Rapid Metabolism seems a bit of a waste with that regeneration. Same with Epic Toughness, sort of. I suppose Perfect Health is not quite as redundant, but I'm not fond of it here, either. I suppose Mental Resistance is ok, but I don't see the rationale either.
Dang it, I just didn't think of its regeneration when I wrote Rapid Metabolism. What was I thinking!
I like Perfect Health for it, and don't mind Epic Toughness. The Mental Resistance doesn't do much for me, but I was having trouble thinking of anything better.
Ability Focus (Engulfing Maw), Alertness, Blind-Fight, Endurance, Diehard, Improved Initiative, Iron Will, Lightning Reflexes, Epic Reflexes, Epic Will, Superior Initiative ??
I don't like the initiative boosters. It's described as being basically non-responsive unless it's poked from the inside with a sharp stick, so why would it have fast initiative?
The Alertness doesn't feel quite right, for similar reasons.
Come to think of it, shouldn't the same complaint apply to Epic Reflexes and Lightning Reflexes?
How about cutting the Initiative feats and giving it Epic Fortitude and Perfect Health?
