Katarina throws a Dagger at the target that then bounces to nearby enemies before ricocheting onto the ground.

Katarina gains a burst of Move Speed, tossing a Dagger into the air directly above herself.

Katarina blinks to the target, striking it if its an enemy, or striking the nearest enemy otherwise.

Katarina becomes a flurry of blades, dealing massive magic damage while she channels to the 3 nearest enemy champions.
