A Vr'gedian tranquilizer harpoon, which is also referred to as a tranq spear, functioned as a weapon designed to pacify a living being. The hunters known as Nokk and Winloss were equipped with this Vr'gedian tranquilizer harpoon, employing it during their hunt for the Shadowfang Beast on behalf of Doctor Chelli Aphra. Nokk attempted to utilize the harpoon on the creature, however, the weapon malfunctioned, causing only minor damage to the beast's hide.
