Commonly referred to as "Magic Points" or [=MP=] in {{Role Playing Game}}s and depicted by the ManaMeter.

A subset of LifeEnergy, mana is the [[PowerSource spiritual fuel]] that makes FunctionalMagic work--in addition to EyeOfNewt--and is used up as the character casts spells or performs other superhuman acts. Each character can use only a limited amount of mana before running out, thus restricting the number and strength of spells that can be cast consecutively. Typically the character has a store of mana on or inside his person (in which case this limit is caused by the character having a finite supply to work with), or draws it from a BackgroundMagicField on demand (in which case this limit is caused by the strain that gathering it places on their body).

How it's [[RegeneratingMana regenerated]] once used depends on the story. It could simply require rest or eating, or it could require more exotic means, such as IntimateHealing or feeding on the LifeEnergy of others. Sometimes all that's required is a good old [[{{Kiai}} primal scream]] and focusing on what's important, really, really hard with a lot of emotion.

Mana can have many names, and often overlaps with {{Ki}} in its depiction -- what differentiates them is how they are drawn out and used. Typically KiAttacks are martial-arts-based and can be improved through physical training, while wielding mana is [[MagicIsMental an exclusively mental affair]] which may [[RitualMagic require components and rituals]]. But prior to leaving the body, the "stuff" used seems to be the same.

If someone has a ''lot'' of mana stored up, expect various people in {{anime}} to [[ReadingsAreOffTheScale comment]] on how their [[AuraVision aura]] is strong.

The term is a Melanesian/Polynesian word for the power of the elemental forces of nature, as embodied in an object or person (essentially a badass is someone with lots of mana). The current usage no doubt descends directly from Creator/LarryNiven's novel ''Literature/TheMagicGoesAway'' and related stories from the 1970s, in which he used "mana" to refer to the non-renewable resource which powered magic in prehistoric times, whose depletion ushered in the "modern" historical era.

''Not'' to be confused with the holy sustenance (often assumed to be breadlike, though the original source describes it as being quite different) rained from heaven by God for the Israelites in Literature/TheBible. That's ''manna'', with two Ns.

A ManaPotion can be a way on hand to restore used up mana, or it can restore on its own with RegeneratingMana.

Compare with VancianMagic. See also PsychicPowers (the SciFi genre's version of human special powers).

ManaMeter is a subtrope.



[[folder:Anime & Manga]]
* In ''Manga/MermaidMelodyPichiPichiPitch'', Michel stole LifeEnergy apparently to fuel his powers and make him stronger. While this is part of it, it soon turns out that the other part is just to keep himself alive through the process of [[spoiler:altering his DNA to merge with Michal.]]
* ''Manga/DragonBall'': "Sentô-ryoku (literally "fighting power", and actually called such in the Latin American dub)" or "Power level" is an famous use of this trope; it resembles Ki. Note that power level isn't something that can be used up like most of the other examples and is more like a CharacterLevel than a ManaMeter. It can go down, but only if the character is ''really'' low on energy. Generally when it starts dropping, that means the fighter is on their last legs, and is fighting to stay conscious. (On one occasion, Gohan actually got his dropped to zero when Recoome ''broke his neck''.) Senzu beans are the local ManaPotion equivalent, which instantly heal all injuries and restore one's fighting power to full strength; normally it's replenished only by rest and recuperation followed by lengthy power-up sequences involving yelling and grunting.
* Manga/ShamanKing had "Furyoku", which is translated as "Mana" in the English manga.
* ''Manga/MahouSenseiNegima'' outright uses RPG terminology to differentiate Chi as [[HitPoints HP]] and Mana as MP. KiAttacks are the ability to draw on one's own internal LifeEnergy, and Magic is the ability to manipulate and draw in elemental forces from without. Using one interferes with the other ''unless'' one somehow knows the [[YinYangBomb "Kanka Technique"]] which fuses them. Negi's ability to share mana with his students via "Pactio" contracts is impressive.
* "Reiryoku/Spiritual Energy" in ''Manga/{{Bleach}}''. Not to be confused with "Reiatsu/Spiritual Pressure", which is what energy is being ''released''.
* "Chakra" in ''Manga/{{Naruto}}'' is the fuel for all ninjutsu, genjutsu and some taijutsu. Naruto's ace in the hole, especially early on, is that he has '''much''' more chakra than anyone else (even after accounting for [[UnskilledButStrong his highly inefficient usage]]). If he runs out, he can [[SealedInsideAPersonShapedCan badger his demonic passenger for more.]]
* "Reiki," "Yoki," [[spoiler:and "Seikoki"]] in Manga/YuYuHakusho are three forms of energy that can be used to perform magic and other supernatural feats.
* ''Franchise/LyricalNanoha'' has "Linker Cores," which are ethereal organs in the bodies of mages and magical creatures that store magic power. It can be temporarily drained but replenishes over time.
* ''Manga/FairyTail'' uses "Maryoku"/Magic Power, which functions as this. It may also be used by wizards to power external {{Magitek}} devices not related to their innate capabilities. PoweredByAForsakenChild is a common situation in the setting. Replenishing it takes time, unless you're a Dragon Slayer who can consume their respective element to regain combat ability quickly. And of course the limitations are utterly ignored when ThePowerOfFriendship comes into play.
* In ''Manga/ZatchBell'', this is simply called "[[ExactlyWhatItSaysOnTheTin Power from Within]]."
* In ''LightNovel/ACertainMagicalIndex'', there is natural mana produced by ley lines on the Earth, but there are also several ways to produce mana, which is why there are different schools of magic. However, mana is incompatible with AIM fields of espers, which disallow the existence of a magician-esper hybrid. AIM fields also function as the science-side equivalent of mana, produced by the Personal Realities of espers. Huge enough amounts of it can result in the creation of [[OurAngelsAreDifferent artificial angels]]. Telesma, meanwhile, is the variation used by [[OurAngelsAreDifferent real angels]]. Telesma is highly dangerous, destructive, and cannot be controlled by humans, unless there is a medium such as [[PublicDomainArtifact the Curtana]] in England.
* Mages (that is, pretty much everyone) in ''Anime/{{Maburaho}}'' have limited numbers of spells, and their numerical mana is extremely difficult to replenish without making a DealWithTheDevil. Running out of spells causes ''instant death''; though, fortunately, they seem to be able to measure their remaining spell counts very precisely and most people ([[ButtMonkey except the protagonist]]) are born with hundreds or even thousands of spells.
* In ''LightNovel/{{Slayers}}'', although the term "mana" is never actually used, all spellcasters tap into magical energy to fuel their spells. Indeed, the novels confirm there are two {{Fantastic Measurement System}}s relating to a mage's affinity for mana; pool capacity (how much of a mana reserve they have) and bucket capacity (how much they can tap from their reserve at once).

[[folder:Comic Books]]
* In ''ComicBook/GoldDigger,'' all living creatures produce "ether," which hovers invisibly around them. For most people, the stuff is both undetectable and useless, but spellcasters use it to power their spells. Rakshasas like Gen [[PhlebotinumMuncher eat the stuff]].

* The energy meter in the ''LARP/OtakonLARP'' can vary slightly. It may represent Magic, Chi, or Psionics. Essentially, they all represent a characterís ability to use powerful abilities in a limited form. They rarely overlap, and not every character has an ability that requires the use of their energy meter. A character whose Mana is reduced to Zero can continue, but cannot use or maintain any abilities that require whichever form of Mana the ability uses. [[RegeneratingMana Mana is restored at noon and midnight every day.]]

* In Creator/LarryNiven's ''Literature/TheMagicGoesAway'' series, Mana is a non-renewable resource, and generations of basing entire civilizations on heavy magic use eventually drains the entire world. Later stories (not all written by Niven) reveal that Mana comes from [[spoiler:the Sun, raining down on the world like light does, only someone had erected a tremendous shield around the world to prevent any more Mana falling upon it]].
* ''Literature/NightWatch''. ''Others'' do appear to use some internal generation of mana-like power, but [[spoiler: it's the opposite. Magicians are the ones that ''cannot'' generate this "mana", but can only use what normal people generate. The higher their [[PowerLevels level]], the ''less'' of this "mana" they generate.]]
* It's usually called Essence in the Literature/WhateleyUniverse, and what makes a mutant a 'wizard' type is the natural ability to call it up.
* In ''Literature/{{Warbreaker}}'', [[FunctionalMagic BioChroma]] is fueled by an energy called "Breath", which is an aspect of the human soul. People are born with one Breath, but can give it away fairly easily to someone else (which doesn't kill them, though it does dampen their ability to perceive the world), and many wealthy and powerful individuals stockpile ''thousands'' of Breaths. The more Breaths one has, the more spectacular magical effects one can produce.
* ''Literature/TheStormlightArchive'' by Creator/BrandonSanderson features the titular Stormlight. This mysterious energy is carried in the uber-hurricanes known as highstorms, and can be stored in gemstones (gems are charged by leaving them outside in a storm). Once charged, gemstones can be used to fuel the [[{{Magitek}} fabrials]]. Additionally, the mages known as Surgebinders can draw Stormlight from gems and hold it in their bodies for short periods of time, which boosts their physical abilities and allows them to expend Light to use their various powers. ''Literature/WordsOfRadiance'', the second book in the series, reveals the existence of a person with the unique ability to metabolize food directly in Stormlight.
* ''Literature/TheBannedAndTheBanished'': Mages of the Chiric and Choric styles store mana in their hands, which turn a dark red shade that lightens as the power is slowly used up. Both types can recharge from sunlight, and Choric "wit'ches" can also use moonlight or the glow from a ghost (gaining access to different types of spells when they do so.) However, they can't recharge a hand unless it's completely empty of power, which can be problematic if a Chiric mage is running out of mana near sundown.
* The ''Recap/MagicTheGathering'' novels have had several explanations for how Mana (symbolized in the game by Land cards, such as Mountains for red mana, or Swamps for black) worked. Niven's ''The Magic Goes Away'' was an inspiration in the game, but the official canon eventually created its own explanation: that mages could focus on strong memories of a place to draw power out of it. Jeff Grubb's novels, which worked out most of the details, focused heavily on mages' personal connections to the lands they drew upon, to justify how the game mechanics would work out in the world. Later books downplayed the memory aspect of it all.
* In the ''Literature/DragonsAndDwarves'' duology, the energy that spills through the gate and allows magic in Cleveland is called Mana.
* In the web-novel ''Literature/{{Domina}}'', characters with powers make constant references to their "reservoir," their power source. Everyone has a different one, and they drain and replenish at different rates. Laura, notably, doesn't appear to have one, though that might just be because her power is so easy to use that she's never noticed.
* In the ''Literature/ToughMagic'' series, magic is measured by sorvs.
* ''Literature/JourneyToChaos'': The source of power for all magic (but not all spiritual skills). It flows from the Sea of Chaos, through the veins of Noitearc, and into world fruit through the Eleven Mana Gates. Then it can be used by the people living in those world fruit as fuel for spells. Its absence on Threa (Eric's homeworld) is the reason why no one on Threa can perform magic.
** ''Literature/AMagesPower'' demonstrates its necessity for life before that of magic. Eric, who has been starved of mana for his entire life, discovers that even the most bland of Tariatlan food tastes delicious because it is loaded with mana.
** ''Looming Shadow'' shows this from the opposite direction-without mana Eric cannot cast magic nor enjoy food.
* In the ''{{Literature/Discworld}}'' series, research wizards have isolated the basic unit of magic, called the thaum, which is enough magical energy to create one white pigeon or three billiard balls. Further research has shown that thaums are made up of resons (literally ''thingies''), which can be divided up into five "flavors": up, down, sideways, sex appeal, and peppermint.
* In the ''Literature/SchooledInMagic'' series, magic is fueled by mana both from within the body and from the world around them depending on the type of magic being used. For example, a rune or spell-work might be powered by a ley line running below a site. Mana is not limitless and can be used up and dissipated. Or it could build up in a location (like at a ley line) and cause strange effects.
* ''Literature/{{Mithgar}}'' has <fire> (spelled with angle brackets to distinguish from other uses of the word "fire"), the innate life-energy of all beings. Every living thing and most inanimate objects have <fire>; [[WitchSpecies Mages]] have a natural ability to tap their own <fire> and use it to cast spells, at the cost of [[CastFromLifespan causing them to age]] (they can regain lost youth through extended hibernation). [[EvilSorcerer Black Mages]] instead use other peoples' <fire>, taken from them through a [[PoweredByAForsakenChild less than pleasant]] process; Mage society at large finds this practice abhorrent, and Black Mages are treated as outcasts and criminals.
* In ''Literature/ChildrenOfTheBlackSun'', the main limitation on mages' power is not how much magic they can handle but how much they can gather in. Their abilities in this regard are basically determined by birth. The lowest grade of mage never has more than a small amount of magic, and can't do anything about that fact. Higher mages, however, can use rituals which gather magic to themselves, allowing them to perform greater feats provided they've had a chance to charge themselves first. And then there are Sympaths like the protagonist, who sweep up vast amounts of magic from the senses and emotions of people around them automatically. It was the villain's plan to use the protagonist as a magic accumulator, surrounding her with pain that fed her magic and then taking that magic for himself. Her escape from him starts the plot.
* In ''Literature/TheTraitorSonCycle'', the hermeticists must gather energy from the outside and can't cast once they've run out of it, unless they recharge. The two most popular sources are the sun (golden magic) and the Wild (green magic), though it turns out death is a good mana source as well (BlackMagic).
* In ''Literature/TheBlackMagicianTrilogy'', mages' magic reserves are a pool of energy that renews with rest, while BlackMagic is the forbidden practice of fatally draining others' LifeEnergy for use as Mana. In a variant, it can also be infused into construction to serve as a permanent ReinforceField. [[spoiler:An invasion squad of black mages is thrilled to realize that every building in the nobles' district is a mana reserve...]]
* ''Literature/SufficientlyAdvancedMagic2017'': What is used to power magic items and activate attunements. There are many different types of mana, generated from seven different places on the human body: The left hand, the right hand, the left leg, the right leg, the mind, the heart, and the lungs. An attunement mark will appear on one of these points and indicates which part of the body is best at producing mana for improving that attunement. Corin is terrified of overusing his mind mana because it can cause brain damage, but everyone tells him he is being overly cautious. He invents a watch that can identify how much mana someone can use before it starts becoming dangerous, and discovers that everyone was right, he really was being too careful with his mental mana.

[[folder:Myths & Religion]]
* Aside from the non-example of ''manna'' mentioned in the introduction, there ''is'' a reference to something like this in Literature/TheBible. When an old woman touched UsefulNotes/{{Jesus}}'s robe, believing it would heal her disease, he noticed despite being in a large crowd of people because he felt "virtue" (Greek ''dunamis'') flow out of him.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** It doesn't use this for magic, instead having a VancianMagic system, but does use it for [[PsychicPowers Psionics]], which have a pool of Power Points. You can also [[TimTaylorTechnology spend more Power Points when using weak powers to put them on par with their higher-level counterparts]], though there is a limit on how much PP you can expend at once. Certain feats and class features allow characters to [[ExplosiveOverclocking "Overchannel"]], which increases this limit but also [[CastFromHitPoints causes the user to take damage from the strain]].
*** In 4th Edition, instead of having both At-will and Per-encounter powers like most classes, psions have lots of At-will powers which can be boosted to Per-encounter strength by expending Power Points from a limited pool.
** ''Unearthed Arcana'' has a "Spell Points" variant rule which makes wizards and sorcerers work more like psions, though since most spells weren't designed for this kind of scaling, it ends up being easier just to play a psion and call it a wizard.
* The ''TabletopGame/DarkSun'' setting has a Mana system, as spellcasting required drawing power from living things in one's environment. Preservers drew power slowly from their surroundings, so they didn't kill anything; while Defilers drew power quickly and forcefully, destroying plant life around them and leaching vitality out of the soil (and eventually even harming animals), as good as salting the earth. In case you couldn't guess, the world of ''Dark Sun'' is mostly a desert now. Most people have come to rely on psionics instead of magic as a result.
* In ''TabletopGame/{{Pathfinder}}'', although the fundamental spellcasters rely on VancianMagic like ''D&D'', several classes make use of what are essentially mana systems to fuel various class abilities. Almost always these are for augmenting their other powers rather than being their primary mechanic. Monks and Ninjas use a "ki pool", TheGunslinger uses a "grit pool", and the {{Ma|gicKnight}}gus uses an "arcane pool". The Summoner has a slightly modified version: Evolution Points are used to buy the various abilities and attributes of their [[BondCreature Eidolon]]. Arcanists are probably the closest as yet with their "arcane reservoir", as many of the abilities fuelled by the reservoir are similar to spells in effect (options include sending out bolts of lightning or icy projectiles at foes, for instance), the reservoir can be used to strengthen your (semi-Vancian) spells, and a master arcanist ''can'' use the reservoir to cast spells instead of expending a spell slot.
* ''TabletopGame/SpheresOfPower'' Spell points. [[DefiedTrope Unlike most other implementations of this mechanic]], you can still use your spheres' base talents when you're out of spell points, you just can't augment it or activate some of the deeper talents.
* In ''TabletopGame/MagicTheGathering'', mana is drawn from the land, though some creatures (both humanoid and not) can provide it as well. In addition, mana is divided into five colors, and each color can only fuel certain kinds of spells.
* In ''TabletopGame/DuelMasters'', any card can be placed into the mana zone. To summon a creature or cast a spell, the player must tap the required number of cards from the mana zone.
* "Energy" in the ''TabletopGame/{{Pokemon}}'' TCG must be attached to the characters for them to use certain powers. Some of the powers require a certain "colour" of mana (like the ''TabletopGame/MagicTheGathering'' example) while others require the energy cards to be discarded in order to activate.
* Almost every ''TabletopGame/TheWorldOfDarkness'' game has its own version of Mana, conveniently broken down into points:
** Both ''TabletopGame/VampireTheMasquerade'' and ''TabletopGame/VampireTheRequiem'' use Vitae (mystically-enhanced blood) to fuel Disciplines. Vitae is measured in blood points.
** ''TabletopGame/WerewolfTheApocalypse'' uses Gnosis (the ambient power of Gaia), while ''TabletopGame/WerewolfTheForsaken'' uses Essence (the stuff of the spirit world).
** ''TabletopGame/MageTheAscension'' uses Quintessence, the "free" version of the energy that, when bound up, makes all of creation. ''TabletopGame/MageTheAwakening'' uses Mana, the essence of the Supernal Realms filtered down into the Fallen World. Both systems are unusual in that mages don't need to spend Mana to cast spells -- they can optionally spend it to keep their magic from screwing up in the worst possible moment.
** ''TabletopGame/PrometheanTheCreated'' uses Pyros (a raw form of the "Divine Fire" that enacts change in the universe).
** ''TabletopGame/WraithTheOblivion'' uses Pathos, emotional strength reaped from humans.
** ''TabletopGame/ChangelingTheDreaming'' and ''TabletopGame/ChangelingTheLost'' both use Glamour, although they use it to refer to different things; for ''Dreaming'', it's the substance of dreams and creativity, while for ''Lost'' it's basically the same thing as Pathos, above.
** ''[[TabletopGame/GeistTheSinEaters Geist: the Sin-Eaters]]'' uses Plasm (the stuff of the dead), which can be gathered by visiting the Underworld, staying in haunted houses... or eating ghosts.
** ''TabletopGame/HunterTheReckoning'' uses Conviction (a measure of the inner reserves of the hunter's devotion).
** ''TabletopGame/DemonTheFallen'' uses Faith (human faith, reaped and processed by demons through divine revelation). ''TabletopGame/DemonTheDescent'' uses Aether (waste energy produced by the God-Machine).
** ''TabletopGame/KindredOfTheEast'' uses Chi (the energy that flows through the world).
** ''All'' races have Willpower (raw inner strength), which is used similarly and often in concert with the above. Mortals with special powers (such as hunters from ''TabletopGame/HunterTheVigil'') use it exclusively in place of other forms of "mana".
** In ''TabletopGame/MummyTheCurse'', while the Arisen gain power from Sekhem, they have no "common" pool of power. Rather, they draw strength from their five defining soul Pillars, and may need to spend from one or the other depending on circumstances. Meanwhile, in ''TabletopGame/MummyTheResurrection'', the Amenti have Sekhem as their "common" pool of power, representing the life energy flowing through the world.
** The major exception is ''TabletopGame/BeastThePrimordial'', which has Satiety, representing not so much any form of energy as it does how well the Horror inside has fed.
* ''TabletopGame/TrinityUniverse'':
** ''TabletopGame/{{Trinity}}'' uses Psi, the psionic energy that permeates the universe.
** ''TabletopGame/{{Aberrant}}'' uses [[SciFiNameBuzzwords Quantum]] as fuel, which apparently is generated automatically over time.
** ''TabletopGame/{{Adventure}}!'' uses Inspiration, representing "telluric energy" drawn from an energy field propagating through the universe.
* ''TabletopGame/{{Exalted}}'' uses rules similar to the classic ''World of Darkness'' Storyteller system, with "Essence" as the power stat, which affects what "Charms" (skill-based superpowers/spells) the character can take, and which is used to calculate the character's "motes" (magic points).
* In "standard" ''TabletopGame/{{GURPS}}'' magic, casting spells uses up some of the magic user's Fatigue Points, just like any other hard work, ''and'' can only be done in an area with [[BackgroundMagicField ambient magical force]], called "Mana". ''GURPS'' borrowed as much from Niven as ''D&D'' did from [[VancianMagic Jack Vance]]. Supplements have varied sorts of mana, even a type that is actively malevolent.
* ''TabletopGame/TheDarkEye'' uses "astral energy" in point form, recoverable by sleeping, meditation and extremely expensive mana potions.
* ''TabletopGame/CartoonActionHour'' avoids this by using Clusters, called Spell Clusters as wizard-type characters will be using them most.
* Averted in ''TabletopGame/{{Eon}}'' where magicians channel mana from the surroundings to produce effects. The effects possible are only restricted by how much mana you can channel and hold at one time. Mana is not a generic concept though, there are 21 different kinds of mana that have different uses, and two of those can't even be channeled by mere mortals. When there is one kind of mana you lack you could transform a suitable type of mana into the one you want.
* ''TabletopGame/InNomine'', has Essence, the energy of the universe, which is generated by most beings daily, and can be used by angels and demons, ethereal beings (beings generated by human dreams), and a few supernaturally aware humans to fuel [[MagicMusic Songs]] and sometimes other supernatural abilities, as well as to provide a boost to mundane actions. Ordinary humans spend their Essence unconsciously to boost themselves when they really want to succeed at something.
* ''TabletopGame/{{Rifts}}'' and other books by Creator/PalladiumBooks uses P.P.E, or Potential Psychic Energy. The name comes from an in-universe book written in the 1970s about magic. It's called Potential Psychic Energy because all people are born with a large store of it, but with the exception of magic users, almost all a person's P.P.E. disappears as it is used in the creation of talents and other things that define the person as an adult. Every living creature has some P.P.E. inside them, and magic users become living batteries able to store vast amounts. Inexplicably, a person's P.P.E. doubles at the moment of death; this is the in-universe reason for the use of sacrificial victims in connection with rituals. It's also the reason young victims are preferred, as a small child has 3-5x the P.P.E. an adult has.
* In ''TabletopGame/ConspiracyX'', magicians draw their power from the Seepage. You see, 95% of humans actually have psychic potential, but [[spoiler: since humans were created by the Atlanteans utilizing genetic material from three different species]] the vast majority cannot use even a fraction of it. The rest dissipates passively over time (and spills out in great amounts when great emotions such as fear or anger are experienced). This is the "aura" psychics can see. So basically, Seepage is the untapped psychic potential of the entire human race. [[spoiler: Unfortunately, since so much of it is the product of negative emotions, over the ages it has not only gained an alien consciousness of its own, it is actually malevolent. It actively seeks to cause fear and suffering to expand itself.]] It often manifests in explainable, "spontaneous" supernatural phenomena, and it causes people to go mad if they mess too much with it. Those who don't go mad may be transformed into vampires, werewolves, or other such monsters.
* The player characters of ''TabletopGame/{{Nobilis}}'' use Miracle Points, which conveniently abbreviates to MP. They get five in each of the four stats (Aspect, Domain, Persona and Treasure) and can buy more, and the rule is that you can only spend them in powers of 2 -- 1, 2, 4 or [[HeroicRROD 8 + wound]] points at a time -- to use miracles above the level of the stat in question. Of note, in Chancels, Nobles get a 3 MP discount on everything, making them ''really, really scary'' -- someone with Treasure 5 can pull off Imperial Miracles with a single MP and a bit of prep time.
* The first edition of ''TabletopGame/{{Ironclaw}}'' had magic points, but the current edition has a unique system of spellcasting with no hard limit on how many spells can be cast. It takes an action to prepare the spell, another action to cast the spell, and a third to refresh the spell before it can be prepared again, with some advanced spells requiring a more basic spell to be prepared first.
* ''TabletopGame/AnimaBeyondFantasy'' uses magic points named ''zeon'', that are gained and/or bought when your character levels up. In addition to it the game has also another stat, that shows how much zeon you can summon from your reserve each turn and is so critical as having many zeon points.

[[folder:Video Games]]
* In the ''Franchise/{{Lunar}}'' games, all special attacks, including KiAttacks use up the same [=MP=]. However, they do not all count as "magic" as defined by the series. This gets weird in ''VideoGame/LunarEternalBlue'', when Ronfar's healing spells are determined to be "not magic."
* The MMORPG ''VideoGame/CityOfHeroes'' uses Endurance to fuel all superpowers, whether they are magical, technological, the result of mutation or scientific experimentation, or plain ol' martial arts.
* ''Franchise/ShinMegamiTensei'' games have Magnetite, a mystical substance that makes up the physical bodies of demons when they are summoned; it is, unsurprisingly, produced most richly by human bodies and a critical need for the series' MagicFromTechnology. ''VideoGame/ShinMegamiTenseiIIINocturne'' has Magatsuhi, quite possibly related if not the same thing as Magnetite; large enough stockpiles of the substance are enough to recreate the world from nothing or utterly obliterating the cycle of life and death. It is very clearly shown that the effects of forcefully removing an individual's Magatsuhi is quite painful to the drainee and may have long-reach consequences, leaving the victim weak and despondent.
** Magnetite is usually only used for summoning demons, but in the second Raidou Kuzunoha game, it also functions as MP. Raidou can't cast magic, but his demons can, and they require Magnetite to cast it. It also functions closer to standard MP in how you recover it -- rather than requiring you to get it from a defeated enemy, you can rest and recover all of your Magnetite. You can also drain it mid-combat, which is useful for long, drawn-out battles.
* Since ''VideoGame/TheLegendOfZeldaALinkToThePast'', the ''Zelda'' series generally allows Link access to a [[ManaMeter Magic Meter]] in order to use magic powers, although it is not present in all games (''VideoGame/TheLegendOfZeldaTwilightPrincess'' being a notable example).
* The ''VideoGame/{{Ultima}}'' series uses a hybrid system in which casting spells does cost mana, but it also requires special ingredients called reagents to be cooked up into a usable spell. Certain spells in ''TabletopGame/DungeonsAndDragons'' use something similar, called "material components".
* Mana is a large staple of ''Franchise/{{Disgaea}}'' and later Creator/NipponIchi strategy [=RPGs=] as it is needed to create characters, unlock events, reincarnate, and so forth. Mana is treated in-game as a sort of currency. It also has SP for special moves and casting spells.
* ''VideoGame/MakaiKingdom'': Many of the characters often mention ow they can often feel mighty mana powers, and how much mana power any character has.
* All player characters in ''Videogame/KingdomOfLoathing'' have "MP" and it all works the same way. The twist is that what MP stands for is different for different classes. Mysticality (spellcaster) classes have mana points, but Muscle (warrior) classes have muscularity and Moxie (rogue) classes have mojo points.
* ''VideoGame/StarOcean'', where MP equates more to mental strength rather than magical energy. In ''VideoGame/StarOceanTillTheEndOfTime'', when you run out of MP, you get incapacitated (adding more to the mental strength fact) and that only Runology (magic) consumes MP. Killer moves consumes HP instead.
* ''VideoGame/{{Geneforge}}'' has essence, which functions in the same way, but is semi-living goo that can (and often is) stored outside of people's bodies.
** Also energy, which is used up faster by spellcasting but rapidly regenerates, and is not needed to make {{Mons}}.
* ''VideoGame/PaladinsQuest'', a RPG for the SNES, has no MP. All magic use is [[CastFromHitPoints tied to Hit Points]]. Healing, for obvious reasons, is not available as magic, and instead is in "bottles" which provide a character with a specific number of uses until they are refilled.
* In the [=GBA=] ''VideoGame/GoldenSun'' series, the heroes are masters of "Psynergy", a type of magic''/''PsychicPower. They encounter a martial arts school, and the head of the dojo comments on how their powers differ from KiAttacks. "Psynergy comes from the mind, while Chi comes from the body." It's commented that Psynergy is genetic, while "anyone" can eventually learn to use Chi, however [[WhenAllYouHaveIsAHammer nobody in the party does.]] However, there are ''Ki'' techniques (not Chi) from a different temple/dojo, with Psynergy substitutes that the heroes can learn.
* Most of the role-playing games in the ''Franchise/SuperMarioBros'' franchise use a Mana system for special attacks. ''VideoGame/SuperMarioRPG'' and the [[VideoGame/PaperMario64 first]] [[VideoGame/PaperMarioTheThousandYearDoor two]] ''VideoGame/PaperMario'' games use Flower Points, the [[VideoGame/MarioAndLuigiSuperstarSaga first]] and [[VideoGame/MarioAndLuigiDreamTeam fourth]] ''Mario & Luigi'' games use Bros. Points, and the [[VideoGame/MarioAndLuigiBowsersInsideStory third]] ''Mario & Luigi'' game uses Special Points. ''VideoGame/SuperPaperMario'', ''VideoGame/MarioAndLuigiPartnersInTime'' and ''VideoGame/PaperMarioStickerStar'' instead use inventory items as special moves.
* The ''VideoGame/WorldOfMana'' (''Seiken Densetsu'') series, naturally, uses it as the source of magic (and all life in general), with assorted spirits overseeing each of the elements, coming from TheWorldTree. How much is available depends on [[NiceJobBreakingItHero how active the heroes have been at breaking said tree]].
* The Plasmids from ''VideoGame/{{BioShock|1}}'' are powered by "EVE," which is mechanistically identical to mana.
** ''VideoGame/BioShockInfinite'' has Salts, which fulfill the same function.
* {{Franchise/Nasuverse}}
** Prana (the "energy" used to do magic) is separated between Odic force and {{Mana}}; the first is generated from the magus (small pool), and Mana is the energy in the environment (big pool). The two are essentially interchangeable, except for those rare occurrences where only Mana supply is affected. Higher Elementals are essentially ''made'' of Mana, similar to {{Energy Being}}s. How mana is gained and used are plot points of ''VisualNovel/FateStayNight''. LifeEnergy theft and IntimateHealing, primarily.
** In ''Literature/AngelNotes'', set far in the future of most other Nasuverse stories, mana is completely gone after the Earth itself died. What is left of the Earth's lifeforce has turned into some other form of energy known as "Grain", which is deathly toxic to everything except lifeforms specifically modified to tolerate it (or the Ultimate Ones, but then they're near-impossible to kill anyway). Grain can still be used as a power source, however, and both magic and technology make use of it (granted, the line between the two has blurred significantly by this point, and there may in fact be no distinction between them at all anymore).
* The ''VideoGame/AtelierIris'' sub-series does the same thing. Most alchemists are required to befriend mana spirits to improve the success rate of the items they create. The older ''Atelier'' games avoid this completely however; the alchemists simply make things like bombs without any outside "mystical" assistance, keeping with the LowFantasy feel of the setting.
* Licensed ''Franchise/StarWars'' games which feature Force use generally model it in a very {{RPG}}-ish fashion, with "Force powers" (spells) powered by "Force points" (mana).
* ''VideoGame/TalesOfSymphonia''. The characters spend a majority of the game trying to restore the mana flow to [[spoiler: both worlds, and eventually restoring the source of Mana, the Giant Kharlan Tree]]. In Symphonia life can't even ''exist'' without mana.
** The sequel [[VideoGame/TalesOfSymphonia Tales of Symphonia: Dawn of the New World]] also has a plot based heavily about mana.
*** As does ''VideoGame/TalesOfPhantasia''', which the ''VideoGame/TalesOfSymphonia'' duology is a prequel to.
* In '' VideoGame/TalesOfTheWorld'' Radiant Mythology series, mana is born from the World Tree and flows out into the world, providing it with life. Without mana, the world itself would die. The Descender is born from his/her world's World Tree, which uses its mana to give birth to a Descender. A Descender's power also fluctuates with the strength of mana and the World Tree it comes from. Although the Descender is incredibly strong regardless of how weak the World Tree is, it has been said that the stronger the World Tree's mana is, the stronger the Descender will be. However, it is mana which sustains the life and power of the Descender. In the most dire straits, a lack of mana in the land can adversely affect the Descender, leading to blackouts. The first Radiant Mythology has a story that focuses a lot on mana.
* ''VideoGame/TalesOfVesperia'' starts out with "Aer" [[spoiler: later revealed to be toxic. At the end of the game, Rita discovers a way to replace Aer with actual "Mana".]]
* Many ''Franchise/FinalFantasy'' games have mana, but there also are many exceptions. [[VideoGame/FinalFantasyI I]], [[VideoGame/FinalFantasyIII III]], and [[VideoGame/FinalFantasyVIII VIII]] use a mana pool. The games mentioned use a ''TabletopGame/DungeonsAndDragons''-style "uses per day" system, with VIII having some twists on the idea. The first game had its system converted to a mana pool in later remakes for ease of use. ''Videogame/FinalFantasyXIII'''s battle system is another exception, there is no MP in this game, either. Magic functions as it does in ''VideoGame/ValkyrieProfile'', essentially: An alternate form of attack with some charge times tacked on. III's system is labeled as MP though (at least in the DS version) and can be restored by an elixir as mana often can be.
* ''VideoGame/WorldOfWarcraft'': All classes except rogues, warriors, death knights, and hunters use mana. [[note]]Druids don't use mana when in certain forms, but they still have it.[[/note]] The previously mentioned classes tend to [[LeeroyJenkins forget this fact and rush into battle]] before the mana users are ready.\\
The aforementioned classes use resources similar to mana (rage, energy, runic power, focus), but with two main differences: First, the maximum amount you can have and the rate of regeneration don't scale with level and gear. Second, whereas mana regenerates more slowly if at all during combat, energy and focus regenerate at the same rate in and out of combat, and rage and runic power actually drain when you're not in combat.
** Energy and Focus regenerate during combat, with Focus having an attack to replenish it faster (Steady Shot and Cobra Shot). Rage and Runic Power are gained by either hitting mobs or letting mobs beat on you.
* ''VideoGame/EveOnline'' has a capacitor for ships, which is used to activate all the equipment on a ship with the exception of projectile weapons. The capacitor is drained by a certain amount with each activation, and has a base regeneration rate, which can be enhanced with a multitude of skills and ship fittings. As in World of Warcraft, one of the most important duties for any pilot is to find a balance that won't completely drain the capacitor, leaving the ship helpless while it regenerates.
* ''VideoGame/TheReconstruction'' has three stats that different abilities can be cast from, of which Mind and Soul would correspond to different types of Mana. Interesting, not only is it just as frequent to CastFromHP, Mind and Soul function as alternate HP counters, and dropping one of them to 0 will also defeat someone.
* Power Points (PP) in ''Franchise/{{Pokemon}}'' function like mana. However, it's different from most examples in that each move has its own set uses of PP rather than all moves drawing from one pool of it.
* ''VideoGame/KingdomHearts I'' and ''II'' have MP, with every spell taking up a certain amount or fraction of the MP in the meter. This was recharged in the first game by physical attacks, and by collecting MP Orbs. The second game had an MP meter that could be refilled by MP orbs as long as it still had some MP in it, but once it was all used up, you had to wait a short time for it to refill completely before you could use any spells. This could be sped up by collecting MP Orbs. Both games also had items that refilled MP, and abilities that gave other conditions for getting MP.\\
The other games employed variations on Vancian Magic, forcing you to stock the spells you thought would be most useful ahead of time.
* Pretty much all {{Roguelike}} games use some mana-type system which spell casting and psionics use, with mana regenerating over time. In the few games where the player could gain different [[ReligionIsMagic divine powers]] by worshiping different gods there's a separate pool of "faith" or "piety" points which are expended to use those powers, with each religion having a different method of regaining points.
* Nono from ''VideoGame/{{Solatorobo}}'' is something of a combination of mana and [[StarWars The Force]]. While it can be used to produce magical effects such as [[BarrierWarrior barriers]] and levitation, being attuned to it also results in being able to sense other people or objects who are tapping in, such as the Paladins and the [[MacGuffin amulet]].
* Crest Magic users from the ''VideoGame/WildArms'' series are all [[BigEater Big Eaters]], and they claim that casting spells uses a lot of energy. This results in the often scrawny or waiflike magic users consuming truly prodigious amounts of food (Celia in the first game at one point orders more food than should actually be able to fit in her body). The first game does use MP however, for two of the characters, and thus it might be that the fuel used for magic is perfectly normal bodily energy, as the other user uses his MP to fuel his various sword techniques. This makes a bit more sense when you realize [[spoiler: that the only character who doesn't have MP, Rudy, is actually a RidiculouslyHumanRobot.]] Later games do away with traditional MP, but the implication that Crest Magic users burn lots of energy and eat lots of food remains.
* ''Franchise/TheElderScrolls'':
** Referred to as "Magicka" throughout the series. It is said to flow in from [[SpiritWorld Aetherius]] through the sun and stars, allowing mortals on Mundus (the mortal plane) to use magic.
** Mechanically, each spell has a casting "cost" of Magicka. The spell's power, AreaOfEffect range, and duration all contribute toward the calculation of the Magicka cost per cast. Through ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'', your maximum Magicka is equal to your Intelligence attribute, with multipliers based on your race and birth sign. Starting with ''Oblivion'', it also regenerates on its own based on your Willpower attribute. ''Oblivion'' also changed the cost of casting a spell based on your Skill Level in that spell's governing skill. (For example, you have [[ElementalPowers Destruction]], [[SummonMagic Conjuration]], [[WhiteMagic Restoration]], [[UtilityMagic Alteration]], [[MasterOfIllusion Illusion]] and [[RealityWarper Mysticism]] skills. As you get better in each by casting spells of that type, casting those spells gets cheaper.) Luck also plays a part, as it does in everything. ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' revamps the system almost entirely, first by removing attributes (you can instead choose to add +10 to your Magicka pool with every level up) and then by adding Perks in the skill trees of the governing skills for spellcasting.
* ''VideoGame/{{Darklands}}'' has "divine favor" points (DF). They are spent when a character prays to saints for miracles and are slowly regenerated over time. To regain DF faster a character can spend the day praying for divine favor instead of working or studying.
* ''VideoGame/{{Diablo}}'' and its successors use a mana system, although in ''VideoGame/Diablo III'' different classes have different names for it.
* In ''VisualNovel/AnOctaveHigher'', Mana is the common name of a liquid substance that, when drunk, gives human beings the energy needed to cast spells. It is also known as ''curcuma zanthorrhiza'', or ''temulawak''. People can also replenish their Mana by sleeping, exercising and eating food, but not by much; certainly not enough to cast spells.
* In ''VideoGame/TreeOfSavior'', mana is referred to as the power to change divine grace into other forms. The Cleric and Wizard class families are said to use this in order to work their miracles and magic. However, the actual "mana" game mechanic is referred to as SP, similar to ''VideoGame/RagnarokOnline''--and that covers ''all'' skill usage, including the non-spellcasting Archer and Swordsman class families.
* ''Creator/FromSoftware''
** ''VideoGame/DemonsSouls'' and ''VideoGame/DarkSoulsIII'' follow the traditional Mana system to a tee, however the source of Mana is in fact [[SoulPower Soul Art]].
** ''VideoGame/DarkSouls'' and ''VideoGame/DarkSoulsII'' replaces the Mana system by having magic as ammunition based, and recharges via resting at bonfire.
** ''VideoGame/{{Bloodborne}}'' completely averts this trope by having all spells cast via ''literal'' ammunition. In order to cast a spell, the Hunter injects their blood-infused Quicksilver Bullets into the medium, the Phantasm, which are leftover from the [[EldritchAbomination Great Ones]]. It can be considered as a combination of BloodMagic and SummonMagic.
* ''VideoGame/OriAndTheBlindForest'' uses Spirit Energy for creating [[SavePoint Soul Links]], executing {{Charged Attack}}s, and opening Energy Gates. Energy Cells increase the capacity of the ManaMeter.

[[folder:Web Comics]]
* Lux in ''Webcomic/TalesOfTheQuestor'' is a bit light on ritual, but otherwise fits the spell-casting thing pretty well. WordOfGod says lux is more akin to a really funky neutrino field than typical magic. Most of the populace treats it like magic, though, and it can summon lightning bolts.
** The similarity to magic is actually a plot point a few times, though mostly in the filler arcs. Although the Racconans know that lux is a science and doesn't depend on witchcraft, rituals, or deals with the devil, most humans (living in a feudal-type society) are ignorant of this, making them treat lux-users as dangerous outcasts and associating them with others who claim to perform magical feats--like the human-sacrificing druids. It doesn't help that very few humans are born with the ability to channel lux. (Although those who are born with it are implied to be generally far more powerful than the best of the Racconans.)
* In ''Webcomic/{{Drowtales}}'', drow call the substance that powers their FunctionalMagic [="=]{{Mana}}[="=]. In fact the author rather objects to the term [="=]magic[="=]. Not only is it generated by the elves' own LifeForce, it is necessary to allow the fey races to remain immortal.
** Eventually this is split into 2 distinctive forms: '''ether''', generated by fae races and some types of plants, and '''nether''', commonly known as demonic energy, imported from portals to netherworlds or created by demons and [[SymbioticPossession tainted individuals]]. For some reason, nether is far more powerful than ether (a nether bolt attack goes straight through an ether energy shield) and nether creatures devour ambient ether like candy.
* ''Webcomic/TwoKinds'' has normal Mana, which is used for mainstream magic and will crystallize into a [[GreenRocks little blue rock]] when concentrated, and Dark Mana, which is actually TheLifestream used in place of mana, and allows summoning and necromancy (which usually doesn't work). It causes crystals to form as well, but this is simply a side-effect. Dark Mana causes brain damage, insanity and death.
* Izzy from ''Webcomic/AdorableDesolation'' has the ability to map mana trails.
* In ''Webcomic/TheDragonDoctors'' it's possible to go into "Mana Shock" when you accumulate too much; this happens to a girl who was turned to stone and left soaking in the bottom of a leyline for 2000 years. She nearly exploded when she went into Mana Shock later.
* An unusual example in ''Webcomic/{{Housepets}}'', [[JerkassGods Pete]] and the Spirit Dragon are near-omniscient, but in regards to their [[CosmicChessGame game]] they limit their powers by making them cost "mana", which is accumulated at their temples.
* ''Webcomic/IrregularWebcomic''. [[EarthShatteringKaboom "Channeling mana..."]]
* In ''Webcomic/ElGoonishShive'', everyone has access to latent magic energy which they can use to cast spells if they have access to the spells in question and have enough magical energy built up. Very rarely, individuals are born who have [[MuggleBornOfMages no potential to gain the capacity for more magical energy]] beyond their innate latent magic energy.
* ''Webcomic/{{Kubera}}'': "Vigor" is a general personal energy used to cast spells or use magic items, but different entities regenerate it in different ways.
** Gods have incredibly high amounts of Vigor, but the rules were changed after a recent and devastating war, so gods can no longer access their full power in the mortal realm. Instead, they are limited to using the Vigor of their summoner, and they can very easily kill the summoner if they are not careful. The death of their summoner means they are sent back to the divine realm.
** [[OurDemonsAreDifferent Sura]] also have incredibly high Vigor reserves, but their natural rate of regeneration is so low as to be practically nonexistent. Instead, they only regenerate Vigor by devouring living creatures--both humans and [[ImAHumanitarian other sura]]. They don't need to eat otherwise. In fact, a common trick in sura combat is to devour an opponent's eyes or other valuable body part, as something that has been devoured and turned into Vigor is very difficult for a sura to regenerate with their otherwise overpowered HealingFactor.
** Humans have very low amounts of Vigor, which puts a noticeable cap on their power. Their Vigor regeneration is normally reasonable, but it depends on their mental state. Being worried and tired reduces their regeneration rate, while being rested increases it. It has also been noted that if their mental state is ''exactly right'', their Vigor regenerates so fast that it becomes essentially infinite, allowing them to cast spells or use magic items that would normally kill them.

[[folder:Web Original]]
* Mana in the main series of ''Literature/ArcanaMagi'' is treated as a form of energy, with two types, kinetic and potential, that is used by magical people to cast spells and activate magical items. Mana is common now in ''Literature/ArcanaMagiUniverse''.
* Aura in ''Literature/ChaosFighters''; using it effectively requires charging, i.e. accumulating it into something. However, aura are ''atom sized particles'' and in-universe it is partially explained using ''quantum mechanics'' and partly using ''classical wave theory''.
* Mystic power in ''Literature/{{Phaeton}}'' is sometimes called mana or something like that to save time and is used in the same way.

[[folder: Western Animation ]]
* In ''WesternAnimation/{{Ben 10}}'' we are led to believe that Gwen's powers are purely magic-based, but ''WesternAnimation/Ben10AlienForce'' starts DoingInTheWizard by explaining that Gwen's powers originate from an alien grandmother, who states that 'magic' is caused by mana. If that wasn't enough, the granny then sheds her skin to reveal an energy being made of mana, and says that Gwen can do the same. Naturally, she refuses.
** Eventually, they go for an interesting blending of [[DoingInTheScientist the former 'magic' explanation and newer 'alien powers' explanation.]] Magic is mana manipulation, and being part mana-made energy being makes you really ''good'' at it. Grandma Verdona's powers and 'magic' powers are different ways of using the same thing and Gwen is learning both (around this time, she starts to use spells like she did in the original series ''as well as'' the GreenLantern-lite powers that had replaced them when Alien Force began.) Charmcaster and Hex, the magic-based villains, on the other hand, come from another dimension where all mana comes from: Ledgerdomain is a dimension where [[AlienGeometries 'the sky isn't parallel to the earth']] so you might get lost forever if you try to fly, and it's a PlanetOfHats whose hat is wizardry. Charmcaster is sort of jealous that Gwen is able to easily pick up what it took her years and years of study to learn.
* ''WesternAnimation/JackieChanAdventures'': Uncle's and Dao Long Wong's "Chi Spells" seem to be HermeticMagic with an eastern flavour. How Chi is distributed is a major part of the plot throughout the seasons.
