Released in 2016 by Blizzard Entertainment, One Night in Karazhan is the fourth adventure expansion for Hearthstone, available on PC, Mac, iOS, and Android. Set in the legendary tower of Karazhan during the heyday of a young Medivh — Guardian of Azeroth — the expansion frames its content around a grand party gone wrong. Medivh goes missing, and the tower's magical enchantments spiral out of control, transforming festive illusions into dangerous threats. The adventure is structured across four purchasable wings plus a free introductory encounter, presenting 13 bosses in total. A Heroic difficulty mode offers a stiffer challenge, and nine Class Challenges provide additional tactical tests. Completing the content unlocks 45 new collectible cards, expanding deck-building options across Hearthstone's card pool. The expansion also introduces a new battlefield and two new card backs, rounding out its cosmetic additions.
Karazhan, long a potent nexus of arcane energies, is about to become the focal point of a very different kind of cosmic force. The wizard Medivh has used every bit of magic at his disposal to set up the most lavish and extravagant party of all time, and your name is on the guest list alongside the crème de la crème of Azeroth and beyond! With such an eclectic mix of attendees, it’s guaranteed that this party will be out of this world. But as you groove to the music and let the sights dazzle you, beware; one night in Karazhan, and even tough guys tumble. Keep your decks straight, your wits sharp, and above all, stay alive!
