Update 2/25/16: I’ve added these rings to a collection of magical rings in Dragon Magazine #117 that I’ve made available in pdf format on the DMs Guild. Bazaar of the Bizarre: Rings that Do Weird Things is now available as a Pay What You Want!
Once again we get a couple of issues of Dragon without anything immediately able to be converted. Some nice fluff as well as well as some rules systems that won’t need to be converted. Dragon #82 had something good in it. A collection of rings sent in by readers.
I remember playing The Baton Races of Yaz game that was included in this issue.
