Adamantine

An alloy of adamant, electrum, steel, and mithril,  adamantine is fully as hard as adamant yet possessing a rugged durability making it almost unable to be cracked, much less shattered as adamant may be. Black in hue, but possessing a green sheen which turns to purple-white under most magical radiances, adamantine can rarely be mistaken for any other metal. Unlike adamant, it can be affected by fire & heat, although the temperatures needed to work it are excruciatingly high and it is tricky to work with at best, requiring special oils to slake and temper the metal properly. Very receptive to enchantment, enchanter spells cast upon it tend to be 10% more effective than normal. One thing frightens mages about adamantine, there are at least 4 recipes for it from completely unrelated metals (the combination above is considered "true adamantine"), hinting that it, like orichalcum, is a metametal rather than a specific magical substance.
