Trap Generator

Shocking Grasp 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 releases the spell stored within the trapped object. The object is covered in arcane symbols and writing.

Effect: +5 to hit (or DC 10) against one target, Casts Shocking Grasp centered on the triggerer

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 10) cast on the eye disables the trap. An unsuccessful check triggers the trap. Casting dispel magic (DC 10) on the trap will cancel the stored spell.

Tar Pit

A passage is trapped with glowing runes which must be covered or toggled to display a specific password. If the wrong runes are showing then the trap is triggered, which opens the floor into a shallow pool of tar, sticking and slowing anyone caught in it. Some sort of dried substance is smeared on the walls and floors.

Effect: Targets all creatures within 20 ft., The floor opens into a shallow pool of tar, halving the speed of anyone in the area. The tar sticks to them, continuing to slow their movements until the tar is scraped off.

Trigger: runes, a surface is covered in glowing runes that can be touched or covered to form specific words, the correct word must be found to stop the trap.

Countermeasures: A successful DC 10 Intelligence (Arcana) check allows a character to figure out that the runes can be toggled or covered to make out different words. A successful dispel magic (DC 10) cast on the eye disables the trap. An unsuccessful check triggers the trap. Freezing the tar will cause anyone currently submerged to become restrained, but otherwise make it possible to walk full speed on top of a slippery surface.

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.
