I've run into this room with two gargoyles. I shoot an arrow at one of them (using Duke Patrick's Combat Archery), get 3x damage for sneak attack, and it doesn't even dent it! I tried a silver arrow, same deal. Then it comes over and slaughters me.
Any tips for dealing with gargoyles? There must be some weakness I'm missing. I'd get them slaughtered by a trap but there don't seem to be any in this dungeon.
