[Taqwus]

I could see a case for some auto-equipping cursed items, depending on the nature of the curse (think powerful items that either can mask the curse or otherwise appeal to the finder), but even that should require an MR check.

Something like Stormbringer might be pretty hard to put down, or to meekly set aside and deliver to the lab, despite the downside of occasionally going berserk and turning on your associates...
