Trap Generator

Beehive 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 opens a trapdoor in the ceiling and drops hives into the area. Angry wasps swarm and sting anyone and everyone. Bits of pulp are scattered about, and the ceiling is covered in stalactites or dense foliage.

Effect: Targets all creatures within 20 ft., hives drop from the ceiling, releasing an angry swarm of wasps that deal 9 (1d10) poison damage and DC 11 CON save or be poisoned for 1 hour.

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 15 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 11) cast on the eye disables the trap. An unsuccessful check triggers the trap. Filling the area with smoke will cause the wasps to become docile enough to cross without getting stung

Tar Pit

A denizen of the lair is hiding nearby out of sight watching for intruders to enter the trap's radius. When a hostile creature is spotted, the sentry pulls on a rope that 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: sentry, a sentry is hidden in a hole or around a corner with a rope that activates the trap when pulled.

Countermeasures: The sentry is a regular denizen of the dungeon, stealthed in a nearby hiding spot. A successful DC 15 Wisdom (Perception) check spots the sentry, and the sentry will activate the trap when they see enemies standing within range of it. Disabling, avoiding, or scaring off the sentry will render the trap harmless. 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.
