Terra using Chaos Blade in Olympus Coliseum.

Chaos Blade (カオスレイヴ Kaosu Reivu?, lit. "Chaos Rave") is a technique in Kingdom Hearts Birth by Sleep usable by Terra. The ability is identical to Sonic Blade, except it is slower, deals more hits, is stronger, and can attack multiple enemies via teleporting between strikes. It also has a chance of binding or blinding enemies.


In Kingdom Hearts Birth by Sleep, Chaos Blade is an Ultimate Attack Command that takes up two slots in the Command Deck, has a maximum level of 6, a normal reload time of 25 seconds, and fills the Command Gauge by 15%. It is considered a Darkness-aligned attack, and as such will active the Dark Impulse Command Style, if available.

Chaos Blade is a Ultimate-class Attack Command that can be melded through only one recipe, listed in the Giga Attack Recipe.

  • The first recipe is a B recipe, can only be melded by Terra, and has a 20% chance of transforming into Ars Solum when melding.
