Ahzidal's Ring of Necromancy is a unique piece of enchanted jewelry found in The Elder Scrolls V: Dragonborn. The ring can be best put to use with the ritual stone. Equip any stone with your bare head, then equip the ritual stone with the aetherium crown. Then equip the ring of necromancy, and use the ritual power to raise an army of undead. Remove and don back the crown to resset the ritual power, and each time you use it, your army of raised undead will explode, dealing 50 points of frost damage each.
