- You may also be looking for Summoner Mastery, a retired feature of the game.
Champion Mastery is a progression system which tracks a player's aptitude for and experience with each champion. At the end of every game in certain queues, the player earns Mastery Points and their performance on the champion is compared with other players' to assign a grade. Each split, the player can complete Mastery Milestones for that champion by achieving increasingly impressive grades. Completing Milestones awards 
Marks of Mastery (among other rewards), which are required for unlocking new Champion Mastery levels.
Progressing in Champion Mastery is free for all players, so long as they have reached summoner level 5. In patch V10.5, Eternals were introduced as a premium expansion to Champion Mastery.
Riot's official support page on Champion Mastery can be found here.
Eligibility[]
Players can earn Mastery Points (MP) upon finishing a game in the following matchmade queues, provided the champion is owned:
Summoner's Rift: Quickplay, Draft Pick, Ranked Solo/Duo, and Ranked Flex- Howling Abyss: ARAM
- All Featured Game Modes: Ultra Rapid Fire, One for All, Nexus Blitz, etc.
Grades are only given out in the first and second types of queues, however.
Grades & Points[]
After an eligible game, the player receives a grade based on how well they performed compared to all other players in the region that have played the champion-position combination (e.g. 
Vel'Koz 
bottom lane will only be compared to other Vel'Koz bottom lane players). They are then awarded mastery points (MP) based on that grade, the team's grades, and their premade party's size (if applicable).
A higher grade means the player will earn more MP. The possible grades are (from highest to lowest): S+, S, S-, A+, A, A-, B+, B, B-, C+, C, C-, D+, D, D-.
| Premade Size | Premade Bonus |
|---|---|
| Party of one | No bonus |
| Party of two | + 2% |
| Party of three | + 4% |
| Party of four | + 6% |
| Party of five | + 10% |
- Notes
- Earned grades do not persist through transfering servers, and reset per ranked split. Mastery points and levels still persist.
- The mastery grading system is not influenced by matchmaking rating (MMR).[1]
- Performance uses a mix of core game metrics that Riot is confident cannot be abused through means such as exclusively farming or spam warding, which would result in players ignoring the majority of the game and degrade its quality.[2]
- Mastery points do not decay.[3]
- Progress is not reset in the event of any type of champion update.[4]
- Progress is also locked for every player in the small interim between ranked splits where Ranked queues are disabled to prepare for the start of the next split.
Milestones[]
Achieved grades also progress the champion's mastery track. The track is divided into four milestones, with a fifth repeating one, and each milestone requires achieving increasing grades. Only the highest grade available is considered per completed game.
The mastery milestone track's progress can be viewed in the Mastery tab of the champion's overview. The champion's current mastery points, level, crest, and acquired Marks of Mastery are also displayed there.
The track resets per split, renewing all available rewards. There are two categories of Hextech Chest that can be earned through milestones: they differ in the number of chests that can be earned per split.
| Milestone | Requirements | Rewards |
|---|---|---|
| I | 1 game B- and higher 4 games of C- and higher |
1 Mark of Mastery 1 Hextech Chest (first type, up to 6) |
| II | 1 game A- and higher 4 games of C- and higher |
1 Mark of Mastery
|
| III | 1 game S- and higher 4 games of C- and higher |
2 Marks of Mastery 1 Hextech Chest (second type, up to 25) |
| IV | 1 game S- and higher 4 games of C- and higher |
2 Marks of Mastery Crest Highlighting VFX |
| Bonus (infinitely repeating) |
3 games of S- and higher | 1 Mark of Mastery
|
Level Thresholds[]
Mastery levels are unlimited. From levels 1–10, the mastery crest upgrades along with the level. After level 10, numerals on the golden 
level plate drawn over the level 10 crest showcase the player's achieved level instead. Upgrading is automatic after passing the requirements and doing so notifies the player through a celebratory toast.
Unplayed champions are considered level 0. After playing a single game, the champion immediately enters level 1 and starts progress towards level 2. Free and unowned champions can only progress in their mastery points (all other aspects of Mastery are unavailable however, including the crest upgrades, until the champion has been unlocked).
At level 10, the champion's title permanently unlocks for use as a unique profile title.
| Level | Requirements | Cumulative MP |
|---|---|---|

Prominence[]
At levels 4 and above, the mastery crest can be showcased through the mastery emote in-game (default: Ctrl+6 or entering "/masterybadge" in the chat).
The mastery crests are commonly featured within banners in various parts of the Client:
- In the Profile
Displayed in the Overview tab of the Profile screen is the player's total Mastery Score (sum of all mastery levels achieved), then first and foremost the champion with the highest mastery level. Hovering over this Mastery panel shows the player's top 3 champions in level, as well as their best grade earned during the current split.
- In the Loading Screen
Displayed in the Mastery card within the loading screen.
- In the kill announcements
- Displayed below the champion's circle icon.
- In the Death showcase
- In the Post-Game Lobby
- A text callout within the chat will notify the team if a player has achieved an S grade or a new mastery level.
Mastery Sets[]
Champion Mastery displayed within the Collection
Each ranked split, a group of ten champions that the player may be interested in progressing milestones is curated by Riot, called a Mastery Set.
- 3 of them are part of the player's most played champions in the recent ranked split and/or across the life-time of the account.
- 4 of them strictly match the player's role/class preferences.
- Another 3 are loosely related in play style to the player's preferred champions.
The current Mastery Set can be viewed at the top of the Champions tab under the player's Collection.
A Mastery Set includes its own progress track, and provides unique rewards for completing a certain number of Milestones for the champions within the Set.
- At 12 Milestones completed, earn the first and ultimate reward for finishing the Set: a Superior Mastery Chest, which is part of the same loot pool as a regular Masterwork Chest.
- At 24 and 40 Milestones completed, earn 750 and 1250 Blue Essence, respectively.
