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, changed to Inferno in Origins and renamed to Blaze in Dawn of Souls and onward, is an attack used by Chaos. It deals fire-elemental damage to the whole party. It has a power of 96 and an accuracy of 32.
Inferno is the ultimate attack for Ifrit, which deals Fire elemental damage to all enemies. It has a spell power of 128.
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 Nintendo DS release allowing anyone to learn the skill.
Rubicante once again 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 used by Chaos Bahamut during both encounters and Caius uses the ability during the third phase of the final battle against him, as well as in his earlier battles with the Paradox Scope skill activated.
In the battle against Caius, he will use Inferno while in Ravager stance. The ability functions like in Final Fantasy XIII-2.
Despite being named Inferno, the ability is actually the summon Ifrit's trademark attack, Hellfire, and is named such in the Japanese version. Inferno 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.
Gabranth's Inferno returns as one of the possible final attacks of his EX Burst. Vaan has Inferno as an HP attack, where he creates a crest of fire and charges towards opponents wreathed in flame. It costs 30 CP to equip and 140 AP to master.
Rubicante also reappears as a summon. He can bought from certain Moogle Shops.
