Uptrade
With three different Collections, the Uptrade system is divided into two.
Please note that you must have at least one Artifact left (for each) to Uptrade. You can Uptrade to any tier right away.
a) For the Standard and Sponsored Collection, you’ll need 6 Artifacts to uptrade to Purple and Magenta, and 8 Artifacts to uptrade to Red and Gold.
b) For the Mini Collection, you’ll need 2 Artifacts to uptrade to any tier higher than Blue.
