Corki Ability (LoL): Missile Barrage

Corki fires a missile that explodes on the first enemy hit, dealing 80 / 180 / 280 (+0.8 per attack damage) physical damage to surrounding enemies. Every third missile instead deals 160 / 360 / 560 (+1.6 per attack damage) physical damage.

This ability has up to 4 charges. Basic attacks on-hit against champions reduce the time between charges by 2-4 seconds (depending on critical strike chance).
