Bug Fixes & Game Improvements

  • Fixed a Battlegrounds bug where Argent Braggart would not retain stat buffs when tripled.
  • Fixed a bug where Malevolent Strike would not discount itself when created by Deck of Lunacy.
  • Fixed a bug where losing control of a minion immediately when it comes into play (such as playing Silas Darkmoon on an empty board) would not correctly Corrupt cards in hand.
  • Fixed a bug where the ‘created by’ tag on generated cards was showing up as ‘UNKNOWN ENTITY’ when played.
  • Fixed a bug where Glinda Crowskin would not grant Echo to cards modified by Deck of Chaos.
  • Fixed a visual bug where transforming a Dormant minion could make it appear to retain buffs while Dormant.
  • Fixed a visual bug where Corrupted minions appeared to respawn on the board after being destroyed.
  • Fixed a visual bug where viewing progress for quests such as Open the Waygate would no longer highlight cards in hand that did not start in your deck.
  • Fixed a visual bug where Zombeasts in play only displayed card text for the first beast selection when using the Build-A-Beast Hero Power.
  • Passive Treasures offered between matches in Duels should now present more options that are better suited for the class you’re playing.

Coming February 2 – Book of Heroes Anduin


Raised with the expectation he would follow in his father’s footsteps, Prince Anduin has instead forged his own way through the grace of the Light. He learned to wield holy magic as well as a sword, making him a unique figure among the royalty of Azeroth. Thus armed, Anduin has embarked on numerous adventures as far away as the storied realm of Pandaria and as close as the decaying ruins of Lordaeron.

Follow Anduin’s journey in the next installment of Hearthstone Book of Heroes, releasing on February 2! Defeating all 8 bosses in this linear adventure will reward 1 Priest Pack, containing only Priest cards from Standard!

    Wait, does Tickatus gain 2 Prizes every 4 turns? Or are Prizes getting removed outside of Tickatus?
