Yasuo thrusts forward with his sword, damaging all enemies in a line. Successfully landing Steel Tempest grants Yasuo Gathering Storm stacks for a short period. The third stack of Gathering Storm causes Steel Tempest to send out a whirlwind that travels in a line and sends all enemies caught Airborne. If Yasuo casts Steel Tempest during Sweeping Blade, the ability strikes all enemies immediately around him.
