Magic refers to any supernatural phenomenon conjured into being from an individual's Magic Points. It is created from a form of mystical energy that is quantified in the game by a mob or player's MP statistic, a portion of which is consumed with each magic spell cast. When a magic user's store of MP is depleted, he or she will be unable to conjure any more spells. People in Eorzea who practice magic are referred to as Disciples of Magic.

Magic can have a variety of effects, ranging from healing and enhancing to damaging and enfeebling.
