Obtaining

 * Found on a corpse in Stormveil Castle.
 * From the Stormveil Cliffside site of grace, proceed up into the storeroom littered with explosive barrels. Take the ladder behind the door opened by the Rusty Key and turn back south. Jump across two sets of scaffolding towards an opening on the right wall lit by a torch. Head south along the wall into a small tower, where the corpse will be found in the opening overlooking the storeroom.
