I am clueless to how this works. I found a hammer and an anvil. I read in another post you need a workbench, but I don't know what it even looks like.

Thanks!

Hey Jonny, there are limited ways to repair equipment and it takes away 10 max durability. You can either find a single-use whetstone (Fallen Knight also starts with one) or find a Grindstone in one of the locations for unlimited repairs.

Thanks Artur! This also works for armor?
