Book of Mercenaries

Book of Mercenaries is a single-player game mode first released on April 6, 2021.

It uses a classic linear adventure format with an appearance similar to Dungeon Run screen. Like Book of Heroes, Book of Mercenaries is about telling the journeys and stories, but the main characters are mercenaries, who were first introduced in Forged in the Barrens as legendary cards and unique to Hearthstone.

Like Book of Heroes, Book of Mercenaries will feature a chapter for each of the ten current classes, for a total of 80 missions or bosses. It is completely free to play and available to everyone. Additionally, completing a class's story rewards the player a corresponding class pack.

Warrior was the first class and Rokara's story was the first story to be introduced. New missions will be released over the course of the coming months.

Structure

For general information on adventures, see Adventure.

• Book of Mercenaries comprises 80 boss encounters in total.
  • The encounters are split into 10 class' stories, making each consist of 8 encounters.
• The player is given pre-made deck for each boss encounter, controls a special hero with their corresponding Hero Power, and gets special interactions between their hero and boss.
• During a class' story, the player must encounter the bosses in order and cannot choose the specific ones.
  • However, if the player loses an encounter, the player can try again without being reset to the first encounter, unlike Dungeon Run or similar modes.
    • The player can press the "Retire" button, which is under the player's hero portrait, to be reset willingly.
