Burning Snare

A phrase etched on a wall is enchanted to trigger when read aloud, which causes a snare to wrap around their leg and lift them into the air.

Effect: Targets all creatures within a 10 ft. square area, DC 20 DEX save or become restrained and lifted high into the air as the rope catches on fire, dealing 6 (2d4) fire damage per turn. The fire will eventually burn through the rope, causing them to fall and take 15 (4d6) bludgeoning damage.

Trigger: forbidden phrase, activates when etched runes are read aloud.

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 phrase. A successful dispel magic (DC 20) cast on the phrase destroys the trap.

The snare can be cut, but will cause the victim to fall if it's already been triggered.

Box of Brown Mold

An idol or other valuable object's weight is keeping a pressure plate depressed just the right amount. If the pressure plate raises or lowers it opens a box containing dangerous mold that immediately attacks.

Effect: Targets all creatures within 5 ft., DC 20 CON save or take 17 (4d10) poison damage and be poisoned for 2 hours

Trigger: pedestal, activates when an idol or other object is removed from a pedestal.

Countermeasures: A successful DC 20 Intelligence (Investigation) check allows a character to deduce the trap's presence. Placing an object of equal weight on the pedestal prevents the trap from triggering. A successful DC 10 Dexterity (Sleight of Hand) check makes the switch without causing the weight on the pedestal to change. Unsuccessfully attempting the swap triggers the trap.

Cold damage can destroy the mold, rendering the trap harmless.

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.
