Hearthstone’s next adventure is One Night in Karazhan

As many guessed, Hearthstone’s next adventure will take place in Karazhan, the magical tower that also serves as a raid in World of Warcraft.

The adventure is One Night in Karazhan, and it adds 45 new cards to Blizzard’s popular, free-to-play game. The first wing will release on August 11, with additional ones coming out each following week for a month. Hearthstone is the leader in the $1.2 billion digital card game market, making over $20 million a month. It’s available on PC, iOS, and Android. Hearthstone is also one of the most popular games in the esports market. According tor research firm Newzoo, Hearthstone was the fourth most-watched esport on Twitch in June, making it one of the leaders in what research firm SuperData estimates will be a $1.23 billion market by 2019.

Hearthstone content comes in two forms: expansions and adventures. Expansions add more cards than adventures, but the latter also gives players story-driven, single-player content. This is the fourth adventure released for Hearthstone, following Curse of Naxxramas, Blackrock Mountain, and League of Explorers. It’ll also be the first new batch of cards released for the game since the expansion Whispers of the Old Gods came out came out in April.

The single-player content will give players something fun to mess around with, but the cards are the most important part of the package. New cards can change strategies and freshen up Hearthstone across all of its modes, which will help keep its player-base engaged, happy, and more likely to spend money in the future. This is especially important for Hearthstone’s most hardcore players. They often play the game daily, and they can get tired of seeing the same decks and cards over and over. This adventure will liven things up.

You can buy access to all of One Night in Karazhan for $20, or you can buy each wing separately for $7 or 700 gold (an in-game currency). If you spend real money on one wing, the other ones will become available at a discount price. Blizzard will also release a free prologue mission that will allow all players to earn two of Karazhan’s new cards.

Karazhan was home to Medivh, one of the most powerful sorcerers in the Warcraft universe. Since his absence, the tower has become home to all sorts of strange, paranormal, and magical activity. It was one of the most popular raids in World of Warcraft because of its unique setting and creative bosses, including a human-sized game of chess and a theater that turned classics like “Little Red Riding Hood” into challenging battles. Both of these moments and more will appear in the adventure.

“One Night in Karazhan will give players the chance to party with Medivh while earning some great new cards for their collections,” said Mike Morhaime, chief executive officer and co-founder of Blizzard Entertainment, in a press release sent to GamesBeat. “We’re excited to reimagine one of Azeroth’s most beloved locations in Hearthstone, and we can’t wait to see players put their new decks to the test.”

The new cards will also be added to Arena mode once they become available. Arena is a mode in Hearthstone that has players draft decks from random card choices.
