One Night in Karazhan is the fourth adventure in Hearthstone. The adventure includes 13 bosses divided among four wings (plus a free introductory encounter), a more difficult Heroic mode, and 9 Class Challenges. It introduces 45 new collectible cards, a new battlefield, and two new card backs. One Night in Karazhan takes players back to the golden era of the mystical tower of Karazhan, when a young Medivh was not only Azeroth’s Guardian but also its most sought-after bachelor. After gaining widespread admiration for thwarting the devious plans of Arch-Thief Rafaam, winning the Grand Tournament, and resisting the calls of the Old Gods, the player is invited to a once-in-a-lifetime magical party destined to be remembered for ages. But upon arrival, Medivh is nowhere to be found, and the tower’s enchantments have gone wild, turning harmless pranks into life-threatening hazards. It’s up to the player to locate Medivh, bring peace back to the chaotic tower, and save the night—just in time for the big event.
Karazhan, long a powerful hub of arcane energy, is about to become the center of an entirely new kind of cosmic phenomenon. The wizard Medivh has poured every ounce of his magical prowess into hosting the most extravagant and opulent party ever conceived, and your name is etched on the guest list among Azeroth’s elite and beyond! With such a diverse and fascinating array of guests, this celebration is destined to be truly out of this world. But as you dance to the music and let the dazzling sights take you in, be cautious; one night in Karazhan can bring even the toughest down. Keep your cards close, your mind alert, and most importantly, stay alive!
