Dual Hook

The Dual Hook is an upgraded version of the Grappling Hook. It is one of the items that a Mimic can drop. With it you can shoot two hooks, one at a time, or both in quick succession. When one hook is already attached, firing and attaching the secondary hook will cause the initial hook to detach. One hook has a red light, while the other has a blue light, both producing dim illumination. The blue hook will always be shot first, unless it is attached to a wall already. There can be two moving grapples at the same time. This can be used to re-shoot a grapple to prevent fall damage if the first misses. It also produces light, refueling the Mythril armor and higher's shine (making cave exploring much easier).

Because the Ivy Whip can't shoot more than one vine at a time, having three hooks has little noticeable benefit over the Dual Hook. However, only the Ivy Whip can suspend you between two walls, especially useful when mining close to lava, Meteorite, Hellstone, or Spikes.

The Dual Hook's range is 29 blocks, slightly longer than the Ivy Whip.
