Main article: Warlock

In the face of demonic power, most heroes see death. Warlocks see only opportunity. Dominance is their aim, and they have found a path to it in the dark arts. These voracious spellcasters summon demonic minions to fight beside them. At first, they command only the service of imps, but as a warlock’s knowledge grows, seductive succubi, loyal voidwalkers, and horrific felhunters join the dark sorcerer’s ranks to wreak havoc on anyone who stands in their master’s way. Warlocks can ignite distant enemies in searing flame, send them fleeing in terror and pain, or afflict them with corrupting diseases and curses that steal the victim’s vitality.

These practitioners of the profane are feared across Azeroth, and many who have felt their wrath now prefer to fight alongside a warlock than against one.[2]

Hero Power[]

Life Tap
Main article: LegacyLife Tap
Who needs health and mana when you could have power?![1]

The warlock Hero Power is LegacyLife Tap, allowing them to sacrifice 2 Health (and 2 mana) in order to draw a card. While this may seem like an unworthy trade, the ability to gain card advantage is very strong, and Life Tap is widely considered one of the strongest Hero Powers in the game. It 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.

At the risk of losing powerful spells and allies, Warlocks can embrace the chaotic nature of fel magic, discarding a random card from their hand to activate powerful effects or summon unnaturally powerful minions.[1]

Strategy and gameplay[]

Many newer players may find themselves initially turned off from the warlock as the class makes heavy use of "self-abuse" mechanics in order to gain card advantage and summon more minions. Warlock cards generally offer a lower mana cost and higher power than their neutral and other class counterparts, but will come at an alternative price.

This style of play is most evident in their Hero Power LegacyLife Tap, which deals 2 damage to the player's own hero in addition to the standard 2 mana cost. However, the ability to draw cards on demand is well worth the higher cost, ensuring the warlock always has something to play. Health is sometimes just as valuable a resource for Warlocks, with powerful cards like The Grand TournamentWrathguard and Journey to Un'GoroBloodbloom demanding life as extra payment. Some cards even feed on the warlock's self-inflicted pain, such as Goblins vs GnomesFloating Watcher and Descent of DragonsZzeraku the Warped.

The warlock features a variety of Demon-class minions, many of whom offer greater power but will drain the warlock's resources in exchange. The LegacyFlame Imp and LegacyPit Lord require a portion of the warlock's health on play, but are vastly stronger than other minions of their mana cost. The LegacyFelguard is a cheaper defensive minion but lowers mana, while the LegacyVoid Terror can be a huge threat but requires the sacrifice of up to 2 of the warlock's other minions. Some cards allow warlocks to use these demons without incurring their drawbacks, such as Kobolds & CatacombsPossessed Lackey and Kobolds & CatacombsSkull of the Man'ari.

This reckless nature extends to warlock spells as well. LegacyShadowflame is an effective board clear at the cost of one of your own minions, while LegacyPower Overwhelming can turn a minion into a kamikaze powerhouse. On an even more destructive level, LegacyHellfire, Knights of the Frozen ThroneDefile, Mean Streets of GadgetzanFelfire Potion, and LegacyTwisting Nether can wipe out both sides of the board.

Other warlock-specific cards require the hero to discard their other cards to be put into play. LegacySoulfire, LegacyFelstalker and LegacyDoomguard all feature a very low mana cost for their power. A notable strategy to get around this downside is to continually play cards until only these remain, effectively negating the discard effect. Playing around discard effects is a key mechanic of the warlock class.

Due to the warlock's "self-abuse" mechanics, healing is premium for Warlocks. They have access to some healing cards like Kobolds & CatacombsDark Pact, Knights of the Frozen ThroneDrain Soul, LegacySiphon Soul, and Kobolds & CatacombsLesser Amethyst Spellstone. A strategy involving LegacyLord Jaraxxus can be also used to heal your hero back to 15 hp when your health has dropped too low. Although it is a powerful card that may turn the tide of a game, it is best not to play Lord Jaraxxus too early in case your opponent has been hiding large amounts of burst damage in his hand.

The warlock's LegacyLife Tap is useful for gaining card count advantages without wasting spots in your deck with draw cards. This ability is what makes warlock successful as an aggro class, and quite possibly the only class with a competitive zoo deck. These early game rush decks often utilize low cost cards with penalties like LegacyFlame Imp as well as efficient, high-quality neutral sticky minions to counter their best counter, AoEs. Especially in conjunction with heavy LegacyLife Tap usage, aggressive warlocks are relatively easy for opponent's to finish after they've run out of resources.

Warlocks are also considered a suitable class for late game, as their Life Tap allows them to consistently draw the cards they need to survive, until expensive and powerful cards can be put into play. Additionally, the large amount of cards they can gather up early game lets them play a LegacyMountain Giant or a high-health LegacyTwilight Drake as early as turn 4. While control warlock decks tend to lack offensive burst damage, they employ extremely sturdy minions like Voidlords and their array of board clears to gradually stem the opponent's tide and gradually outvalue them, whether it's summoning a huge LegacyInfernal every turn with Lord Jaraxxus or unsealing Kobolds & CatacombsAzari, the Devourer to destroy their deck and put them into fatigue.

Common deck types[]

The warlock can use a wide variety of deck archetypes to great effect.

A highly popular deck is the Zoolock, named because of its focus on low mana-cost, high 'value' minions. Zoolocks aim to seize board control in the early and mid-game with effective minion trading, creating an insurmountable advantage before the opponent's larger minions can even be played. LegacyLife Tap is critical in ensuring the warlock has a continual supply of minions and can refill the board in case of removal. Infamous for its power and efficiency, the Zoolock is a common choice at all skill levels. Its low crafting cost also makes the deck perhaps the easiest competitive choice for many new players.

The introduction of One Night in KarazhanMalchezaar's Imp with One Night in Karazhan has given rise to the Discardlock, a discard effect synergy-oriented version of the traditional Zoolock, negating the drawbacks of cards like LegacySoulfire and LegacyDoomguard and even turning them to positives through cards like One Night in KarazhanSilverware Golem and Ashes of OutlandHand of Gul'dan.

Another strategy is the Handlock, intentionally loading up their hand early for devastating returns. Once again LegacyLife Tap plays a key role in this deck, where the extra cards enable cards that scale with hand size like LegacyTwilight Drake, Descent of DragonsDark Skies, Descent of DragonsAbyssal Summoner, and LegacyMountain Giant. From there, their slew of board-clearing spells can wrench control back to the Handlock's grasp, before finally finishing them off with a LegacyLeeroy Jenkins or Descent of DragonsNether Breath after the opponent runs out of threats and their health whittled down.

Demonlock employs powerful but expensive Demon synergy cards and capitalize on them. Knights of the Frozen ThroneBloodreaver Gul'dan is the key to their power, and to maximize the impact of its Battlecry, they only a select few high-cost demons into their decks, namely Doomguards and Voidlords. On top of this, they can bring them out with lower cost and zero drawbacks with Kobolds & CatacombsPossessed Lackey and Kobolds & CatacombsSkull of the Man'ari and their power can be doubled up with a Kobolds & CatacombsCarnivorous Cube followed by Kobolds & CatacombsDark Pact.

When United in Stormwind was released, Warlock decks based around United in StormwindThe Demon Seed started to rise, due to the absurd speed you can complete the Questline in, as well as the reward, United in StormwindBlightborn Tamsin, turning your self harm AND Fatigue damage into burst. These decks usually employ cards like LegacyFlame Imp and Madness at the Darkmoon FaireBackfire to progress the questline and deal tons of damage. Healing like United in StormwindTouch of the Nathrezim and Knights of the Frozen ThroneDrain Soul are super important in keeping them alive to finish the quest.

Warlock is also probably the best class for decks built around The League of ExplorersReno Jackson, since LegacyLife Tap makes it possible to reliably draw Reno early, which is crucial for crushing aggro decks.


  • A highly offensive deck can be very effective to the generally suicidal mechanics of the warlock; generally to counteract the self-harm caused by the warlock spells and hero ability the warlock will have LegacySiphon Soul, LegacyDrain Life, different neutral cards and Taunt minions. An offensive deck can hit the warlock after every LegacyLife Tap for devastating results.
  • Silence or other crowd control is going to be very useful against the powerful warlock minions.
  • If you have the ability to drop the warlock below 15 HP, be careful because they may be holding LegacyLord Jaraxxus in their hand and can easily reset any damage that sends them below 15 HP that doesn't kill them.


  • 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."[3]
