Just because a monster is lame doesn't mean they can't do some damage. I've never run into these creatures but when I was up at five in the morning trying to think of what Xionus, Flynn and Garzzle were fighting this creeped up out of the subconscious.
What's nice about using a monster that seems stupid is players will drop their guard. Maybe hold on to that holy handgrenade until it's too late.
Much like elves...
haha good point about elves.
