You must mean Trema. **** his hp is really 999,999hp so i get what you mean. He is really hard to beat belive me it took me ages. Cast protect on all party members to stop his attacks. Try to lower his hp down so he does not cast demi flare or ultima on you. Use soul ring to reduce his mp to 0 aswell. He will not use any magic then.remember if your mages are running out of mp or anyone else just steal his turbo ether and his ether. Good Luck mate and you need more help just ask.
