Trap Generator

Boiling Tar-Filled Room

A pedestal with a button sits in the center of the area. Creatures that push the button trigger the trap which makes the doors slam shut and the area gradually fill with the caustic liquid. There's little puddles of the liquid about the area.

Effect: Initiative +4, doors seal shut and room fills up with 2 ft. of liquid per turn, dealing 11 (2d10) damage. After 1+(CON bonus) minutes (min 1) of holding breath your HP drops to 0.

Trigger: button, a button activates the trap when pushed.

Countermeasures: A successful DC 15 Dexterity check using thieves' tools disarms the trap, removing the trigger from the button and allowing it to be pressed as many times as you want. Unsuccessfully attempting to modify the button triggers the trap. Alternatively a creature may be able to build up the incredible willpower necessary to resist the temptation to push it. The doors can be opened with a DC 15 Dexterity check using thieves' tools.

Push Trap

A door is trapped and either has buttons or holes to fit a weapon that produce a note, or requires an instrument to be played before it. If the wrong tune is played before opening the door then the trap is triggered, which causes the wall along a narrow ledge to push out, forcing intruders off the ledge and into the pit below. There's a narrow ledge overlooking a hazard.

Effect: Targets all creatures within a 10 ft. square area, the wall pushes out along a narrow ledge, pushing targets into the pit below which deals 9 (2d10) damage.

Trigger: musical tune, a musical tune can be heard elsewhere in the dungeon, and the tune must be repeated at a door or similar to disable the trap.

Countermeasures: A successful DC 10 Intelligence (Investigation) check allows a character to figure out that the lock requires a specific tune. A successful DC 15 Performance check can recall and play the tune if the character heard it. A successful dispel magic (DC 14) cast on the eye disables the trap. An unsuccessful check triggers the trap.

Destroying Traps

Traps can be damaged and destroyed, sometimes to good or bad effect. Pipes containing fire or poison will rupture and spray over the area, while mechanisms can be rendered inoperable with enough force. Determine the HP and AC of your traps based on the tables below. Sometimes a fragile trap is more dangerous than a resilient one if destroying it will fill the corridor with acid.
