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 and select the option to edit your profile picture. You can track your progress by selecting "Recently Collected Badges". You can also learn how a fellow DPG member got theirs by selecting the Recently Collected Badges on their profile.
