So, Castle Ravenloft
My PCs are on their way to the final confrontation. They've actually managed to amass a small army of Barovians they've befriended along the way, so I'm inclined to run the next session using some third party wargame-ish rules as they all march toward the castle.
Obviously Ravenloft has an insanely well defended position in itself, but my question is: what do you think Strahd would do to put obstacles in the way of an approaching mob?
Edit: I don't think I made myself clear. The mob isn't intended to get into the castle, just to help real with whatever nonsense Strahd throws in their way along the road.
