Rune of Fear

This trap has a cover constructed from material identical to the floor around it that activates a rune of power, fearing the target.

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

Trigger: cover, activates when a creature steps on the false floor and drops into the trap.

Countermeasures: Once the trap is detected with a successful DC 20 Wisdom (Perception) check, an iron spike or similar object can be wedged between the cover and the surrounding floor in such a way as to prevent the cover from opening, thereby making it safe to cross. The cover can also be magically held shut using the arcane lock spell or similar magic.

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

Falling Gate

A denizen of the lair is hiding nearby out of sight watching for intruders to enter the trap's radius. When a hostile creature is spotted, the sentry pulls on a rope that makes an iron gate drop from the ceiling some distance behind, blocking the exit.

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: sentry, a sentry is hidden in a hole or around a corner with a rope that activates the trap when pulled.

Countermeasures: The sentry is a regular denizen of the dungeon, stealthed in a nearby hiding spot. A successful DC 20 Wisdom (Perception) check spots the sentry, and the sentry will activate the trap when they see enemies standing within range of it. Disabling, avoiding, or scaring off the sentry will render the trap harmless.

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.
