As rumoured, the next Adventure Mode expansion for Hearthstone: Heroes of Warcraft is set Blackrock Mountain.

According to Blizzard, Blackrock Mountain will introduce a slew of new hot-headed bosses to put players’ duelling skills to the test.

“The Blackrock Mountain Adventure thrusts Hearthstone players into the middle of a war between powerful forces battling for control of the mountain,” it said.

“There, duellists will encounter fierce minions, including Dark Iron dwarves, fire elementals, and dragons, before facing off against iconic menaces from the Warcraft universe, such as Ragnaros, the Firelord.”

Those who take down these villains will be rewarded with 31 new cards inspired by the legendary mountain and its denizens, bringing a wealth of new tactical options to the ever-evolving Hearthstone metagame.

One wing of Blackrock Mountain will open up each week of April (for a total of five), and as was the case with Curse of Naxxramas, each will be for either 700 in-game gold or AU$7, with the entire Adventure purchasable for NZ$25.

The expansion will be available on PC, Windows and Android tablets, and iPad.
