First and Second cast: Yasuo thrusts forward with his sword, dealing 20 / 45 / 70 / 95 / 120 (+1.0 per attack damage) physical damage to all enemies in a line. Successfully landing Steel Tempest grants Yasuo Gathering Storm stacks for 6 seconds.

Third Cast: The third stack of Gathering Storm causes Steel Tempest to send out a whirlwind that travels in a line of 900 range and sends all enemies caught Airborne. This whirlwind deals 20 / 45 / 70 / 95 / 120 (+1.0 per attack damage) physical damage to everyone hit.

If Yasuo casts Steel Tempest during Sweeping Blade, the ability strikes all enemies immediately around him, having a radius of 375 instead.

Steel Tempest can critically strike for 160% damage and apply on hit effects for the first target hit. The ability is also unaffected by cooldown reduction, instead, the cooldown and cast time is reduced by Yasuo's attack speed.
