Heh. Jeff and Vinny got lucky. If they had been playing on expert, that Navas Nebula / Quake combo would have killed them. The boss casts Bewildering Fog on it's second turn which can surprisingly throw you for a loop. It happened to me twice. Even though I did kill him the first time I fought him, I didn't get the True Ending and my last save was before that dungeon. So I loaded up that save, went through the dungeon again, and died twice on him just because he psyched me out.
