Class

Class is the primary determinant of a hero's powers and abilities, and the strongest factor in deck selection. While each hero represents a unique character with their own personality, portrait and sounds, their class determines their Hero Power and which class-specific cards they are able to play. While each hero belongs to only one class, there are often multiple heroes representing each class. However, all heroes of a given class function identically, using the same cards and Hero Powers.

New players start with only the mage class available, and must unlock the others through defeating them in matches in either Practice mode or Play mode. Unlocking all 9 original classes also unlocks various other game features: the Arena, adventures, and "Expert" difficulty Practice mode.

Hearthstone's classes mirror those of World of Warcraft, with the exception of Death Knight, which only exists as a few Uncollectible cards, and Monk, which is not currently represented at all.

Below is a list of the current classes, with a brief description of each class' notable mechanics. For more detailed information, see individual class pages.

At a glance

Demon Hunter

• Agile fighters who call upon demonic allies and fel magic. Outcasts of society, Demon Hunters attack with their blades and claws, using fallen allies to fuel their power. Not ones to shy away from a fight, Demon Hunters specialize in granting their hero Attack damage for one turn.

Druid

• Shapeshifting protectors of the wild, with powerful Taunt minions and adaptable Choose One effects, druids are also able to accelerate their rate of mana accumulation, allowing them to access high-mana-cost cards earlier than their opponents. Druids are a versatile class, capable of using the forces of nature and primal rage to crush their enemies or empower their allies.

Hunter

• Trackers and huntsmen, with a synergy with Beasts, a selection of bows, and a supply of cunning deadly traps, hunters never miss their mark. Whether unleashing their Beasts upon the enemy or sniping them from afar, hunters possess relentless and immediate damage capabilities.

Mage

• Masters of arcane, fire and frost, mages wield formidable single-target and area of effect damage spells, and can freeze enemies in their tracks. Mages have a strong spell-synergy, capable of turning minor incantations into devastating Fireballs, and can employ a range of magical Secrets to redirect enemy effects, protect themselves from damage, or stop the deadliest foe or spell in its tracks.

Paladin

• Stalwart champions of the Light, wielding sturdy weapons and gifting the recruits of their order with Divine Shields and a range of powerful Blessings. Paladins can also have a range of spells to heal themselves or smite their enemies, weaken foes, and Secrets to protect vulnerable targets.

Priest

• Devout healers with powerful restorative abilities, Priests use the power of Light to sustain themselves and their allies while pacifying enemies, but they can also use their darker abilities to manipulate and destroy enemies, peering into or even seizing control of their opponents' minds.

Rogue

• Subtle and evasive assassins, using flurries of swift sharp strikes to slice and incapacitate enemies, rogues prefer to wield light daggers, laced with deadly poisons. Rogues prefer to assault their opponents in rapid bursts of activity, activating Combos to gain powerful additional effects.

Shaman

• Masters of the elements, shamans command the service of mighty elementals, and even the Elemental Lords themselves. Shamans can Overload their mana in order to rise to the needs of the moment, with their attacks producing varying potency. Shamans can also summon Totems to boost their powers.

Warlock

• Calling nightmarish Demons to their aid, warlocks are willing to sacrifice their own life, cards, and even their own minions to overwhelm their enemies. Regarding their own lifeblood as nothing more than a currency, warlocks readily trade away their Health to draw additional cards, but must often pay a terrible price for the services of the infernal beings with whom they consort.

Warrior

• These lords of war use heavy weaponry and deadly attacks to slam and devastate the battlefield. While their skill with armor and shields allows them to soak up the mightiest of blows, their gladiatorial bloodlust brings synergy with Enrage and on-damage effects, sending their minions charging at the enemy.

Death Knight

• Due to their falling to the temptation of ultimate power, Death Knights' abilities are far more powerful than that of the other class and often have large sacrificial costs to the user. The abilities of a Death Knight cannot be wielded by just anyone - only those who call on a mighty champion of darkness can use their power.

Demon Hunter

Heroes

Unique mechanics

Demon Hunters have an in-your-face playstyle, using a variety of Attack-granting cards and weapons to attack directly, which combine well with cards effects that activate when their hero attacks or have scaling effects. They can use their fallen allies to fuel their power, possessing cards that become more powerful with more of their own minions lost on their turn, with many cards that generate fodder to boot. Demon Hunters are the only other class besides Warlocks to utilize demons liberally, summoning huge Fel demons to overwhelm their foes. The unique keyword for Demon Hunters is Outcast, which requires the card to be on the left or right-most side of their hand for the effect to activate. Whether it's saved for crucial moments or played out immediately, Outcast effects are powerful in either case.

Hero Power

Demon Claws has a small effect, basically the Druid's Shapeshift without the Armor gain, but uniquely it's the only basic Hero Power that costs 1 Mana as opposed to 2. This allows the Demon Hunter to use their Hero Power more efficiently and gives them more opportunities to get an attack in throughout the game. On its own it's good for removing small minions or adding up chip damage to the enemy hero, but its low cost lets them more comfortably trigger card effects that activate when your hero attacks or to give themselves a small boost with their weapon to empower card effects that scale with hero Attack damage.

Alternate Hero Powers

Please add any available information to this section.

All Demon Hunters begin with Demon Claws, which can be upgraded to Demon's Bite by Justicar Trueheart or Baku the Mooneater's effect. Casting Metamorphosis will temporarily replace the current Hero Power with Demonic Blast.

Example Cards

Druid

Heroes

Unique mechanics

The druid finds great versatility through the unique Choose One ability, allowing them to choose one of two options when playing certain cards. Druids boast a large range of enchantments with which to enhance their minions, and are known for having some of the biggest class minions in the game, such as Ironbark Protector and Ancient of War. Druids can also use cards such as Innervate and Wild Growth to manipulate and accelerate their mana gain to great effect. Druids also share a bond with Beasts, with a high number of unique Beasts as well as abilities that benefit them.

Hero Power

Shapeshift offers a combination of offensive and defensive benefits. It grants the druid a small but reliable source of Armor, mitigating damage from future attacks; and grants them a temporary point of Attack. The latter allows the hero to directly attack enemies, essentially granting them a weak weapon until the end of the turn. This can be useful for removing enemy minions, trading Health (or Armor) for board control, or simply for chipping away at the enemy hero. A blend of proactive and passive benefits, Shapeshift is a reliable option, even if there is no desirable target to attack.

Alternate Hero Powers

All Druids begin with Shapeshift, which can be upgraded to Dire Shapeshift by Justicar Trueheart or Baku the Mooneater's effect. The hero card Malfurion the Pestilent will replace the current Hero Power with Plague Lord. Completing Untapped Potential awards the hero power Ossirian Tear.

Example cards

Hunter

Heroes

Unique mechanics

Hunters favor Beast type minions, with numerous unique Beasts available to them, and many cards such as Starving Buzzard, Houndmaster and Tundra Rhino offering synergies with them. Hunters have limited access to ranged weapons with which to deal direct damage, while the hunter Hero Power allows them to deal 2 points of unstoppable damage to the enemy hero. Hunters also employ traps in the form of secrets to counter enemy actions. Hunters also have a vast pool of synergy with Deathrattle effects. With a host of faithful beasts at their command, hunters are excellently suited to an aggressive playstyle, with strong single-target removal abilities to sweep aside any opposition.

Hero Power

Steady Shot is an extremely direct and straight-forward Hero Power - it deals a small but significant amount of damage to the enemy hero. Unlike many other Hero Powers, this does not offer special synergies or boast a range of possible uses, but what it lacks in strategic complexity it makes up for in sheer effectiveness. Without Health or Armor granting effects, Steady Shot can single-handedly destroy the opponent and win the game in just 15 turns. This allows the hunter to rely upon Steady Shot's damage to make steady progress toward victory, regardless of the state of the board.

Alternate Hero Powers

All Hunters begin with Steady Shot, which can be upgraded to Ballista Shot by Justicar Trueheart or Baku the Mooneater's effect. The hero cards Deathstalker Rexxar and Zul'jin will replace the current Hero Power with Build-A-Beast and Berserker Throw respectively. Casting Dinomancy will replace the current Hero Power with Dinomancy. Completing Unseal the Vault awards the hero power Pharaoh's Warmask.

Example cards

Mage

Heroes

Unique mechanics

Mages are the undisputed masters of damaging and removal abilities, with an array of spells to cripple enemy minions and damage the opponent, from single target spells such as Pyroblast and Polymorph to multiple target options such as Arcane Explosion and Flamestrike. Mages have access to spells such as Frost Nova and Blizzard which freeze targets, preventing them from attacking for one turn, as well as spells like Fireball and Frostbolt that can be used either to remove minions or to directly damage the enemy hero. The mage can also use secrets that trigger when a certain condition is met. With a range of options to tackle threats, Mages are masters of board control, clearing or disabling enemy minions while placing their own.

Hero Power

At first glance, Fireblast can seem underwhelming compared to other Hero Powers, but its true strength lies in its tactical value. By being able to deal damage to almost any target regardless of Taunts or board state, the mage gains the power to enact a range of strategic plans, such as finishing off powerful but weakened minions, allowing for desirable trades, or even activating friendly effects like Acolyte of Pain or Amani Berserker. It can be used to add extra reach to damaging spells or attacks, to efficiently remove early threats like Murloc Raider, or simply to slowly chip away at the opponent's Health.

Alternate Hero Powers

All Mages begin with Fireblast, which can be upgraded to Fireblast Rank 2 by Justicar Trueheart or Baku the Mooneater's effect. The hero cards Frost Lich Jaina and The Amazing Reno will replace the current Hero Power with Icy Touch and What Does This Do? respectively. Completing Raid the Sky Temple awards the hero power Ascendant Scroll.

Example cards

Paladin

Heroes

Unique mechanics

The Paladin is a well-rounded class which focuses on strong minions and limiting your opponent's ability to use their own. The mechanic Divine Shield is most strongly associated with Paladin cards. Paladins can use weapons to attack directly, and can use secrets that trigger when a certain condition is met. Their Hero Power can be used to summon an endless supply of 1/1 minions. With spells that can heal, buff and protect minions, Paladins can potentially have some of the strongest minions in the game.

Hero Power

Reinforce provides a reliable stream of 1/1 Silver Hand Recruits. This can be useful for generally swelling the Paladin's board presence and for generating card advantage by trading for the opponent's minions. Effects like Sword of Justice and Raid Leader can be very effective at improving these weak minions. The constant presence of Recruits on the board also provides the perfect target for powerful buffs like Blessing of Kings, punishing the opponent should they ignore these seemingly weak minions.

Alternate Hero Powers

All Paladins begin with Reinforce, which can be upgraded to The Silver Hand by Justicar Trueheart or Baku the Mooneater's effect. The hero card Uther of the Ebon Blade will replace the current Hero Power with The Four Horsemen. Playing Vilefin Inquisitor will replace the current Hero Power with The Tidal Hand. Completing Making Mummies awards the hero power Emperor Wraps.

Example cards

Priest

Heroes

Unique mechanics

Priests are masters of healing, and can heal themselves and their minions through their Hero Power and a range of healing spells, as well as boosting minions' health through abilities such as Power Infusion. Priests' healing and Health-buffing theme is reinforced by synergies with spells such as Inner Fire and minions such as Lightspawn. However, these masters of the light also have their shadow side, and Priests command a number of darker abilities like Shadow Word: Pain and Shadow Word: Ruin to destroy their foes. They can also use these powers to peer into their opponent's minds, using cards like Thoughtsteal and Psychic Conjurer to copy their opponent's cards, or even dominate the opponent's minions with Mind Control.

Hero Power

Lesser Heal is the Priest's key healing ability, allowing the priest to consistently restore the Health of their minions or themselves, opening up a range of strategic and synergistic options. At its simplest, it can allow priests to steadily regain Health, returning from the brink of death to full Health, something which no other class other than the Warrior can reliably achieve. This can make Priests very hard to kill, and allow them to counter the steady deterioration of their Health from enemy attacks. Conversely, the Priest can restore their minions' Health, ensuring that there is always a threatening presence on their side of the board.

Alternate Hero Powers

All Priests begin with Lesser Heal, which can be upgraded to Heal by Justicar Trueheart or Baku the Mooneater's effect. The hero cards Shadowreaper Anduin and Galakrond, the Unspeakable will replace the current Hero Power with Voidform and Galakrond's Wit respectively. Casting Shadowform will replace the current Hero Power with Mind Spike, and casting Shadowform again while Mind Spike is active will replace it with Mind Shatter. Completing Activate the Obelisk awards the hero power Obelisk's Eye.

Example cards

Rogue

Heroes

Unique mechanics

Rogues have access to a lot of cheap cards, including several zero-mana cards. This works well with the unique Rogue ability Combo, with Combo cards granting additional effects when another card has already been played that turn. Rogues also can equip weapons and strengthen them to deal direct damage with their hero, oftentimes willing to sacrifice Health to gain good momentum. In addition to combos, Rogues specialize in Deathrattle effects and have the uncanny ability to pull out cards from other classes using cards like Pilfer.

Hero Power

Dagger Mastery equips a 1/2 Wicked Knife, providing the Rogue with an ever-ready (if very weak) weapon. This can be useful for dispatching minions and maintaining control of the board, and can work with effects like Deadly Poison and Blade Flurry to even greater effect.

Alternate Hero Powers

All Rogues begin with Dagger Mastery, which can be upgraded to Poisoned Daggers by Justicar Trueheart or Baku the Mooneater's effect. The hero cards Valeera the Hollow and Galakrond, the Nightmare will replace the current Hero Power with Death's Shadow and Galakrond's Guile respectively. Completing Bazaar Burglary awards the hero power Ancient Blades.

Example cards

Shaman

Heroes

Unique mechanics

Shamans can use Totemic Call to call Totems to their aid, a type of minions almost exclusive to shamans. With some handy utility effects, Totems can be helpful for survival or for aggressive play. Most Totems start with 0 Attack but cards like Bloodlust can turn a board of weak Totems into a force to be reckoned with. The Shaman also has access to cards with Overload. Overload allows powerful spells and minions to be cast for a low mana cost, but reduces the number of available Mana Crystals available the next turn. This allows the Shaman to deal great burst damage or to clear the board of threats for a low mana cost. Windfury is also most common among Shaman cards. In addition to a number of weapons, Elementals find themselves most at home in a Shaman's arsenal.

Hero Power

Every time you use the shaman Hero Power, one of 4 different Totems will be summoned at random. You cannot summon a totem that is already on the board, so the only way to have more than one of a specific totem is to utilize cards with effects similar to Youthful Brewmaster or Ancient Brewmaster. The 4 totems are:

Totemic Call is useful for reliably supplying extra minions for the board, and in potentially providing critical utility, in the form of a Taunt, Spell Damage, or healing. While most Totems have 0 Attack and therefore cannot be used to attack, various spells and effects such as Flametongue Totem or Bloodlust can be used to grant them additional Attack (and Health), or allow them to be used in other ways.

Alternate Hero Powers

All Shamans begin with Totemic Call, which can be upgraded to Totemic Slam by Justicar Trueheart or Baku the Mooneater's effect. The hero cards Thrall, Deathseer, Hagatha the Witch, and Galakrond, the Tempest will replace the current Hero Power with Transmute Spirit, Bewitch, and Galakrond's Fury respectively. Charged Hammer's Deathrattle will replace the current Hero Power with Lightning Jolt. Completing Corrupt the Waters awards the hero power Heart of Vir'naal.

Example cards

Warlock

Heroes

Unique mechanics

Warlocks are notable for their ability to summon demons. These underpriced minions generally come with a battlecry that is negative for the Warlock (e.g. discard cards or dealing damage to the hero) balancing their unusually low cost. Specializing in sucking the soul from their enemies, Warlocks also have a number of dark direct damage spells at their disposal. One of the Warlock's most iconic abilities is their Hero Power Life Tap, which allows them to sacrifice their own health in order to draw an additional card from their deck. This means that Warlocks will rarely suffer an empty hand - so long as they are willing to pay the price.

Hero Power

Life Tap is a powerful tactical Hero Power, allowing the Warlock to draw a card in exchange for both 2 mana and 2 Health. This can be very effective for both early game and late game decks, allowing Handlocks to quickly build a large hand of cards, or an aggressive Zoolock to consistently flood the board with cheaper minions.

Alternate Hero Powers

All Warlocks begin with Life Tap, which can be upgraded to Soul Tap by Justicar Trueheart or Baku the Mooneater's effect. Summoning Lord Jaraxxus will replace the current Hero Power with INFERNO!. The hero cards Bloodreaver Gul'dan and Galakrond, the Wretched will replace the current Hero Power with Siphon Life and Galakrond's Malice respectively. Completing Supreme Archaeology awards the hero power Tome of Origination.

Example cards

Warrior

Heroes

Unique mechanics

The Warrior can equip a range of weapons to attack their foes directly. Armor can also be easily gained from their Hero Power to remain at sustainable Health. Warrior cards feature an emphasis on effects that trigger when a minion is damaged, cards that target damaged minions, and minions that can Charge or Rush onto the battlefield. Warriors are a class of opposites, with cards that focus on viscerally entering the fray to deal direct damage and cards that protect the Warrior from harm.

Hero Power

Armor Up! allows the warrior to build a substantial stack of defensive Armor, acting as an extra barrier to enemy attacks. In contrast to Health, Armor can be stacked indefinitely. Armor Up! is a reliable option, effectively healing the warrior for 2 Health, but allowing the hero's combined defensive value to far exceed the maximum Health limit of 30. Shield Slam can even allow Armor to be used offensively.

Alternate Hero Powers

All Warriors begin with Armor Up!, which can be upgraded to Tank Up! by Justicar Trueheart or Baku the Mooneater's effect. Completing Fire Plume's Heart and equipping Sulfuras will replace the current Hero Power with DIE, INSECT!. The hero cards Scourgelord Garrosh and Galakrond, the Unbreakable will replace the current Hero Power with Bladestorm and Galakrond's Might respectively, while the hero card Dr. Boom, Mad Genius will replace the current Hero Power with Big Red Button, which itself cycles through five unique Hero Powers at random (Blast Shield, Delivery Drone, KABOOM!, Micro-Squad and Zap Cannon). Completing Hack the System awards the hero power Anraphet's Core.

Example cards

Death Knight

Heroes

• None

Unique mechanics

The Death Knight is a special class unique to a small set of uncollectible cards. It has no associated heroes, Hero Powers, or collectible cards; instead, Death Knight cards are generated by The Lich King, Arfus, and Transfer Student on the Knights of the Frozen Throne battlefield.

Design

• One rule for the developers in class design is to make sure that each of the classes "feels very strongly like its World of Warcraft class." This encourages the maintenance of constraints such as which classes have access to weapons and Secrets.

• As of Goblins vs Gnomes, adding specific minion type "themes" to classes is one "fun" way in which the designers aim to "make each class feel distinct and have its own flavor".

• Along with Hero Powers, class-specific cards are the main way of creating distinct playing styles and experiences for the different classes. However, in some cases effects allow players to use cards belonging to another class, such as Unstable Portal, Piloted Shredder or Grand Crusader. When a class starts imitating a behaviour specific to another class, this is known as "class bleed". In many cases, a small amount of class bleed can be fun and interesting, but too much can cause the classes to lose their sense of uniqueness or even their identity. As a result the developers try to maintain "the right amount" of class bleed in the game. For example, when designing the Discover keyword, the developers intentionally restricted the effect to class and neutral cards, as the keyword's initial ability to draw cards of any class added too much class bleed to the game.

• While class power is something the designers constantly struggle to balance, ultimately they feel having all classes precisely balanced is less important than ensuring that each has a time to shine.

• Class identities, which describe the strengths, limitations and weaknesses of each class, have only been formally described in June 2019. The hope is to avoid endless debates about whether a given new class-specific card does or does not fit in its class identity.

In development

• The only World of Warcraft classes currently missing from Hearthstone are death knight, and monk, with Demon Hunter finally being added in April 2020.
• In August 2014 Yong Woo stated, "the fact of the matter is that we already have 9 classes, and we feel there already is a ton of diversity and we frankly think that it has enough complexity right now for most people to sink their teeth into. So currently, we have no plans to add additional classes." In December 2014 Ben Brode stated "There are pros and cons [to adding a new class] and we have to figure out when, if ever, the right time would be." Brode elaborated: "A good design exercise is to think: "How many classes is too many?" My sense is that it's closer to 9 than to 20." In July 2017, Blizzard announced the Knights of the Frozen Throne expansion, which would feature the brand new hero card type, allowing Hearthstone's nine classic heroes to transform into death knight versions of themselves. When asked if this implementation of death knights had killed the possibility of whole new classes ever coming to the game, Mike Donais replied that "We’ve always said that we like the nine classes we have. We work really hard to try to give some class identity to those nine classes, and it’s tough, because nine is a lot. Adding a tenth or eleventh class isn’t something we’re interested in. It’s too hard to make class identity exist when there are that many different classes. So yeah, we’re not excited about the idea of making new classes."

• More alternate heroes are planned for development in the future.

Trivia

• The class colours in Hearthstone are notable for not always matching the traditional colours for those classes from World of Warcraft. Specifically, the rogue in World of Warcraft uses yellow, while in Hearthstone it uses black; the paladin uses pink, while in Hearthstone it uses yellow; the warrior uses brown, while in Hearthstone it uses red; and the druid uses orange, while in Hearthstone it uses brown. There are also numerous differences in shade, such as the hunter, which uses a deep green as opposed to its traditional avocado-like shade. According to Lead Artist Ben Thompson, this is because the colours in World of Warcraft were chosen largely based on suitability for use in the game's chat interface; with Hearthstone the developers therefore decided to choose in some cases new colours that they felt better suited the classes.
• In August 2016 Ben Brode stated that of all the classes he felt the team had the hardest time designing warlock spells, stating "We need to carve out more design space for them."
• At one point during the game's initial development there were two heroes for each class, one representing the Alliance and one representing the Horde. For details on early choices for each class, see Design and development of Hearthstone.
