Trap Generator

Double Pit

This trap is activated when a creature touches its surface, which causes the creature to fall through the floor into the hidden pit below. The pits are situated in a row so attempting to jump over the first pit will cause the creature to land in the second. The floor is covered in a dense layer of leaves or other loose debris to camouflage the trap.

Effect: Targets all creatures within a 10 ft. square area when stepped on, two hidden pits in a row, jumping over one causes the creature to land on the second. DC 15 DEX save or take 27 (4d10) falling damage

Trigger: touch trigger, activates when surface is touched by a creature.

Countermeasures: A spell or other effect that can sense the presence of magic, such as detect magic, reveals an aura of divination magic around the surface. A successful dispel magic (DC 15) cast on the surface destroys the trap. The pits can be bridged with a plank or sidled via a thin ledge next to the wall. Doing so requires a successful Dexterity (Acrobatics) check.

Burning Snare

An enemy in disguise asks for help and triggers the trap when the PCs get close, which causes a snare to wrap around their leg and lift them into the air. The floor is covered in a dense layer of leaves or other loose debris to camouflage the trap.

Effect: Targets all creatures within a 10 ft. square area, DC 15 DEX save or become restrained and lifted high into the air as the rope catches on fire, dealing 5 (2d4) fire damage per turn. The fire will eventually burn through the rope, causing them to fall and take 15 (4d6) bludgeoning damage.

Trigger: enemy, an enemy in disguise asks for help.

Countermeasures: A successful DC 10 Insight check can tell that the enemy is lying. A successful DC 15 Dexterity check using thieves' tools disarms the trap. The snare can be cut, but will cause the victim to fall if it's already been triggered.

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.
