Mithral
Mithral is light and hard metal described in
the DUNGEON MASTER’s Guide. Some foolish bards believe
that mithral can be combined with steel to form
adamantine, but such tales only cause uproarious laughterin dwarven communities.
Mithral weighs half as much as steel, has hardness 15,
and has 30 hit points per inch of thickness.
