A Halloween event will be taking place in Hearthstone from October 24 through until November 6 and will change the game’s look as well as add a few features to make it all much more spooky.
Everyone will be getting a free card pack and Arena Runs. A Whispers of the Old Gods card pack will be given out from 9 am PDT on October 24 until October 30 at 11:59 pm and a Knights of the Frozen Throne pack will be available from 12:01 am PDT on October 31 until 11:59 pm PDT on November 5.
A new Dual Class Arena will also be added, allowing players to choose a Hero, choose a Hero Power from some other class, and pick cards from both of those Hero’s decks. Your Hero will also be dressed up in Halloween costumes for the Dual Class Arena battles. A special Tavern Brawl will run from October 25 through the 28, and will be given and “costume,” or a deck of cards made from cards of various Heroes. Your costume will also give you the a passive Hero Power.
Finally, a new Hero is being added. Nemsy Necrofizzle is a Warlock Hero that you can earn by playing in a Fireside Brawl. Nemsy will be available past the end of the Hallow’s End event.
