Battlegrounds Buddies are here! Battlegrounds is getting a massive shake-up in Patch 22.2 with the introduction of 75 new minions! Each minion is a different Hero’s special Buddy, designed to synergize with that hero. Friendships like this can’t be bought in the Tavern; Buddies are earned as you play! Fill up your Buddy Meter to get up to three copies of your Buddy throughout the match.
