Blue Mage

Blue Mage, also known as Gun Mage , or Vampire is a job in the Final Fantasy series, first introduced in Final Fantasy V.

Profile
Blue Mages, as their name implies, focus on Blue Magic, a special subset of Magic that allows them to use attacks otherwise exclusive to enemies. While an odd choice, Blue Mages often have a wide range of usefulness due to the varied spells they gain. Blue Mages usually learn Blue Magic by having enemies (or occasionally, another Blue Mage ally) use it on them, but some games have other methods to learn their magic. Blue Mages benefit greatly from the ability to Control monsters, reducing the chance involved in waiting for a monster to use their skill on the Blue Mage.

Beyond this, Blue Mages vary in equipment and physical prowess. They are not as weak as other Mage classes in terms of attack or defense, and are usually capable fighters. Of course, their true strength is their magic. As with most of the other mage classes, Blue Mages usually wear clothes and cloaks which match their magic color (blue, in this case), sometimes with a mask.

Trivia

 * In Final Fantasy IV: The After Years there is some evidence in the source code of the game that suggests Harley was originally intended to be a Blue Mage.
 * The class's mechanics of using enemy only abilities, and its signature color of blue, appears to draw similarities to the Capcom mascot and heroic protagonist Mega Man.
