Swarm

A weapon with this special property is virtually indistinguishable from Swarm technology and requires a special Swarm battery to use efficiently. The weapon can use other batteries, but usage doubles when doing so. In addition to the energy drawback, a Swarm weapon attracts the attention of nearby Swarm creatures. They can sense such a weapon as if using blindsense with a range of 30 feet. Swarm components have been observed fixating on wielders of this technology during battle, with little else to explain such a violent focus. If the Swarm wins the conflict, the surviving components destroy these weapons.
