History Main / PercentDamageAttack

* In addition to various HPToOne attacks, ''VideoGame/ChronoTrigger'' features several bosses (mainly Dalton and his Golems) who use attacks that drop your health to half of its current state.

Compare HPToOne, a more extreme attack that removes all ''but'' the last HitPoint from its target. If the damage percentage is 100% then you have a OneHitKill. Contrast RandomizedDamageAttack and SituationalDamageAttack.

* Played with in ''VideoGame/TeamFortress2'', where the Spy's BackStab does damage equal to a certain percentage of the target's health--namely [[ThereIsNoKillLikeOverkill 200%]] of it. And it has a 100% chance to {{crit|icalHit}}, making the effective damage 600%. For most purposes this makes it indistinguishable from a OneHitKill, but in certain conditions (most notably using the Dead Ringer) the target may have enough damage reduction that can survive the hit.

* In ''VideoGame/{{Persona 4}}'', while most Light element attacks are instant kills, one attack called "God's Judgement" reduces the target's current HP by half. Being part of the Light element, it can still be nullified/reflected by an appropriate Persona.

* The Eclipse Dark Tome reduces the target's HP by half in ''[[VideoGame/FireEmblemElibe Fire Emblem: Blazing Sword]]'' and ''VideoGame/FireEmblemTheSacredStones''.

* Gnostic abilities in ''Videogame/TheLogomancer''. A 50% one is a reward for completing an early {{Sidequest}}, and one [[OneHitKill inflicting 100% damage]] can be learned by level up. (Certain enemies also have a variant that inflicts 99% damage.) Interestingly, [[ContractualBossImmunity bosses are not completely immune]], just heavily resistant, so they can still be useful against them.

* The Sorceress in ''[[VideoGame/{{Diablo}} Diablo II]]'' has the Static Field skill, which does damage equal to 25% of target's current HP including bosses. Resistances and immunities apply. On Nightmare and Hell difficulties, this skill cannot reduce the health of enemies below 33% and 50% respectively. Against other players, it does only 4.375% damage after applying [[PlayerVersusPlayer PvP]] damage reduction.

** Where Malthael is great at whittling targets down, [[Videogame/StarcraftII Tychus]] is the premier burst tank-buster. His trait, Minigun, can be activated to let him to deal 2.5% of the target's max HP per basic attack for three seconds. He attacks four times per second by default (With a particular quest talent, this is taken up to five times per second), meaning that that is a whopping 10% of the opponent's max health gone ''per second''. He also gets a variant of Giant Killer for one of his level 16 talents (which does stack with Minigun), and the Titan Grenade talent applies this to his Frag Grenade, which makes it inflict 5% of the target's maximum health as extra damage.

* In ''VideoGame/HeroesOfTheStorm'', heroes can choose to pick a talent that can deal this trope, most commonly being ''Giant Killer'' and its variants, which deal anywhere between 1.5% to 3% of the target's HitPoints as damage.
** [[VideoGame/DiabloIII Kharazim]] take this trope further. Kharazim can use one of of his two [[LimitBreak heroic abilities]], ''Seven-Sided Strike'', to deal 7% of the target's HitPoints as damage [[RuleOfSeven seven times]] to enemy heroes in an area.
** Meanwhile, [[VideoGame/DiabloIII Malthael]] is this trope taken to its LogicalExtreme. His trait, ''Reaper's Mark'', marks enemy non-structures he damages with basic attacks, causing them to take an additional ''2.5% of their max health'' in damage every second for 4 seconds. And one of his [[LimitBreak heroic abilities]], ''Last Rites'', is similar to Necrophos' ''Reaper's Scythe'' from ''VideoGame/Dota2''. ''Last Rites'' deals extra damage based on missing HP, making it a FinishingMove if the target has less than 33% of their max HitPoints remaining.
** What, no mention of [[Videogame/StarcraftII Tychus]]? His trait, ''Minigun'', causes him to deal 2.5% of the target's max HP per basic attack. Oh, did I forget to mention that he attacks four times per second by default (With a particular quest talent, this is taken up to five times per second), meaning that that is a whopping 10% of the opponent's max health gone per second by default. He also gets a variant of ''Giant Killer'' for one of his level 20 talents (Which, yes, ''does stack with Minigun''), and the ''Titan Grenade'' Talent applies this to his Frag Grenade, which makes it inflict 10% of the target's maximum health as extra damage.

* ''VideoGame/LobotomyCorporation'' has pale damage, a Percent Damage Attack ''Type''. After damage calculations, 1 point of pale damage means losing 1% of your maximum health; therefore, receiving 100 points of pale damage is invariably fatal.

* The "Super Fang" move in ''Franchise/{{Pokemon}}'' reduces the opponent's HP by half, and is mandated to inflict ScratchDamage if the opponent is already reduced to one HitPoint (which may not be what you want in a ''Pokemon'' game). It is not affected by the game's ElementalRockPaperScissors beyond the fact that "Ghost"-type opponents are immune to its element.

** In ''VideoGame/SecretOfMana'' characters inflicted with "[[TakenForGranite Petrify]]" [[StandardStatusEffects status]] also lose 50% of their current HP as an immediate side effect.

* The ''VideoGame/DungeonsAndDragons'' spell Harm is a 100% damage attack, which reduces the target to one hit point above zero (or 1 to 4 hp above zero in some versions), meaning the next hit that does damage will kill it.

* The ''Franchise/KingdomHearts'' games use the Gravity spells from ''Franchise/FinalFantasy'' as well with their strength being determined by how high Sora's max MP to remove a percentage of remaining HP from bosses, with the added benefit of also flattening enemies and leaving them unable to attack. Although [[ContractualBossImmunity most bosses are immune]] and [[spoiler: all Heartless will get an increase in defense after beating Hollow Bastion the first time.]]

* The word "decimate" originates from a Roman military punishment, wherein soldiers found guilty of cowardice were ordered to draw lots, with one out of every ten[[note]] "decimus" is Latin for one-tenth[[/note]] men being executed as a result. The term is [[YouKeepUsingThatWord rarely used that way any more]].

An occasional variant is a FixedDamageAttack calculated using a percentage of the target's ''maximum'' HP, rather than their ''current'' HP. This is common for percent-based DamageOverTime.

** In ''VideoGame/FinalFantasyIX'' and ''VideoGame/FinalFantasyXII'', gravity-based damage is calculated based on an opponent's ''maximum'' HP rather than their ''current'' HP and therefore becomes a FixedDamageAttack.

* ''VideoGame/{{Worms}}" has the Battle Axe in some games, which halves the target's HP.

*** The FinalBoss has an attack with a spectacular animation that takes about two minutes to complete. It seems like an attack that should achieve an easy TotalPartyKill, but in fact all it does is take off 15/16 of each of your characters' current HP, so it's actually incapable of killing anyone.

* The Sorceress in ''[[VideoGame/{{Diablo}} Diablo II]]'' has the Static Field skill, which does damage equal to 25% of target's current HP including bosses. Resistances and immunities apply. On Nightmare and Hell difficulties, this skill cannot reduce the health of enemies below 33% and 50% respectively. Against other players, it does only 4.375% damage after applying PvP damage reduction.
