Since the ring of wealth update, I found the ring quite useful. A lot more than it used to be. A little table of when the thing has enhanced stuff for me. This is only ROW drops, not other good drops. The cave horrors were glitchy and the ring shined every time I killed one, so I cannot be sure when it was real and when not. Shade keys aren't listed, unless they give a very good reward. Barrows loot also isn't listed, unless I get a piece of equipment.
