Weapon Traps: A Weapon trap contains a Weapon on a spring mounted mechanism. This must be mounted on a large or heavy object, such as in a crate or a trunk, or onto a door. Once armed, a Weapon trap cannot be moved.
OOG, the trap merely has to have a standard trap trigger (a light or noisemaker) and a Weapon with a valid item tag must be attached. There must be a clearly marked “pivot point” for whichever Weapon physrep is being used. When the trap goes off, a Pause Game is called and the Weapon is rotated around the pivot point. Anyone touched by the Weapon is affected as though they had been struck by a Weapon blow of the stated amount and type. Note that the Weapon does not actually need to be swung or be on a spring for safety reasons. The mounted Weapon may be any standard approved Weapon.
Weapon traps are not destroyed when set off and may be re-armed by anyone with the appropriate Skill without paying the cost to rebuild them.
Weapon coatings may be applied to the Weapon used in a Weapon trap. These coatings are consumed as normal when the trap is set off and must be re-applied when the trap is rearmed.
Weapon Traps may not be blocked by a Weapon or Shield, but any pertinent defense against a Weapon qualifier attack or physically delivered Poison (if the Weapon is coated) can be used, like Evade, Parry, Dodge, or the Weapon Shield spell.
