I have a TON OF ARMOR AND WEAPONS THAT I DONT USE ANYMORE !!! If only we could sell things that we dont need anymore, but a bit less amount of gems than when we bought it. Because I dont have that many gems, but I have a lot of things, so it would be really cool if we are able to sell things.
This has been requested several times already and it is in the plans. However, it is not a high priority at the moment, as far as I can tell. Subscribe to this GitHub thread to stay updated.
Cool. I look forward to it.
