Talk:Regeneration (3.5e Feat)
From D&D Wiki
 Fast Healing
So, is this like Fast Healing, except with a weakness to a particular energy type? I think that giving that much recovery might be a bit too much for a single feat, especially one without prerequisites. Look at the Fast Healing feat, for example. It requires Con 25, and it's an epic level feat. And even with those requirements in place, it only heals three points per round. I'd suggest taking a look at Minor Fast Healing for a lower-level version. It only restores 1 point per round, but even it has a fairly difficult prerequisite.
I realize that you threw in the energy susceptibility to help balance it, but fast healing isn't something to trifle with - it can be potentially game-changing with a skilled player, and it wouldn't be especially difficult to built a character who is resistant or even immune to the chosen energy type, negating the drawback altogether.
Also, if a feat must be taken at first level, stacking doesn't really make sense. True, a human PC could use the extra racial feat to take it twice, but then that PC would have fast healing 10, which would be ridiculous. For example, a greatsword does 2d6 damage (typically, about 7 damage per round); fast healing 10 would easily heal the PC back to full health every round, making him effectively invincible. Even the fast healing 5 gained from one level of the feat would be far too much to preserve balance within the game. Silverkin 21:12, 30 April 2011 (MDT)
