Formian Venomcaster, Tactical
The formians on the moons of Vesk-5 developed this weapon to fire an envenomed dart. More expensive versions encase a fired dart in a monofilament casing. When such a dart strikes a target, it not only delivers the poison but shatters to constrain the target within the monofilament web.
