Yasuo is a man of resolve, an agile swordsman who wields the wind itself to cut down his foes. But 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.

Once 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, 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. Now 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.

This guide is a work in progress. It's going to be about the newest addition to the League - Yasuo, The Unforgiven. Since I will work with this guide on regular basis, please don't downvote! Be constructive with ur feedback in the comment, and I will fix what the problem is! :)

Note: I will add pictures later

Passive: INTENT: Yasuo's critical strike chance is doubled, but the damage dealt by his critical strikes is reduced by 10%. RESOLVE: At maximum Flow, the next time Yasuo would take damage from a champion or monster he first converts his Flow into a shield that absorbs damage. After 2 seconds, if not already depleted, Yasuo's loses all his Flow.

Q: FIRST ACTIVE: Yasuo thrusts his sword forward, damaging all enemies in a 475-unit line. If cast while dashing, the area of effect is charged to a ~375-radius circle. SECOND ACTIVE: Same as the first active. THIRD ACTIVE: Yasuo brandishes his sword causing a whirlwind to tear forward, damaging and knocking airborne all enemies in a ~900-unit line. If cast while dashing, the area of effect is changed to an ~375-radius circle. This active resets the chain. Steel Tempest can critically strike, dealing additional physical damage based on X% AD. Additionally, on-hit effects will be applied to the first enemy hit within 475-unit range. The cooldown and cast time of Steel Tempest is reduced based on Yasuo's bonus attack speed and unaffected by cooldown reduction.

W: PASSIVE: Yasuo generates a percentage of his maximum Flow whenever he uses Sweeping Blade or Last Breath, in addition to the amount that is generated for the distance moved. ACTIVE: Yasuo creates a wall of wind that slowly drifts forward over the next 3.75 seconds. The wall blocks all enemy projectiles, except tower hits

E: ACTIVE: Yasuo dashes 475 units in the direction of the target enemy, dealing magic damage and marking them briefly. Each cast increases the next dash's base damage by 25%, up to 100% bonus damage. Yasuo cannot use Sweeping Blade on an enemy that's already been marked.

R: ACTIVE: Yasuo blinks to the nearest airborne enemy champion to the cursor. Upon arriving, he suspends all airborne units within a 400-radius of his target in the air for 1 second while dealing physical damage to all of them. Once he lands, Yasuo gains 50% penetration to bonus armor for 15 seconds. Casting Last Breath will reset the chain on Steel Tempest.

Yasuo is usually played as a solo laner, mid or top. Alternatively, he can be the AD carry bot lane or the jungler, but neither is recommended due to the difficulties. As a damage source for his team, Yasuo can quickly become lethal by purchasing crit chance, attack damage and attack speed.

Because Yasuo's Way of the Wanderer will double his crit chance and his Steel Tempest may crit, every item that provides crit becomes more gold efficient in his hands than any other item in the game.

• Infinity Edge, Statikk Shiv and Six Greater Marks of Critical Chance will total 100% but at a cost of 6300 gold. Because Statikk Shiv is built from Avarice Blade, this is the fastest path possible due to the bonus gold generation.
  
• Statikk Shiv, Infinity Edge, and Trinity Force would also give you 110% crit chance (which is capped at 100%) as well, though the cost is relatively high (10003 gold in total). It provides you with stats suited for a more ability based playstyle.
  
• Alternatively, Infinity Edge and Phantom Dancer together will give you 110% crit strike chance. At a combined cost of 6600 gold, Yasuo can reach this mark somewhere in the mid-game, but do note that it will give you only 5% extra movement speed but the given built above will give you 14% movement speed and more passives + actives effects that could be easily exploited by Yasuo.
