So the only advice I can give is be a higher level. The closer to Level 95, the better. What you need to do is equip a fire weapon that can constantly hit 600+. My weapon of choice is Arza Bogoda, Fire Element. While using the PA: Renzan Seidan-ga. It does the job fairly well. If you are a force, you can switch to high percentage fire melee weapons, or keep using a high level Foie spell over and over and over. Protransers and Gunners should use Fire traps in combination with Fire weapons. Once you have these weapons, be sure to lock onto him, and try not to use Photon Arts that will blow him away too far from you. You need to hit him very quickly very hard in the shortest amount of time possible. If you keep it up he will die and disappear with a present for you, then magically come back to life in the cutscene!
