To craft new armor or weapons, you need a schematic and enough materials. The schematic determines the appearance and potential power of the crafted item. The materials determine the specific stats and powers that will be added to the new item. Each crafting schematic has one or more slots. Each slot accepts a specific number of materials of either metal, cloth, or leather. Fill all available slots to craft an item. There are five different types of crafting slots: utility, offense, defense, damage, and armor. You can freely remove and add existing upgrades or exchange them between different items.
