A subtrope of Mana Burn
- a power that drains someone else's Mana Meter
and gives it to the caster. Useful both to replenish the user's mana and to prevent the enemy from being able to attack back. Some opponents die
when they lose all their mana.
When this is done to Hit Points
, it is Life Drain

- Naruto encounters several enemies who have the ability to drain chakra, most notably a spy of Orochimaru's who actively absorbs his enemy's chakra though his palm (he fights and loses to Sasuke in the preliminary of the Chunin exam).
- The Juubi's roots have the ability to instantly absorb chakra when it transforms into its God-Tree form. Kaguya has the same ability through touch and her minion.
- Zaraki's Power Limiter eyepatch works by feeding on his reiatsu.
- Yumichika's zanpakuto's true form can drain his enemy's reiatsu for, essentially, an instant win.
- A machine in later episodes of Magical Project S is capable of this on a mass scale.
- Many characters in Dragon Ball Z can absorb ki from attacks. Android 20, a.k.a. Dr. Gero, once suckers Vegeta into using an extremely powerful attack to obliterate his hiding place, only to zip out and slurp it up through his hands before it hits.
- This is played with later in the Buu story arc. Goku fights Yakon, a creature on Babidi's ship that drains his power whenever he turns Super Saiyan. He destroys it by turning Super Saiyan 2 for a very brief moment; the sudden influx of energy is too much for the creature's body and destroys it.
- Negi Springfield of Mahou Sensei Negima! in his dark mode does this using black flames.
- To be more specific, he only does this after absorbing a specific spell — "Hell's Conflagration".
- In Black Clover, Asta's Black Clover Grimoire summons Anti-Magic swords that drain mana on contact. This makes them extremely dangerous for anyone but Asta (who has no mana at all) to wield.
- In Kono Subarashii Sekai ni Shukufuku o! Wiz, a Lich, and Kazuma have the "Drain Touch" ability, which allows them to drain mana and/or HP, as well as transfer it to others.
- In the Enchanted Forest Chronicles, this is how all wizard magic works: their staves automatically draw in magic from the environment and store it to be used in spells. The effect is normally limited to close proximity, but can be expanded greatly for a short time. It also causes a severe allergic reaction in magical creatures such as dragons, and probably worse with long exposures.
- In Kamen Rider Wizard, the title character finds Wiseman's hideout, only for Wiseman to drain the energy from Wizard's Super Mode and use it first to blast him away, then to reinforce the illusion spell that protects the hideout.
- The color Blue in Magic: The Gathering has a host of such spells, as pictured above. Three such spells are Drain Power, Mana Drain and Mana Short.
- Mana Drain was so overpowered that Mark Rosewater, head of R&D, famously stated that the entire R&D team would have to be hit by a bus before they'd reprint it. They did eventually print a heavily nerfed version, Scattering Stroke, as a Continuity Nod.
- Steal Energy in GURPS is a highly restricted version of this.
- Power Leech, a psionic power from Dungeons & Dragons, allows a Psion to slowly drain power points from other psionic characters, although only a fraction of the drained points are added to the attacker's reservoir.
- There have been, over the editions, several different ways of roughly approximating this trope within the context of a basically Vancian magical system. One example is the 3.5 spellthief, which can forgo doing extra damage with its sneak attacks and instead steal a spell from the target, which can then be cast by the spellthief.
- The "Mystic Hunger" Consequence in Kitsune: Of Foxes and Fools causes the fox who drew it to try and steal the foxfire from another fox. However, they have a chance of failing and losing all of their own foxfire.
- Final Fantasy:
- Most games have the Osmose spell. More useful for replenishing the caster's MP than removing the target's (it's usually easier to just kill them), but it's very useful for the former. It usually only costs 1 MP and can obviate the need for MP-replenishing items altogether. And since MP can easily be converted to HP by way of healing spells, this also makes it trivial to get the party back up to fighting strength between battles.
- The Blue Magic Magic Hammer occasionally works this way, but usually just lowers the target's MP.
- Celes of Final Fantasy VI has the Runic ability, which is a reactive Mana Drain: when active, all magic cast automatically targets her, and she gets MP equal to the cost of the spell without getting damaged.
- Magic Hammer pulls triple duty in Final Fantasy XI, what with not only draining MP and giving it to you, but causing HP damage as well. Blue Mages can only learn it at level 74, however. There's also Aspir Samba, which Dancers use to let party members drain an enemy's MP.
- There's also White Draw, a Dragoon skill in Final Fantasy IX. It drains MP from an enemy and splits it among all the current party members.
- Final Fantasy VIII has the draw command, which lets you pull spells out of the enemies' bodies to replenish your own stock. Beware, however; some enemies, such as Ochu and The final boss can mana drain you.
- In Final Fantasy Tactics A2, spells are kept from being overly powerful by MP starting at zero and regenerating 10 each turn. For this reason, Osmose's straight MP drain would be too powerful when used by a mage class, and we instead get the Arcanist class's "Syphon" spell which drains the opponent's MP and restores an equal amount of the casters HP. The Lanista attack "Sword of Light" still does this conventionally, probably because Seeq don't have a lot to spend MP on.
- Final Fantasy X has Osmose found in Wakka's Sphere Grid. If taught to your dedicated Black Mage (usually Lulu), it facilitates near game-breaking spamming of Flare and/or Ultima. Especially since you can pull the MP from allies if you want.
- Bravely Default has the Aspir magic spell (the normal Black Magic spell as well as the Sword Magic variant) and the Vampire's Magic Drain ability.
- Ragnarok Online has an interesting example with it's Soul Change skill. Instead of just draining mana it swaps the mana pools between the caster and his target. As a result it can also be used to replenish allies mana using your own.
- City of Heroes has all sorts of endurance drain powers. On the critter side, the Malta Sapper has the most obvious and drastic (half your total Mana Meter in one hit), though there are others (Arachnos Mu are less powerful than Sappers, but much more common). On the player side, Power Sink, Transference, Short Circuit, Energy Absorption, every Electrical attack, and most of the Kinetic ones.
- Mana Drain from Shin Megami Tensei III: Nocturne. Life Drain and Daisoujou's Meditation are buffed versions of this that also steal HP.
- Digital Devil Saga changes the name to MP Drain and reclassifies it from Almighty to Mute. Knowing this makes one Bonus Boss, Orochi, much easier if you have Null Mute.
- The Lord of the Rings Online has the Loremaster player class, which can drain power from opponents and pass it to teammates. Certain enemies, such as the undead, can apply disease debuffs which drain your power.
- Some of the Dragon Quest games have enemies doing a "strange dance" which lowers one's mana. This was referenced in the baseball episode of Haruhi Suzumiya ("Is Haruhi trying to lower the pitcher's MP?").
- Dragon Quest IX: wands allow the user to do this with a normal attack. Of course, since they're mostly used by the Squishy Wizard, you'll drain maybe one or two MP at a time.
- A couple of heroes can perform this dance as well. Taloon from Dragon Quest IV, for example, does this at random times.
- The Blood Mage in Warcraft III: The Frozen Throne has an ability called "Siphon Mana". This can also be used on allies, draining mana from the Blood Mage into the ally.
- In World of Warcraft, shadow priests have this ability. They also have Mana Burn, which drains the victim's mana and hurts him by the same amount at the same time.
- Mages can do this to themselves, sort of; Mana Shield will cause them to lose mana instead of health when struck.
- Lady Deathwhisper, a boss in Icecrown Citadel, starts the fight with a mana shield which gradually drains her mana as you chip away at it. You can't even begin to hurt her until her mana pool is exhausted.
- In EverQuest, Necromancers and Enchanters are masters of this trope. Actually, Enchanters are mostly obeying this trope in raids. They rarely use their (otherwise totally inoffensive) damage spells, but they use all their versions of Mana Drain (one of them even named that). Similarly, Necromancers do this, and their inversion: Mana Pump.
- "Mana Drain" is one of the many spells in the Warlords Battlecry series. Also, an electrical attack will drain mana as a side effect on a critical hit. Both of these only empty the mana meter of the enemy, it doesn't steal it.
- Guild Wars characters have access to a wide variety of mana-draining skills. Ironically, the similar abundance of mana-boosting skills (especially the Necromancer's powerful Soul Reaping ability), coupled with the fact that most of the monsters are oversupplied with mana to begin with, has led to mana-draining skills being widely thought of as underpowered and pretty useless.
- Star Wars: Jedi Knight: Jedi Academy has "Force Drain" as a dark power (it was also available in the predecessor Jedi Outcast, in multiplayer only).
- If it's used on you, once you run out of force power, it starts draining your health. Really powerful bosses can kill with it.
- Similarly, Knights of the Old Republic II also had "Force Drain" as a Force power you could choose, but as you ran into maybe a dozen Force-using enemies in a game it was largly worthless. It's only real use is if a Light Side player wishes to use a certain Good Bad Bug for infinite experience, since it occurs in a place where force points can not be regenerated.
- Super Robot Wars has the Energy Taker, which does exactly what the name implies.
- The Snow Clan of the Disgaea series does this as their class ability. Fubuki does this directly while Yukimaru has the Hyuuga clan variant (physical attacks have a chance to inflict amnesia which disables use of special attacks).
- In the MMORPG Anarchy Online the trader profession has powerful abilities that drain other players nanoenergy (mana in the scifi game)in pvp combat, leaving many professions crippled.
- This was one of the ways you filled your Mana Meter in Silhouette Mirage, a PSX platform shooter. Facing one way would make you fire either life- or mana-draining bullets, depending on which kind of opponents they were. Facing the other way reversed them. Very 2-d of the game. Of course, if you didn't want to turn around you could burn 1/3 of the mana meter with a special reversal move.
- In Puzzle Quest: Challenge of the Warlords, the game itself performs a "Mana Drain" on both you and your opponent when there are no more available moves.
- Titan Quest features several random weapon properties and a skill or two that damages mana.
- The MOTHER series of games features "PSI Magnet α/Ω". Both moves are free, alpha drains from one target, and omega drains from all enemies. The catch is that the enemy has to actually be able to use PSI in order for PSI Magnet to drain PP. Fobbies are great for this, because they attack in large numbers, but start with a status effect that prevents their PSI from working. Just don't overdo it, because it'll really hurt when that status effect wears off.
- Present as a Mage spell in Nox, and notable for how it can drain mana over time both out of living beings as well as mana crystals and pylons.
- The Shin Megami Tensei series has Mana/Spirit Drain, depending on the game. Very useful in the SMT line, not so much in the Persona line (where you're lucky to get better than twenty points back).
- Of course, while it's something of a Useless Useful Spell for the player in the Persona series, enemies using said ability are even further into Demonic Spiders territory than quite a few enemies already are due to the difficulty of replenishing SP, particularly in Persona 4.
- A more useful variant is in Devil Survivor, that may even be considered a Game Breaker; it gets both HP and MP, is unblockable, and is nearly the only way to restore MP mid-battle.
- The Absorb Magicka spell from The Elder Scrolls series works like this, though it's usually useless, considering that it generally replenishes the magicka that you just used casting it. But if you forwent Destruction in favor of Mysticism/Restoration, then you don't have access to Drain/Damage Magicka.
- Defense of the Ancients: All-Stars Lion has a channeling mana drain. His counterpart from Heroes of Newerth, Witch Slayer, shares the same ability.
- EVE Online has energy vampires (usually called nos, or nosferatu after some of the different types available) that transfer some of the target ship's capacitor energy to your own. Something of a game breaker before being patched to not drain the target's capacitor to a lower percentage than your own. Some ships have bonuses to the drain amount of nos and neuts, the related mana burners.
- MapleStory has a passive version of this, called MP Eater, for wizards of all classes that has a percentage chance to drain a percentage of a target's mana for every magic attack. Because of the way it triggers, it's useless for actually gaining mana and mostly serves to lighten the cost of mana potions.
- Dark Heart Of Uukrul had the Sator and Rotas spells for this purpose. (One created a link, the other drew mana through it.)
- The ELS sucks EN in Super Robot Wars UX with their attacks, and if their victim runs out of EN, their mecha blows up. Ironically, the Mana-dependant Demonbane is immune to this, so Demonbane would be a perfect front-line fighter against the ELS.
- Descent II has Energy Bandits, which as their name suggests, drain your weapon energy.
- Lord Tirek in My Little Pony: Friendship Is Magic, a revamp of the classic Tirek from the G1 cartoon, has the power to drain magic out of ponies to increase his own power. He can even drain the flight and weather manipulation out of pegasi and the strength and Green Thumb abilities out of earth ponies. And once he becomes sufficiently powerful, he is even capable of draining the Chaos Magic power from Discord. This even carries over to Power Copying, as he seems to use Shining Armor's barrier spells when fighting Twilight Sparkle.
- In Trollz, this happened in the backstory. Simon grabbed a lot of the magic and turned it evil, taking it from male trolls and minimizing it for girl trolls. His abilities in the present day include magic-draining as well.
- In Barbie and the Secret Door, Malucia's magic wand drains others' magic.
