Trap Generator


Push Trap

An enemy in disguise attempts to direct the PCs into the trap by lying about where they need to go and triggers the trap when the PCs get close, which causes the wall along a narrow ledge to push out, forcing intruders off the ledge and into the pit below.

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 50 (10d10) damage.

Trigger: enemy, an enemy in disguise directs the PCs into the trap.

Countermeasures: A successful DC 10 Insight check can tell that the enemy is lying. A successful DC 20 Dexterity check using thieves' tools disarms the trap.

Spring Trap

A doorknob is trapped to activate when it's turned the wrong way, which triggers a massive coil to spring up and launch the target.

Effect: One target, a massive spring coil flings the target into a wall or other trap/hazard. If catapulted into a wall, DC 14 DEX save or take 53 (10d10) damage

Trigger: doorknob, activates when the doorknob is turned the wrong way.

Countermeasures: A successful DC 10 Intelligence (Investigation) check allows a character to deduce the trap's presence from alterations made to the mechanism to accommodate the trigger. A successful DC 20 Dexterity check using thieves' tools disarms the trap, removing the trigger from the door. Unsuccessfully attempting to pick the door 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.
