Spence Leffbruk's prod was an improvised weapon created by Spence Leffbruk after he and his son Dass Leffbruk were stranded on Gloam. It was lightweight and constructed out of a power pack and a salvaged head of a welder. It could give an electrical shock to a target when touched. Spence used it when a Gloam monster punched through a sheet of plating that they were using as a barricade and grabbed his son.
