Black Hole Finisher
After doing his basic three hit combo, Raven summons out a small black hole from his claw to stun and hold the enemy while he does up to 4 quick slashes. Raven then lets go of his claw and the black hole explodes, launching the enemy away.
Note: There is a glitch where if hit by an enemy and if a "Super armor for x seconds when attacked" effect activates you can keep slashing for an extended period of time.
Post 1/17 KR patch:
This combo is now cancel-able by skills or simply pressing L.jpg or R.jpg.
