Valkyrieβs Prosthesis is an Elden Ring quest item required to advance Millicentβs questline. To progress her quest, you must locate the Valkyrieβs Prosthesis in order and unlock various powerful weapons. Throughout this guide, weβll show you how to get Millicentβs prosthetic arm by indicating where to find Valkyrieβs Prosthesis in the video game developed by FromSoftware and how to use it.
Where To Find Valkyrieβs Prosthesis
The Valkyrieβs Prosthesis can be found at The Shaded Castle, a fort in the Altus Plateauβs northwest region.

You can enter the fort through many breaches in the walls, but youβll want to make your way through the castle to the northwest edge to find the Valkyrieβs Prosthesis. Use your horse to jump over the low parts of the wall to get on top of the walls. If you stick to the exterior walls, youβll find a single Cleanrot Knight guarding a room filled with statues.

A treasure chest containing the Valkyrieβs Prosthesis can be found in the room beyond the Cleanrot Knight.
How To Use Valkyrieβs Prosthesis
Millicentβs questline is advanced by using the Valkyries Prosthesis. If you havenβt already aided her in Caelid, you must first speak with Gowry at Gowryβs Shack, south of Sellia, School of Sorcery. Heβll put on the path to find the Gold Needle to cure Millicent of Scarlet Rot.
After you cure Millicent in Caelid, she can be found slightly northeast of the Erdtree-Gazing Hill Site of Grace in the Altus Plateau region.

Speak with her multiple times there, and sheβll explain that sheβs useless in a fight without her arm. If youβve obtained the Elden Ring Valkyrieβs Prosthesis, deliver it to her here to progress her quest.

She will thank you and tell you that the arm will allow her to fight again. After defeating the Godskin Apostle boss, Millicent will move to Dominula Windmill Village. Millicentβs quest is pretty lengthy; therefore, we wonβt go into full depth here. It is important to remember, though, that the Valkyrie Prosthesis is an essential item in advancing her quest.
