Hearthstone will be getting a big update next week, but this time, it’s not to the traditional Standard and Wild competitive modes. Instead, this update will focus mostly on the auto-chess Battlegrounds mode, offering the first major overhaul to the mode since launch. The update coming January 25 will add “Battleground Buddies.”

The new Battlegrounds buddy system will give each of the 75 Battlegrounds heroes their own unique “buddy” minion, specifically designed to synergize with and enhance that hero’s unique hero power. A Buddy Meter fills up during combat, awarding you first with a copy of your Buddy and then with two more to make a triple (golden) version. While the Buddies will enhance your hero power and general strategy, they will take up one of the seven spots on your board, so it will take careful strategy to make the most of them.

Past Battlegrounds updates have added new tribes or armor ratings for each hero for balance reasons, but this is the first time the mode has added an entirely new game element. Blizzard also announced a handful of new heroes joining the lineup as well.
