Word of Radiance Trap

A door or chest is rigged to activate when opened, which releases the spell stored within the trapped object. The object is covered in arcane symbols and writing.

Effect: +4 to hit (or DC 12) against one target, Casts Word of Radiance centered on the triggerer

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 10 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 12) on the trap will cancel the stored spell.

Bear Trap

This trap activates when a ruby or other valuable item is pried from a statue or other surface, that causes a set of iron jaws to spring shut, clamping down on a creature's leg. The trap is spiked in the ground, leaving the victim immobilized. The floor is covered in a dense layer of leaves or other loose debris to camouflage the trap.

Effect: +4 to hit (or DC 12) against one target, the jaws of the trap clamp shut, dealing 9 (1d10) piercing damage on a hit and the target is restrained until the trap is opened with a successful DC 12 STR check.

Trigger: removal trigger, activates when a gem or other valuable item is removed.

Countermeasures: A successful DC 10 Intelligence (Investigation) check allows a character to find a wire attached to the item which triggers the trap when pulled. A successful DC 10 Dexterity check using thieves' tools disables the trip wire 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. The bear trap can be spotted with a DC 10 Wisdom (Perception) check and a DC 10 Dexterity check made with thieves' tools disables it.

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.
