Shocking Grasp Trap

A stuck door must be broken down to pass but breaking down the door causes the PC to stumble into the trap, which releases the spell stored within the trapped object. The object is covered in arcane symbols and writing.

Effect: +3 to hit against one target, Casts Shocking Grasp centered on the trigger with DC 11 (if relevant)

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.

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

Arrow Trap

This trap is activated when an intruder steps on one of the alternating hidden pressure plates that causes arrows to fire from small openings in the wall. The room contains a porous wall and broken arrows.

Effect: +3 to hit against one target, 1 (1d10) piercing damage

Trigger: alternate tiles, activates when 20 or more pounds are placed on alternating floor tiles.

Countermeasures: A successful DC 15 Intelligence (Investigation) check will deduce that the alternating floor tiles are pressure plates, and wedging an iron spike or other object under the pressure plates prevents the trap from activating. Alternatively, step on the safe floor tiles in alternating order.

Plugging the arrow holes with cloth or other material will prevent them from firing.

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.
