Katarina Ability (LoL): Voracity

Takedowns on enemy champions within 3 seconds of being damaged by Katarina reduce her abilities' current cooldowns by 15 seconds.

Whenever Katarina retrieves a Dagger, she uses it to slash around herself, dealing 68−240 (+0.75 per attack damage) (+55 / 66 / 77 / 88% of ability power depending on level) magic damage (depending on level) to enemies struck and applying on-hit effects to all of them, as well as reducing Shunpo's current cooldown by 78 / 84 / 90 / 96% (depending on level).

Daggers take 1 second to land, and will disappear after being on the ground for 4 seconds.
