History Main / ReducedManaCost

* The "Pressure" ability from the ''{{Pokemon}}'' series is an inversion of sorts - the ability doubles the PP consumption for any Pokemon engaged against the ability's user. Irritatingly, it's on too many Legendaries to keep track of, the few known exceptions including, but not limited to, the Weather Trio (Groudon, Kyogre, Rayquaza) and the Isshu Pair (Reshiram and Zekrom do not have it).

* In HeroesOfMightAndMagic 5 heroes can learn a skill "Arcane Training" to permanently cut the mana cost of all his spells by 20% and then another one, "Erratic Mana", to randomly cut the cost of each cast cast by up to 50% more.

* ''TalesOfVesperia'' has rings that reduce TP costs by amounts similar to the Phantasia example, but also has a notable GameBreaker in the form of the Risky Ring, which reduces TP costs to 1 at the minimal cost of significantly reduced defenses. Defense isn't an issue when artes can be spammed constantly, thus preventing oneself from getting hit in the first place, though.

* The ''FinalFantasy'' games love these. Every game after III has an accessory that halves MP cost, usually called the "Gold Hairpin". In ''VideoGame/FinalFantasyVI, there's an accessory that reduces it to ''one'' (and, once you have Ultima, it becomes ridiculously {{game break|er}}ing). ''VideoGame/FinalFantasyX'' also does this.

* ''Shin Megami Tensei DevilSurvivor'' has a skill called Magical Yang that halves MP costs for both the user's party and the enemy party they're currently fighting against, and inverts it with Magical Yin that makes the spells cost double the MP but giving them a 50% power boost. Despite the lack of any MP-restoring items, the latter is a far better option most of the time thanks to the ManaDrain spell's effectiveness in both crippling the enemies and giving their MP to you and because of a racial skill that restores a set amount of MP to all your characters after combat depending on how much damage you do to your enemies.

In FinalFantasyVI, there's an accessory that reduces it to ''one'' (and, once you have Ultima, it becomes ridiculously [[GameBreaker game breaking]]). FinalFantasyX also does this.
** ''Final Fantasy X-2'' has the Soul of Thamasa, which doubles the cost of spells and increases the damage they inflict, and the Ragnarok, which makes any skill or spell cost 0MP. They are practically a GameBreaker when equipped on the same character.
** Final Fantasy VII Crisis Core has many items that do this like the SOul of Thamasa which reduces all MP costs to 0. The Genji helm also does this and while it is useful, it is not as useful sometimes as say the Ziedrich, an item that increases all stats by 100.
* ''FinalFantasyVIII'' and ''FinalFantasyXIII'', lacking traditional MP, has other ways to accomplish this. ''VIII'' has the "Expend2x1" and "Expend3x1" that allow you to cast two or three times at the expense of one spell stock. ''XIII'' has various weapon modifications that charge your ATB rate, effectively allowing you to cast faster.
* While ''FinalFantasyXI'' lacks a straight example of this trope, as everyone would be required to have one and therefore no one could afford one, some pieces of mage gear have a degree of the Conserve MP trait, which confers a small chance of halving the MP spent on a spell.

* ''TalesOfPhantasia'' has three types of rings that reduce TP cost by 1/3, 1/2, and 2/3.
* ''ChronoTrigger'' has not only the Silver Stud, which cuts MP cost by half, but the Gold Stud, which cuts it to 25%. The latter is a serious GameBreaker thanks to the Black Omen, from which you can farm enough to supply your entire roster.
** Advanced magic in ChronoTrigger is incredibly powerful but balanced by its extremely high MP cost, making Golden Studs a complete GameBreaker. Luminare won't outright kill most enemies, but two uses will, and three uses will make ''bosses'' cringe.

* Conserve Power from CityOfHeroes.

* [[JaysJourney Jay's Journey]] has the Gold Hairpin. Like in Final Fantasy, (which it's probably a ShoutOut to) it halves MP cost.
* The second and third ''{{Disgaea}}'' games play this straight and invert it. The all-female Mage class can cast spells with less SP than any other character in the game, while the all-male Skulls require 50% more SP to use their spells, but they hit harder. Then again, considering how ridiculous the stats can get, it's pretty much impossible to run out of SP in the endgame, no matter how many level 100 spells and skills you spam.

* Numerous examples exist in ''[=~Magic: The Gathering~=]'', ranging from completely useless to potentially gamebreaking.
* Inverted in ''World of Warcraft'', the curse of Lucifron makes every ability cost double its initial cost, and even works on the Death Knight class which uses "Runes", which wasn't invented when Lucifron was made.

* Shin Megami Tensei DevilSurvivor has a skill called Magical Yang that halves MP costs for both the user's party and the enemy party they're currently fighting against, and inverts it with Magical Yin that makes the spells cost double the MP but giving them a 50% power boost. Despite the lack of any MP-restoring items, the latter is a far better option most of the time thanks to the ManaDrain spell's effectiveness in both crippling the enemies and giving their MP to you and because of a racial skill that restores a set amount of MP to all your characters after combat depending on how much damage you do to your enemies.

* ''KingdomOfLoathing'' has a few of these, including a recurring in-game holiday. Most of them will only stack to -3 MP per casting. A few do ignore that limit, including the aforementioned holiday, so you could theoretically get a reduction of 9 MP off every skill you cast, or 14 if you're a Pastamancer. This would be a GameBreaker if the most useful non-combat skills weren't also limited to a certain number of uses per day.
* A [[DungeonsAndDragons Psionic]] in 3rd edition could purchase a Torc of Power Preservation to get this effect. While the actual amount of PP (mana) preserved was only 1 point, it could easily extend your pool of mana immensely (as you can manifest numerous powers each day in the mid-to-high levels). There are feats and prestige classes that have similar effects (major examples include the Anarchic Initiate [[PrestigeClass PrC]] and the Midnight Augmentation feat). And the Wilder base class has one of these built in (but it has... issues).

* The equivalent in ''DungeonsAndDragons'' third edition, a few [[TookALevelInBadass prestige classes]] reduce or nullify the cost of "metamagic", i.e. a way to make your spells stronger. The effect is that you can make all your spells stronger at no added cost; this is very much a GameBreaker.
* In {{Terraria}}, wearing the entire set of Jungle Armor will reduce the mana cost of all magic items by 16%. This stacks with the Nature's Gift accessory, which reduces mana costs by 6%.

* The Lord-Sorcerer's Gown in ''LastScenario''. Also inverted with the Spellcard Mod, which doubles MP cost but multiplies damage by 1.5.

* ''DeusEx'' has the Power Recirculator, which reduces augmentation energy use by 10%-60% for a piddling 10 units/minute.

* Lots of items in MarioAndLuigiBowsersInsideStory: The Budget Charm, the Thrift Charm, the Tight Belt, the Economy Ring and the Cheap Ring. Inverted with the Luxury Patch and Heroic Patch, which raise SP cost in return for added power for the attacks as does the Heroic Ring. Some even auto restore the amount once per turn.

* ''SuperMarioRPG'' has an accessory that cuts Flower Point costs in half.

** Actually This troper must correct the above posting - normally, Double and Triple cast the same spell for the cost of 2 or 3 respectively, and only the GF abilities Expend2x1 and Expend 3x1 allow the aforementioned "Two for One" and "Three for One" in Final Fantasy VIII.
