How the hell do you beat this bastard?
Lightning - Com
Snow - Sen
Hope - Med
My two most used paradigms are:
Lightning - Med Snow - Sen Hope - Med
Lightning - Com Snow - Rav Hope - Rav
I usually switch between those and one where Hope is a synergist to buff up the party but I usually end up dying when his frickin' Progenitor attack or whatever kills me in one hit.
I can take Merciless Judgement just fine and heal up really quick with Med-Med-Sen after that.
What's a quicker way of dealing him damage as he casts Doom on you at some point as well.
