23.6 Patch Notes

23.6 Patch Notes

Patch 23.6, launching today, sets the stage for Murder at Castle Nathria, Hearthstone’s next expansion! The patch also includes updates to Battlegrounds, Mercenaries, Arena, and more.

Pre-Purchase Murder at Castle Nathria

Hearthstone’s next expansion, Murder at Castle Nathria, is coming on August 2! This anima-Infused mystery takes place in the Shadowlands, where murder is most foul. It’s up to you, and the great detective Murloc Holmes, to scour new Location cards for clues as to which of the 10 suspects killed the great Sire Denathrius!

Murder at Castle Nathria includes 135 new cards surrounding the murder mystery and the 10 guests at the center of it. You can learn more in the Murder at Castle Nathria Announcement blog. Two pre-purchase options are available now to kickstart your inquiry once the expansion launches.


Log in and Get Prince Renathal for Free

Add him to your collection and see what you can do when you have more space to work with.

Mercenaries Updates

Login Now to Get Three Free Portraits!

Any player who has completed the Mercenaries tutorial* will receive special Portraits for Tyrande Whisperwind, Millhouse Manastorm, and Xyrella! These Portraits are a thank you to everyone who has tried out Mercenaries since its launch. We know that you’ve all been eagerly waiting to see what major changes we’ve been working on this year, including what you’ll be able to do with your excess coins.

Later this year, we’ll be adding a system that will let you exchange some of your excess coins for random coins for a Merc you own but haven’t yet Maxed. We’re also still working on the end-game content that was hinted to in the Year of the Hydra announcement, including a way to use excess coins to add power and personalized traits to your Maxed Mercs, all of which we still expect a bit further down the line.

It has taken us a little longer than we’d hoped to implement these systems, but we wanted to let you know we have a clear plan on our goals for these projects, we are actively working on them, and they are coming. We consider this to be our highest priority in Mercenaries development; we just need some more time to make sure it’s done correctly.

* This is a one-time award for accounts that have already completed the Mercenaries tutorial when Patch 23.6 launches. Those players will automatically have these portraits added to their Collection. These Portraits may become available to other players through other means at a later time.

New Limited-Time Event: Yogg-Saron

The Old Gods continue their onslaught as Yogg-Saron turns its many maws towards Mercenaries. You will be able to take on MADNESS itself in this limited-time event, starting on June 30. The event will consist of 10 special Tasks centered around the Old God Yogg-Saron. Two new event Tasks can be unlocked on each of the first five days of the event, but you have until July 15 to complete all 10 Tasks. Completing all 10 Tasks will get you the Yogg-Saron Mercenary, a random Golden Yogg-Saron Portrait, the Diamond Yogg-Saron Portrait, and 700 Mercenary Coins! Naga, Casters, and a couple of Night Elves will be integral in this battle.

Complete all seven Quests to earn a Standard Packs, a Card Pack for each of Fractured at Alterac Valley, Voyage to the Sunken City, and Murder at Castle Nathria, a Mercenaries Pack, a Battlegrounds hero skin, and a Warrior hero skin.

New Features—Expanded Recent Players List and In-Game Reporting

Recent players capabilities have been expanded and improved in the friends list. Now, there will be a dedicated section at the top of your friends list that includes last opponent, former friends, new friends, your current opponent, and more.

Additionally, we’re happy to share that player-reporting will soon be added to the in-game friends list menu! You’ll be able to report players from the recent players list (including your current opponent) or from your friends list. Grounds for reporting will include inappropriate names, inappropriate chats, and inappropriate gameplay. We’re putting the finishing touches on this feature, so you’ll see hints of it in the game with this patch, and it’ll become available soon!
