Haunted is an element that can be added to any mechanical trap. Haunted allows the trap to automatically reset, even if the reset element was not built into the trap. It also allows the trap to maintain function even in disrepair, with the broken condition, or worn out from age.
Most haunted traps are created when the crafter of the trap dies in the area the trap is guarding, and their spirit remains to keep the traps going. Only the most mad and covetous of souls stay behind for this.
The Perception DC for telling if a trap is haunted is 25, as it allows the character to detect the subtle impossibilities in the trap's mechanical construction and function.
Haunted traps can be damaged and destroyed with positive energy.
