The 45-card set will be Hearthstone's fourth adventure, with the cards released over a four week period. As with the previous adventures, players will go through a series of battles against AI bosses in unique environments in order to unlock the cards each week.
The adventure is set before the classic World of Warcraft Karazhan raid, and before the events of the recent Warcraft movie. Much like League of Explorers, the content is an original creation based on World of Warcraft lore. There are thirteen bosses in total across the wings.
The first cards will be released just days before the European Hearthstone Championship Tour preliminaries, but the cards will be not be used in the event.
Seven cards have already been revealed, including a one mana 2/2 beast druid minion, Enchanted Raven, that Blizzard clearly hopes will finally make Beast Druid a viable deck moving forward.
Another card that has a lot of players excited is Firelands Portal. The seven mana spell deals five damage as well as summoning a five mana minion, potentially giving incredible board control and value.
Those two cards will be given to all players for free in the prologue wing. The four subsequent wings will be $6.99, or $19.99 for all four wings. Each wing can also be bought for 700 in-game gold.
