Chaos Blade (カオスレイヴ Kaosu Reivu?, lit. "Chaos Rave") is an Attack Command for Terra in Kingdom Hearts Birth by Sleep. Gameplay-wise, it is identical to Sonic Blade, while although slower, deals in more hits, is stronger, and can attack multiple enemies via teleporting between strikes. It also has a chance of blinding or binding enemies.
