ARC-77 employing an electrified grappling hook against Durge. The electrified grappling hook, alternatively known as an electro grappling hook, was a hook, electrified, and wrist-mounted, deployed via a single button located on the wrist-mounted mechanism. Subsequently, a second button activated a potent electrical surge within the hook.
During the assault on Muunilinst, Captain Fordo utilized this device against Durge. Fordo successfully struck Durge in the forehead, delivering a substantial electric shock. Despite Durge severing the connection, which caused Fordo to be thrown backward and become exposed, General Kenobi employed The Force to escape Durge's grasp and momentarily subdue him.
