Magic (Final Fantasy)

There are two types of magic in Final Fantasy: White Magic and Black Magic. White Magic is the specialty of White Mages, but can (to some extent) be used by Knights. Black Magic is the specialty of Black Mages, but can be used (again, to some extent) by Ninjas. Red Mages can use most of both Black and White Magic. Magic in this game is unique in the fact that it's one of the few games in the series to not use MP, and instead goes by a use system. Each level of magic has a set amount of uses, and after a character has used so many spells, that character will be unable to cast any magic from that level until they have refilled their HP at an Inn, or Cottage (House in NES release). In the GBA and PSP remakes, this is changed to MP.
