This piece, along with the rest of the set, is given to the Dragonborn by Karliah before performing the initiation ritual of the Nightingales during the quest "Trinity Restored". All pieces are obtained when activating the Armor Stone, emblazoned with the Nightingales symbol, inside Nightingale Hall.
The piece bears an enchantment, the magnitude of which is dependent on character level. Three tiers are available and the item with the strongest enchantment can be obtained after level 32. The character level when the quest "Trinity Restored" is started determines which tier will be granted.
