Champion Mastery

Champion Mastery is a new system that will be implemented where players will get points, ranks and rewards for playing champions. Its currently tested at the PBE.

How the System works
Finish a game of League and you’ll earn points for your champion based on your team’s performance as well as your own contribution. Earn enough points and you’ll level up that champ’s mastery level, giving you rewards as you progress.

Grades
Hover over your Champion Mastery points bar in the post-game screen and you’ll see the grade that our new system gives you. Grades are awarded based on your overall performance in the role along with the champion you’re playing and, crucially, where you’re playing them.

Leveling Up
Checking your in-client profile, players can see new stats telling them their mastery scores, a sum of all the players mastery ranks combined.

Rewards
There are 5 "grades" of mastery: D, C, B, A and S. Here are the crests players champions will earn as they rank up:



Rollout
Riot is kicking off the rollout with a PBE stint from 3/11. If all goes well, a couple of weeks later they will then launch a beta in a single region, focusing on Summoner’s Rift normal queues to make sure the feature’s stable for expanded use. Riot will read through player feedback and keep them updated with their progress.

Eligibility
All summoners who’ve hit level five or higher will be eligible for Mastery points. However, at launch, it’ll only support normal games on Summoner’s Rift.

The Future
This is just the beginning for Champion Mastery. As the system matures, we’ll unlock extra tiers and rewards as we build on the program!

Trivia

 * Players can only see their scores and not other players Mastery scores.
 * This also implies to third party sites that usually display other players achievements.
 * Champion grading is determined using a combo of personal score, teammate scores, win or loss, game length and a few other factors.
 * Currently, Riot is not planing of making players lose their champion grade points from losses, but a loss will significantly lower the amount of grading points a player gets as oppose to winning a game.
 * This will be a system only implemented on the Summoner's Rift map and playing against bots will not be considered into the grading system.
 * Currently, Riot is not planing on retroactively giving Champion Mastery rewards when they implement this system.
 * Tier 5 appears to be split into three sub-grades, represented by a Red Triangle, Magenta Diamond and Cyan Hexagon (in order of least to most impressive).
 * The in-game emote causes the champion to produce a mastery badge. Unlike other emotes it doesn't seem to interrupt anything. Default key binding: Ctrl + 6.
