Blizzard announced a big new Hearthstone expansion today titled 'Knights of the Frozen Throne.' As the title suggests, players will venture into Nortrend to face off against one of Warcraft's most famous characters, the Lich King. The new expansion adds a bunch of new content including a new class of Hero cards, a new Lifesteal mechanic, and a new single player campaign against the Lich King himself.
As customary in Hearthstone, directors Ben Brode and Jason Chayes appeared on video to announce the new Knights of the Frozen Throne expansion. As part of the Lich King lore, much of the new expansion has to do with death, or "undeath" rather. That's why Blizzard introduces the new legendary Hero Cards which give bonuses to the nine existing classes with what Blizzard calls "the essence of undeath." Or in more practical terms, gives them modified hero powers by turning them into Death Knights.
Hero cards cost mana and when played takes the place of your existing heroes. These new cards come with battlecrys, armor bonuses, and change your hero powers in new, death-themed ways.
There's also a new power called Lifesteal which returns health based on the damage you inflict. It's a mechanic similar to those found in a lot of other card games, which Chayes draws attention to in the announcement video. Combined with the new Hero Cards, Hearthstone just added a couple more mechanics that will change up some strategies presumably.
Brodes and Chayes also detailed the new single player content which will be free. These missions include a prologue, two wings of bosses (three bosses per wing), and a final battle against the Lich King. Completing the prologue will net the player one random legendary Hero Card that will transform their heroes into "a class-specific Death Knight."
You'll also be able to earn a Knights of the Frozen Throne card pack for each wing of bosses you defeat, along with an additional pack for defeating the Lich King and claiming the Frozen Throne.
The new expansion will properly rollout in August, alongside the changes Blizzard already announced about the new way Legendary Cards will drop in future packs. Players can pre-purchase Knights of the Frozen Throne bundle for 50 card packs at a one-time price of $49.99. Pre-orders include a new "chilly" card back as well.
