Acid Turret

A door or chest is rigged to activate when opened, which causes acid to spray from a hidden nozzle. The walls are covered in foliage or perforated stone.

Effect: Targets all creatures within a 20 ft. cone, DC 13 save or take 61 (10d10) acid damage for 4 (1d4) rounds

Trigger: door, activates when a door or chest is opened.

Countermeasures: Spotting the attached wire is a DC 10 Wisdom (Perception) check. A successful DC 15 Dexterity check using thieves' tools breaks the wire attached to the door harmlessly. A character without thieves' tools can attempt this check with disadvantage using any edged weapon or edged tool. On a failed check, the trap triggers.

Attempting to destroy the trap causes the pipes to rupture and spray acid over the area.

Poison Gas Trap

A stuck door must be broken down to pass but breaking down the door causes the PC to stumble into the trap, which causes pipes to open and release poisonous gas. The area has a weird smell and exposed pipes.

Effect: Targets all creatures within a 10 ft. square area, DC 13 CON save or take 65 (10d10) poison damage

Trigger: stuck door, a stuck door that must be broken down to pass.

Countermeasures: Destroying or circumventing the door in some way other than smashing it down avoids the trap.

Plugging all the pipes with cloth or other material will prevent the gas from escaping.

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.
