History Main / ManaDrain

*** Similarly, ''StarWars: Knights of the Old Republic 2'' 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.

* This was one of the ways you filled your ManaMeter in ''SilhouetteMirage'', 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.

* The game itself performs a "Mana Drain" on both you and your opponent in ''Puzzle Quest: Challenge of the Warlords'' 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 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 WorldOfWarcraft, 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.

* "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.

* Mana Drain from ''ShinMegamiTenseiNocturne.''

* The ''ShinMegamiTensei'' 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).

* Some of the ''DragonQuest'' games have enemies doing a "strange dance" which lowers one's mana. This was [[ShoutOut referenced]] in the baseball episode of ''SuzumiyaHaruhi'' ("Is Haruhi trying to lower the pitcher's MP?").
** A couple of heroes can perform this dance as well. Taloon from [[DragonQuestIV DQIV]], for example, does this at random times.

** A more useful variant is in ''DevilSurvivor'', that may even be considered a [[GameBreaker Game Breaker]]; it gets both [[LifeDrain H]][[HitPoints P]] and [[ManaDrain M]][[ManaPoints P]], is [[NonElemental unblockable]], and is nearly the ''only'' way to restore MP mid-battle.

* In WorldOfWarcraft, shadow priests have this ability.
** One boss in Icecrown Citadel -- Lady Deathwhisper -- 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.

* ''LordOfTheRingsOnline'' 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.

** Yamachika's zanpakuto could drain his enemy's reiatsu, essentially [[OneHitKill instant win]]

** A more useful variant is in ''DevilSurvivor'', that may even be considered a [[GameBreaker Game Breaker]]; it gets both [[LifeDrain H]][[HitPoints P]] and [[ManaDrain M]][[ManaPoints P]], is [[NonElemental unblockable]], and there are no restore items to be found.

When this is done to HitPoints it is LifeDrain.

* ''DefenseoftheAncients'' Lion has a channeling mana drain. His counterpart from ''HeroesofNewerth'', Witch Slayer, shares the same ability.

* Many characters in ''DragonBallZ'' can absorb Ki from attacks. An android once suckered someone into using an extremely powerful attack to obliterate their hiding place, only to zip out and slurp it up through his hands before it hit.
** This is played with later in the Buu story arc. Goku fights a creature on Babidi's ship that drains his power whenever he turns Super Saiyan. [[spoiler: He destroys it by turning Super Saiyan 2 for a very brief moment; the sudden influx of energy is too much for the creatures body and destroys it]].

* The Blood Mage in ''{{Warcraft}} III: The Frozen Throne'' has a ManaDrain ability called "Siphon Mana". This can also be used on allies, draining mana from the Blood Mage into the ally. Also, a unit with the "Feedback" ability (see ''{{Starcraft}}'', above) will "combust" its targets mana, dealing extra damage in the process. The Mana Burn spell lowers enemy mana and deals damage depending on the amount of mana lost.
** The warlock and the priest in ''WorldOfWarcraft'' both have mana draining/destroying abilities. The warlock can restore his own mana using his ability, and the priest can damage the target as well as drain their mana using her ability. The Blood Elf race has an inherent ability that also allows them to drain mana. Hunters also get the Viper Sting ability, which just does damage to the target's mana over time, and is in fact one of the ''least'' effective methods of denying spellcasters their energy.

* The ''ShinMegamiTensei'' series has Spirit Drain (since their version of mana is Spirit Points). 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 UselessUsefulSpell for the player in the ''Persona'' series, ''enemies'' using said ability are even further into DemonicSpiders territory than [[NintendoHard most enemies already are]] due to the difficulty of replenishing SP, particularly in ''{{Persona 4}}''.
** Even more useful during ''DevilSurvivor'', since it gets both HP and MP, is unblockable, and there are no restore items to be found.

** In ''FinalFantasyTacticsA2'', 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 to powerful for 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 '''H'''P. The Lanista attack "Sword of Light" still does this conventionally, probably because Seeq don't have a lot to spend MP on.

* The Blood Mage in ''{{Warcraft}} III: The Frozen Throne'' has a ManaDrain ability called "Siphon Mana". Also, a unit with the "Feedback" ability (see ''{{Starcraft}}'', above) will "combust" its targets mana, dealing extra damage in the process. The Mana Burn spell lowers enemy mana and deals damage depending on the amount of mana lost.

** Of course, while it's something of a UselessUsefulSpell for the player in the ''Persona'' series, ''enemies'' using said ability are even further into DemonicSpiders territory than [[NintendoHard most enemies already are]] due to the difficulty of replenishing SP, particularly in {{Persona 4}}.
