This fight wasn't too difficult, but some of the special attacks that the boss uses can be pretty brutal. Use Items often and don't be afraid to use your large healing potions if necessary. Grossing the boss out seemed to be pretty effective, but killing them quickly is the key here. You'll want to be as perfect as possible with blocks (I would've been dead in one turn at one point in the fight if I hadn't blocked successfully) and attacks. It wasn't all that difficult though so long as you're comfortable with the game. I beat the boss on the first try.
This is the PS3 version of the game.
