- For the abilities inMercenaries, seeAbility.

A selection of minions, each with its own ability. From left to right:Divine Shield,Deathrattle, atriggered effect, andSpell Damage.
Abilities are special effects, powers, or behaviors found oncards. Forspell andlocation cards, the ability describes the total effect of playing that card, while forminion andweapon cards, abilities are special effects or powers additional to the basic functions of the card. Abilities may be described in the card's text, or granted byenchantments.
Hearthstone features a large range of abilities. Abilities maytrigger in response to certain events, provideongoing effects to certain minions, or grant special powers or characteristics. Certain often-used abilities are written in memorable shorthand form using bold-faced keywords on the card, such as Battlecry or Deathrattle, while other abilities are written out with their full description in the card text.
Minion abilities granted by card text orenchantments can be removed using theSilence ability. However, abilities granted to minions throughaura effects generated by other cards can only be removed by neutralizing the aura-generating card.
Notes[]
- When multiple abilities are triggered simultaneously, the order of events is generally determined by the order in which the cards were played or summoned. For example, if two minions with Deathrattle die in the same combat, the minion which was summoned first will activate its Deathrattle first, followed by the minion which was summoned second. All triggered abilities will take place before the current phase of activity concludes.
- Although some abilities are only present on cards playable by a specificheroclass, these cards can be played by any hero that manages to acquire them in an ongoing game (e.g. throughThoughtsteal orMind Vision).
Keywords[]
- This section is about keyword abilities. For keywords used to search the collection, seeKeywords (collection manager).
Keywords are specific bold-faced words or terms printed on cards which specify a unique power or behavior without any explicit description.[1] Mousing over a minion card with a keyword ability will generate a text display describing the ability. For a more detailed exploration of each keyword, and a list of related cards, click on the respective section headings.
In almost all cases, when a new keyword and mechanic is added for an expansion set, that keyword isonly used in that set. There are a handful of exceptions, like expansion keywords that have been made evergreen since their introduction such asDiscover,Reborn, andTradeable; new keywords specifically designed to be evergreen, such asRush,Outcast, andOverheal; and existing effects being given keywords, such asLifesteal,Poisonous, andCasts When Drawn.
For a discussion of why keywords do not exist for some often-seen behaviors in cards, seethe trivia section.

Trivia[]
- According toBen Brode, the game'salpha featured 4 or 5 keywords which were removed from the game prior to the beginning of thebeta.[2]
Keyword creation[]
Keywords were specifically designed by the developers to help players to quickly recognise when a large number of minions have exactly the same ability, such as minions with Taunt, saving time spent reading each individual card's text. However, while keywords make it easier in cases where they are frequently encountered, when such examples are rare, keywords can actually serve to make understanding cards harder, requiring players to mouse over cards in understand to examine their abilities. The case of the "Destroy any minion damaged by this minion" effect was cited byBen Brode in 2014 as an example where the developers could have added a keyword, but chose instead to simply describe the ability in full, since it is was originally only found on 2 cards.[3] Senior ProducerYong Woo explained:
- "You know, keywords are double-edged swords. On the one hand, it really condenses information. I tell you Deathrattle and you know what it is right away. I tell somebody off the street Deathrattle and he is going to be like "What are you... selling me a snake?". They will not know what I am talking about, so it is a balance we have to reach between condensing the information and making too hard a set of vocabulary for new players to understand. It is something we continue to work on."[4]
Ben Brode has also stated that when a keyword conveys more than one behaviour rule, it can be hard for players to remember these from just the keyword.[5] For example,Taunt andCharge immediately convey that the minion possesses a single, specific ability.[5] In contrast, the "elusive" ability is tricky because it has more than one effect,[5] protecting the minion from both spells and hero powers, but not Battlecries or attacks.Ben Brode has stated that the elusive ability was "right on the razor's edge" regarding whether or not to create a keyword for it.[5]
Yong Woo has stated that it is possible in the future that keywords may be added for currently existing abilities such as the "elusive" ability of theFaerie Dragon,Laughing Sister andSpectral Knight - should there come to be a sufficient number of minions with that behaviour in the game.[4] Other card text for which keywords were considered, and for which keywords may be added in the future, includeon-draw effects andJoust.[6]
- New keywords
Following its launch, the game did not see the addition of any new keywords untilThe Grand Tournament, whenInspire was introduced. Inspire was initially represented by the text "Whenever you use your Hero Power do X", but the developers felt that replacing it with a new keyword would both save space on cards and also highlight the new mechanic as a key feature of the new expansion. They also felt that the game had been around long enough that it was acceptable to introduce a new keyword.[7] However, the developers did not choose to make the same expansion's newJousting mechanic into a keyword, partly because of a lack of synergy with established keywords, and partly because it is "more in depth" than other keywords.[8][9] Inspire also featured on a larger number of cards than Joust.[10]
The League of Explorers, the next major addition of cards, saw the debut ofDiscover. Originally intended to debut ina Tavern Brawl, the second added keyword was postponed due to technical difficulties.
A new keyword would not be added untilJourney to Un'Goro, withAdapt. A few months earlier, the long-standing "Poison" ability ("Destroy any minion damaged by this minion") was formalised, with the addition of thePoisonous keyword. The change was purely cosmetic, but appears to have been due to the introduction of a number of new Poisonous cards withUn'Goro, therefore justifying the creation of a keyword for the long-standing effect.
As the game grows, the developers feel increasingly open to adding new keywords.[11] When the game was new, Ben Brode says, the developers "really wanted to keep ourselves in check as far as the number of keywords we added and how quickly we added them",[11] but sinceThe Grand Tournament have begun adding keywords quite regularly. In 2018,Dean Ayala explained that the team tends to create keywords that are unique to specific expansions, to ensure that players don't have to learn "a hundred new mechanics" when they log intoHearthstone. As a result, new keywords tend to be introduced at around the same pace that old keywords rotate out of theStandard format. While all old keywords continue to exist in theWild format, Wild generally has more experienced players that are able to "learn new things a little bit more over time". However, Ayala emphasizes that player feedback plays a big part in deciding which keywords to continue using in future sets and which ones should remain expansion-specific.[12]
A handful of justified exceptions exist.Mega-Windfury was added withGoblins vs Gnomes for just one minion: the uncollectibleV-07-TR-0N, summoned byMimiron's Head'striggered effect. However, this keyword is followed on the card by the italicized text, "(Can attack four times a turn.)", essentially negating the use of the Mega-Windfury keyword. The redundancy can be explained by the obvious similarity between Windfury and Mega-Windfury, with the use of the keyword aiding players in immediately understanding the card's ability.Choose Twice was also added forone specific card, but is obviously based onChoose One. Likewise, theStart of Game keyword only appeared on three cards at the time it was added, but is justified by its self-explanatory name. The humorous keyword "Charrrrrge" was similarly added exclusively to the cardSkycap'n Kragg withThe Grand Tournament, but served only as a cosmetic variant on Charge.
