Players will also be able to obtain special Emotes that they can equip over the base emotes in their Battlegrounds Collection. The first set of Battlegrounds Emotes – Mystery Mayhem, will be a collection of Nathria and murder-mystery themed emotes that will be available one week after the expansion goes live!

Two new event Tasks can be unlocked on each of the first five days of the event, but you have until September 6 to complete all 10 Tasks. Completing all 10 Tasks will get you the C’Thun Mercenary, a random Golden C’Thun Portrait, the Diamond C’Thun Portrait, and 700 Mercenary Coins!

Merc Updates

Brann Bronzebeard

  • Summit Campfire 5
    • Old: Gain +4 Frost Resistance. Your characters deal Critical Damage to enemies whom have already acted. → New: Gain +5 Frost Resistance. This turn, enemies who have acted take Critical Damage.
    • Dev Comment: In addition to being reworded and giving +1 more Frost Resistance, Summit Campfire has had some bugs addressed that prevented its full effect from working. Now, when the effect triggers, enemies who have already acted will take Critical Damage and any enemies who act after this effect goes will take Critical Damage for the rest of the turn; if Brann dies, all enemies already impacted will stay impacted, but no additional enemies will be afflicted.
  • Extra Spirit 4
    • Old: Passive: If you have them in play, Elise and Reno have +5/+12. → New: Passive: Your Explorers have +5/+12.

  • Dev Comment: Brightwing’s fantasy of swapping between bench and battlefield struggled because of randomness. We decided to strengthen her kit overall and reduce the randomness in it so players could direct her effects and choose what she swaps with.
  • Old: 7/77 Maxed Stats → New: 8/88 Maxed Stats
  • Faerie Breath 5
    • Old: Deal 10 damage. Give a random friendly Merc on your bench +3/+5. → New: Deal 12 damage. Give the lowest health Merc on your bench +3/+10.

    • Old:  Faerie Breath gives an additional +5 Health. → New: Battlecry: Give your lowest health Merc on your Bench +15 Health.

Lady Anacondra

  • Dev Comment: Lady Anacondra always felt like a Merc that needed her Equipment just to get her Abilities to baseline levels. So we baked two of the Equipment effects into her Abilities and updated those Equipment with new Viper-summoning effects so that more players can experience that part of her kit.
  • Old: 8/76 Maxed Stats → New: 9/84 Maxed Stats
  • Serpent’s Bite 5
    • Old: Deal 6 damage. At the end of this turn, it takes 6 damage. → New: Deal 12 damage. At the end of this turn, it takes 12 damage.
  • Mend Beast 5
    • Old: Restore 15 Health to a character. If it’s a Beast, also give it +15 Health. → New: Restore 15 Health to a character and this Merc. If it’s a Beast, also give it +15 Health.

Morgl the Oracle

  • Dev Comment: Morgle always wanted to be the healer for the Murloc party, but unfortunately other characters provided more value. We’ve redesigned his healing to give him the tools to be the Murloc healer he always wanted to be.
  • Old: 9/83 Maxed Stats → New: 10/93 Maxed Stats
  • Murloc Missile 5
    • Old: Deal 10 damage. Give your Murlocs +5 Health. → New: Deal 14 damage. Give your Murlocs +6 Health.

  • Dousing Rod 4
    • Old: Healing Wave restores 10 more Health. → New: Passive: After one of your Murlocs takes 20 or more damage in a single hit, restore 8 Health to it.

Guff Runetotem

  • Dev Comments: Guff always relied on Bramblethorn Totem to keep Living Brambles’ damage up. We built that damage into Living Brambles to give him more Equipment options, including a new option as a backline character with the Bramblethorn Totem rework.
  • Old: 10/80 Maxed Stats → New: 12/91 Maxed Stats
  • Living Brambles 5
    • Old: Deal 10 damage. Nature Combo: Repeat this. → New: Deal 14 damage. Nature Combo: Repeat this.

Garrosh Hellscream

  • Mak’Gora 5
    • Old: Attack an enemy. It Attacks this Merc back. → New: Take 5 less damage this turn. Attack an enemy. It Attacks back.
    • Additionally, Mak’Gora is now Speed 5 at all levels.

  • Frostbite is now Speed 5 at all levels.

Cookie, the Cook

  • Cookie’s Cooking 5
    • Old: Bleed (5) to all enemies. Restore 5 Health to friendly Murlocs and Pirates. → New: Bleed (10) to all enemies. Restore 10 Health to friendly Murlocs and Pirates.
    • Dev Comment: Cookie was the first playable Merc that we designed with the Bleed effect. At the time, we thought it would be a good idea to allow Bleed to scale with Spell Damage. We’ve decided that Bleed shouldn’t be increased by Spell Damage buffs, so we’ve adjusted the base power of the Ability to compensate for that change.

Zar’jira, the Sea Witch

  • Old: 8/77 Maxed Stats → New: 9/86 Maxed Stats
  • Upstart Acolyte 4
    • Old: Passive: +20 Health. Whenever a friendly character is Frozen, Freeze a random enemy. → New: Passive: +20 Health. The first time a friendly character is Frozen each turn, Freeze a random enemy.


  • Dev Comment: Uther has always struggled to find a place on the Holy team focusing on Anduin and Velen. We think this is a flavorful change and we hope this change will bring more role diversity to Holy compositions. Uther now has the distinction of being the first Protector to deal Holy damage. For justice!
  • Old: Caster → New: Protector
  • Old: 11/82 Maxed Stats → New: 12/91 Maxed Stats
  • Hammer of Justice 5
    • Old: Deal 12 damage to a character. Its next ability is (3) Speed slower. → New: Deal 15 damage to an enemy. Its next ability is (3) Speed slower.

  • Old: 9/69 Maxed Stats → New: 10/75 Maxed Stats


  • Old: 6/73 Maxed Stats → New: 7/76 Maxed Stats

Vanessa Van Cleef

  • Dev Comment: Originally, the fantasy of Vanessa was that she’d steal a bunch of attack and then get a big payoff with Makeshift Weaponry. In practice, however, spending all your Stolen Attack was too high a cost. It also meant that Makeshift Weaponry was a dead Ability on her first turn. We’ve increased its base power, reworked the Extra Pockets synergy, and made the downside less punishing, so we increased the speed to 7 to compensate for those buffs.
  • Old: 13/75 Maxed Stats → New: 13/86 Maxed Stats
  • Makeshift Weaponry 5
    • Old: Speed 3. Spend Stolen Attack to deal that much damage to all enemies. → New: Speed 7. Deal 12 damage to all enemies. (Improved by Stolen Attack)
  • Extra Pockets 4
    • Old: After using Makeshift Weaponry, this Merc keeps up to 10 Attack. → New: Battlecry: Steal 4 attack from an enemy opposite this.


  • Old: 10/80 Maxed Stats → New: 10/87 Maxed Stats


  • Old: 13/83 Maxed Stats → New: 13/86 Maxed Stats


  • Old: 12/90 Maxed Stats →  New: 14/94 Maxed Stats


  • Old: 10/70 Maxed Stats → New: 11/75 Maxed Stats
  • Broodmother’s Rage 4
    • Old: Passive: When another friendly Dragon is destroyed, deal 7 damage to all enemies. → New: Passive: When another friendly Dragon is destroyed, deal 7 Fire damage to all enemies.
    • Dev Comment: This Equipment was already dealing Fire damage, so this is just a wording update to clarify the effect.

Lady Vashj

  • Old: 10/75 Maxed Stats → New: 12/81 Maxed Stats

Captain Hooktusk

  • Old: 10/75 Maxed Stats → New: 13/83 Maxed Stats

Trigore the Lasher

  • Backlash 5
    • Old: Gain +5 Attack. Each time an enemy damages an adjacent ally this turn, deal this Merc’s Attack damage to them. →  New: Gain +5 Attack. After an enemy damage an adjacent ally this turn, deal this Merc’s Attack damage to them.
    • Dev Comment: This is not a functional change to Trigore, just a wording update. We also fixed a bug so that Trigore no longer hits after Trigore is functionally dead and no longer hits enemies who are functionally dead.


  • Old: 11/79 Maxed Stats →  New: 11/80 Maxed Stats
  • Marching Murlocs (Summoned by the March of the Murlocs Equipment)
    • Old: Speed 5 → New: Speed 4
