Just a quick note for those that have some extra money laying around. After I get a shop reset I buy the legend AND the epic(orange) items for sale in the shop.
The epic items have a chance to become legends and when they do, they can also become eternal or crystal as well!
I get about 1 in 6 epics to turn into legends (a rough average). I can’t tell you how many of those become crystal or eternal because I don’t try to track that. I am just happy when it happens.
