Barbariccia fights no different from how she did in Final Fantasy IV, even though her attacks may be significantly stronger. Like before, she will counter any attacks while she is protected by her tornado. The only way to cancel it is with Kain's Jump ability. Fighting her without the assistance of it will be difficult. She still has Maelstrom, which reduces the party's HP to single digits. When Barbariccia is weakened, she will cast Tornado on herself and can then be finished with one more hit.
Barbariccia is a demon in the Inferno of Dante's Divine Comedy. He is one of the 13 Malebranche ("Evil Claws") who guard Bolgia Five of the eighth circle of Hell, Malebolge. Vulgar and quarrelsome, their duty is to force the corrupt politicians to stay under the surface of a boiling lake of pitch.
His name means "Curly Beard."
