I am work right now, and I know if I forget to post now, I wont remember when I get home, so here it goes.
Anyone remember a list of undead from somewhere around 170-200? For the life of me, I cannot remember the article. But it detailed a few different types of undead, one was something to the effect of an
ACID ZOMBIE, 'its skin bleached white from the acid. Constantly moaning from pain. looks to be sweating. The sweat is actually acid."
QUICK SKELETON, this one could get in two attacks a round and moved really fast as is hasted, obviously.
Then there was one more skeleton. This one had brittle bones, and basically was meant to be destroyed, when it was destroyed, it released a form of stinking cloud from its bones.
I skimmed the list and did not see them. I had converted them for one of my games and it really threw the players for a loop with these guys.
(sorry, just found it now, it is was in 234. disregard)
