Aran Ring

What could they do now that they've already made three different rings? Remove the first two? "Oops, guess that wasn't smart."

a) do that (I'd be fine with this, level 70 is not even hard)

b) figure out how to make a quest give stat improvements to items, and just have a single ring that is "upgraded" by changing its stats instead of exchanging it, resulting in a single item id. They already have NPCs that give out non-average equip stats, should be possible to do this. Maybe just by taking away the one you've got, giving back an above average one. (or start with below average at 30, then get average at 50, then above at 70 - whatever)

Or if they want to, set it to un-hammerable and give it 2 slots, and a special scroll... but that's more work.
