With the new mid-set for The Madness at the Darkmoon Faire expansion on the horizon, Hearthstone received its corresponding patch notes for the 19.4 update ahead of time today.

The Darkmoon Races mini-set is coming on Jan. 21, the same day as Patch 19.4. Aside from the 35 new cards being added to Constructed Ladder, there are multiple updates to both the Battlegrounds and Duels mode.

Here are all the important takeaways from the 19.4 patch notes.


The Battlegrounds update brings two new heroes into the mix: Tickatus and Greybough. It’s unknown if Tickatus’ Hero Power means he’ll be gaining extra Darkmoon Prizes every four turns or if his inclusion will remove the new spell feature. Greybough gives extra combat stats and Taunt to minions summoned during combat. This ability synergizes well with Beast, Mechs, and Demons in the pool since those types regularly summon multiple tokens in the middle of the combat stage of Battlegrounds.

The new heroes will be available for all players who don’t have the battle pass on Feb. 4.

The patch also brings changes to the Demon archetype by adding two new Demons into the mix and removing Floating Watcher from the Battlegrounds Minion pool. This pushes Demons further away from the usual self-harm archetype without removing the strategy completely.

Here are the exact notes for the balance updates and the new content for Battlegrounds:

New Heroes


  • Prize Wall [Passive]
  • Every four turns, Discover a Darkmoon Prize.


  • Sprout It Out! [Passive]
  • Give +1/+2 and Taunt to minions you summon during combat.

Duels is receiving a mid-season update with Patch 19.4. All ratings will be reset in Casual and Heroic and the new Darkmoon Races mini-set will be added to the eligible cards you can use to build your starting deck.

In addition to these changes, every class will be receiving access to one new Hero Power and three new Signature treasures, with one of the three being a Dual-Class card. In addition to the new starting content, there will be four new Passive Treasures and two new Active Treasures to be found in the middle of your matches.
