Augment (Final Fantasy IV)

The Augment Ability system is a support ability system from Final Fantasy IV on the Nintendo DS. It allows each character to equip abilities that have several different effects, such as Counter, although some do add new commands, such as the Sing or Twin command.

An Augment Ability is received as a Key Item. For a character to learn the ability, the item must simply be used on them. However, once the item is used, it can't be used again.
