This list of diagrams shows the required materials needed to make the items they specify. These diagrams range from creating weapons and armor, to making runestones and glyphs to enhance them, to taking existing crafting materials and turning them into other items needed for higher strength weapons and armor! Also important are the repair kits that can be made for weapons and armor. You can save yourself a lot of money with repairs if you can keep repair kits in your bags, especially during lengthier quests that keep you far from towns and in frequent combat.
