Book of Retribution

The Book of Retribution (裁きの書) is a form of Zexion's Lexicon in Kingdom Hearts 358/2 Days. In Kingdom Hearts Re:Chain of Memories and Kingdom Hearts II Final Mix, the Book of Retribution is his only weapon. The Book of Retribution is volume VI of a work titled Ignes Fatui: Another Side ("ignes fatui" being Latin for "delusions"; titled Hallucination: Another Side in the Japanese version). Another Side is the name of the music played during Kingdom Hearts Final Mix 's secret scene, Deep Dive. Also, a hallucination is also known as an illusion, which is Zexion's attribute and VI is Zexion's rank within the Organization.

Gameplay
When performing a ground combo, Zexion executes it with the usual slam, then two horizontal slams, then Zexion throws the book around. When using the extensive ground -combo, Zexion uses the normal slam, then an upper slam, then a vertical slam (in midair), then he will throw the Book of Retribution spinning forward. When performing the aerial combo, Zexion attacks using two vertical slams, then throws his Lexicon spinning forward.

Design
It is unclear exactly what the pages of the Book of Retribution contain, but from what can be seen, it tells some sort of story and lacks a basic dictionary layout. It is mostly black. The cover displays three white, interconnected Nobody symbols. The back bears the outline of another Nobody logo. The spine of the book displays a Roman number six (VI), along with the title "Ignes Fatui: Another Side" ("ignes fatui" meaning "delusions" in Latin), superimposed over yet another Nobody symbol. In the Japanese version, "Ignes Fatui" is replaced with "Hallucination", a synonym for "delusion".

Trivia

 * Also in Kingdom Hearts 358/2 Days, Zexion can sometimes be seen reading the Book of Retribution when he is in the Grey Area.
