Katarina’s New Abilities
Voracity (Passive): Champion kills or assists reduce Death Lotus' cooldown and refresh your basic abilities.
Bouncing Blades: Katarina throws a dagger that bounces from enemy to enemy, dealing magic damage and marking them. Striking a marked target with an ability or basic attack will consume the mark to deal additional magic damage.
Sinister Steel: Katarina whirls her daggers around her, dealing magic damage to all enemies in the area. If she hits an enemy champion, Katarina gains Movement Speed for a short duration.
Shunpo: Katarina instantly moves to her target's location and takes reduced damage from enemies for a short duration. If the target is an enemy, she deals damage.
Death Lotus (Ultimate): Katarina becomes a flurry of blades, throwing daggers with unrivaled speed at up to three nearby champions. Daggers deal magic damage and reduce incoming healing on targets hit.
