Champion Mastery is now live!
This new system will allow you to gain points depending on your game performance. As you gain points, your Grade will increase from D all the way up to S. As you accumulate more Mastery Ranks for Champions, your Mastery Score will increase. This system will start working when your account gets to Level 5.
Ranking up in Champion Mastery Ranks will net your new rewards. Your rank will occasionally show up above your Champion while in-game.
