To upgrade a tool, you need to find a structure called a blocked passage, dig it up and find a treasure chest containing a copper rune. Also, to upgrade, you need to melt a copper ingot in a furnace to get molten copper. Using a copper rune and molten copper on a blacksmith&#8217;s table, you can upgrade any of your tools, making them much more efficient.**<\/p>\n<p>The official E21S author page and the latest mod versions are only available on modrinth.
