There has been only one set of Ascended Adamantium Armor made to date, made as the zenith of Giant engineering as the armor to trump all armors and weapons. It's making was cut short by the outbreak of the war that eventually destroyed the Giants, leaving the armor nowhere near what the Giants wanted it to be, but still much more powerful than the crude Adamantium Armor made by Humans. It can deflect and even absorb magical spells, shift to shape the size of it's wearer, and cleave through steel, bone, and flesh like air.
Due to it's unfinished state, it has a few negative effects on it's user. The only set made is owned by Ezyrim Inok, the Fatebreaker.
