Fira

Fira (Japanese: ファイラ Faira) is an upgrade over the Fire spell. It appears in most Final Fantasy games, and it first appeared in Final Fantasy. Like the Fire spell, Fira is a Black Magic spell which is usually associated with Black Mages.

Final Fantasy
In Final Fantasy, Fira can be learned from the Level 3 Black Magic in Elfheim. When used, Fira inflicts medium fire damage on all opponents. Fira uses 15 Magic Points for each use. In the original Nintendo Entertainment System version, the Fira upgrade cost 1,500 gold, and in the Final Fantasy I & II: Dawn of Souls remake, its price was reduced to 1,000 gil.

Fira was originally named FIR2 in the Nintendo Entertainment System release and Fire2 in Final Fantasy Origins.
