strikes as a point-blank area of effect.
Casting Steel Tempest will also "interrupt" Yasuo's attack timer but will not reset it, as Yasuo will auto-attack right afterwards when the spell ends if possible; note that this only applies to the standalone cast, as it possesses a bit of recovery time when casting it from Sweeping Blade.
COOLDOWN: 26 / 24 / 22 / 20 / 18
Active:Yasuo creates a gust of wind that travels forward to form a wall in front of him. The wall slowly drifts forward 50 units over 3.75 seconds, blocking all enemy projectiles with the exception of turret attacks.
The gust of wind takes ~0.25 seconds to travel forward from Yasuo to form the wall, but will still block projectiles as with the fully formed wall during that time (for a total of 4 seconds as listed in the in-game tooltip).
The wall grants sight over a small area.
A projectile is any entity with a velocity that is not classified as a unit (champions, minions, monsters, etc).
Moving units are not blocked under any circumstance, including dash abilities. Champion-summoned units, such as Orianna'sCommand: Attack and Maokai'sSapling Toss, are not considered to be units until they hit the ground - and thus will interact with Wind Wall while en route.
Sweeping Blade will generate ~7% of Yasuo's maximum flow innately as Flow-generation is based on distance traveled.
Yasuo can pass through terrain both before and after he's hit his target - permitting sufficient space for him to make the jump.
Uniquely, all forms of movement-inhibiting crowd control (airborne, snares, stuns, suppression, etc.) will interrupt Sweeping Blade when they hit him - rather than waiting for him to complete the dash. This is contrary to all other dashes, which are only interrupted by airborne-type crowd control effects.
The cooldown of Sweeping Blade is unaffected by cooldown reduction.
COOLDOWN: 80 / 55 / 30
Active:Yasuoblinks to the nearest visible airborne enemy champion to the cursor, instantly generating maximum Flow. Upon arriving, he suspends all nearby airborne enemies for 1 second and deals them physical damage.
For the next 15 seconds, Yasuo'scritical strikes ignores 50% of his targets' bonus armor. Casting Last Breath clears all stacks of Gathering Storm.
Last Breath is an auto-targeted ability that can only be activated if there is an airborne enemy champion nearby. The cursor's current position will influence the ability's auto-targeting, although it is not technically using quick cast and having your cursor near a valid target is not required to activate the ability.
Each rank in Last Breath extends the range of Yasuo's strikes.
Last Breath will attempt to position Yasuo outside the range of a nearby enemy turret if he initiates the ability on an enemy standing close to one. This does not, however, apply to the Nexus Obelisk.
Last Breath's damage will NOT benefit from its own bonus penetration.
Bonus armor refers to all sources of armor beyond the target's base armor and armor per level. Bonus armor refers specifically to armor granted through: runes, masteries, items, auras/buffs and champion abilities.
The bonus armor penetration applies before flat armor penetration.
Using Maw of Malmortius as an example: "Subtract 50% of the enemy's bonus armor, then subtract flat 10 of the enemy's total remaining armor".
When Last Breath is used, the duration of the target being airborne becomes 1 second, regardless of the existing airborne duration caused by a prior displacement ability, as well as any additional airborne duration created by a displacement ability during Last Breath's animation.
For example, if Yasuo uses Last Breath on targets knocked up by Malphite'sUnstoppable Force instantly the moment they were knocked up, then those targets' duration of being airborne becomes 1 second, not 1.5 seconds as a result of Malphite'sUnstoppable Force. If Yasuo uses Last Breath on targets knocked up by Malphite'sUnstoppable Force the moment they are about to land, then the duration of the targets being airborne totals to 2.5 seconds.
Therefore, to maximize the duration of a target being airborne, Last Breath is best used right when the target is about to land from a prior displacement ability.
Targets suspended by Last Breath cannot be displaced any further until the ability is completed.
Champions affected by knockback are also valid targets for Last Breath.
Note that "Airborne" is a classification of enemy-enforced crowd control and not a visual description. Only airborne-type crowd control sourced from an enemy champion will count for the purposes of Last Breath.
Jumps, including abilities recognized as self-CC, do not classify the unit as being Airborne.
Bouncing animations, such as Zac during Let's Bounce!, do not classify the unit as being Airborne (though the enemy targets he hits with it are knocked Airborne and will function with Last Breath).
