Battlegrounds Updates


Varden Dawngrasp

  • Twice as Nice
    • Passive.  After Bob’s Tavern is Refreshed, copy and Freeze one of his minions.



  • Glory of Combat
    • Passive. After a friendly minion kills an enemy, give it +1 Attack permanently.



  • Broodmother
    • Passive. Avenge (4): Summon a 2/1 Whelp. It attacks immediately.


Players with Battlegrounds Perks will have early access to the three new Heroes before they are formally released on March 1.


  • Kael'thas, Silas Darkmoon, and Chenvaala have been returned to the Hero Pool.


Snow Elemental (Chenvaala’s Buddy)

  • Old: [Tavern Tier 2] New: [Tavern Tier 3]


Varden’s Aquarrior (Varden Dawngrasp’s Buddy)

  • [Tier 2, Elemental] 3 Attack, 5 Health. “Twice as Nice” also gives the copy stats equal to your Tavern Tier.


Icesnarl the Mighty (Rokara’s Buddy)

Many Whelps (Onyxia’s Buddy)

Bob is back with another way to add flair and personalization to the Tavern: Battlegrounds Finishers! Battlegrounds Finishers are animations that replace the default Attack animation whenever your Hero wins a round of combat.* Bob’s first Finisher, Astral Impact, is a two-stage Finisher. That means that it shows a special animation whenever your Hero wins a round and then an even bigger animation when you deal 15 or more damage to your enemy! Keep a look out for more cool Battlegrounds Finishers in the future.


In addition to the first-ever Finisher, Bob’s also bringing two new Battlegrounds Boards to choose from. On February 14, at 1 p.m. Pacific, join ninaisnoob on her YouTube channel for interviews with Cosmetics Production Lead Alicia Cornelia and Features Lead Chadd Nervig about Battlegrounds Finishers and the new boards! The Jade Gardens Battlegrounds Board, pictured above, will be available as soon as the patch launches. All other new Battlegrounds cosmetics, including the Astral Impact Finisher and the Cosmic Study Battlegrounds Board below, will become available starting on February 22.


* Battlegrounds Finishers are equipped globally, so any Hero you use will use your equipped Finisher whenever you win a round of combat. Both players will be able to see the winning player’s Finisher at the end of any round of combat.

Book of Mercenaries—Bru’kan


The shaman Bru’kan of the Darkspear clan has done his best to prepare the young Horde mercenaries for the battle ahead, but now the moment has come. The shattered naaru has reformed and its power has resurrected the vengeful warlock Tamsin Roame as a lich! Can Bru’kan tap into the elemental energies of Alterac Valley and summon Lokholar the Ice Lord to end the war and stop Tamsin? Find out when Book of Mercenaries Bru’kan launches on February 15. Defeating all 8 bosses in this linear adventure will award 1 Shaman pack, containing only Shaman cards from Standard.

Bug Fixes & Game Improvements

  • There will now be a confirmation prompt when you attempt to concede a game before you would get quest progress for that game (like “Play 3 Games” Quests and the Alterac Valley Honor Quests). We have also loosened the requirements on counting those types of Quests.
  • When playing Maestra of the Masquerade, the premium level of Hero Powers will now match the premium level of the Hero (for instance, if you have a Golden Hero, your Hero Power will now be Golden, too), making for much better disguises.
  • A duplicate uncraftable version of Shadow Bolt will no longer appear in the Collection Manager.
  • Fixed a bug where Saidan the Scarlet could still get double-buffs from his effect, even after being Silenced.
  • Fixed a bug where certain Mana Ramp cards would not grant Mana Crystals if you played Wildheart Guff and had between 10 and 20 Mana Crystals.
  • Fixed a bug where playing Paralytic Poison on Kingsbane would cause the “Immune when attacking” effect to carry over onto any other weapons equipped during the game.
  • Fixed a bug where the Daio Chan Valeera Hero Skin would block Baku the Mooneater’s effect from upgrading the player’s Hero Power.
  • Fixed a bug where Lost in the Park (Druid’s Questline) would not progress the first time that Attack is gained after equipping Sphere of Sapience.
  • Updated the priority of several Cast When Drawn cards (including Fel Rift, Bleed, and Olgra, Mankrik’s Wife) to match that of cards like Soul Shards. One result of this change is that Runed Mithril Rod will now consistently discount the next card drawn after any Cast When Drawn card that activates Rod’s effect, instead of the Cast When Drawn card itself.
  • Fixed a bug in Battlegrounds causing Baby N’Zoth and Brann Bronzebeard to give an extra activation.
  • Fixed a bug where Baby Elekk would not trigger for a same-statted minion if the same-statted minion’s stats changed when played (such as when another minion is giving an aura stat-buff for that type of minion).
  • Updated the text of all Mercenary Task 7s from “Defeat 2 Heroic Bosses” to “Complete 2 Heroic Bounties.”
  • Fixed a bug that allowed players to place Mercenaries they do not own into the Training Grounds, causing some players to get locked out of the Training Grounds.
  • Fixed a visual bug causing Mercenaries Equipment Unlocks to show as one Task earlier than the actual unlock Tasks.
  • Fixed a bug where Anduin’s Task 11 was tracking Damage instead of Healing.
  • Fixed a bug where characters with Windfury could attack through Freeze.
  • Fixed a bug where Vanessa VanCleef’s Shifting Satchels Ability was respecting Taunt even though it’s a ranged Ability.
  • The stats of Eudora’s Cannons will now show on Prepare the Cannons and Primed Armaments.
  • Fixed a bug that blocked some players from entering Duels if a previous Duels run ended prematurely.
  • Fixed a bug that sometimes blocked the win/loss record from showing in Duels and Arena.
  • Fixed a bug that sometimes changed a player’s Favorited Card Back in a Friend Challenge.
  • Fixed a bug that prevented certain Card Backs from remaining marked as Favorited after logging out.
  • The Immoveable Object has finally been moved! Fixed a bug preventing the “You Are Not Worthy” achievement from tracking progress.
  • Misc. other performance improvements, bug fixes, and visual issues.

    For the special Chi-Ji event on the 22nd are they saying that we'll have to complete the current Alterac bounties first before we can access it?...

    "As you prepare for this event to begin, make your way through all the Alterac Valley Bounties and take special care to strengthen your Beasts and Dragons, which will be essential for some of these Tasks."

      I expect so yes. It's normal for these special/story tasks to require you to complete specific bounties, and you only have access to a bounty when you have beaten all the ones before it within that zone. You won't have to do them on Heroic though, so you won't need your mercs to be super powerful to do it.

    Scabbs, Xyrella, and Bru'kan (And obviously Tamsin) aren't present within the trailer at all, not even during the scene with the heroes shadows.

    Cariel however is so we can assume she survived being pulled off the bridge.

    My bet is that our boy Bru'kan doesn't make it to Onyxia and dies defeating Tamsin, Xyrella and Scabbs might go on to save Xyrella's daughter instead of fighting against Onyxia.

      Perhaps. Or it just became too cluttered putting all 9 on the screen at once.

      Scabbs is in the trailer; he just played Cloak of Shadows.

    So... Mercenaries new heroes letting us know who the new legendary cards are? 

    • AngryShuckie's Avatar 1695 1666 Posts Joined 06/03/2019

      There's no chance of that this time. The new mercs are about as disconnected from Onyxia's Lair as any characters in Warcraft. 

      The previous batch of mercs had Wrathion and Sinestra, who would be more plausible, but still quite unlikely.

    Lol, 70 bucks for the golden miniset, that's just amazing. That's more than 4 times the price of the normal set. For some reason tears are flowing down my cheeks as I write this.

      It's 11,600 guaranteed dust, the equivalent of 116 random packs on average. I'm not sure how much cheaper you would expect it to be, but from a dust value perspective, it's a really good deal.

      Don't get me wrong -- I think golden cards are quite silly, but if someone is a golden collector, this price point is very attractive. It's also a decent investment for anyone who plans to dust all their Standard cards as they rotate out. (That's another practice I abhor, but I get why people do it.)

        People purging their collection each time we rotate cards is so tragic. The return on investment is generally garbage, and they're constantly burning a bridge one can't easily fix. I get that some people only play Standard, but still.

      Whales are going to spend, so nice of Blizzard to give them more ways to spend money.

    I still wonder how we can obtain the Hero portrait of Tavish, something at the end of the Book of Mercenaries. Or just in the next expansion track?

      My guess is it'll be in the next rewards track. We'll probably also get a fourth Kurtrus, Xyrella, and Rokara portrait on the same track, based on the new artwork we saw in Tavish's book for Kurtrus and Xyrella.

        The mercs Story should be done after this year, so putting them into the next reward track seems extremely unlikely.
