Valkyrie's Prosthesis is a quest item inElden Ring required to progress Millicent's questline once Tarnished have cured her of Scarlet Rot. After speaking with Millicent and Gowry in Caelid, the player will reencounter the maiden north of the Erdtree-Gazing Hill's Site of Grace in Altus Plateau. She will discuss her plans to continue her search for Malenia but rue that she cannot aid the Elden Ring protagonist in battle due to losing her sword arm. However, adventurers can solve this problem by giving her Valkyrie's Prosthesis.
Valkyrie's Prosthesis is located within the Shaded Castle, a poison-ridden fortress on the northern side of the Atlus Plateau. To reach this location, Tarnished must journey north within the valley between Mt. Gelmir and the eastern portion of the Atlus Plateau. However, if adventurers are trekking from the Road of Iniquity in the north, they can safely jump down the cliff by landing on the Spiritspring Jump across the trail from the Old Altus Tunnel.

Once Tarnished arrive at the Shaded Castle, they can no longer Torrent within the vicinity, making it challenging to avoid the poisonous swamp. As a result, adventurers are advised to carry Neutralizing Boluses or have the Elden Ring's Cure Poison Incantation equipped just in case. Additionally, Valkyrie's Prosthesis is stored within a chest in the northeastern tower of the castle. Accordingly, the player does not need to defeat Elemer of the Briar, the Dungeon's boss, to acquire the prosthetic arm.
