I noticed that my inventory tells me I can't sell my rings cause they are linked to my soul.But there are listings of rings in the market...So how do I sell my rings???
There is no way to sell your rings anymore. The rings in the MP are merely from the early stages of zOMG where rings were not bound to your account. There are only three rings now that no matter what they will not bind to your account: Sweetheart Ring, Fortune's Favor and Sugar Rush.
