This little, twisty module sets out with a rather funny evil idea and a maybe not so funny for the consumer magic potion. Can’t get more classic than a city sewer crawl.
I don’t mind the rather deadliness of the potion. What I don’t like is the open end in the sewers, where players don’t get a clear signal that nothings to be had down there and the DM has do come up with content till they give up.
