Crafting is one of the crucial parts of the game Moonlighter.
Moonlighter has a crafting and enchanting system that is key for player progression.
Dealing with the other merchants in town Will can craft new armors and weapons, and enchant existing equipment. To craft/upgrade/enchant equipment, some specific items and large amounts of gold will be required.
Upgrading and Enchanting will result in more powerful equipment, some of them with special features, adding a great deal of flexibility to the way the equipment is used.
Player can get exact receipts on crafting in each vendor, or here on Wiki.
Also there is a Wish List in the game that allows player to add exact items to it (craftable ones like armor and weapons) in order to mark all of the materials obtained with a little star in upper left corner in item in the slot.
