Thanks, guys -- this is interesting. I've looked at MM I-IV plus the FF and couldn't find an exception.I know of at least one...the jaebrin in MMV.
True enough! I think a manes from FC1 might have DR 1, but I'd have to check...As always, thanks for the suggestions. I ended up going with DR 1/cold iron, to keep the svart distinctive from kobolds and goblins but not too much so. And besides, I don't think I've seen many monsters with DR 1/anything. Why should barbarians have all the fun?
