Rune of Fear

An area is warded with a detect magic spell. When magic is detected within the spell's radius the trap is triggered which activates a rune of power, fearing the target. The surface is covered in runes.

Effect: Targets all creatures within 10 ft., DC 10 WIS save or become frightened for 3 (1d4) rounds

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 10) cast on the area destroys the trap.

Casting dispel magic (DC 10) will dispel the runes in the symbol.

Falling Gate

This trap is activated when an intruder steps on a hidden pressure plate that makes an iron gate drop from the ceiling some distance behind, blocking the exit. The floor is cracked and damaged.

Effect: Targets all creatures within a 10 ft. square area, An iron gate drops from the ceiling some distance behind the trigger, blocking the exit. Any target underneath the gate makes a DC 10 DEX save or takes 7 (2d10) bludgeoning damage.

Trigger: pressure plate, activates when 20 or more pounds are placed on it.

Countermeasures: A successful DC 20 Wisdom (Perception) check will spot the pressure plate, and wedging an iron spike or other object under the pressure plate prevents the trap from activating.

The gate can be destroyed with an AC and HP based on its material (see destroying traps below).

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.
