Points to Aleph_null1! I do agree that stoned mantraps are infinitely useful. For a minute there, I even thought that Stackman had graced us with his presence
And Jon, you do have to thaw them out before you can get the XP. All that attacking stoned monsters gets you is damaged and broken weapons...
Unless.... they weren't stoned via the magical spell, but instead imbibed too much Boogre Brew, in which case they wouldn't be able to react very well, would they? I just wouldn't want to be the waiter for that table...
