Don't charge to the max when fighting the final boss. The instant the boss fight begins, charge to second stage glow (small glow, then medium glow), and blast him. If he already shoots the fireball, press X to squat and dodge the fireball and repeat until he can't use his fireball anymore. When he laughs, it's your chance to use 2nd stage blast on him repeatedly until he dies. He can't use fireballs since he's been disrupted by Alyssa's medium charge arrow, thus combo- ing him to death. But if he suddenly use the blood puddle attack, run and repeat. His dialogue will indicate if he's going to use it. Press R1 to use special arrow.
