The Diamond Armor, Armlet, Helm, Gloves, and Shield appear as mid-powered pieces of armor. They resist Lightning-elemental damage. The armor, helm, gloves, and shield are wielded only by the Knight, while the armlet can be wielded by any job. The armor, helm, and armlet are found only in the Sunken Shrine. The gloves and shield can be found there, and also in the Flying Fortress.
