Chain Flail

An enemy in disguise asks for help and leads the PCs into the trap and triggers it, which causes large flails to swing. The ceiling is covered in holes and mechanisms.

Effect: Initiative +3, 1 attack per round, +6 to hit against all targets within 5 ft., 16 (2d10) bludgeoning damage and knocked prone

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

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

Push Trap

This trap has a cover constructed from material identical to the floor around it that 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 12 (2d10) damage.

Trigger: false floor, activates when a creature steps on the false floor and drops into the trap.

Countermeasures: Once the trap is detected with a successful DC 20 Wisdom (Perception) check, an iron spike or similar object can be wedged between the cover and the surrounding floor in such a way as to prevent the cover from opening, thereby making it safe to cross. The cover can also be magically held shut using the arcane lock spell or similar magic.

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.
