Without a Grappling Hook, you’ll find that many important paths and areas are closed off to you.
And that just won’t do.
To craft the Grappling Hook, run with this:
Let’s go over all that in more detail.

String is easy to come by - all you need is to craft it out of 3 Plant Fiber.
These NPC enemies will usually give you Shroud Spores as loot once you’ve slain them.
As for Metal Scraps, your best chance of finding them is by scavenging around towns and villages.

These little pockets of civilization usually have bits of Metal Scrap lying around.
Once you’ve got all the materials, craft the Grappling Hook at the Workbench.
Tapping this button will automatically use your grappling hook on the grapple point.

There are two types of grapple point.
Some will simply pull you towards the grapple point itself in a straightforward arc.
Others will allow you to swing from the grapple point to cross a gap.

Besides that, there’s not really much to using the Grappling Hook.
It doesn’t have a durability meter, so you don’t need to worry about it breaking.
That’s all there is to creating your very own Grappling Hook in Enshrouded.
