Inferno(インフェルノ, Inferuno?) is a recurring ability in the Final Fantasy series. It is usually a powerful Fire-elemental spell, and is both an enemy ability and an attack usable by the player in some games. It is not to be confused with Hellfire, Ifrit's trademark attack, which was translated as "Inferno" in some games.
Inferno is an enemy attack that does massive Fire-elemental damage to all party members and enemies. It is Rubicante's signature attack, and is also usable by Geryon. Inferno is also usable as an augment in the 3D versions allowing anyone to learn the skill.
Rubicante uses Inferno as his trademark attack. It is also a Band ability learned in a cutscene battle with Rubicante before the player fights Ifrit. Inferno is usable by combining Rydia and Edge's abilities.
Inferno is an enemy ability that deals heavy fire-based damage and inflicts Wound damage. It is used by Chaos Bahamut (both encounters) and Caius (final battle third phase and earlier battles with Paradox Scope skill).
Inferno (Hellfire in Japanese version) is a pet ability available to level 50 Summoners that causes Ifrit-Egi to deal fire-elemental damage to all enemies within an area of effect with the potency of 200 and also deals fire damage over time with a potency of 20 for a period of 15 seconds.
