Final Fantasy X Remaster - Boss: Dark Magus Sisters

Cindy and her Camisade...Forget Three Stars, only helps when not dead. You can fight the Magus Sisters within two optional ways: Fighting them the hard way with all three of them at the same time, or splitting them up by running away from them. Grouping them will use their Delta Attack which does 99,999 damage and ignores Auto-Life. Mega-Graviton is used instead when fighting them one by one.
