Strange beasties, ettercaps. And none so strange as the variant ones presented here.
Sometimes you happen to want a monster that's not straight out of the book. Maybe your players know the standard monster books backwards (I recently had to ask one player when her character had ever encountered a cloaker, she seemed to know so much about them!), sometimes something a bit out of the ordinary fits your plot better.
So, here are 3 variations on those weird spiderish beasties... a feral ettercap, a webspinner ettercap and a spider lord one.
I think I like the webspinner one best. It can spin a selection of different webs depending on the situation and its needs... really neat. On the rare occasions I come out from behind the screen and play, I enjoy studying the unusual amongst monsters, indeed I've been known to play naturalist characters who seek them out, sketch them and write them up!
