The Craft Armor and Craft Weapon skills are used to create basic non-enchanted armor and shield from various materials. The crafting skill required depends both on the type armor or weapon being created and the type of material used. Crafting armor, a shield or a weapon requires an item mold for the type of weapon or armor to be created and an appropriate amount of the right raw material.
Molds and raw materials (metal ingots, woods and hides) can be bought from almost all of the merchants throughout the game, and some hides can be found on the bodies of various animals. The amount of raw material required is usually stated on the item mold.
To craft a set of armor or a weapon, simply place the item mold and the raw material into the blacksmith's bench and then use the blacksmiths hammer on the bench.
Crafting weapons and armor from basic materials generally require low skill levels, but crafting items from more exotic materials can push the crafting skill level to the highest levels required in the game. However, using exotic materials for basic crafting can result in weapons and armor with added properties. e.g. Mithral armor is extremely light, while adamantine weapons can cut through the defenses of some of the most stubborn monsters.
