** ''TabletopGame/EpicLevelHandbook'': The Lavawight and Shape of Fire have the blazefire ability which does exactly that.

* ''VideoGame/UndertaleYellow'': [[spoiler:In the battle against Ceroba during the Genocide route, she has access to Red attacks that will decrease the player's Max HP.]]

* ''[[Videogame/Sorcery2013 Sorcery!]]'': The time-travel spell ZED is actually a type of death curse. As such each time you use it or someone uses it on you, you lose 1 point of your maximum Stamina. Luckily the game has a number of ways of permanently adding to your max Stamina, so it's possible to outpace the loss.

* ''Videogame/{{Fallout 4}}'':
** This is its ''entire'' penalty and it's general more severe than before, as every 10 Rads takes off 1% of health. There are ways to remove rads and reverse the HP reduction, so it's not permanent.

* "VideoGame/SonicFrontiers": Happens during the DLC campaign "Final Horizon" while fighting the final boss battle with [[spoiler:the Titan "Supreme" which has been infected/possessed by THE END]], which will launch energy balls at you that will reduce your maximum Ring count by a certain amount for each hit you take by one of its energy balls.

* Dark Glass Corruption from ''VideoGame/RiseOfLegends''.

** ''Videogame/{{Fallout 4}}'':
*** This is its ''entire'' penalty and it's general more severe than before, as every 10 Rads takes off 1% of health. There are ways to remove rads and reverse the HP reduction, so it's not permanent.
*** There is a quest in which you are infected with a disease that lowers your max HP by 10; the quest culminates in finding a cure, but choosing between using it to cure yourself or to save the life of a young boy. If you save the boy, the HP reduction becomes permanent.

* Radiation damage in most of the ''VideoGame/{{Fallout}}'' games reduces max hit points both directly and indirectly (by lowering the stats that HP is derived from). In ''Videogame/{{Fallout 4}}'', this is its ''entire'' penalty and it's general more severe than before, as every 10 Rads takes off 1% of health. There are ways to remove rads and reverse the HP reduction, so it's not permanent.

** Some enemies and environmental effects will reduce your maximum HP, and this lasts until you heal at a shrine. The effects can stack down to death if you take enough hits or spend too long in the affected areas. Beware of purple.

* ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': A corrupting affliction known as Gloom is spreading across Hyrule. Touching pools of Gloom or getting hit by monsters corrupted by Gloom not only does damage, it prevents you from being able to heal from that damage (visualized by the heart icons being broken). The effect goes away when Link is bathed in [[LightIsGood natural sunlight, the glow of the underground lightroots, or drinks an elixir made with a sundelion]]. At the beginning of the game, Link is hit by a direct blast of Gloom so powerful, it ''completely'' reduces his hearts from 30 to 3. Every time Link collects a heart container or stamina vessel, a little bit of Gloom can be seen leaving his body. [[spoiler:During the final battle, Ganondorf can use these intense Gloom attacks to shatter Link's hearts, preventing him from restoring those hearts even through means that would normally dispel the Gloom. However, when the final phase begins, these shattered hearts are restored.]]

** The Viral status effect cuts both current and max HP in half for its duration.

* In ''WebAnimation/{{RWBY}}'', Pietro Polendina used a piece of his aura to make a penny, leaving him with a permanent weakened aura. When [[IncurableCoughOfdeath he coughs]] from a condition brought on by this state, his aura flickers over his body and scorch-edged holes are visible across it.

* In ''WebAnimation/{{RWBY}}'', Pietro Polendina used a piece of his aura to make a penny, leaving him with a permanent weakened aura. When [[IncurableCoughOfdeath he coughs]] from a condition brought on by this state, his aura flickers and burn like holes are visible.

* In ''WebAnimation/{{RWBY}}'', pietro polendina used a piece of his aura to make a penny, leaving him with a permanent weakened aura.

* ''VideoGame/TheBindingOfIsaac'': trading your HP for items from Satan or a Black Market will have this effect. There's also a "Health Down" pill that has this effect when used. Fortunately, HP increasing items are relatively common in the game, and can counteract this.

* ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': A corrupting affliction known as Gloom is spreading across Hyrule. Touching pools of Gloom or getting hit by monsters corrupted by Gloom not only does damage, it prevents you from being able to heal from that damage (visualized by the heart icons being broken).

* ''VideoGame/EtrianOdysseyVBeyondTheMyth'': The Camo Dog is a green-colored, six-limb creature found only in the hidden areas of Tutelary Forest. Its main attack, the Roar of Triumph, halves the party's HP for three turns. This can be eliminated before then with debuff-cleansing skills, but it's still advised to either kill or disable the enemy before it performs that attack (which is hard enough as-is, both for being durable HP-wise and having a high resistance to head binds).

* ''VideoGame/OctopathTravelerII'': Ups the ante by having the effect be active from the start of Castti's final battle as it is a toxic rainfall.

* In ''VideoGame/PlanescapeTorment'', your Nameless One can trade some of his organs to the burning mage Ignus for knowledge of some unique spells. This results in a small permanent loss of hit points.
* In ''VideoGame/{{Sorcery}}'', the time-travel spell ZED is actually a type of death curse. As such each time you use it or someone uses it on you, you lose 1 point of your maximum Stamina. Luckily the game has a number of ways of permanently adding to your max Stamina, so it's possible to outpace the loss.

* In the Career Mode of ''VideoGame/TestDrive: Eve of Destruction''[[labelnote:*]] ''Driven to Destruction'' in PAL regions[[/labelnote]], your car will suffer irreparable damage as it receives and inflicts punishment, which reduces its maximum condition, lowers the money you receive from selling it or trading it in, and encourages you to get rid of beat-up rides in order to stay competitive. Additionally, repairing your car at an Eve, on top of it being more expensive than repairing it at home, also increases the amount of permanent damage sustained, so reserve it for emergencies.

* In ''VideoGame/TheEndTimesVermintide'' and ''VideoGame/VermintideII'', most levels have two hidden Grimoires. Finding one and carrying it to the end of the level grants bonus loot, but ''each one'' reduces the entire party's maximum HP by [[PercentBasedValues 30%]]. This can be mitigated by AntiDebuff items or abilities.
