*** On a side note, Kyogre and Groudon have the ability to cause Rain and Sun, respectively, simply by being on the field until overwritten by another move. Rayquaza and Golduck[[AntiMagic nullifiy]] field effects simply by existing on the field.

* In FullmetalAlchemist (manga and second anime), alchemy takes its power from geothermal energy. The BigBad, Father, can block this energy, rendering alchemy useless in a given area. It does not block the similar magic of alkahestry, however, which has a different power source.

* In ''AvatarTheLastAirbender'', Firebenders and Waterbenders gain strength from the sun and the moon, respectively. Firebending is stronger during the day, and Waterbending is strongest on the night of a full moon.

** Fire Lord Sozin also decided to [[spoiler: make his ''own'' FieldPowerEffect with a "comet" that drastically powers up Firebending]]. He used it to [[spoiler: wipe out the Air Nomads, [[NiceJobBreakingItHerod 'cept for the one they were looking for]]]], and 100 years later, his descendant, Ozai [[spoiler: [[CompleteMonster tried to burn the whole ''Earth Kingdom'' at the comet's return]]]].

* ''YuGiOh'' has several dozen spells that give and remove field power bonuses and penalties. In the Duelist Kingdom arc of the manga, monsters get a 20% Field Power Bonus (actual name) to attack and defence in their preferred terrain - so bugs get it in forests, undead in wasteland, etc.

* Happens in ''DigimonAdventure'', when Etemon uses his Dark Network to depower the main 'mons.

* In ''AvatarTheLastAirbender'', Firebenders and Waterbenders gain strength from the sun and the moon, respectively. Firebending is stronger during the day. Waterbending strongest at the night of a full moon.

** The series bible also states earthbenders gain power from fault lines, and airbenders from higher altitudes. Neither is elaborated upon in-show. Other effects,like rain, is self explanatory[[http://www.racebending.com/v3/wp-content/uploads/2009/10/ipbible.pdf]]

* ''{{Pokemon}}'' has Weather Effects that benefit specific types, moves and abilities. It can be on Routes starting from Gen. 3, or you can set it up with respective moves or abilities.

In RealLife combatants naturally seek the high ground and other places on the battlefield with tactically advantageous GeoEffects, and to [[DefensiveFeintTrap maneuver their opponents]] into tactically disadvantageous positions. A related tactic is to affect allied and enemy morale to make the fighting easier. In fiction the Field Power Effect is a third, supernatural way to make a given set of characters (whether heroes or villains) stronger or weaker.

The reason Field Power Effects work is they somehow affect the PowerSource of characters, or failing that their {{Soul}}. An area filled with Light energy naturally strengthens characters who [[LightIsGood are good aligned]], while evil characters who are WeakenedByTheLight [[GoodHurtsEvil will suffer]] a {{De Power}}ing. It'd take a ''very'' strong CrossMeltingAura on the part of a villain to overpower that kind of disadvantage. The reverse is also true, an evil wizard who emanates [[TheDarkSide Dark Side]] energy will make heroes quake and those AllergicToEvil outright faint. In both cases the character will [[ImHavingSoulPains feel soul pains]].

!!Examples:

[[AC:{{Anime}} and {{Manga}}]]

* Used in ''InuYasha,'' occasionally. From dusk to dawn, on the first night of the new moon, Inuyasha turns human, returning to full power at sunrise.

* Some of the players in ''Manga/{{Saki}}'' are like that. Koromo draws strength from the night and the moon, so she's at her absolute strongest when the finals take place during a full-moon night. Yuuki is strongest during the East Wind, referring to herself as 'The Thunder of The East', while Nanpo Kazue is strongest during the South Wind. (A battle between Yuuki and Kazue has her hang on by a thread during the East Wind, and then make a huge comeback during the South Wind, winning the game by a large margin.) Initially, Nodoka also had a FieldPowerBonus when playing Online, losing significant power when playing in person, but she eventually gained the ability to go into full 'Online Mode' in a live game, though it usually takes her a while...

[[AC:TabletopGames]]

*** A spell called Consumptive Field that drains hit-points from all characters in a area, potentially lethally, transferring them to the caster.
* ''{{Exalted}}'' has several examples related to the Exalt type.
* The spells "Hallow" and "Unhallow" from ''DungeonsAndDragons'' cause an area to favor good-aligned or evil-aligned characters respectively.
* ''MagicTheGathering'' has dozens of such spells for specific colors and creature types.

[[AC:VideoGames]]

* In ''BattleForWesnoth,'' lawful units fight better at day, and chaotic units fight better at night (and both fight worse at the opposite daytime). As well, the Mage of Light unit can illuminate an area with their presence, being a FieldPowerBonus for lawful and a FieldPowerDrain for chaotic units at the same time.

* One of ''VideoGame/ExitFate's'' Demon Commandos possesses a spell permanently buffing up his own party, and the other one has a spell {{Field Power Drain}}ing the enemy party.

* ''{{Pokemon}}'' has Weather Effects that benefit specific types, moves and abilities. It can be on Routes starting from Gen. 3, or you can set it up with respective moves or abilities.
** Rain boosts [[MakingASplash Water moves]], weakens [[PlayingWithFire Fire moves]] and makes Thunder and Hurricane 100% accurate.

* The Disney ''{{Gargoyles}}'' sleep during the day, and awake at sunset. A somewhat extreme example, since they're helpless from sunrise to sunset.

* ''ChronoCross'' has a field effect that, when biased completely to one colour, empowers spells of the same element and weakens those of the opposite and makes SummonMagic of that element useable. Good luck doing this when enemies are using their own spells. One character has a special ability where he changes the field colors to all one color (he spills paint), but you can't choose the color. There are also normal spells that can change the field to a single color except black and white.

* In ''VisualNovel/FateStayNight'', both Caster and Rider seem to use such effects to absorb energy, although we only see the effects on the field created by Rider, when it drains life power from the students of the school. Also, Ryuudou temple seems to fulfill a similar role, as it weakens all the servants who go into it, ([[GameplayAndStorySegregation or so we are told)]].
** [[RealityWarper Reality marbles]] also do this, imposing the user's {{mental world}} on their surroundings.

* On ''[[FateStayNight Fate/Stay Night]]'' both Caster and Rider seem to use this, using them to absorb energy and become more powerful, although we only see the effects on the field created by rider, were it drains almost all the vital energy of all the muggles in the School. Also the Ryoudouji temple seems to fulfill a similar role, as it weakens all the servants who go into it, ([[GameplayAndStorySegregation or so we are told)]].
** [[RealityWarper Reality marbles]] also do this, imposing the user's [[MentalWorld mental world]] on their surroundings.
