Nasty. Theyre pretty much the same as thiefly-types, but they like to use poison. Be prepared to cure it when you run into them. There is apparently a random bug in the game that will sometimes turn poison effects into Witches Pox and other diseases after you cast "Cure Poison". It's kind of an iffy thing, so be prepared to cure the disease after you cure the poison. The best tactic is to stand off and make pin cushions out of them or fry them with magic. Their goodies are about the same as the thieves.
