Ultemica is easy on her first time, though if you use GF's she can instantly K.O. them. Griever now right there he is the pain, him and his shockwave pulser just bite major. If you have someone with the revive ability use it along with recover, lucky for me on like my 5th try though I had those two people since the very begining. After Griever falls the rest of the fight is a breeze cause the game has it programmed that Squall will use Lionheart everytime.
