"Well, evil creatures of all sorts will be inclined to negotiate with us more carefully when they see it, but other than that I don't think it will have much effect."  Wendy speculated.  "I doubt Acererak would have much of a reason to even give a thought to Doresain, since he's a lich and Doresain is King of Ghouls.  At most, it would probably just be something that would give him pause, maybe give us an opening to negotiate if things start off on the wrong foot.  I certainly don't think he'd set any traps specifically for followers of Doresain.  So far, he's preferred to be a little more indiscriminate than that."
