Arena Balance Update

Hearthstone update 21.0.3 updated the appearance rate of cards to ensure class balance remains close to the ideal 50% win-rate. Specifically, the win-rate of Druid, Warrior, and Demon Hunter should now be decreased. The win-rate of Mage, Priest, Rogue, and Shaman should now be increased. The win-rate of the other classes should be roughly the same as before.

Bug Fixes & Game Improvements

Updated the Stealer of Souls animation to now only trigger if the card ends up in your hand (it does not trigger for cards that are Cast When Drawn, such as Soul Shards). The animation will also no longer trigger if the drawn card already costs Health instead of Mana (such as when you have two Stealer of Souls in play).

• Fixed card text errors for Psyfiend and Florist (no functional change to either).
• Fixed a bug where Prismatic Jewel Kit would trigger when effects returned a Divine Shield minion to the owner’s hand or moved a Divine Shield minion from the owner’s hand to the owner’s deck.
• Addressed an issue where Seek Guidance (the Priest questline) would sometimes count the original Cost of cards, instead of the Cost actually paid for the card.
• Fixed a bug where the Initiate Set version of Eye Beam did not properly display card art in the Collection Manager.
• Fixed a bug where Reborn Rites, The Lich King’s Battlegrounds hero power, caused players to disconnect from the game server.
• Added interactions between Pave the Way (part of the Paladin Questline) and Duels-specific hero powers.
• Fixed various bugs in Book of Heroes Gul’dan and Book of Heroes Illidan.
• Fixed a bug where Duels achievements were not tracking properly.
• Addressed an issue where Witchwood collection achievements triggered even though the requirements were not yet met.
• Addressed an issue where completing all Book of Heroes installments would not display the proper achievement or give the proper award. All players who have already completed all 10 Book of Heroes will automatically receive the proper award of a Golden Standard pack at a later date.
