Skin = uncommon undead.
No no, I meant like the type of undead. The animated corpses that necros bring back are (AFAIK) supposed to resemble the stereotypical, mindless walking corpses you usually associate with zombies. I don't feel that this sort of reanimated creature should have any sort of special ability beyond mindless attacking the living. I like the concept, I just feel it should be reserved for other kinds of undead/unique creatures.
I agree with Witty. This isn't a bad idea, but I think I would associate it with night trolls, or similar intelligent foes, rather than the standard animated dead.
Doesn't happen much due to the kinda deaths you get with undead, but would be a great feature if it happened much. Maybe we should be able to wear people's skin as a disguise?
I don't think I've ever seen anyone wearing someone else's skin to confirm it, but somehow I don't think that would make for a convincing disguise up close.
Against undead or animals perhaps?
What I understand of how the undead [OPPOSED_TO_LIFE] token works seems to indicate that a disguise of this sort would not be effective.
It might work on animals. Supposedly (I'm not sure how reliable my source was on this, so take this with a grain of salt) when deer smell wolves and carrion coming from the same direction, they assume the wolves are scavenging the kill, and therefore not stalking them, so they become less alert. A human hunter (or dwarf, or whatever else) might be able to exploit this, but the disguise is against scent, not vision.
