Book of Retribution

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. When performing an A+A+A+A combo, Zexion executes it with the usual slam, then two horizontal slams, then Zexion throws the Book around. When using A+Y+Y+Y, Zexion uses the normal slam, then an upper slam, then a vertical slam (in midair), then the Cloaked Schemer throws throws Ignes Fatui: Another Side spinning forward. When performing the aerial combo, Zexion attacks using two vertical slams, then throws his Lexicon spinning forward.
