Summary::A technological oddity, it appears to be a heavy crossbow to which some manner of grapple and rope is attached. However, instead of a hook and normal rope, it contains a flat metal knob with a rubber cable, copper wire hidden within, and a battery placed inside the device itself. When impacting with metal surfaces, it can cling on with a powerful magnetic grip allowing people to scale up surfaces, yank away opponents weapons, or grab treasure from afar. Prerequisites: Craft Gadget or Craft Weaponsmithing, DC 25. Value 1000 gp; Weight 12 lbs.
