Degenerator
From Final Fantasy Wiki
Degenerator is a Blue Magic spell only usable by Quistis. The spell is similar to Warp, as it sends the selected enemy into another Dimension and is instantly KO'd. This spell never misses, but most bosses and the monster Tonberry are immune to it. Even with these instances, using this skill on the Islands of Heaven and Hell is a quick way to level the characters.
Degenerator is learned from the item Black Hole, which can either be obtained from the monster Gesper or using Card-Mod on the Gesper Card or the Diablos Card.
