The Fleshborer contains a compact brood nest where Borer Beetles lay their eggs, which hatch and mature, sustained by the weapon for future use as ammunition. The weapon is connected directly with the creature using it and apparently runs off of the creature's bodily functions[Needs Citation].
The beetles move very little until the weapon is triggered by a massive electro-chemical shock which drives the beetle into sudden frenzied action . Using their powerful flea-like legs they launch themselves out of the weapon at tremendous speed. On striking they expend their life energy in a matter of seconds, boring frenziedly through the target's armour, flesh and bone. If however the beetle fails to find a target, or hits something that even in its frenzied state it cannot bore through, it quickly dies regardless.[1a]
