Does this go here? I'm not sure but here goes.

Inside Sin you have to fight Seymour Omnis, now I've already played through this game once but I have yet to beat him without being cheeky and absorbing his attacks using various aeons, who then do most of the legwork and kill him. Does anyone have any other strategies? I've lookled through gamefaqs.com and everyone tells me to do the same thing. I want some real satisfaction of having killed him myself, even though he's nowhere near as hard as is Flux incarnation at Gagazet. I have pretty much all of the Celestial weapons and I've beaten Omega Weapon so I'm plenty far enough round the sphere grid.
