How are people selling their rings like that? I thought they were soul bound?? :/
There was a date, I think it was December 2008, where rings were soulbound because people were buying their ways through the game. However, when implemented any ring that hadn't been equipped or charge swapped since the soulbinding remains unbound, until it is either charge swapped or equipped. So the rings you see on the MP are rings that in all that time have not become soulbound.
Exceptions to this rule are: Sweetheart, Fortune's Favor, and Sugar Rush. These three rings will never soulbind because of their status as event rings.
