But what would be the point of handing off some rings that nobody but you can use?
Obviously, you'd want to keep that bling-bling for yourself, where they can be put to good use. They're wasted on henchies. And what happens if Mandy wants, say, to chuck a fireball or two, and that particular ring is on Raza's finger out in East Lower Afghanistan, and he's gotta wait on FedEx to pick it up.....?
