This part is rather difficult and the easiest way is to dodge all of his regular attacks. Keep running away and when he sends the blue bolts at you or the fire, deflect them back at him. This does alot of damage to him and can be frustrating. It works in all three rounds. Unless you are a pro, his attacks do too much damage to face him head on.
