Blizzard has officially announced its next Hearthstone expansion, which will apparently be titled Journey to Un’Goro, contrary to earlier leaks. The expansion will add a total of 135 minions, spells, and other cards when it’s made available in early April.

Journey to Un’Goro is set to introduce some new gameplay concepts to the ever-expanding library of cards that Hearthstone players have to choose from. Some existing minions will be given the Elemental type, which will offer synergies with some of the new cards set to be added to the game as part of the expansion.

There’s also a new card keyword for players to contend with, Adapt. Cards with Adapt will give players three Adaptations to choose (from a pool of ten) in a mechanic that Blizzard’s announcement blog post compares to the Discover ability that’s already in the game.

The expansion will also include an entirely new type of legendary card in the form of Quests. Players can only include one Quest card in each deck, and it’s guaranteed to land in their opening hand — complete its requirements will yield “incredible rewards.”

The new game board set to be introduced with Journey to Un’Goro.

For instance, the ‘Awaken the Masters’ Quest card revealed today asks players to summon 7 minions with a Deathrattle effect. If they’re successful, they’re awarded the powerful ‘Amara, Warden of Hope’ card for use in that match.

Starting tomorrow, Hearthstone players will be able to pre-purchase 50 Journey to Un’Goro card packs for the special price of $49.99, which comes with the special fossil card back as a bonus. Blizzard hasn’t confirmed a specific release date, but did announce that the expansion would drop in early April, with card reveals getting underway on March 17.

Hearthstone is available now for PC and mobile devices.
