The Climbing Rope is a one-shot grappling hook that, while hanging, allows the player to ascend or descend the rope (to an extent). Very useful for safely lowering into large caves.
Attempting to jump or re-launch the rope will consume the item, however switching to another item will not. Therefore, a Climbing Rope can be used multiple times.(Verify?)
Not to be confused with Rope, which doesn't actually do anything.
