History Main / PercentDamageAttack

* In ''VideoGame/SecretOfMana'' characters inflicted with "[[TakenForGranite Petrify]]" [[StandardStatusEffects status]] also lose 50% of their current HP as an immediate side effect.
** The Moon Godbeast Dolan in ''VideoGame/SeikenDensetsu3'' possesses an attack that reduces a party member's current HP by half.

* ''OutpostDefenders'' has many items that deal a percent of the target's health. Usually, they are more expensive than other items, and they often only deal around 10% damage, making them only good for bosses.

* 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 Hallow Bastion the first time.]]

* {{Defense Of The Ancients}} has Huskar's ultimate, named Life Break, which does this to [[CastFromHitPoints himself]] as well as his opponent, with the damage he takes being reduced as it's leveled up.

** 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, 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.

* The 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.

* 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 [[CriticalHit crit]], 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.

* ''VideoGame/BravelyDefault'' has Bone Crush, which deals damage equal to the difference between the user's maximum and current HP. If the targets are at full or near-full HP, they ScratchDamage, while if they have half their remaining HP or less, it's a OneHitKill. You can get the spell yourself late in the game as BlueMagic (or the equivalent thereof). It also has Dark Breath, Dragon Breath, and Minus Strike, which are somewhere between this and FixedDamageAttack. Dragon Breath deals damage equal to the user's current HP, while the other two deal damage equal to the difference between the user's maximum and current HP. [[HealthDamageAsymmetry (Unfortunately for you, those two are also used by bosses....)]]

* In ''{{DROD}} RPG: Tendry's Tale'', stepping on a hot tile takes 5% of HP; stepping through an Aumtlich beam takes 50%. Optimisation often requires leaving healing potions untaken so your HP is low when you incur the percentage attacks, then taking them afterwards.

** In ''VideoGame/DigitalDevilSaga'', ''most'' Hama/exorcism spells reduce HP by a percentage with a decent chance of working (both of those depending on the spell), but they will instant kill enemies weak to them (Mudo/death is always a OneHitKill).

* Pretty much a staple of LeagueOfLegends in several variations as below. Designed as a major tactical decision for a player, since percent damage works extremely well against characters with lots of HP but few other defenses, but is very ineffective against people with low HP that rely on healing or armor to defend themselves. Certain types of percent damage attacks are more common for certain archetypes:

* The Eclipse Dark Tome reduces the target's HP by half in ''FireEmblem''.

** In ''DigitalDevilSaga'', ''most'' Hama/exorcism spells reduce HP by a percentage with a decent chance of working (both of those depending on the spell), but they will instant kill enemies weak to them (Mudo/death is always a OneHitKill).

* The ''Franchise/FinalFantasy'' series has many examples and frequently classifies them as a "gravity" element, featuring versions that remove 25%, 50%, and 75% of the opponent's HP, respectively. Some can target multiple foes simultaneously, and are far more likely to succeed when used against your party members than against monsters.

* [[InvertedTrope Inverted]] in ''TalesOfMajEyal'': the Chronomancy spell "Echoes from the Past" deals damage equal to a percentage of the damage the target has already taken rather than how much HP it has left.

* Played with in ''VideoGame/TeamFortress2'', where the Spy's BackStab does damage equal to a certain percentage of the target's health--namely [[ThereIsNoKillLikeOverkill 600%]] of it. For most purposes this is 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 ''FinalFantasyCrystalChronicles'', the "Gravity" spell can be used once per battle against a few bosses to inflict a percentage of damage. It also temporarily immobilizes airborne opponents after damaging them, making them easier to defeat.

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.
