Mastery is achieved by earning Mastery Points (MP) after playing games with a champion you own in specific matchmade queues.
To elaborate, here's a breakdown of how you accumulate mastery:
-
Play Matchmade Games: You need to participate in games within designated matchmade queues. These include:
- Summoner's Rift: Quickplay
- Summoner's Rift: Draft Pick
- Summoner's Rift: Ranked Solo/Duo
- Summoner's Rift: Ranked Flex
-
Own the Champion: This is a crucial requirement. You cannot earn Mastery Points on a champion unless you currently own them. Free champion rotations do not count towards mastery.
-
Earn Mastery Points (MP): After successfully completing a game in one of the eligible queues while playing a champion you own, you will be awarded Mastery Points. The amount of MP earned varies based on your performance and other factors. The system evaluates your performance relative to other players using the same champion in the same role. Better performance yields more MP.
In summary, you gain mastery over a champion by playing them in appropriate game modes while owning them, and by performing well to earn Mastery Points.
