ARC-77 deploying an electrified grappling hook against Durge. The electrified grappling hook, also referred to as an electro grappling hook, was a wrist-mounted device that launched an electrified hook. The system featured a button on the wrist mount for firing the hook, and a separate button to deliver a potent electrical charge through it.
During the assault on Muunilinst, Captain Fordo employed this weapon against Durge. Fordo successfully struck Durge in the forehead, administering a powerful electric shock. Despite Durge severing the connection, which resulted in Fordo being thrown backward and exposed, General Kenobi harnessed The Force to escape Durge's grasp and briefly subdue him.
