I'm having trouble obtaining the new chest piece you get from completing the skeleton endurance trial in Seeker,Slayer,Survivor. I complete the challenge only for combat to not end and the item to not appear in my inventory once I transition back from the area. I will include my save file and a link to a video with the problem in action. Any and all help would be appreciated!
