Vorpal Nerf Gun (VNG)
Appearance: a heavily-etched and carved plastic toy resembling a six-round revolver, and shooting foam darts. The VNG operates perfectly well as a foam dart shooter, but something about the configuration of the gun and the carvings makes it peculiarly suitable for disrupting Outer Dark Entities (ODEs). In game terms, the VNG acts as a two point pool dedicated to situations involving Special Means of Dispatch for a particular ODE. Unfortunately, any use of the VNG itself damages the membrane. Thus, determining the cost/benefit of use versus nonuse is sufficiently tricky that trying to do so in the field is strictly forbidden.
