Hearthstone: One night in Karazhan is another expansion to Hearthstone: Heroes of Warcraft card game for PC, iOS and AND, created by Blizzard Entertainment studio. This add-on introduces new adventure, in which we take part in a great party of wizard Medvih. It is divided into 5 parts: The Prologue, The Parlor, The Opera, The Menagerie and The Spire. The first one is available for free, while the access to other four is gained after spending real-life money (microtransacations) or in-game currency in form of gold. We will meet well-known characters from the world of Warcraft (like seneschal Morios), against who we can obviously duel. All of this to find the host, who disappeared right at the beginning of the party.
