S&W Bonus #2: Pit Traps!

Since everyone's having so much fun with S&W Appreciation Day, here are some charts to liven up your pit traps. Not terrifically S&W specific but hey, I like trap charts.

The tables below are intended to put some variety into the standard pit traps that one encounters from time to time in dungeons. Roll once on table 1 for the pit depth, once on table 2 for the dimensions, once on table 3 for what is covering the pit, and once on table 4 to determine any special features.

Table 1: Depth of Pit
01-105 feet (1d2 damage)
11-5010 feet (1d6 damage)
51-6515 feet (1d6 damage)
66-8020 feet (2d6 damage)
81-9025 feet (2d6 damage)
91-9930 feet (3d6 damage)
00Infinite (characters fall “forever”)

Table 2: Width and Length of Pit
01-102 feet by 2 feet (victims may become stuck)
11-305 feet by 5 feet
31-5010 feet by 5 feet
51-8010 feet by 10 feet
81-9010 feet by 20 feet
91-0010 feet by 30 feet

Table 3: Trap Covering
01-10Open pit
11-30Trap Door, Stays Open
31-40Trap Door, Resets after 1d6 turns
41-50Wood (only triggered if more than 200 lbs weight is above pit)
51-60Glass (shatters if more than 100 lbs weight is above pit)
61-70Loose stone (crumbles to reveal pit beneath)
71-80Sliding section of stone (moves away; resets itself after 1d6 turns)
81-90Cloth covering (canvas or other fabric; goes into the pit first)
91-95Illusion of actual floor (can be disbelieved if pole or other object goes through)
96-00Solid stone; magically disintegrated if more than 200 lbs above pit.

Table 4: Special Features
01-35Bare Floor
36-45Spikes, Wooden (add 1d4 damage)

  1. Nice! Can't beat a snakepit.

    Another special feature might be a tunnel or secret door part way down or at the bottom of the pit. Some monsters that use the pit as a trap may actually live down there. Or if it's deep it could be a way to get to the remains.

    1. Yeah. I didn't do traps leading to the next level because that should be deliberate dungeon design. This is for sprucing up an "X" on the map.

    2. Rather than a connection to a lower level, I was actually referring to a compartment/room/tunnel/ledge (secret or otherwise) that is self-contained within the pit, possibly home to a monster or treasure or other secret.

  2. One of my favorites is a pit trap at the bottom of a pit trap...
