Boss

Bosses are unique computer-controlled heroes encountered in adventures. The tutorial bosses encountered in the tutorial are also bosses, but function slightly differently.

Each boss presents a unique encounter, featuring their own hero power and decks. Bosses use a combination of regular cards and boss cards, special and often extremely powerful cards not available to players. Bosses can be encountered in Normal or Heroic mode, and defeating a Heroic boss usually presents quite a challenge, with players needing to devise special decks to counter the mechanics of that specific fight.

Bosses represent well-known characters from Warcraft lore, with their hero powers and cards in keeping with their personalities. Boss battles also feature dialogue, involving the boss as well as other characters.

For a list of all bosses currently in the game, see Blackrock Mountain, Curse of Naxxramas and Tutorial.

Boss battles

Boss battles are regular matches, but with a few specific differences.

Boss battles are generally designed to offer a specific challenge, usually featuring a strong theme or style, forcing the player to find a way to defeat them. Players often must alter their decks or construct new ones in order to beat specific bosses, with each having its own strengths and weaknesses.

Boss encounters may feature multiple phases. In these battles, specific events will trigger transition into the next phase, usually accompanied by special dialogue, and resulting in the boss gaining a new hero power, new minions on the board, and/or adjustments to Health or Armor.

Similarly, while most boss encounters feature only one boss, some feature more, with specific events (usually the defeat of the current boss) causing them to be replaced by a new one. In this case all bosses must be defeated in order to complete the encounter.

Almost all boss battles have the player going first, and the boss second. This means that the boss will generally get The Coin. One exception is Patchwerk from Curse of Naxxramas.

Unlike other modes of play, boss battles do not feature a turn timer. This allows the player to take as long as they like to assess the situation each turn and decide the best course of action.

Certain boss encounters may feature special limitations, such as the Heroic Loatheb encounter, during which it is not permitted to use Alexstrasza. These limitations are not announced, but attempting to use the restricted cards during the encounter will see the minion or spell destroyed or countered, with no mana refund offered, accompanied by a little gloating from the adventure's host.

Each boss encounter features its own dialogue, which may involve the boss as well as other characters. Bosses have a number of quotes which are elicited by certain events, such as the start of the battle, the use of a certain card, player emotes, or the defeat of the boss. For a list of boss dialogue, see individual boss pages, e.g., Noth the Plaguebringer.

Normal and Heroic

Bosses found in adventures can be fought in Normal or Heroic mode. Heroic mode bosses usually feature more powerful hero powers, as well as more Health. They may also use slightly different decks, as well as improved versions of boss cards.

While Normal mode bosses typically offer minimal resistance, Heroic mode bosses are designed to provide a substantial challenge. Heroic bosses usually require several attempts to defeat by even experienced players, and generally require the construction of new and specific decks in order to counter the boss' unique abilities and style. Heroic bosses are therefore designed to offer a challenge not only in play, but in deck construction.

Decks

Each boss features a unique selection of cards. Bosses may use regular collectible cards, but also have access to unique boss cards, special and often extremely powerful cards which are not available to players. Bosses themselves do not belong to classes, but may use cards belonging to any class, as well as neutral cards. This can produce some interesting card combinations, such as Hunter's Mark and Mortal Coil. Boss decks feature 30 cards in total, but like Arena decks are not subject to the 2-copies-per-card limit found in constructed play, often featuring as many as 6 copies of certain cards.

Hero powers

Auto-cast hero powers are indicated by a golden circle around the icon

Boss hero powers vary in cost, and may be auto-cast, indicated by a special ongoing visual effect around the hero power on the playfield. Auto-cast boss hero powers are activated automatically at the start of the boss' turn when possible, following any triggered effects. This means that the boss is not able to choose the best time to make use of the hero power, or to forgo using it on any given turn. Auto-cast boss hero powers usually have a mana cost of 0, but may cost more.

Examples

Tutorial bosses

Tutorial bosses are slightly different from adventure bosses. As the fights are very specifically scripted, it is assumed these heroes do not have full decks, but rather a small selection of cards, which are always drawn in the same order. Not all tutorial bosses have hero powers.

Boss cards

Boss cards are special cards used by bosses which are not available to players. Boss cards may be unique to a single boss, or be used by several.

Free from the constraints of the balancing required for playable cards, boss cards often feature outlandish powers and effects.

Examples

Notes

While a number of bosses are also featured as playable minion cards, there is no connection between the heroes and the minion cards. Currently all tutorial bosses feature as minion cards, along with 4 of the 15 Curse of Naxxramas bosses.
