Megadungeon: Random Trap Disarming Table.


Occasionally, I find myself at a bit of a loss to describe how the players need to disarm a trap they've found, or how they must open a secret door, so I put this together to give those situations a little more flavor. For instance, rather than stating "You disarm the trap", its a bit more interesting to make them clean out a series of small metal gears concealed beneath a festering compost pile.

Use this table to determine how a trap has to be disarmed, regardless of whether you use a percentage roll or S&W-style trapfinding. Alternately, with little modification, the table can be used to determine how a secret door is opened.

Roll d100:

1. Rusty chains snake across the ceiling, disappearing into holes on either wall.
2. Three brass floor plates, nearly invisible beneath the dust and detritus.
3. An eroded bas-relief of a grinning Pan-like figure, its fingers appear to be moveable.
4. A shallow gutter runs along the far wall, with a loose brick restricting the flow of water through it.
5. What appears to be a keyhole is discover behind a loose stone.
6. A rusted and jammed lever is found beneath a discarded pile of clothing.
7. A row of fake-emerald buttons on the wall, covered in cobwebs.
8. Three stones are arranged in a circle on a lead pressure plate.
9. A painting of an octopus is found in a far corner, three of its arms appear depressible.
10. A foot-long strip of iron is set into the ceiling, with a small magnet at one end.
11. A small wooden door opens to a panel filled with strange metal gears.
12. Three tiny brass levers in a hand-sized hole in the floor.
13. A moldy rope lies on the floor, leading to a pulley lost in the shadows of the ceiling.
14. Four keyhole sized openings along the bottom of a door.
15. A magical rune glows red when touched.
16. A small statuette of an elephant lies beside a small stone pedestal.
17. A loose block in the ceiling appears to be hooked to a chain above.
18. Three counterweights hang on ropes just inside the door.
19. A bas-relief of a demonic face has depressible eyes.
20. A camouflaged metal door on one wall conceals a copper lever.
21. A magic mouth appears and demands a password.
22. Magic runes spell out “Erase Me” with Read Magic.
23. A statue of a wizened sage has moveable arms.
24. An abandoned bottle contains a key matching a concealed hole in the wall.
25. A loose brick has fallen out of the wall and must be replaced.
26. A ghostly apparition appears and demands a song be sung to him.
27. A pulley disarms the trap, but the rope is missing.
28. A empty gourd hangs from a hook on the wall and must be filled with water.
29. Three couplets of an old poem are scrawled on the wall; the missing couplet must be recited aloud.
30. Two orcs are painted on the floor; erasing one disarms, erasing the other sets off trap again.
31. The trap is not disarm-able, but a detailed schematic of the next trap is drawn in chalk upon the floor.
32. Four loose bricks must be straitened.
33. Water must be poured upon a leather strap hanging over the door to loosen it.
34. A ceramic cap over the disarming panel must be broken open.
35. A filthy wax seal over the panel must be melted away.
36. A magic mouth appears and demands to know the meaning of life.
37. Five pewter runes in the ceiling must be depressed in order.
38. A console of brass buttons is a decoy; the real trap release is hidden beneath.
39. Detect Magic must be cast to reveal the invisible lever.
40. A statuette of a dog must be broken open to reveal a key.
41. A silver floor panel (20gp value) covers a stone lever crawling with centipedes.
42. A stone chest must be opened to a precise degree.
43. An empty hourglass must be filled with sand and turned upside down.
44. Three wall levers: two set off the trap again, one disarms.
45. A candle in a wall sconce must be burned down to disarm.
46. A wall sconce must be turned to a right angle.
47. A chandelier must be pulled down to floor, revolved 180 degrees, and sent back up again.
48. Every candle on a seventeen candle-candelabra must be lit; seven candles are missing.

51. An imp appears and demands payment to disarm the trap.
52. A globe hangs from the ceiling; Light must be cast upon it.
53. A hollow needle emerges from the wall; pricking a finger upon it disarms trap.
54. A ceramic alligator statue with gaping maw: will close maw if fed meat and disarm trap.
55. A snake-filled pit contains the release lever.
56. A small ochre jelly (1+1HD) must be coerced off the pressure plate it rests upon.

  2. While that table certainly is cool, I am surprised that one doesn't know how one's own traps function.
    --What prompted the inclusion of a trap if its design wasn't known beforehand?

  3. Thanks for both this and the previous post. The whole sandbox/one-page manifesto/random tables thing is incredibly inspiring - this is really very useful stuff.

  4. @Timeshadows - Great question! There are plenty of random trap tables to tell you what trap is in a room (see OSRIC, 1E DMG, etc), but not much on how exactly to disarm that old spiked pit or crossbow trap once you've found them. Not to mention how to open that little sideways "S" on the map.

    With Megadungeons especially, custom designing every little feature for literally hundreds of rooms can be creatively exausting, so I find random tables really help keep the brain juices flowing. Just like old-school rules, your result on a random table isn't always meant to be adhered to rigidly, but rather shaped as desired. :)

  6. This table provides an actual solution to what has always been an issue in my games; how can I expect players to cleverly thwart my traps if I just rolled them and have no mechanism in mind?
    This is really, really cool. Same goes for your dungeon doors table. Really inspiring, useful stuff. Please tell me you have more tables planned!

  8. Man, this is great. I'm one of those people that can write encounters while blindfolded with one hand tied behind my back, but ask me to come up with a trap and explain how it works and I'll just stare at you. Totally swiped. You should submit this to Fight On! or Knockspell or something like that.
