Book of Retribution

The Book of Retribution (裁きの書) is a Lexicon that can be wielded by Zexion 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, VI being Zexion's rank within the Organization.

Gameplay
While the Book of Retribution is one of Zexion's stronger lexicons, it is slightly unwieldy, as the combo finisher of his ground combo is bit difficult to execute, and it does not have the attack range that some of his other weapons do. When he is on the ground, Zexion's ground-combo comprises of a forward slam, twin horizontal slams, and then a forward toss of the Book of Retribution. When Zexion is in the air, he will smack enemies twice in a left-to-right fashion, again throwing the lexicon forward. Pressing will cause Zexion to perform both a foward and upper slam, the -combo ending with a toss of the Book of Retribution, his aerial combo's combo finisher.

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".

A “book” is a collection of bound paper containing written material or illustrations. All of Zexion’s weapons are lexicons—a type of book—and many are named after other types of books. “Retribution” is a synonym for “vengeance”.

Trivia

 * In Kingdom Hearts 358/2 Days, before one departs on a mission, Zexion can sometimes be seen reading the Book of Retribution when he is in the Grey Area.
