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.
