In Kingdom Hearts Birth by Sleep Final Mix, Illusion-R is a Friendship Command that takes up two slots in the Command Deck and has a maximum level of 3. Using Illusion-R command transforms the user into a Ringer and grants them its abilities. The transformation lasts until the Illusion Gauge empties or the user uses the Revert command.
