Katarina Ability (LoL): Voracity

Whenever an enemy champion dies within 3 seconds of Katarina damaging them, her abilities' cooldowns are reduced by 15 seconds.

Whenever Katarina retrieves a Dagger, she uses it to slash through all nearby enemies, dealing 68−240 (depending on level) (+1.0 bonus attack damage) (+55 / 66 / 77 / 88% of ability power (at level 1 / 6 / 11 / 16) magic damage and reducing Shunpo's cooldown by 78 / 84 / 90 / 96% (at level 1 / 6 / 11 / 16).

Daggers last 4 seconds before disappearing.
