Augment (Final Fantasy IV)

The Augment Ability System is the support ability system for the 3D versions of Final Fantasy IV.

Mechanics
Augments allow characters to inherit and equip abilities from other characters. While some have several effects, such as Counter, others add new commands, including Sing or Twincast.

A character can have as many augments as the player wants, but they can only equip four augments at once in the main command list, since Items cannot be removed. A fifth ability can be attached in the Auto-Battle command, but it will not alter the character's stats and the player must activate Auto-Battle to use it.

An augment is received as a Key Item and is used from the inventory to impart it to a character, and cannot be used again. If the player imparts more than one augment on a guest character, they will meet the requirements to obtain other augments. For example, if the player gives Edward an augment, he will give them Salve, in addition to just Bardsong.

It is impossible to receive all of the augments in one playthrough, as there are not enough to share early in the game. Because of the limited number of augments that can be obtained up until Cecil's fight with Cagnazzo, the player cannot give Edward two augments and have enough left over to give three to Palom and Porom. Thus, the player must give up either the Hide or Dualcast augment. During subsequent playthroughs with New Game+, this is not a problem as the player will retain their augments from the previous playthrough. Some augments, such as Treasure Hunter, cannot be obtained more than once.

List of Augments
Augments are sorted by the earliest possible time they can be obtained in the storyline.

Stat Bonuses
Every ability in the game grants stat bonuses at level up from level 71 on up. However, it is not enought to just give the Augments to the characters. These Augments must be equipped in battle for the stats to be added once the characters level up. Also, placing these Augments or Commands in the Auto-Battle slot will not grant the stat bonuses upon levelling up.
