I should mention that Ragnar's got a bionic arm in his trophy rack now too. Ripped it off the cleric we were hunting down. (Who, by the way, wasn't a cleric at all, but an artificer dabbling in human artificy ala Dr. Frankenstein or the
Boys from Brazil) This happened after the party got spanked by a chimera he had made from various animals. Apparently the cleric/artificer had an artificial arm, similar to a warforged's.
