Gadgeteer(カラクリ士,Karakurishi?) is a Job class from Final Fantasy Tactics Advance. It is only available to Moogle characters after mastering two Thief skills. Gadgeteers rely on the tricks held within Pandora's Box, learned by knuckles, for their special skills. However, there is a catch: the Pandora ability may affect all members of your team or the rival team.
What side is affected is determined by the coin that comes out of the Gadgeteer's box. If the coin's face is a sun, the ability will affect your team. If the coin face is that of a crescent moon, the ability will affect the opposition. In order to guard against hurting your own allies, use equipment that guards against debuffs. The very useful Angel Ring provides a nullification against Blind, Poison, and Doom, which account for three out of four offensive Pandora "spells".
The Gadgeteer is the most defensive Moogle job. Its Defense stat ties with the Mog Knight, while its Resistance ties with the Nu Mou Black Mage for highest Resistance in the game. It also ties with the Animist for highest HP in a Moogle job, making it the ideal tanking job for Moogles. However, its Attack, Magic Power and Speed, while not horrible, leave something to be desired.
The Gadgeteer's Pandora's box item is likely a reference to the Greek myth of the same name, where the first woman, Pandora, opened a container (actually a large jar) that released all the evils of the world.
