I have a pair of legendary “pants” called the “Novice Wood Ring” in my inventory. They have no stats, no legendary power, and I can’t get rid of them. It has the icon like it’s borrowed from the war band items, but I can’t return them. I did have an offhand that I was using from the warband chest, but these were in my inventory as well. It won’t let me store, salvage, or destroy them… just taking up inventory space
