  • Previous Bio
An Ionian of deep resolve, Yasuo is an agile swordsman, trained to wield the air itself against his enemies. As a young man, pride led him down a path of loss, costing him his position, his mentor, and ultimately his own brother. Disgraced by false accusations and now hunted as little more than a criminal, Yasuo wanders his homeland seeking redemption for his past, with only the wind to guide his blade.

As a child, Yasuo often believed what the others in his village said of him: on the best days, his very existence was an error in judgement; on the worst, he was a mistake that could never be undone.

Like most pain, there was some truth to it. His mother was a widow already raising a young son, when the man who would be Yasuo’s father blew into her life like an autumn wind. And, just like that lonely season, he was gone again before the blanket of Ionian winter settled over the small family.

Even though Yasuo’s older half-brother, Yone, was everything Yasuo was not—respectful, cautious, conscientious—the two were inseparable. When other children teased Yasuo, Yone was there to defend him. But what Yasuo lacked in patience, he made up for in determination. When Yone began his apprenticeship at the village’s renowned sword school, a young Yasuo followed, waiting outside in monsoon rain, until the teachers relented and opened the gates.

Much to the annoyance of his new peers, Yasuo showed natural talent, and became the only student in several generations to catch the attention of Elder Souma, last master of the legendary wind technique. The old man saw Yasuo’s potential, but like trying to bridle a whirlwind, this pupil was known to ignore most teaching. Yone pleaded with his brother to set aside his arrogance, gifting him a maple seed, the school’s highest lesson in humility. The next morning, Yasuo accepted the position as Souma’s apprentice, and personal bodyguard.

When word of the Noxian invasion reached the school, some were inspired by the great stand that had been taken at the Placidium of Navori, and soon the village was bled of the able bodied. Yasuo longed to add his sword to the cause, but even as his classmates and brother left to fight, he was ordered to remain and protect the elders.

The invasion became a war. Finally, one rain-slicked night, the drums of a Noxian march could be heard in the next valley over. Yasuo abandoned his post, foolishly believing he could turn the tide.

But he found no battle—only a raw grave for hundreds of Noxian and Ionian corpses. Something terrible and unnatural had happened here, something that no single blade could have stopped. The land itself seemed tainted by it.

Sobered, Yasuo returned to the school the next day, only to be surrounded by the remaining students, their swords drawn. Elder Souma was dead, and Yasuo found himself accused not only of dereliction, but of murder. He realized the true killer would go unpunished if he did not act quickly, so he fought his way free, though he knew this would all but confirm his apparent guilt.

Now a fugitive in war-torn Ionia, Yasuo sought any clue that might lead him to the murderer. All the while, he was hunted by his former allies, continually forced to fight or die. This was a price he was willing to pay, until he was tracked down by the one he dreaded most—his own brother, Yone.

Bound by honor, they circled each other. When their swords finally met, Yone was no match and, with a single flash of steel, Yasuo cut his brother down.

He begged forgiveness, but Yone’s dying words were of the wind techniques responsible for Elder Souma’s death, and that his brother was the only one who could have known them. Then he fell silent, passing on before he could grant any absolution.

Without master or brother, Yasuo wandered the mountains distraught, drinking away the pain of war and loss, a sword without a sheath. There in the snow, he met Taliyah, a young Shuriman stone mage who had fled the Noxian military. In her, Yasuo saw an unlikely student, and in himself, an even more unlikely teacher. He trained her in the ways of elemental magic, wind shaping stone, embracing at last the teachings of Elder Souma.

Their world changed with rumors of a risen Shuriman god-emperor. Yasuo and Taliyah parted ways, though he gifted her the treasured maple seed, its lesson now learned.

As she returns to her native desert sands, Yasuo has set out for his own village, determined to put right his mistakes...

"Death is like the wind—always by my side."

-  Yasuo


When I was a child, my brother asked me: “Does the wind flee, or does it follow?”

For a long time, I chose to run, for death followed at my back. The people hunting me once called me their friend. Now, when they draw their blades, they call me murderer.

One by one, they find me. The first was a swordsman of strength renowned throughout Ionia. When we were young, I saw him cleave a tree in two with a single swing of his blade.

But he could not cleave the wind.

The second was a warrior of speed and grace. Agile and cunning, she outran the clever foxes in the woods.

But she could not outrun the wind.

The third was a man of compassion. He taught me the meaning of patience when I was just a prideful child.

My guide. My friend.

My brother.

How long can I keep going? Even the strongest wind eventually dies.

But until then, I will not flee. I will follow the truth. Let the wind guide my blade, and lead me to the true murderer—the one responsible for the blood on my hands.


What is a sword without the man behind it? Teaching a swordsman to kill is simple. The true challenge lies in teaching him not to kill.

When I watched my young brother begin training, he breathed life into the blade at first touch. One heard whispers in the halls comparing him to the sword masters of old. But as Yasuo grew and his skills increased, so did his ego. He was impetuous and boastful. He ignored our masters’ lessons, and knew nothing of patience.

Fearing my brother had strayed too far from the way, I went not to warn him, but to make an appeal to his honor. I gave him a maple seed, our school's highest lesson in humility... one Yasuo seemed to have forgotten. A seed is just a seed, but given time one may come to know the beauty it holds within.

Yasuo took my gift, and the following day he pledged himself to the Elder Souma. I had high hopes he would learn the patience and virtue required of a true swordsman.

It was not to be.

Today, it seems clear to me that Yasuo murdered the very person he was sworn to protect. He has betrayed his nation, his friends, and himself. Were it not for my actions, I wonder if he would ever have been swept down this dark path.

But my task is not to question. I must bear the burden of my duty.

At first light tomorrow, I will set out to capture a sword without a sheath: my brother Yasuo.

Yasuo is a man of resolve, an agile swordsman who wields the wind itself to cut down his foes. This once-proud warrior has been disgraced by a false accusation and forced into a desperate fight for survival. With the world turned against him, he will do everything in his power to bring the guilty to justice and restore his honor.

Formerly a brilliant pupil at a renowned Ionian sword school, Yasuo was the only student in a generation to master the legendary wind technique. Many believed he was destined to become a great hero. However, his fate was changed forever when Noxus invaded. Yasuo was charged with guarding an Ionian Elder, but, foolishly believing his blade alone could make the difference, he left his post to join the fray. By the time he returned, the Elder had been slain.

Disgraced, Yasuo willingly turned himself in, prepared to pay for his failure with his life. He was shocked, however, to find himself accused not just of dereliction, but of the murder itself. Though confused and racked with guilt, he knew the assassin would go unpunished if he did not act. Yasuo raised his sword against the school and fought his way free, knowing his treason would turn all of Ionia against him. Left truly alone for the first time in his life, he set out to find the Elder's real killer.

Yasuo spent the next several years wandering the land, seeking any clue that might lead him to the murderer. All the while, he was relentlessly hunted by his former allies, continually forced to fight or die. His mission drove him ever forward, until he was tracked down by the one foe he dreaded most - his own brother, Yone.

Bound by a common code of honor, the two warriors bowed and drew their swords. Silently they circled one another under the moonlight. When they finally charged forward, Yone was no match for Yasuo; with a single flash of steel he cut his brother down. Yasuo dropped his weapon and rushed to Yone's side.

Overcome with emotion, he demanded to know how his own kin could think him guilty. Yone spoke: The Elder was killed by a wind technique. Who else could it be? Understanding swept over Yasuo as he suddenly realized why he had been accused. He professed his innocence once more and begged his brother's forgiveness. Tears streamed down Yasuo's face as his brother passed in his arms.

Yasuo buried Yone under the rising sun, but could take no time to mourn. Others would be after him before long. His brother's revelation had given Yasuo newfound purpose; he now had the clue that would lead to the true killer. Swearing an oath, he gathered his belongings and, with one last look at Yone's grave, set out with the wind at his back.

"The story of a sword is inked in blood."

-  Yasuo

BASE ARMOR : [24.71] 30
BASE HEALTH : [517.76] 522

Q stacks expire faster.

Yasuo was already on the cusp of being too powerful and midseason’s cost reductions to critical strike items just pushed him over the edge. We’re reducing the amount of pressure he exerts by sitting on Q stacks to give opponents more chances to play against him.

Steel Tempest.png Q - Steel Tempest

STACK DURATION : [10] 6 seconds

E damage down, now has an AD ratio.

We’re okay with Yasuo maxing Sweeping Blade first if he needs to dodge stuff and be super fast, but we’re not okay with how much damage he gets on top of that mobility. That said, Yasuo’s still supposed to ramp into a late-game carry, so we added a ratio to E so he gets some of that damage back as the game progresses. You gotta earn, yo.

Sweeping Blade.png E - Sweeping Blade

DAMAGE : [70/90/110/130/150] 60/70/80/90/100
RATIO Now has an 0.2 bonus attack damage ratio (does not increase with stacks of Sweeping Blade)

Less Attack Speed per level, higher base Attack Speed. R’s bonus penetration only applies to crits.

Yasuo belongs to the class we’ve been calling Slayers, known informally as ‘melee carries.’ These champions (like Riven or Fiora) are nimble yet squishy duelists with the damage to slay anyone, provided they make proper use of their windowed defensive tools (like Wind Wall or Riposte) to survive. By contrast, Fighters (like Vi or Darius) can take a moderate beating as they dish out their own damage, but lack the agility of a Slayer. But what happens if a Slayer gains the tankiness of a Fighter?

Tank Yasuo happens. While lacking the explosive offense of a crit build, Tank Yasuo's damage and mobility remain above average due to his kit, while his items grant him the durability he normally lacks. We’re looking to break up the trifecta and force Yasuo to commit to just a few strengths (instead of all of them). Defensive builds will retain their stickiness, but see a sharp drop in damage. We’re happy when players adapt their styles to the needs of the game, but when Yasuo (like Ekko and Fizz before him) can cover his weaknesses without making tradeoffs, it’s not a fair experience for anyone.


BASE ATTACK SPEED : [.658] .670

Last Breath.png R - Last Breath

DEEP BREATHING : Bonus Armor Penetration now only applies to Yasuo’s critical strikes
BUGFIX : Fixed a bug that allowed Yasuo to get an extra basic attack when casting Last Breath

A whirlwind of bugfixes.

Yasuo mains are people, too. Kind of.


DROPPED MY SWORD : Fixed a bug where Yasuo could be locked out of his basic attack after casting Sweeping Blade or Last Breath

Steel Tempest.png Q - Steel Tempest

SOFT STEEL : Fixed a bug where Steel Tempest wasn’t always critically striking when Yasuo had 100% crit chance

Wind Wall.png W - Wind Wall

WIND TUNNEL : Wind Wall no longer fails to block projectiles in the instant it was cast, if cast at the same time Yasuo died

Sweeping Blade.png E - Sweeping Blade

SWEPT AWAY : Fixed a bug where Sweeping Blade could be chain-cast on multiple targets without cooldown or cast time if cast while knocked up

Wind Wall works as intended.

Now all of those videos of Gold Card going through Wind Wall can be laid to rest.

Wind Wall.png W - Wind Wall

win wall : Fixed a bug where certain targeted abilities (such as Twisted Fate's Pick-A-Card) would pass through Wind Wall as it spawned

v5.15 Patch Updates


BUGFIX : Fixed a weird instance where Yasuo's Q - Steel Tempest could hit enemies in random spots of the map

Q3 applies on-hits correctly.

"Yasuo's Whirlwind wasn't working the same as the other two casts of Steel Tempest. So we fixed it! Have fun using a tornado to set your enemies on fire."
  • Steel Tempest.png Steel Tempest
    • PROC YOU LIKE A HURRICANE : Steel Tempest's Whirlwind now properly applies on hit effects to the first target

Yasuo's flow shield is stronger at every level, but takes more effort to build early-game.

"While we're excited to give Ionia's roamin' ronin some love, it'd be a lie to say the task was easy. One of League's most complex and stylish champions, the slightest change can instantly turn this wind-waking warrior into a whirlwind of pain. We're increasing the shield's amount at all levels to soften the blows he's had to his early-game, but at the cost of his early flow generation; we want Yasuo players to have ways to be successful but, as always, he'll have to work for them. "
  • Way of the Wanderer.png Passive - Way of the Wanderer
    • SHIELD STRENGTH : 60 - 470 100 - 510
    • FLOW CHARGE RATE : 100% at every level 78/89/100% effectiveness (at levels 1/7/13)

Yasuo moves slightly faster and Steel Tempest has a lower cooldown at early ranks.

"We might have overdone it a tad with 4.18, so we're stepping back just a bit. These changes should maintain Yasuo's vulnerability to ganks in lane but give him a little more leeway to make plays with Steel Tempest. A wanderer isn't always lost, but that doesn't mean he's over-nerfed. What does that mean. We don't know."
  • General
    • MOVEMENT SPEED : 340 345
  • Steel Tempest.png Q - Steel Tempest
    • COOLDOWN : 5/4.75/4.5/4.25/4 seconds 4 seconds at all ranks

Yasuo's base health and movement have been reduced. Remember that time we talked about taking more time to read the summary than the actual changelist?

"As hypercarry swordsman, Yasuo should make early game tradeoffs for opponents to capitalize on before he grows to his late potential. Right now, that isn't quite the case as Yasuo's quite strong in the early game, even in unfavorable matchups, in addition to scaling extremely well. These changes are to more specifically highlight Yasuo's early weaknesses, including being squishier if his passive isn't up and, more importantly, being more vulnerable to ganks if he's pushed up and doesn't have minions to dash through for his retreat. We'll be keeping a close eye on Yasuo with these changes, however, as having an early game weakness will almost certainly have an impact on his late game reliability."
  • General
    • BASE HEALTH 512 ⇒ 462
    • BASE MOVEMENT SPEED 350 ⇒ 340


"While this is a fairly innocuous bugfix for Yasuo, we wanted to take this opportunity to talk about everyone's favorite wind swordsman (to ban). While we think Yasuo's in a good spot in terms of his overarching gameplay and strategic fit, there's a good chance he's just a little strong for what he brings to the table. We're currently examining ways to add more meaningful counterplay against Yasuo but just wanted to let you know we're aware of his power. "
  • Steel Tempest.png Q - Steel Tempest
    • INNOCUOUS BUGFIX Fixed a bug where Steel Tempest's cooldown was slightly too low when using the E-Q combo at high Attack Speeds

'Yasuo's passive shield is slightly shorter, Q scales less with Attack Speed, and W no longer gives bonus flow to E

"We've been watching Yasuo over the past few months and while we don't think he's really out of line, we did some fine-tuning to round him out. "
  • Way of the Wanderer.png Passive - Way of the Wanderer
    • SHIELD DURATION 1.5 seconds ⇒ 1 second
  • Steel Tempest.png Q - Steel Tempest
    • LESS-QUICK-DRAW Steel Tempest now scales less effectively with Attack Speed and has a minimum cast time of 0.13 seconds ⇒ 0.18 seconds. The Attack Speed needed to reach this minimum is unchanged (at 114%, or 60% from items at level 18).
    • BUGFIX Fixed a bug where Steel Tempest's whirlwind was dealing instant damage in the area of a normal Steel Tempest cast as it was traveling out (this is a very minor change)
  • Wind Wall.png W - Wind Wall
    • REMOVED LOW ON FLOW Wind Wall no longer passively grants bonus Flow from dashing


  • Sweeping Blade.png E - Sweeping Blade
    • BUGFIX: Fixed a bug where Sweeping Blade sometimes didn't count as a spellcast for various items and champion abilities

"As a nimble fighter, Yasuo should be balancing his offense and defense throughout the laning phase. Right now, however, Yasuo's ability to stack up excessive amounts of extra damage on Sweeping Blade (particularly at early levels) means he can quickly bully out opponents before they have the chance to retaliate."

  • Sweeping Blade.png E - Sweeping Blade
    • BONUS DAMAGE CAP: 100% at 4 stacks ⇒ 50% at 2 stacks

v4.3 We’ve reduced Way of the Wanderer’s shield duration as well as its value at higher levels.

“We want to further emphasize Yasuo’s defensive weaknesses, like triggering his shield with a basic attack and then waiting out the duration, or making him more vulnerable to lots of things hitting him at the same time.”

  • Way of the Wanderer.png Passive - Way of the Wanderer
    • SHIELD DURATION: 2 seconds ⇒ 1.5 seconds
    • SHIELD (ROUGH VALUES): 60~690 ⇒ 60~470
    • SHIELD (REAL VALUES): 60/65/70/75/85/95/110/125/145/170/200/240/290/350/420/500/590/690 ⇒ 60/65/70/75/80/90/100/110/125/140/160/185/215/250/290/340/400/470

It now takes more movement to generate flow and Sweeping Blade gives less flow when Yasuo dashes. We also reduced Last Breath’s cast range.

We made some general quality of life changes to Yasuo in patch 4.1 , but as players begin to master him, we’ve seen how strong he is when played to maximum effectiveness. We looked at areas where we could reduce some of that power without messing with his core playstyle. We were also unhappy with how Yasuo was using Last Breath to engage in fights by teleporting from thousands (and thousands) of miles away.

  • Way of the Wanderer.png Passive - Way of the Wanderer
    • MOVEMENT TO GENERATE A UNIT OF FLOW :: increased by 15%
  • Steel Tempest.png Q - Steel Tempest
    • VISUALS :: Now passively displays a range indicator around Yasuo when Steel Tempest's Whirlwind is available
  • Sweeping Blade.png E - Sweeping Blade
    • PASSIVELY GRANTS FLOW WHEN HE DASHES :: 4/8/12/16/20% ⇒ 3/6/9/12/15%
  • Last Breath.png R- Last Breath
    • CAST RANGE :: 1300 ⇒ 1200
    • BUG FIX :: Fixed a bug where Last Breath could sometimes be used beyond the maximum range


Summary: We’ve smoothed out Yasuo’s gameplay overall and made Steel Tempest auto-smartcast. Additionally, Last Breath now gives maximum Flow when cast and has a slightly shortened animation.

While we’re still keeping an eye on how Yasuo is performing at all levels, we wanted to smooth out his gameplay and give Last Breath more use to turn around a fight when he’s behind.

  • General
    • Now properly applies the 10% critical strike damage reduction to Statikk Shiv critical hits
