Hi, my party is Cloud(63), Vincent(62) and Cid(61) and I'm fighting Sephiorth. I can get to his last form and he kills me. I have Kotr but only at lvl 1, and I'm too lazy to level it for another 46000 Ap. Any tips on beating him? I've dealt him around 150k damage total in 1 go before, Kotr, BahaZERO, Neo, Baha, Phoenix, F2, I2, B2, Q2, Bi2, Haste>, Shadow Flare ES, Aqualung ES, Magic Breath ES, etc. He just won't die!!
