Cosmic Ring

Cosmic Ring is an accessory that can be obtained in Kingdom Hearts II. It offers the strongest possible boost to AP available (excepting, obviously, the Final Mix + exclusive Executive Ring), granting eight points on the character it is equipped to, and making it more powerful than the Master's Ring or Cosmic Arts. It is one of three accessories found in a chest during Sora's part of the game, the other two being the Draw Ring and Skill Ring.
