I have just purchased a legendary ring from the vendor in OT, but have no information on how to get the new gems that fit into the slots.
Have spoken to GMs and they state they are not able to provide that information.
I find it rather frustrating that the devs have made available this ring and yet will not allow you to add the necessary gems to it - or provide information on its availability.
It would be helpful if someone could reply to this post stating any plan/timescale for these new items.
