Innate: Whenever an enemy champion dies within 3 seconds of Katarina damaging them, her cooldowns are reduced by 15 seconds.
Sinister Steel: Whenever Katarina retrieves a Dagger, she uses it to slash through all nearby enemies, dealing 68 - 240 (based on level)(+ 100% bonus AD)(+ 55 / 70 / 85 / 100% AP)magic damage and reducing Shunpo's cooldown by 78 / 84 / 90 / 96%.
Daggers last 4 seconds before disappearing.
Voracity's cooldown reduction will still take effect even after Katarina dies.
Katarina can use Shunpo on Daggers in mid-air.
However, the damage will not apply until it lands.
