Hey WD dude! 
Its smaller than splitting it up, but its not smaller than simply making it Su - which was my initial solution.
Nevertheless the only difference seems to be that of gravity, which could actually be accounted for in creatures if they have sufficient strength. In fact I anticipate Giants (with listed strength scores) would probably be feasible.
If holy energy is natural then there is no such thing as magic in D&D.
If it doesn't occur naturally in the Prime Material Plane then its unnatural. No animal has a supernatural attack for that very reason.
So if the character was immune to Con damage you go along with the idea that damage should be irrelevant?
Its far to easy to get regeneration and get rid of the weaknesses.
Variety is the spice of life.

WarDragon said:I disagree; in RL, things are made of 100+ odd elements; in D&D, they're made of only four, plus two fundamental energies. In RL cold, darkness, and death are the absence of heat, light, and life, respectively; in D&D, they are forces unto themselves, which oppose and mutually annihilate heat, light, and life.

WarDragon said:Indeed I am not, sir. Holy and unholy energy are no more unnatural in the D&D setting than electromagnetic energy is in our universe.

WarDragon said:Er... Regeneration doesn't fix ability damage, and if your Constitution is reduced to 0, you're dead. It doesn't get much more "lasting forever" than that, as long as the supernova deals enough Con damage to kill flat-out; even if it doesn't, a regenerater won't heal that damage any faster than a normal human. As for disintegration, I am of the opinion that it should always be counted as lethal damage, or in this case, a death effect.
So if the character was immune to Con damage you go along with the idea that damage should be irrelevant?
WarDragon said:Which is why Regeneration specifies that you can't have it if you don't have a Con score. Undead and constructs can have fast healing, with special clauses that let them reattach limbs; again, Occam's Razor.
Its far to easy to get regeneration and get rid of the weaknesses.
WarDragon said:Works for me. I can't really say why (because I don't know), but I just find most anime to be inherently annoying... same as psionics in a fantasy setting.
