Triggered effect

From Hearthstone Wiki

The lightning bolt icon, explicitly indicating a triggered effect

Triggered effects are effects that activate in response to specific events. Triggered effects may belong to minions, weapons or spells (in the form of Secrets), as well as some boss Hero Powers.

Triggered effects include named abilities such as Battlecry and Deathrattle, as well as unnamed effects such as those of Cult Master, Sword of Justice and Ragnaros the Firelord. All Secrets are triggered effects. Many triggered effects must first be put into play in order to become active - such as by playing the minion, equipping the weapon, or casting the Secret - while others activate when the card itself is drawn, discarded or put into play. Different types of triggered effect often share common rules for their activation.

Since the most common types of triggers are represented by keywords such as Battlecry, the term triggered effect is sometimes used more specifically to refer to those not indicated by a keyword, but instead described explicitly in their card text. Such effects are usually - but not always - denoted when in play by a small lightning bolt icon, a flask with venom (Poisonous), or a broken heart (Lifesteal) at the bottom of the card's portrait or icon, and can usually be activated any number of times, but only while in play. Any ability that states "at the end of your turn" or "at the start of your turn" is a triggered effect, as are most that state "when" or "whenever".

Notes[edit | edit source]

Main article: Advanced rulebook

The interactions and timing of multiple triggered effects are some of the most complex rules in the game. This section is only a summary:

  • When multiple triggered effects activate at once, such as at the end of a player's turn, the effects will activate in the order in which the minions were summoned, with the minions summoned first activating their triggered effects first. Any deaths resulting from the triggers then resolve at once, followed by consequences from those deaths. However, there are exceptions to this rule.
  • Triggered effects which trigger from playing cards or casting spells may take place before or after the card takes effect, depending on the trigger. For example, activating Leader of the Pack with a Violet Teacher active will cause her to summon a fresh Violet Apprentice, who will then benefit from the Leader of the Pack buff,[1] while playing Inner Rage on a 3/1 Wild Pyromancer will destroy the minion before it can activate its effect.
  • For notes on individual types of triggered effects, see the appropriate sections.

Advanced[edit | edit source]

  • Triggered effects require the card not to have been destroyed. However, the game only checks to destroy minions with 0 or negative Health when an event phase ends. This means that a minion can be triggered during the same phase in which it is destroyed, regardless of the order in which the events take place. For example, if three enemy Explosive Sheep are killed by your Flamestrike while you have an Acolyte of Pain on the board, the Acolyte will trigger three times (despite his Health reaching 0 after the first Exploding Sheep's Deathrattle) since he cannot completely die while the Sheep Deathrattles are still being handled. Once all simultaneous effects have resolved, the game will then check for any minions at 0 or lower Health, notice the Acolyte and destroy it. Conversely, Cult Master cannot trigger from the death of a friendly minion killed at the same time as the Cult Master itself, since by the time the game checks for triggers from the deaths, the Cult Master has also been destroyed.

Cards[edit | edit source]

Below are listed all cards which possess or grant triggered effects, divided by the type of trigger.

Using Hero Powers[edit | edit source]

Most effects which are triggered by using Hero Powers are denoted by the Inspire keyword. For more details on that effect, see Inspire. Certain other triggered effects are not marked as Inspire effects, but are activated by the use of Hero Powers.

Card-playing[edit | edit source]

Card-playing triggered effects only activate when a card of the correct type is played directly from the hand. Cards brought into play through summon or put into battlefield effects will not activate these effects.

Card-playing triggered effects activate immediately after the card is played, before it takes effect.

Playing a minion from the hand[edit | edit source]

These effects trigger only when the minion is played directly from the hand. For effects which trigger from any form of minion summoning, see Minion summoning, below.

That minion[edit | edit source]

Effects which activate when the minion itself is played from the hand are denoted by specific keywords. By far the most common is Battlecry, followed by the druid keyword Choose One and the rogue keyword Combo. All three abilities cause a special effect to activate when the minion is played from the hand, although some require certain conditions to be met.

The list of such minions is too extensive to list here - see individual pages for complete lists:

Secret-playing[edit | edit source]


Minion summoning[edit | edit source]

Minion summoning triggered effects may activate at various points during the summoning sequence of events. They may occur before auras are applied to the minion; after auras are applied to the minion, but before any Battlecries are activated; after Battlecries have taken place, but before the minion summoning has resolved; or once the minion summoning has resolved. In some cases they may sometimes activate later in the summoning process, if they did not activate at the proper point.

Note that these effects are triggered by any eligible minion being summoned, even if they are not played from the hand, such as through Summon or put into battlefield effects. Hero powers, Deathrattles, Battlecries and Secrets can all trigger these effects. If the summoned minion has a Battlecry, this will take place prior to the activation of any triggered effects or Secrets.[2]

Character damage[edit | edit source]

Damage-triggered effects activate immediately after damage is received, but before any deaths are resolved. On-damage triggers that cause healing can prevent a fatally damaged character from dying, as the game will not check for deaths until the end of the current phase is reached, and all simultaneous effects have been resolved.

Dealing damage[edit | edit source]

Various effects activate in response to dealing damage, either by the minion or by the player. Poison effects are a type of triggered destroy effect which display a vial of bubbling poison in place of the usual lightning bolt icon, and use atypical phrasing in their card text.

Minion death[edit | edit source]

Death-triggered effects activate only after the death has fully resolved, and the minion or weapon removed from play. All types of death-triggered effects, including Deathrattles, triggered effects and Secrets are queued together from oldest to newest played, with no special priority.

That minion[edit | edit source]

Effects which trigger from the death of the minion itself are Deathrattles - see that page for details.

End of turn[edit | edit source]

Most end of turn effects activate at the end of the controlling player's turn, but some activate at the end of the current turn, or at the end of each turn.

The game only queues end of turn triggers once, at the start of the end of turn phase. For example, if during the end of turn phase Kel'Thuzad resurrects a minion which has an end of turn triggered effect, that effect will not be activated that turn, since the minion was not in play when the end of turn phase started.

End of your turn[edit | edit source]

These effects activate at the end of the turns belonging to the controlling player.
