VI Degenerator is the Japanese name of Banisher, an attack usable through the Magitek command when riding Magitek Armor. Banisher removes a target enemy from battle, stalling its final attack for 1 turn. It has a hit rate of 120 but fails on targets immune to Death. In the mobile and Steam version, Banisher is classified as an Attack magic.
VIII Degenerator is a Blue Magic Limit Break for Quistis. The spell is similar to Warp, as it sends the selected enemy into another dimension. Degenerator never misses, but Grats, Vysages, Lefty, Righty, Cactuars, Tonberries, Esthar Soldier (Terminator) (although Quistis can't fight these enemies), UFO?, PuPu, and bosses (except Oilboyle) are immune to it. Using Degenerator on the Island Closest to Heaven and the Island Closest to Hell is a quick way to level up the characters.
