Source passage
Note: 30’ inside the entrance is a pit (B). There is a 3 in 6 chance that each person in the front rank will fall in unless they are probing ahead. There is a 1 in 6 chance that individuals in the second rank will also fall in, but only if they are close to the first rank and the character ahead has fallen in. The pit is 10’ deep, and those falling in will take 1-6 points of damage. The pit lid will close, and persons within cannot escape without aid from the outside. The noise will attract creatures from areas 1. and 2. Planks for crossing the pit are stored at #1., beyond.
