Mithral is a rare silvery, glistening metal that is lighter than iron but just as hard. When worked like steel, it becomes a wonderful material from which to create armor and is occasionally used for other items as well.
Crafting either a weapon or an armor out of mithral adds 10 to its difficulty class.
