Weapon Type: Any
For those who want to use lethal weapons in nonlethal ways, an inertial dampener is the tool of choice. You can activate or deactivate an inertial dampener as a swift action. While the dampener is active, it creates a field around the weapon or its ammunition that causes the weapon to deal nonlethal damage in place of its regular damage.
