Abilities (KHII)

The Ability system in Kingdom Hearts II has received both minor aesthetic upgrades, as well as major mechanical changes. An Ability can now be equipped or unequipped simply by pressing while highlighting its entry in the Ability menu, and are now separated into Action, Growth, and Support sets, which are distinguished by the color of their entry. Action Abilities are those which are used directly in combat, and are often tied to button-presses, while Support Abilities are those which enhance the character's stats, and are often passive. Kingdom Hearts II also expands Abilities such as Dodge Roll and Glide into Growth Abilities, which affect Sora's movements, and can be upgraded by leveling up his Drive Forms. Kingdom Hearts II also introduces Equipment Abilities, which are automatically equipped when using a specific weapon. These abilities require no AP, though they are not able to be replaced or unequipped without taking off the weapon as well. while each of his Keyblades possesses a Support Ability. Donald and Goofy's strongest weapons also possess Equipment Abilities, as well as some of the rarer Armors and Accessories.

While Sora can still learn most of his Support and Growth Abilities through leveling up, all of his standard Action Abilities are learned after completing certain events. However, allies no longer gain abilities by leveling, and instead gain them solely from events. Finally, each of Sora's Forms possesses its own Ability set, which temporarily replaces his normal set of Action and Growth Abilities; while the Forms also possess unique Support Abilities, they do not replace those that equipped to Standard From. Like Equipment Abilities, the Abilities belonging to each Form require no AP, though they cannot be replaced or unequipped. These Ability sets also include the Growth Ability linked to that Form, in a version stronger than Sora can use in Standard Form.

The AI used to determine when allies use their Abilities has also been made more controllable. Each Action Ability can now be switched between frequent, moderate, rare, and no use.
