A Selection Of Fine Traps: The Unexpected Wine Tsunami
Early on in the dungeon, the characters will come to a very large room with 6 enormous vats of wine, a tasting area, and 3 ghosts who beg them to sit, rest, and taste the wine. Unfortunately, all the wine has turned to vinegar. Any PC who makes a face, gags, or refuses to drink, will send the ghosts into a rage. They will then start hacking at the vats with large axes. Smart PCs will run like hell, which may or may not save them from 300,000 gallons of vinegar that is about to flood this level and the one below it.
