Medals are awarded at the end of matches for exemplary performance and for meeting certain requirements. While each Champion has specific Medals that only they can earn, there are a large amount of Medals that any Champion can earn. Medals will grant a large amount of XP after a match, and performing better will earn you more Medals. See how many Medals you can earn in a match!
A record of Medals you have earned can be found in the Player Profile section, where you can filter by Champion and Game Mode. You can also find descriptions of each Medal, so you can learn how to unlock each one.
Completing Medals will often allow you to complete Challenges, earning greater amounts of XP or rewards.
