->'''Mana Burn'''
->''3 sec cast''
->''Cost: 14% of base mana''
->''Destroy 10% of the target's mana (up to a maximum of 20% of your own maximum mana). For each mana destroyed in this way, the target takes 0.5 Shadow damage.''
-->--''VideoGame/WorldOfWarcraft'', later removed from the game.

An attack or ability that damages the ManaMeter of the victim. Other secondary effects may come in to play, but this is the ability's primary purpose.

A fighter-type character capable of this trope and well more than always capable of spamming it in a very short time will be able to remove a SquishyWizard anytime.

See also ManaDrain and ManaShield.

!!Examples:

* Multiple times in the ''Franchise/FinalFantasy'' series
** ''VideoGame/FinalFantasyVI'' has Rasp. Interestingly, some enemies and even a few bosses can be killed by rasping away all their MP.
** Magic Hammer is a reoccurring [[MegaManning Blue Magic]] spell that switches between this and ManaDrain depending on the game (in ''VideoGame/FinalFantasyVII'', it drains).
*** Also, Barret's second lv1 LimitBreak.
** In ''VideoGame/FinalFantasyTactics'', the Bizen Boat release drains MP from surrounding enemies. Oracles may drain MP as well.
** ''VideoGame/FinalFantasyTacticsAdvance'' has Magic Break, Manastrike, and Soul Sphere on top of those mentioned already.
*** And Damage -> MP, which changes HP Burn into Mana Burn.
** This is a side effect to the [[UniversalPoison 'Venom']] status effect in ''VideoGame/FinalFantasyIX'', as well as rendering the afflicted character unable to act.
** Manticores in ''VideoGame/FinalFantasyXI'' can indirectly perform a ManaBurn by using Riddle, which lowers max MP by a significant amount. You definitely don't get the MP back when it wears off.
** Many enemies in ''[[VideoGame/FinalFantasyX2 Final Fantasy X-2]]'' have abilities that target your party's MP, and likewise your party can do this - either by burning it or draining it. Specific examples are the Gunner's "Target MP" and "Quarter Pounder" abilities.
* ''VideoGame/BravelyDefault'' has Soul Crush, one of the Valkyrie's abilities, which destroys an enemy's MP equal to 10% of the damage a normal attack would do. Of course, since [[TheComputerIsACheatingBastard the enemies never seem to run out of MP for their spells and other abilities anyway]], [[UselessUsefulSpell this isn't very useful]].
* In ''VideoGame/ChronoTrigger'', the party member who attacks Flea's blatant decoy has their MP set to zero, and you ''have'' [[StupidityIsTheOnlyOption to attack it to call Flea out]].
** The attack is called "MP Buster", and the false Flea is not the only one who can use it.
* Certain baddies in ''VideoGame/TheLegendOfZeldaALinkToThePast'' dungeons drain mana from your meter when they hit you.
** Glowing floating skulls were actually introduced in ''VideoGame/ZeldaIITheAdventureOfLink''. There, they were ''much'' worse, as Link has exactly no items, and all his extra-super powers required mana to use. In addition, the skulls did ''just'' enough damage that if you had full life to use the sword beam, you couldn't anymore. They could be killed and gave a lot of XP for early dungeon enemies, but they required a ''lot'' of hits, even with the highest attack power.
** ''[[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker]]'' featured tentacle-hands that would grab you and drain your magic (which would gradually regrow), as well as floating skulls that when touched, prevented you from using any items. Which of course were the only thing that could kill them.
* ''Videogame/EarthBound'': "The Mad Duck made something spin around!"
* Flower Fuzzies in ''VideoGame/PaperMarioTheThousandYearDoor'' suck out a few of your FP and can use them for a lightning attack.
* ''Videogame/{{Pokemon}}'' gives us Spite (which drains PP from the last move the opponent used), Grudge (drains all PP off the move that KO'd the user) and the passive ability Pressure (doubles opponent's PP use).
* ''Videogame/MarvelUltimateAlliance'' and the ''{{X-Men Legends}}'' series have enemies whose presence drains away characters' EP.
* In ''VideoGame/WorldOfWarcraft'', Priests and some enemies have an ability called Mana Burn, which removes the target's mana and then deals damage equal to half the mana lost.
** Hunters and Warlocks also used to be able to affect enemy mana (but the latter used a ManaDrain for it) while Human Priests had an additional ability named Feedback (based on a ''Warcraft III'' passive ability that causes attacks to burn some mana), but all three were eventually removed entirely.
** In ''VideoGame/WarcraftIII'' the demon hunter has the mana burn ability, which damages the target's mana and damages the target's health by the amount of mana lost, not very pleasant if the target hero is a caster or worse, a mana-based tank.
* ''[[VideoGame/{{Diablo}} Diablo II]]'' has the "Mana Burn" stat that can spawn on unique monsters, which takes some of your mana when they hit you. There are also regular monsters with mana draining attacks. Encountering a monster with both Mana Burn and [[DemonicSpiders lightning enchanted]] is [[VideoGame/DwarfFortress fun]].
* In ''MagicTheGathering'':
** Any ability that destroys and/or taps lands is effectively this trope; a particularly good example of this is [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=194671 Roiling Terrain]], which destroys a land, then deals damage based on how many lands have been destroyed in total (while also punishing the use of fetch-lands, but that's a topic for another trope).
** Closer to the true meaning of this trope, there's [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=25567 Mana Short]], among others.
** In ''Literature/AgentsOfArtifice'', Paldor's manablade can sever mages' mana bonds, cutting them off from the source of their magic (and causing intense pain).
** There's also the now-obsolete rule of "Mana Burn", where if you have unused mana at the end of your turn (i.e. you tapped lands but didn't cast anything with them), you take damage to your life equal to the amount of mana unused, as it "burns" you. Since the rules allow you to tap land as you need it, [[IdiotBall the mana burn rule rarely, if ever, comes up]]. The rule was dropped in the 2010 Core Set release for being unnecessary 99% of the time and annoying the remaining 1.
* ''NetHack'' has the anti-magic trap. Takes some mana from the player unless he's magically protected.
* ''KingdomOfLoathing'' has countless of these.
* ''{{Starcraft}}'' has the Science Vessel's EMP, which drains all energy and shields. Dark Archons have a feedback ability, which causes literal Mana Burn, the enemy unit takes damage equal to lost energy. Which leads to a 1-shot-kill against targets with more mana than hitpoints.
* Fubuki's passive ability in ''VideoGame/{{Disgaea 2|CursedMemories}}''.
** Later, an evility possessed by the Reaper class in ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'' and ''VideoGame/{{Disgaea 4| A Promise Unforgotten}}''.
* Some enemies in the first ''ManaKhemia'' game do this.
* Some abilities do this in the ''DragonQuest'' series. "Strange Dance" for example.
* ''RagnarokOnline'''s "Soul Burn" skill depletes the enemies SP completely. If you have the skill on max level, it additionally damages the opponent with his depleted mana x2.
* Treasure Chests in ''VideoGame/{{Persona 4}}'' sometimes contained traps which halved your SP.
* ''VideoGame/WarcraftIII'' has the ManaBurn spell and the Feedback ability. Both destroy mana and an equal amount of health.
** The whisp's self-destruct ability destroys mana, and can damage [[SummonMagic summoned units]].
* Many abilities in ''VideoGame/StarOceanTillTheEndOfTime'' do this in addition to causing normal damage, the reason being that you can be [[NonLethalKO knocked out]] if you run out of [[ManaMeter magic points]] just the same as you can be knocked out for running out of HitPoints.
* ''CityOfHeroes'' has the [[GoddamnedBats Sappers]] of the Malta Group -- a well-known annoyance, especially for Tanks and other archetypes whose strengths are based around powers that require a regular flow of Endurance and stop working once the meter's drained.
** Players also have access to Mana Burning abilities, particularly [[ShockAndAwe Electric Themed Powersets]]. A Kinetics/Electrical Blast Defender can render enemies helpless if she knows what she's doing. An Electric/Electric Blaster is even better at it.
** Other enemies, such as the [[CircusOfFear Carnival of Shadows]], have similar attacks that can drain your endurance, or stop you from regenerating it.
*** At least players with Electric Armor can get the last laugh, having gained 90% resistance to endurance draining powers by the level that the above enemies start appearing at.
* ''Franchise/TheElderScrolls'' games tend to have mana draining and mana transfer spells but not yet anything that uses mana as hitpoints. Additionally, an interesting gameplay quirk of ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]'' is that if you absorb too much [[CallAHitPointASmeerp magicka]] over your limit you can ''die''.
** However, in ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', there's a spell called "Equilibrium" that converts your HP into MP. This is very exploitable, as it allows nigh-infinite grinding of the Restoration skill if the caster is also casting a healing spell at the same time.
** [[ShockAndAwe Shock elemental]] Destruction spells deal damage to the target's Magicka as well as Health, making them ideal for combating other spellcasters.
* ''VideoGame/TitanQuest'' has a few skills pertaining to this, along with some rare and very useful weapon bonuses that drain a portion of an enemies energy with each strike. Very useful when fighting powerful mooks. Stacking these effects from multiple items makes the energy burn deal absurd amounts of damage.
* ''DefenseOfTheAncients'' Nerubian Assassin has the Mana Burn nuke. Anti-Mage has a passive that drains mana with each attack. Keeper of the light has a debuff that drains mana based on distance moved. Obsidian Destroyer has a disable that steals Intelligence and his ultimate burns mana or deals damage based on the amount of Intelligence that an enemy hero has. Diffusal Blade is an item that gives the passive to any hero.
* ''HeroesOfNewerth'' Magebane has a manaburn passive attack and Nullfire Blade gives gives this passive to any hero.
* [[MageKiller Templars]] in ''VideoGame/DragonAgeOrigins'' can drain an enemy mage's mana with each of their attacks after learning the "Righteous Strike" passive talent. Mages themselves can learn "Mana Clash", which has the double whammy of completely draining enemy mages' mana ''and'' dealing damage proportional to the amount of mana lost. It's so powerful it can kill most boss-level magic-users with one or two hits [[spoiler: even Gaxkang]].
* ''EveOnline'' has energy destabilizers (usually called neuts) that empty some of the target's capacitor at the cost of a smaller amount of your own capacitor. Ships that specialize in this such as the Curse and certain Dominix setups can be particularly fearsome in solo/small group PVP.
** To be more specific, there are many powerful defensive setups a player can use on his ship, but the most effective ones are completely dependent on his ship's capacitor. Using enough energy neutralizers on him will turn him from a MightyGlacier into a very easy kill indeed.
* A non-video game example: In ''{{Mistborn}}'', Vin is captured and forced to burn a strange metal [[note]]revealed to be aluminum in the second book[[/note]] which drained her other metal reserves.
* In ''VideoGame/MagicalGirlLyricalNanohaAsPortable The Battle of Aces'', the held down version of Chrono's Struggle Bind will bring his opponent's MP down to zero in addition to restricting them.
* [[GoldenSunDarkDawn Tuaparang psy grenades]] pretty much do this. If you're lucky, you might get one of your own to use against them.
* Certain Charms can do this in ''{{Exalted}}'', i.e. the [[TheUndead Abyssals]]' Splinter of The Void. It can be upgraded into ManaDrain.
** Essence-Igniting Nerve Strike from Fire Dragon Style is a very mean bad-touch effect that deals damage equal to your enemy's Personal Essence pool, maxing out at twice your Essence stat. This can be ver mean, especially since it bypasses armour, but becomes hilariously unhelpful against Alchemicals, who typically don't have much of a Personal Essence pool because of how their Charms work[[note]]they have to manually install them, and most of them require a commitment of Personal Essence to run. A combat-specced Alchemical likely has no personal motes whatsoever and does everything with his peripheral pool[[/note]].
** Cecelyne's Stone-Flayer Touch destroys Essence in equal amount to health damage inflicted. It also hurts gods and demons, even if they are dematerialized.
* ''{{Arcanum}}: Of Steamworks and Magick Obscura'' uses "Fatigue" as mana. Blunt weapons, such as hammers and maces, do fatigue damage, effectively draining mana from mages while knocking them unconscious. A variety of other items have similar effects.
* Neji's Byakugan works this way in the ''Manga/{{Naruto}}'' fighting games.
* Certain monsters in ''VideoGame/MightAndMagic'' have a chance of removing a character's spell points when attacking (it is actually referred to as drain if you look into the files, but the monster doesn't get the spell points).
* ''GuildWars'' has Mesmers, who are masters of this trope. They have many, ''many'' ways to inflict this on enemies, so much that it becomes a valid strategy to completely deny your enemy any mana at all, rendering him effectively useless while the Mesmer is free to pound away. Some examples include but are not limited to:
*** Energy Burn/Energy Surge, both of which are typical ManaBurn attacks, only with the added effect that the number of mana burned is multiplied, then dealt to the enemy's health. Doesn't hurt that the damage from these skills are also ArmorPiercing.
*** Spirit Shackles: A particularly annoying skill which chips away at the target's mana every time he attacks. A careless victim can easily find himself with ''no mana at all'' in very short order.
*** Energy Tap/Energy Drain: Textbook ManaDrain attacks used for energy management as well as annoying your enemy.
*** Ether Lord: A rather bizarre skill that first empties the caster of ''all'' mana, then rapidly drains the enemy's mana while filling up the caster's mana.
** Rangers have the Debilitating Shot skill, the sole purpose of which is to deal a large chunk of mana damage to the target.
** Necromancers have the Wither elite skill, which drains both the target's health and mana. However, since mana constantly regenerates, it effectively just stops their regeneration, or at least slows it down (depending on the class and amount of natural regeneration you get).
* In ''[[NintendoWars Advance Wars: Dual Strike]]'', Sasha's CO Power drains her opponent's CO Gauge, which is required to perform a CO Power.
