Yasuo Ability (LoL): Sweeping Blade

Yasuo dashes through a target, dealing 70 / 85 / 100 / 115 / 130 (+60% of ability power) (+0.2 per bonus attack damage) magic damage. Each use of this ability grants 25% bonus damage to the next use for 5 seconds, stacking up to 100%. If Steel Tempest is cast while dashing, it will strike as a circle. This ability can only be cast on the same target once every few seconds.
