Ultima is a recurring spell in the Final Fantasy series, usually classified as a Black Magic spell with the exception of Final Fantasy II where it is classified as a White Magic spell. It is often the most powerful spell in the game, hitting all enemies for non-elemental damage, which can ignore defense, Reflect and any other protection. Ultima usually manifests as an explosive sphere of blue or green energy consuming opponents.
Ultima can be obtained through a vague sidequest or by reaching level 80 with Oalston.
