Skarner Ability (LoL): Crystal Slash

Skarner slashes around himself, dealing physical damage equal to 1 / 1.5 / 2 / 2.5 / 3% of target's maximum health (+0.20 of attack damage) to all surrounding enemies.

If an enemy is hit, subsequent uses of Crystal Slash within 5 seconds deal bonus magic damage equal to 1 / 1.5 / 2 / 2.5 / 3% of target's maximum health (+0.20 of attack damage) (+30% of ability power) to the target.

Basic attacks against non-structures reduce Crystal Slash's cooldown by 0.25 seconds, quadrupled to 1 against enemy champions.
