So Regeneration 0 (lethal damage) would get turned off any time they take normal damage, but not non lethal damage, thus won't keep them immortal. It also doesn't actually heal them, since its value is 0. But it makes it where they can take an infinite amount of non lethal damage without it converting to lethal, and makes it where they can regrow lost body parts.
DR 0/epic similarly does not actually reduce damage, but due to how DR/epic works, allows them to count as an epic source for their natural weapons, thus overcoming DR/epic themself.
Is there anything else like this that I can bundle with these for a template?
