Looks like there are four mantraps in my game as well. Got jumped while talking to Erzebette, and scrambled a burning haze after just about surviving it's own lethal gas thing (while Erzebette was asking for a favour... like, I'm BUSY!). Killed it, got off a healing realm and was starting to load off cure poisons, when the second one turned up and turned my ravaged party into a pulp. Needless to say, the two mages were dead within seconds so there was no chance to toss a haze or a storm.
Loaded the game and went mantrap hunting... suffice to say I got my revenge
