Arcane Compendium

 The Arcane Compendium is a Lexicon that is found in Kingdom Hearts 358/2 Days. It is the form Zexion's Lexicon takes when equipped with the Loaded Gear. It is a black book with a blue tri-Nobody symbol on the covers and a yellow border. It has a four-hit combo in which it is bashed on top of an enemy and then swung from right to left, finally ending with it being swung behind Zexion and hitting the enemy. Its three-hit combo consists of it being bashed on top of an enemy and then hitting them on their left side, finally ending with it being carried in the air. It does not summon anything from its pages.

Design
The Arcane Compendium lexicon is rectangular with curved corners on the ends of the covers, as well as a concave edge on each cover. Both the top and bottom edges of the spine are also concave. The both covers share a blue, three-pronged symbol superimosed over a yellow ring. The three-pronged symbol is vaguely remenicent of the three interconnected Nobody symbol design on the front cover of the Book of Retribution. The corners of the spine each sport a slightly curved, blue rectangle, each with a yellow border. The lexicon itself is mostly black and also has a yellow border.
