Black Mithril (3.5e Equipment)
From D&D Wiki
 Black Mithril
Black Mithril is a very rare black form of the glistening metal Mithril that is even lighter and harder than Mithril. Only found in the depths of Moria, it is called "The Rogue's Metal" by some. When worked like steel, it becomes a wonderful material from which to create armor and is occasionally used for other items as well. Most Black Mithril armors are one category lighter than normal for purposes of movement and other limitations. Heavy armors are treated as medium, and medium armors are treated as light, but light armors are treated as only a quarter of the cons and twice the pros of light armors. Spell failure chances for armors and shields made from Black Mithril are decreased by 30%, Armor class is increased by 2, and maximum Dexterity bonus is increased by 5, and armor check penalties are lessened by 4 (to a minimum of -4, which is otherwise a +4 on such penalties).
An item made from Black Mithril weighs one-fourth as much as the same item made from other metals. In the case of weapons, this lighter weight does not change a weapon’s size category but does change the ease with which it can be wielded (whether it is light, one-handed, or two-handed). Items not primarily of metal are not meaningfully affected by being partially made of Black Mithril. (A longsword can be a Black Mithril weapon, while a scythe cannot be).
