AP

AP (Ability Points) are points that are used in the Kingdom Hearts series to equipped the game's characters with abilities. The overall AP can be increased by leveling up, using items such as AP Boost, or wearing equiptment that will increase the overall AP. If the player does not have enough AP, they cannot equipt certain skills until they have more AP or take off other abilities.

In Kingdom Hearts: Chain of Memories, AP is not used in Sora's gameplay, rather, it is replaced with "Learn Sleight" status growth. However, in Reverse Rebirth, AP make an appearance as "attack points" in Riku's gameplay. The higher Riku's AP is, the stronger his attacks is.
