RAINBOW GEMS! What are they? How do you get them? 🌈 To acquire a rainbow gem you have to upgrade 3 gems of the same category and there will be a chance to mint a rainbow gem of that quality! Once you have a rainbow gem you can apply it to your rainbow sneaker to enhance the efficiency. 🌈💎 To note: Rainbow gems cannot be traded on the marketplace and used for further upgrades. #rainbow #gem #stepn #upgrade
