This meant they couldn’t visually display their prowess with a hero in-game if there was a non-master skin they liked better. Additionally, once players purchased a master skin, they'd then have to choose whether to use it or another skin in-game. However, when the developers re-evaluated master skins, they realized that Master skins created situations where players had to choose between unlocking a hero or unlocking a master skin, which was a battle that heroes won far more often. They were intended to help you flaunt your depth of experience and time investment with your favorite heroes. They had a price of 10,000 and could not be bought in other way. When Heroes of the Storm first launched, Master skins were a type of skins that could be obtained only after a player reached Hero Level 10 with the respective hero. These rings signify experience playing individual heroes and let other players know that you know how to play your chosen hero, so Mastery Rings are hero-specific. Q: Do I purchase these rings for each Hero separately? A: Yes. Q: Can I get Mastery Rings for more than one hero? A: You can get Mastery Rings for as many heroes as you like, given than you’ve reached at least level 15 with those heroes.
