* ''VideoGame/ANNOMutationem'': Getting affected by Poison from {{Acid Attack}}s or DeadlyGas will inflict continuous damage with the LifeMeter being depleted by several digits per second until the effect fully subsides after a brief period or it gets immediately cured by the usage of [[ArtisticLicenseMedicine Erythropoietin]].

!!Examples

* Kebek from ''Silent Line: VideoGame/ArmoredCore'' is a lesser known Arena opponent, but all of its parts are geared towards whittling down your AP bit-by-bit. Insidiously, Kebek uses handguns (which deals Armored Core's version of status ailment via heat mechanics) that overheats your AC and slowly depletes your AP. His fighting skill is such that the description notes that his opponents (that might include the player) often fails to realize anything is wrong until it is too late. Kebek's AC's name? Chisel.

* ''VideoGame/DinoCrisis'' and ''VideoGame/DinoCrisis2 '' use the bleeding-out variety of damage over time, this was remedied by the Hemostat item.
* There are two varieties of poison in the ''VideoGame/DragonQuest'' series: poisoned and envenomed. The difference between the two? Poisoned characters are only damaged when walking outside of battle. Envenomed characters take damage both in and out of battle.

* ''VideoGame/HarryPotter'': This is one of two status effects that appears in the Game Boy Color games and is inflicted by the Mucus Ad Nauseam spell. It deals a set amount of damage at the beginning of the affected character or enemy's turn and notably, there's no ContractualBossImmunity to it in either game. In ''[[VideoGame/HarryPotterAndThePhilosophersStone Philosopher's Stone]]'', it can even be stacked, though with an MP cost of 80 that tends to be AwesomeButImpractical. In ''[[VideoGame/HarryPotterAndTheChamberOfSecrets Chamber of Secrets]]'', only the spell's third level has a stacking poison effect.
* ''VideoGame/HarryPotterHogwartsMystery'': This effect comes under various names, like nausea, bleeding, etc., but they all function the same way, sapping the opponent's health, and different types can stack together.

* VideoGame/JoJosBizarreAdventureAllStarBattle:
** Fugo can use virus capsules to poison the opponent, but he can accidentally poison himself. The capsule themselves are limited, and can only be regained through certain expensive moves. If Fugo evolves his Stand, the poison will inflict more damage on the opponent and way less damage to Fugo.
** Pucci's evolved stand [=C-Moon=] can inflict the Inverted Gravity status effect, which causes the afflicted body part to turn inside-out. In-gameplay, it temporarily inflicts damage over time, with the catch hitting an Inverted opponent with another gravity-inverting attack will instead cure them.
** A couple of Yuya Fungami's attacks allow him to attach his Stand to the opponent. This allows Yuya to gradually drain the opponent's [[LifeDrain health]] and [[ManaDrain super meter]] until he either uses a non-normal attack (which require his Stand, forcing him to recall it), activates his Stand On stance, or takes damage.

* ''Franchise/{{Mario}}'':
** The ''VideoGame/MarioAndLuigi'' games all have poison among their status effects, which comes in weak and strong varieties and deals damage over time. In ''Bowser's Inside Story'', Bowser can catch a cold, which has the same effects.
** In ''VideoGame/PaperMarioColorSplash'', one of the paint colors Roy can spray at Mario is purple. This poisons him and he takes damage for each attack he uses that turn.

* ''Videogame/MightAndMagic VI'' has deep water/lava acting as these unless countered by spell (this applies to entire Ernothian trilogy). However, there is also a confusing example in radiation damage - in late dungeon you encounter a room which is drenched in radiation, and setting a foot in this room inflicts on you a hidden status ailment that periodically damages your party and can't be cured by usual spells. It can be absorbed by specific item, but only at a certain chance, whith having more of this items boosting this chance. Thankfully, there are pools of water nearby which remove this status should you enter them.
* ''Videogame/MightAndMagic X'' has the Poisoned status that gradually decreases HP with each step taken until the person becomes Unconscious. The poison remains in effect even when you restore the HP or use TraumaInn, and must be cured manually. In previous games, the effect was different, affecting stats and HP/MP recovery instead.
* ''VideoGame/{{Minecraft}}'' has a poison status of three flavors. The first one is the standard Poison that reduces your health every second until a difficulty-dependent health value is reached or the timer runs out, but that leaves the player highly vulnerable to damage. It also turns the health bar greenish-yellow. The second variety of poison is Hunger or Food Poisoning, which may occur when you eat certain foods. The Hunger status rapidly increases exhaustion, draining a hunger point every 8 seconds, indicated by a green outline around the hunger bar and rotten shanks. The third variety is called [[MakeThemRot Wither]], caused by Wither Skeleton contact or Wither projectiles. It reduces health at the same rate as Poison. However, Wither is lethal; it ''will'' kill you if it doesn't wear out or get healed. It also turns your hearts black, making it difficult to keep track of your current health.
* ''VideoGame/MonsterHunter''

* In ''VideoGame/PathOfExile'' damage over time comes from StatusEffects like poison, bleed, and burning, as well as virulent magic and swirling vortices of ice. Because damage over time occurs as continuous HP loss rather than by ticks it is not considered to hit, which has both disadvantages [[labelnote: note]]cannot CriticalHit, cannot leech, cannot apply effects[[/labelnote]] and advantages [[labelnote: note]]cannot be reflected, blocked, or dodged, can be exploited with [[AdaptiveAbility Elemental Equilibrium]][[/labelnote]].

** In ''VideoGame/SouthParkTheFracturedButWhole, there is no effective difference between the three above status effects. However, it also introduced Shocked, which damages both the target and nearby allies after each turn.

* ''VideoGame/StarWarsTheOldRepublic'' gives every class (and some Mooks) options for this. Troopers and Bounty Hunters set enemies on fire or shank them to cause bleeds, Agents use poison darts and grenades, some Smuggler and Sith Warrior attacks leave bleeding wounds, Jedi Knights overload their sabers to burn enemies, while Jedi Consulars and Sith Inquisitors use a wide variety of Force curses that attack the mind, body, connection to the force, or others...

* ''VideoGame/WarcraftIII'' has two types of poison: Envenomed Weapons, which deal damage, and Slow Poison, which deals damage ''and'' slows the target.

* This is one of two status effects that appears in the ''VideoGame/HarryPotter'' Game Boy Color games and is inflicted by the Mucus Ad Nauseam spell. It deals a set amount of damage at the beginning of the affected character or enemy's turn and notably, there's no ContractualBossImmunity to it in either game. In ''[[VideoGame/HarryPotterAndThePhilosophersStone Philosopher's Stone]]'', it can even be stacked, though with an MP cost of 80 that tends to be AwesomeButImpractical. In ''[[VideoGame/HarryPotterAndTheChamberOfSecrets Chamber of Secrets]]'', only the spell's third level has a stacking poison effect.
* In ''VideoGame/HarryPotterHogwartsMystery'' this effect comes under various names, like nausea, bleeding, etc., but they all function the same way, sapping the opponent's health, and different types can stack together.

* In the ''VideoGame/IzunaLegendOfTheUnemployedNinja'' series, poisoned enemies take damage each turn. This only applies to enemies: for the player, poison instead has an AntiRegeneration effect.
* In ''VideoGame/IMissTheSunrise'', during certain boss missions, you can place your secondary fleets on certain tiles to gain "fire support" from them, causing a small but reliable amount of damage to the boss per turn.

-->'''Ancestor:''' Monstrous size has no intrinsic merit, unless inordinate exsanguination be considered a virtue.

*** Gore Magala and the adult form Shagaru Magala can both inflict the "Frenzy" status, which can apply both to monsters and hunters in different ways. If there's an outbreak of Frenzy (mentioned in the quest info), monsters will be Frenzied when you fight them, either at the start or in the middle of the fight. These monsters' [[RedEyesTakeWarning eyes glow red]], and their body becomes darker, and they hit harder but their speed becomes erratic -- from [[MightyGlacier slower than normal]] to [[LightningBruiser ridiculously fast]]. If you get hit by a Frenzy-infused attack, a meter will appear next to your status bar. If you deal enough damage before it fills, you'll overcome the Frenzy and gain an attack and [[CriticalHit affinity]] boost, but if it fills before you do so, you'll get infected, negating red health regeneration and making Frenzy-infused attacks hurt more.

* In ''VideoGame/GrimDawn'', almost all form of attacks have a damage over time variant: physical (internal trauma), fire (burn), cold (frostburn), lightning (electrocute), acid (poison), vitality (vitality decay) and bleeding.

* ''VideoGame/GrimDawn'' has the Occultist class, a type of witch. They can conjure and throw demonic eyeballs at enemies, which burst and cause poisoning. They also have a skill that inflicts Plague, which starts out as a self-replicating debuff status effect, but evolves into turning the enemy into {{Technically Living Zombie}}s who take constant damage over time. Finally, they have a skill that allows them to temporarily cause poison as a [[AttackBackfire Retaliation ability]]. Non-occultists can enchant their weapons (or find enchanted weapons) or take [[StarPower Devotion stars]] that turn them into a PoisonousPerson. And generally, aside from Bleeding standing on its own, every damage type has a version that works over time with a different name: Internal Trauma for physical, Burning for fire, Frostburn for cold, Electrocution for electric, Poison for acid damage and Vitality Decay for vitality damage.
* ''VideoGame/HorizonZeroDawn'' has Burning, which is caused by hitting a target with fire weapons. ''VideoGame/HorizonForbiddenWest'' adds Acid, which not only deals damage but also weakens the target's armor and [[ThisIsADrill Drill Spikes]], an ammo type used by some Spikethrowers. Once they hit a target, the Drill Spike starts burrowing into them, causing continuous damage. Unlike the other types, it's not a status effect so it can be used on an enemy that's already had a different status effect inflicted on them. And the effects are cumulative for each spike that hits them, so it can stack up to a lot of damage in a hurry.
* ''Juicy Realm'' from [=SpaceCan=] Games and X.D. Network has poison and a few weapons that can inflict burning, they also have the unique Honeycomb weapon which shoots a swarm of bees at the enemy and they cling on to the enemy to inflict constant damage.

* ''VideoGame/JurassicWorldAlive'': One of the status ailments a dinosaur can dish out is the aptly named [[ExactlyWhatItSaysOnTheTin Damage Over Time]], which by all visual means is actually a heavy bledding effect that cuts a select percentage of HP, bypassing the opponent's armor, dodge and shields.

* ''VideoGame/GalaxyAngel'': Mint's Emblem Frame, the Trick Master, trades mobility and burst damage (compared to the similarly-balanced Lucky Star) for a slower, yet steadier damage-over-time thanks to her multi-directional [[AttackDrone Fliers]] that has a constant damage output. Trick Master's [[LimitBreak Hyper Weapon]], Flier Dance, gradually wears down HP of enemy units in a designated area over time, and when sufficiently leveled, [[OneWomanArmy she can clear out an entire area of weaker enemies by herself]].

* ''VideoGame/PrayerOfTheFaithless'': Bleed hurts an enemy for 10 HitPoints at the start of their turn for as long as it lasts.

* ''VideoGame/JurassicWorldAlive'': One of the status ailments a dinosaur can dish out is the aptly named [[ExactlyWhaItSaysOnTheTin Damage Over Time]], which by all visual means is actually a heavy bledding effect that cuts a select percentage of HP, bypassing the opponent's armor, dodge and shields.

** Module T1-4 ''The Temple of Elemental Evil''. A {{PC}} in one of the four Nodes of Elemental Evil took 1-4 HitPoints of environmental damage per turn.

*** {{PC}}s on the Paraelemental Plane of Ice took 1-6 HitPoints of cold damage per round.

Damage Over Time is a common VideoGame mechanic where, instead of sustaining one-time sums of damage from one attack at a time, a unit receives a negative status that inflicts a small amount of damage at regular intervals, independent of any other factors or further attacks against them. The definition of an 'interval' varies by game: In action-based genres these intervals may be measured in real time, while turn-based genres (including non-video games, like a TabletopRPG) may measure intervals based on "turns" or "rounds".

Depending on how long the effect lasts, the accumulated damage can become significant, especially if combined with an AreaOfEffect to harm multiple targets simultaneously. On a mechanical level, this is the opposite of GradualRegeneration (and the "Regenerate" StatusBuff), and some varieties may officially neutralize or counteract each other.

** In ''Monster Hunter 4 Ultimate'', the flagship monster Seregios can inflict Bleeding, but instead of your standard damage over time, it'll hurt you if you do anything other than move normally. There are two ways of curing it: either crouching for a while or eating a meat product (Steak or Mosswine Jerky -- preferably the latter, as it's faster and recovers your red HP.) In ''Generations'', the Shogun Ceanataur can also inflict Bleeding.
** And as for the Plague, there's a "Frenzy" status, which can apply both to monsters and hunters in different ways. If there's an outbreak of Frenzy (mentioned in the quest info), monsters will be Frenzied when you fight them, either at the start or in the middle of the fight. These monsters' [[RedEyesTakeWarning eyes glow red]], and their body becomes darker, and they hit harder but their speed becomes erratic -- from [[MightyGlacier slower than normal]] to [[LightningBruiser ridiculously fast]]. If you get hit by a Frenzy-infused attack, a meter will appear next to your status bar. If you deal enough damage before it fills, you'll overcome the Frenzy and gain an attack and [[CriticalHit affinity]] boost, but if it fills before you do so, you'll get infected, negating red health regeneration and making Frenzy-infused attacks hurt more.

* ''VideoGame/LeagueOfLegends'' features a few poisonous abilities that deal tick damage. The Champions who make the most use out of it are Twitch, Teemo, Cassiopeia, and Singed.

* The Dancer in ''VideoGame/FinalFantasyTactics'' can inflict random status effects over the whole board. Over one turn it's not much, but it adds up. This works best with the Ninja Reaction Skill "Sunken State"- it turns you invisible when you get attacked. Invisible units can't be targeted, but the status goes away if you so much as enter the "act" menu. Which you never have to do after a Dancer (or a Bard, which is the symmetrical opposite of the Dancer) start her schtick.
