This is an entry for a contest – tell us about one of your traps…!
Way back in the day, I decided to spring a trap that was, quite simply, a pun. The PCs of my AD&D campaign were exploring a basic evil wizard’s tower, filled with all sorts of monsters and traps. At one point, they entered a room that appeared to be a normal study. There were heavily-laden bookshelves on the walls, overstuffed couches facing a coffee table and fireplace, lamps on end tables, and a very large, ornately carved mahogany desk.
They didn’t realize until they had their hands in its drawers that the desk was actually a Large-sized wooden golem, animated by the wizard to protect his books.
And that’s the story of how my players encountered a Wandering Monster Table.
