During a Twitch livestream on July 6^th, Game Director Ben Brode and Production Director Jason Chayes announced Hearthstone’s newest upcoming expansion, Knights of the Frozen Throne. Fans of World of Warcraft will immediately remember this as an iconic raid featuring the Lich King himself.

In the announcement video, Blizzard announced some new cards and mechanics. The major one being the fourth card type, hero cards. The current card types are minions, spells and weapons. The hero card is something that works much like the card Lord Jaraxxus. The hero that you have chosen to play will be replaced with an undead version of themselves to fit the whole Death Knight theme of the raid. You will also get some armor, a new hero power and in Rexxar’s case, a battlecry. Here’s the hero card they showed off.

The other new mechanic that they showed off is called Lifesteal. Whenever a minion or spell does damage with the keyword Lifesteal on it, you will heal for the amount of damage done in that instance. Here’s the two Lifesteal cards they showed off.

The full expansion will feature 135 new cards, 8 free boss fights for everyone to partake in and a unique hero card for every class. After playing through the prologue, every player will get one of the hero cards given to them at random for free, so everybody gets a fair chance.

There will be more cards revealed on July 24^th and the expansion will be available to all in August, no specific date has been given. You can also pre-order 50 packs of this expansion for $49.99 and you can get a bonus Frostmourne cardback.
