in Disc 2 i believe the first boss is a twin-headed fire/ice dragon. i've tried doing everything i can to defeat him, but the most i got was one head (i think the fire-using one). i've tried using my strongest members (Cloud, Cid, and Cait Sith), and then swapped Cid for Barret because i thought that his second Lv 1 limit break, Mind Blow, would sap up their magic but i still couldn't do it. any advice?
