From publisher blurb:
Hard to Kill is a collection of thirty new feats designed to provide players of both types of characters with ways to ensure the success of their characters. In addition to a handful of feats for adventurers of the first type, the bulk of the feats presented here are for the second type. Called “Survivor Feats,” these feats offer a wide range of new abilities to characters, but these abilities come at a price. To take a Survivor Feat, a character must have in his past suffered a setback of some sort, in some cases a very significant one. It is said “that which does not kill me makes me stronger” and that is certainly the basis for Survivor Feats – although being killed is in fact the prerequisite for several of these feats!
