From Dungeons of Dredmor Wiki
Traps are found throughout the Dungeons of Dredmor, and can be disarmed, picked up, placed or crafted depending on the player's skills and skill levels. Mobs walking over traps will activate them, and they do not appear to attempt to avoid them, so placing traps then backing up is a good way to deal with an oncoming horde of monsters. Trap Sight Radius is the stat used to determine the distance at which you can spot and identify traps. Trap Affinity is the rating of your ability to avoid and disarm traps.
Your chance to disarm a trap is equal to 50+(5*([Trap Affinity]-[Trap Level])) expressed as a percent, however, at 50% you disarm traps automatically, and above 50%, you can pick up certain traps. If your Trap Affinity level is greater than the Trap Level, you can also see the trap icon on the ground, instead of the default trap outline.
Disarming a trap will earn the player 3+(3*trap level) experience points. The player must have a Trap Affinity skill greater than the trap level in order to pick the trap up (for those traps that can be moved).

 Table Notes
- Traps are treated as being casted by the player. This means that they can be made more deadly by using the player's Haywire, Magic Power and Melee Power (affects mundane Damage) stats.
- While descriptions indicate that traps may last for multiple hits, this is not true. Only the Robo Bolt Trigger, and all gargoyle traps will activate multiple times. The rest only activate once. The multi-shot traps cannot be picked up, but may be found in shops, allowing them to be purchased and placed normally. When one of these traps is placed, a corresponding wall launcher is placed on the nearest wall due north of the trap.
- Flying mobs, such as Battys and Djinns, do not trigger traps.
- To place a trap you've crafted or picked up drop it on any square next to you. Be aware that if a monster then moves onto that square as its move, the trap will activate before you have a chance to move away, potentially catching you in the area of effect.
- Traps and wall launchers can be moved with Psychokinetic Shove or other area affect knockback effects, however, they will still operate normally.
- Traps with wall launchers (such as the Gargoyle arrow trap) fire their projectiles in a straight line from the wall launcher, and may hit other intervening objects and mobs first.
- It is possible to buy some traps like the gargoyle acid bolt trap at brax's shop, however, they do not work.
- Several traps have been removed. These include several pirate cannons, dwarven mortars, and something called a "Necromantic Circle of Terrible Curses." The reason for removal is unknown, but cannons take up a place on the floor and can thus easily block passages.
- Designer notes on the Tentacular Infector say "good god, test this. It sounds horrible."
