Today's Hearthstone Patch 26.4 gets the game ready for the imminent launch of the Audiopocalypse mini-set, the return of Diablo, Battlegrounds updates, Duels changes, and more.


The Audiopocalypse

Quote From Hearthstone

The Festival of Legends has rocked on, and on, and on. The local Grimtotem Tauren have grown tired of the racket! Now they and their leader, Magatha, have come to not just shut down the show, but to snuff out all music on Azeroth! The fate of music is in your hands.

Dual-class cards, Remixed cards, and E.T.C. himself are on the setlist for this Mini-Set of 38 all-new cards to add to your collection. Get them in Festival of Legends packs, or as a complete 72-card* Mini-Set. Get the normal version in-game for $14.99 or 2000 Gold, or get the all-Golden version for $69.99 or 10,000 Gold. The all-Golden version also comes with a bonus Diamond copy of the Magatha, Bane of Music Legendary minion!

* 4 Legendary cards, 1 Epic card (x2), 17 Rare cards (x2), and 16 Common cards (x2).


Special Event - Epic Duels of Rock Legends

Quote From Hearthstone

You’ve been challenged to an Epic Rock Duel! Will you step up to the stage? From June 6 to June 20, complete Event Quests to earn Event XP on a special event rewards track. Complete the rewards track for one Standard Pack, one March of the Lich King Pack, and one Festival of Legends Packs!


New and Returning Tavern Brawls

Quote From Hearthstone

Special Returning Tavern Brawl: The Dark Wanderer

On June 7 and June 14, we’re bringing back a special Diablo-themed Tavern Brawl! Face off against the mysterious Dark Wanderer in this epic boss battle where progression is saved after a loss and the stakes are raised each fight!* The first time you Defeat Diablo, you’ll earn a special Lilith card back!

*Progression is saved within each week’s Tavern Brawl, not across both weeks. This is one Tavern Brawl run twice in a row, not a 2-week long Tavern Brawl. Your first time defeating Diablo each week will grant you one Standard Pack.

New Tavern Brawl: Battle of the Bands

On June 21, with a second encore performance on June 28, we’re running a new, special dungeon-run style Tavern Brawl! You play as a fan turned musician, trying to win their way onto the main stage! Face off against 7 randomized musical acts on your way to the final battle against E.T.C. himself.

Each week, you get one Standard pack for your first win and one Festival of Legends pack for your first full clear.

Bug Fixes & Game Improvements

Quote From Hearthstone

  • [Hearthstone] Photographer Fizzle’s Snapshot will now grant cards when recast by cards like Grand Magister Rommath.

  • [Battlegrounds] Lord Barov has been temporarily removed from the Hero Pool due to a bug; he will be returned to the Hero Pool in an upcoming hotfix patch.

  • [Progression] Fixed a bug blocking loaner deck grants for some new/returning players.
