I played Castle Daerion yesterday. It was the first scenario after the Introduction with me being the OL. In the first encounter I chose the Shadow Dragons as an open group and I have to admit it wasn't fun at all. It took four rounds of boring, senseless beating until the heroes managed to kill the first of the two dragons. I won easily. Two defence dice and the "Shadow" ability seem a bit too hard for young heroes. Is there any trick combination or whatever which work against "Shadow Dragons"?
