Honestly, it's a lot more trouble hunting down things like that ring than just reading about them. You have to put in hours of hard labor digging through the dirt for them while being pursued by people who were never told that you're allowed to be doing this, and then if a legend wasn't all that detailed about what the thing does you have to figure that out on the fly, and that's if someone else didn't get their hands on it first, because if they did then usually they want to kill you to keep you quiet...
