Champion Mastery

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 and experience with each champion. At the end of every game, players receive a grade which scores their performance in comparison to the whole player base in that respective champion and position combination. These grades then translate into a point score which accumulates over time, eventually unlocking new Champion Mastery levels and rewards as the player advances through the system.

While implemented with patch V5.6, this system wasn't fully implemented on all servers until patch V5.8.

Riot's official support page on Champion Mastery can be found here.

How the System Works

Eligibility

At summoner level 5 and higher, summoners are eligible for Mastery points. Champion Mastery points are eligible on matchmade games of:

• PvP Summoner's Rift (Blind Pick, Draft, Ranked)
• PvP Twisted Treeline (Blind Pick, Ranked)
• PvP Howling Abyss
• All Featured Game Modes ( Ascension, Legend of the Poro King, Ultra Rapid Fire, Hexakill, All Random Summoner's Rift, One for All, etc...).

All Co-op vs. AI modes and custom games are not eligible for Champion Mastery.

Grades

Grading score

Every eligible game you play with a champion, you will earn a grade based on how well you performed in comparison to all other players in your region that have played your champion-position combination (e.g. Vel'Koz bottom lane will only be compared to other Vel'Koz bottom lane players), with S+ only being awarded to the highest percentile of players.

These grades only represent how well you performed in that specific game. However, a higher grade is worth more points towards your mastery of that particular champion.

The possible grades you can achieve are (from highest to lowest): S+, S, S-, A+, A, A-, B+, B, B-, C+, C, C-, D+, D, D-.

Notes

• While you are graded versus all players in your region, the grading system is not influenced by your matchmaking rating (MMR). Note that it is still possible for low-elo players to consistently get S+ if they are really good on a champion.
• Performance uses a mix of core game metrics that Riot is confident cannot be abused through means such as AFK farming or spam warding.
• Riot will not reveal the exact factors that determine grading to prevent players from attempting to game the system.

Champion Points

Grading system

Champion Mastery is currently divided into 7 levels, with level 7 being the highest. To progress through the levels, a player needs to play games on your champion and earn champion points (CP). The amount of mastery points earned is displayed as a circular progress bar around your grade in the post-game screen. While a higher grade is worth more mastery points, the amount of mastery points gained is also influenced by team performance and party size (premade bonus).

$\pagecolor{Black}\color{White}{\rm Champion \ Mastery \ Gain} = {\rm Individual \ Contribution} + {\rm Team \ Performance} + {\rm Premade \ Bonus}$

Team performance is affected by whether or not your team wins.

Premade bonus is awarded based on group size:

Premade Size	Premade Bonus
Party of one	No bonus
Party of two	2% of CP earned
Party of three	4% of CP earned
Party of four	6% of CP earned
Party of five	10% of CP earned

Players can track their progress with each champion outside the post-game screen in the Champion section of their profile. Furthermore, the three champions with the highest point score are displayed prominently on the profile landing page, next to your ranked standings.

Levels 1 to 5

Unplayed champions are considered level 0. After playing a single game, players immediately enter level 1 and start their progress towards level 2.

Mastery points can be earned beyond level 5. The total is displayed below the champion portrait on the profile screen together with the level 5-7 crest.

The following describes the amount of Champion Mastery points required to go from one level to the next:

Level	CP Required	Cumulative CP Required	Cumulative CP %
1	0	0	0
2	1800	1800	8
3	4200	6000	28
4	6600	12600	58
5	9000	21600	100

Levels 6 and 7

Champion mastery tokens in Hextech Crafting

Upon reaching level 5, as noted above, champion points can still be earned but will not continue to advance mastery level. Instead, levels 6 and 7 are earned through Hextech Crafting.

Gaining tokens

At level 5 with a champion, that champion becomes eligible to earn Mastery tokens. These tokens can only be earned on matchmade Summoner's Rift normal and ranked games.

• At level 5, receiving a grade of S-, S or S+ grants one Mastery 6 Token.
• At level 6, receiving a grade of S or S+ grants one Mastery 7 Token.

Using the tokens

Leveling up a champion's mastery requires combining the following:

Level	Cost
6	Two Mastery 6 tokens + 2450
7	Three Mastery 7 tokens + 2950

In both instances, the blue essence can be replaced with a champion shard or champion permanent of that champion.

Note that you cannot gain more tokens once you have 2 tokens for Mastery 6, and 3 tokens for Mastery 7.

Rewards

There are 7 levels of Champion Mastery currently obtainable. You will earn the crests below as you accumulate Champion Mastery points. In additions, levels 4 and up get access to an in-game Mastery badge emote, a loading screen border (visible to allies only), and an in-game announcement banner.

• Progress will not be reset in the event of a champion rework.
• Visibility of Champion Mastery to other players:
  • Profile Page:
    • Top three champions (by level, then by points)
    • Mastery Score: Sum of all Mastery levels attained
  • Loading screen and in-game rewards as detailed above
• When changing server regions, the highest grade earned on that champion will be cleared, however the mastery rank obtained pre-migration will be kept. 

FAQ

Details:

Will I get xp credit for how much I've already played a champion?
We’re not currently planning to do this. Because this is a new system, we want players to feel progress (and earn rewards!) based on how well they do and the champions they choose to play.

What goes into the grading system? How do you calculate it?
It’s based on the champion and role that you just played in a game. So, for example, we look at Annie mid differently to Annie support. We take a series of performance metrics and compare how you do to all other players in your region in your champion / position combination. It is percentile driven - so earning a high score means you performed in the top x% of players on that champ in that position. The grade itself governs the point gains.

How many games will it take to level up?
We expect players to take 15-30 games to level through the first set of levels (1 through 5). We’ll be unlocking additional levels later.
Levels 6 and 7 now available

Is this going to feel grind-y?
This system is performance based - the quicker you master a new champion, the quicker you’ll make progress.

At the same time, we want it to be accessible enough that all players can feel good about improving.

We’re tuning this system so that you will be leveling up the set of champions that you really enjoy playing and getting meaningful feedback on your performance each game. The ceilings are intentionally set low for each individual champion to avoid making it feel like a grind.

Can you be demoted?
No demotions or decay is currently planned.

What other kinds of rewards are planned for the future?
We are going to see how people enjoy using the system and what they like about it before we finalize our future plans. We’d love feedback on this.

Will skins ever be a reward?
It’s not something we’re considering right now, but we are exploring other ideas for unique rewards we think you guys might like.

Will this work on Dominion and ARAM? Will it ever in the future?
We’re currently limiting this to SR.
Now available on all player vs. players modes on all maps. Co-op vs. AI and custom games still do not reward champion points.

Can the enemy team see the crests in-game or in the loading screen?
Not initially, but we may revisit this in the future.

Can other players see my grade at the end of the game?
No. These grades are for you and not something for others to be able to see. They will not available to 3rd party sites either.
Grades of S- and above are announced to the allied team.

Will the score account for AFKers?
Can confirm, AFKing will result in a bad score."
