Heat Metal Trap

A door or chest is rigged to activate when opened, which releases the spell stored within the trapped object.

Effect: +10 to hit against one target, Casts Heat Metal centered on the trigger with DC 18 (if relevant)

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

Countermeasures: Spotting the attached wire is a DC 15 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.

Casting dispel magic (DC 15) on the trap will cancel the stored spell.

Push Trap

An area is warded with a detect magic spell. When magic is detected within the spell's radius the trap is triggered 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 24 (4d10) damage.

Trigger: magic detection, activates when magic is detected in an area.

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 area. A successful dispel magic (DC 18) cast on the area destroys 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.
