Adamantine

This alloy, of five-eighths adamant to two-eighths silver and one-eighth electrum (itself a natural alloy of silver and gold) retains the hardness of adamant, but combines it with a rugged durability that makes adamantine so hard to shatter that it is the favored substance for the making of war hammer heads, the best nonmithral armor, and harbor chains. (By one of the mira¬cles granted by the gods, adamantine can also be derived by com-bining steel and mithral —if one knows how. ) Adamantine is black, but has a clear green sheen in candlelight—a sheen that sharpens to purple-white under the light given off by most magi¬cal radiances and by will-o'-wisps. Adamantine is tricky to make, and must be forged and worked at very high temperatures by smiths who know exactly what they are doing and who have access to special oils to slake and temper the hot metal in. Almost all such expert smiths are dwarves, as the Deep Folk guard the secrets of working adamant jealously, but a priest or wizard seeking to enchant items can make use of fin¬ished adamantine items and need not necessarily have to work with a smith to create an adamantine work anew. Adamantine readily takes enchantments, adding a +2 bonus to all saving throws of awakening, enchant an item, holy vesting, and wondrous web spells cast upon it. It is often the primary material for enchanted armors. Items made primarily of adamantine automatically succeed in all item saving throws vs. normal fire, cold, and electricity. They receive a +4 bonus to all item saving throws vs. acid, crushing blow, disintegration, fall, magical fire, and lightning.
