Hearthstone 21.4 Patch Notes – October 12, 2021

Quite the Roster

Mercenaries is launching with 51 playable Mercenaries! We’ve compiled a list of all Mercenaries who will be playable at launch, as well as all their Abilities and Equipment. The Card Library will hold all this information in a future update. On top of the stats shown here, every Mercenary gets an additional +1/+5 when you fully max them out at level 30, with max Abilities and Equipment.

Keep in mind, this is just a snapshot of all the Mercenaries as they will exist at the launch of Hearthstone Mercenaries. We plan to cover future updates in patch notes and other blog posts, and in the Card Library once it’s been updated.

A Village Comes to the Tavern

With the addition of Mercenaries comes a new way to interact with Hearthstone, in the Mercenaries Village. The Village is the jumping off point for all things Mercenaries, including managing your collection in the Tavern, setting off on Bounties, jumping into the Fighting Pit, and more! You can also upgrade the buildings in your Village as you play, to upgrade their functionality or make them more efficient.

Some upgrades are free, unlocked through gameplay, while others cost Gold. At launch, it will cost 900 Gold to fully upgrade your Village: 100 to unlock the Fighting Pit, 200 to upgrade the Travel Point (which unlocks Heroic difficulty for Bounties), 200 to upgrade the Campfire (to add a slot to the Task Board), and another 400 to upgrade the Campfire a second time (to add another slot to the Task Board).

Mercenaries Matchmaking and Rating System

The Mercenaries Fighting Pit will have its own, new matchmaking and rating system. This new system is the most complex matchmaking and rating system Hearthstone has ever seen, to account for all the variables in each Mercenaries matchup. And if the perfect match can’t be found, we’ll make one for you with new A.I. opponent technology! Look for an article highlighting and further explaining the new system, soon.

Spooky Season is Nearly Here


Preparations for Hallow’s End begin in patch 21.4, with festive box dressing and fun, costumed cosmetic options coming next week. The Fairy Tales Bundle includes fairy tales-themed hero skins for Rexxar, Jaina, Thrall, and Anduin. The Battlegrounds Bundle – Hallow’s End includes a Gala Medivh alternate Bartender and seven costumed hero skins. After you’ve gotten your costume picked out, the festivities will kick off in patch 21.6 (details coming closer to that patch).
