Execute · Game Mechanic Compendium

Definition

An execute is a damage ability that kills, or deals sharply increased damage to, a target whose remaining health is below a threshold or already reduced, so it finishes what other damage began. Backstab keys its bonus to position or awareness instead, and a coup de grâce on a helpless target belongs to backstab, since its trigger is a defensive lapse rather than health. Critical hits key a kill to a band of the attack roll, and spells capped by hit dice measure the target’s strength, not its wounds. Life drain returns damage to the user as healing; an execute’s payoff is the kill. A threshold that stops rather than kills is a stun; Mortal Kombat’s Fatality, after the match is won, changes no outcome.

Behaviour

Most forms strike one enemy, at spell range or in melee. The threshold is checked as the ability resolves: above it, the ability does nothing (Greyhawk, Star Wars: Unlimited), cannot be used (World of Warcraft), or deals ordinary damage (the 2024 rules). Greyhawk mentions no saving throw, and the 1978 and 2024 rules allow none. Counterplay is keeping health above the line.

Variations

Fallback damage (Dungeons & Dragons 2024 edition, League of Legends): a kill at or below the number, fixed or reduced damage above it.
Execute window (World of Warcraft): usable only below 20 percent health, with spare rage converted into damage.
Damaged flag (Magic: The Gathering, Hearthstone): any damage qualifies, so the card needs another damage source.
Missing-health scaling (League of Legends): Garen’s damage rises with missing health, without a hard threshold.
Kill refund (Dota 2, League of Legends): a kill resets the cooldown or allows a free recast.
Unpreventable strike (Dota 2 since patch 7.31): flat pure damage whose kill cannot be prevented, with no threshold; a borderline case.
Stagger finisher (Doom, 2016): damaged enemies enter a stunned state, and a melee glory kill finishes them and restores the player’s health.

Gating

The gate shared by every example is the target’s state, which no gating term names; a metered gate sits on top. Tabletop forms spend a 9th-level slot in 1975, 1978, and 2024, and the threshold rose with hit-point totals, from 50 to 60 to 100. World of Warcraft makes the ability cheap in rage but confines it to the last fifth of the target’s health. MOBAs put it on an ultimate with a 70 to 120 second cooldown, usually with mana and a kill refund. Card games charge one mana for Fatal Blow and Execute, which need earlier damage; Takedown costs 4, and its fixed threshold meets small units unaided. Every card form is discarded on play.

History and provenance

The earliest documented use cited is Power Word—Kill in Greyhawk (1975), which kills any creature of up to 50 hit points. Neither Greyhawk nor the 1978 Players Handbook says whether current or maximum hit points are meant, so confidence is medium; the 2024 rules read current health. Greyhawk’s Vorpal Blade and Sword of Sharpness, which sever on a high roll, are an antecedent through critical hits. World of Warcraft (2004) is the earliest video form cited; earlier video forms remain unsurveyed. Hearthstone’s Execute card is described as the World of Warcraft warrior attack, the documented line from that game; none is documented to the MOBA forms. Card games carried the damaged flag from Fatal Blow (1997) to Hearthstone’s Execute, and Star Wars: Unlimited prints the remaining-health threshold directly.

Notable examples

Notable examples, in chronological order. Notes describe how the ability behaves in each game; gating is what limits its use there; the latest reference is a widely played game from 2020 or later.
Game	Year	Medium	Gating	How the ability behaves
Dungeons & Dragons Supplement I: Greyhawk Gary Gygax and Robert Kuntz (TSR)	1975	Tabletop RPG	Spell slots	Power Word—Kill, a 9th-level magic-user spell, works like Power Word—Blind except that it kills instantaneously any creature of up to 50 hit points. No saving throw is mentioned. Its siblings Stun and Blind grade their effect by bands of hit points; Kill has a single cap and does nothing above it.
Magic: The Gathering Wizards of the Coast	1993	Board & card	Mana, Consumable	Fatal Blow (Weatherlight, 1997), a black instant costing one mana, reads "Destroy target creature that was dealt damage this turn. It can't be regenerated." Damage wears off at end of turn, so the card pairs with combat or a burn spell in the same turn. You Are Already Dead (2022) keeps the text and adds a card draw.
World of Warcraft Blizzard Entertainment	2004	Video	Mana	In WoW Classic (2019) values, the warrior's Execute is usable only on an enemy below 20 percent health, costs 15 rage, and converts up to 15 more rage into extra damage; the Improved Execute talent cuts the cost by up to 5. The values of the 2004 release are unconfirmed.
League of Legends Riot Games	2009	Video	Cooldown, Mana	Pyke's ultimate, Death From Below, strikes enemy champions in an X-shaped area, blinking to and executing those below a health threshold and dealing reduced damage to the rest; a champion dying in the area allows a free recast. Cooldown 100/85/70 seconds, cost 100. Garen's Demacian Justice instead adds a percentage of missing health as true damage, at no cost.
Dota 2 Valve	2013	Video	Cooldown, Mana	Axe's Culling Blade, a melee-range ultimate, killed enemies below a kill threshold until patch 7.31 (February 2022) made it pure damage. The current form deals 275/375/475 pure damage at 175 range for 100/125/150 mana on an 80/75/70-second cooldown, resets the cooldown and buffs allies on a hero kill, and its kill cannot be prevented by Shallow Grave.
Path of Exile Grinding Gear Games	2013	Video	Mana	Culling Strike kills an enemy whose life a hit leaves below a threshold, reportedly 10% for normal enemies. It has no cost of its own and rides on the mana cost of the skill that carries it; passive notables grant it against Marked enemies (3.12.0) and to Critical Strikes (3.27.0).
Hearthstone Blizzard Entertainment	2014	Video	Mana, Consumable	Execute, a 1-mana Warrior spell, reads "Destroy a damaged enemy minion." Any damage qualifies, so the threshold is being below maximum health, and another card usually supplies the first point of damage. Later Warrior cards such as Plague of Wrath destroy all damaged minions.
Dungeons & Dragons, 2024 edition Wizards of the Coast	2024	Tabletop RPG	Spell slots	Power Word Kill, a 9th-level enchantment cast as an action at 60 feet with a verbal component only, kills a target with 100 hit points or fewer and otherwise deals 12d12 psychic damage. No saving throw is allowed. It is on the bard, sorcerer, warlock, and wizard lists.
Star Wars: Unlimited Latest Fantasy Flight Games	2024	Board & card	Mana, Consumable	Takedown, a 4-cost Vigilance event from Spark of Rebellion, reads "Defeat a unit with 5 or less remaining HP." The cost is paid from the player's resources and the card is discarded on play; above the threshold it has no effect.

Provenance

Earliest documented use: Dungeons & Dragons Supplement I: Greyhawk (1975), tabletop rpg. Confidence: medium. Greyhawk's Power Word—Kill, listed among the all-new 9th-level magic-user spells, kills instantaneously any creature of up to 50 hit points. Confidence is medium because the text does not say whether current or maximum hit points are meant; read as maximum, the spell is a cap on the target's strength, like the hit-dice limits of Sleep, and falls outside the definition. The 1978 Players Handbook keeps the ambiguity at 60 hit points, and the 2024 rules settle it as current hit points. The reading as current health matches that of Power Word—Stun in the same book. Greyhawk's Sword of Sharpness and Vorpal Blade, which sever on a high attack roll, are critical hits and an antecedent only in their kill-outright outcome. World of Warcraft (2004) is the earliest video form cited, at low confidence: its 2004 tooltip is unconfirmed, and earlier video forms, such as EverQuest's Finishing Blow, remain unsurveyed.

Established form: World of Warcraft (2004), video. 29 years after the earliest documented use. Confidence: low. The warrior's Execute, usable only on an enemy below 20 percent health, is the best candidate the evidence supports: the Hearthstone Wiki's lore section describes Hearthstone's Execute card as the World of Warcraft warrior attack, "perfect for finishing off weakened opponents". The documented lineage is of the name; that the MOBA thresholds of League of Legends and Dota 2 follow World of Warcraft is undocumented, and the card's damaged flag matches Fatal Blow (1997).
