Grappling Hook

The Grappling hook is an extremely useful tool, used to grab on to surfaces and is created with 3 chains and 1 hook. It can be used on all surfaces and is helpful for navigating caves and building homes. However, it does have a limited range.

You may use other tools at the same time you are grappled onto a wall, but note, destroying the block you are hooked to will break the connection, causing you to let go and fall. You will also fall if you stay grappled to the same surface for more than 60 seconds, However, regrappling the same surface resets this timer.

Grappling hooks do not damage monsters anymore as of the release of patch 1.0.4, and instead pass through them.

Grappling hooks can be used to pass through a chokepoint that you would not normally fit through. The endpoint still needs to be at least 3 blocks high and 2 blocks wide, but you can pass though a more narrow gap to get there. As an example, face left in a three block high, horizontal tunnel. Dig the two blocks above your head on the left, and the three to the left of that, starting with your head level, and the two above. You will not be able to jump through that gap, but you can grapple through it. An upgraded version of the grappling hook called the Ivy Whip can be crafted from the grappling hook and items found in the Underground Jungle. The Ivy Whip can be created from a Grappling Hook, 30 jungle roses and 3 vines.

It is an absolute necessity for mining, trekking, and is a massive help during gameplay, as it helps players reach heights and areas that were before near impossible to reach, or create quick escapes from water and mobs alike. As an added perk, by firing the grappling hook at the ground while falling, fall damage can be negated; however, it should be noted that the grappling hook should be fired about 2 seconds before impact, or else the grapple will not hit the block before you do.
