Badges are one of the ways you can show off your accomplishments in the game! You can get badges by completing certain events and achievements. Once you have collected a badge, you can use it as your profile picture, available to view during battles or in alliances. 

To do so, access your profile through your player level icon and select the option to edit your profile picture. You can track your progress by viewing the "Recently Collected Badges" subsection of your profile. You can also see a fellow DPG member's badges by viewing the Recently Collected Badges on their profile.
