Ultimate Illusion (究極幻想, Kyūkyoku Gensō?) is a recurring ability mostly associated with Gilgamesh. It is often used as his Limit Break or ultimate ability in his appearances. Ultimate Illusion was not used in his original appearance in Final Fantasy V, but in Final Fantasy XII.
Ultimate Illusion also appears as the ultimate attack of Ultima, the High Seraph. Functioning as a phase change attack, Ultima's version will inflict continuous heavy damage to the entire alliance party. In order to survive the attack, players must destroy the Ruination target and have healers heal through the massive damage. The attack is successfully disrupted when Ramza stops Ultima from using the attack.
Ultimate Illusion appears as the most powerful of Gilgamesh's card abilities.
"Ultimate illusion" is a synonym for "final fantasy".
