If something proves effective in RealLife combat, it would be wise to [[SpamAttack do it again as quickly as possible]].

Most game characters don't have that option, however, and will be forced to wait for a fixed period of time or a certain number of turns before they can use that room-clearing move again. While it could be argued that said move was exhausting and that the character needed to recover before acting again, why is he or she able to use a different and more powerful move immediately? More importantly, why does ''that'' move have its own fixed recovery time, completely independent of the other one? Why does the ''majority of the character's repertoire'' have such recovery times?

The use of MagicAIsMagicA can HandWave this requirement but credibility is stretched for purely physical fighters. It's believable that a warrior would need to rest for five seconds after slashing six times in a row with a {{BFS}}, but it's less believable that the move's five or seven-hit cousins can be used immediately during those five seconds. The result is that moves become like on-board weapons with differing reload or recharge intervals.

The gameplay reason is to prevent players from [[ComplacentGamingSyndrome repeating a super move over and over again]] until they run out of {{Mana}}, while still allowing them to defend themselves with other moves. If nothing else, it forces gameplay to become somewhat more 'varied' in that players can at best repeat a '''sequence''' of moves instead of using a '''single''' move ad nauseum.

This frequently overlaps with RegeneratingMana.

The [[TropesAreNotBad upside]] to this mechanic is that it adds a layer of complexity to the overall {{Metagame}} as players have to deal with timing as well as damage numbers and StandardStatusEffects. Changing a skill's recovery time has a disproportionately large effect on its usefulness compared to its other statistics as one second less can make it a {{Gamebreaker}} while one second more can make it entirely useless. As a result, the recovery time of an ability is almost always balanced against that of others as opposed to approximating reality or following flavor. Sometimes, [[CooldownManipulation cooldowns can be manipulated in certain ways]], to add more to the complexity.

Certain games also have a '''global cooldown''', which triggers after ''any'' sequence of moves depletes a character's 'stamina' or 'energy' and disables ''all'' moves while it recharges, possibly closer to how this mechanic would work in RealLife--see CombatantCooldownSystem for that. There are also games with a combination of both, such as having common cooldowns for different sets of moves rather than all moves or having some moves with individual cooldowns and others shared.

Compare TheLawOfPowerProportionateToEffort. Not to be confused with {{Overheating}}, which is about firearms that cannot fire non-stop, even with BottomlessMagazines.



[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** The Fourth Edition provides a {{tabletop RPG}} example with its split of at-will, encounter (basically "usable once per fight") and daily powers for virtually all classes. At-will attack powers in particular were sharply limited in number -- most characters would start with two, perhaps three different class-specific at-will moves at their disposal right at level 1 and then never get any more or improve them much, forcing them to increasingly rely on their daily and encounter powers as those became available.
** The ''Tome of Battle'' supplement for edition 3.5 has a variant -- each of a character's martial maneuvers can be used once per combat, but they can pause to "refresh" them so that they can be used again. The [[SupernaturalMartialArts swordsage]], who relies on rote memorization, knows a large number of maneuvers but must spend his entire turn to refresh even one. The [[GeniusBruiser warblade]], who relies on improvisation and practical experience, knows a moderate number of maneuvers but can refresh all of them at once by making a basic (non-maneuver) attack. The [[{{Determinator}} crusader]], who relies on instinct and tenacity over skill, knows a small number of maneuvers and [[FightLikeACardPlayer the selection he can use at any one time is randomized]], but they refresh automatically (i.e. he never runs out).
* In ''TabletopGame/HcSvntDracones'' a character that is Masterful in a proficiency can automatically put one success on a roll of that skill per day, at Preeminent they can auto-pass a check regardless of how many successes it required, daily. While many Focus abilities are "once per session".

[[folder:Video Games]]
* ''VideoGame/DiabloII'' had the combination. Some spells were cooldown spells, some could be cast continuously. Unlike most games, if any cooldown spell was used, it would prevent all other cooldown skills from being used for the period, not just itself. Many skill setups in the game involved combining a cooldown skill with a fast casting skill.
* All special abilities and magical spells in ''VideoGame/DragonAgeOrigins'' have cooldown periods in addition to consuming stamina and mana, respectively. Even more credibility-stretching, healing potions and ''hand grenades'' also have cooldowns.
* ''VideoGame/CityOfHeroes'' has a recharge time for all powers.
* RTS games use this mechanic for [[WeaponOfMassDestruction superweapons]] and CO powers. In games where individual units or heroes have special powers, those tend to have cooldowns as well.
* ''VideoGame/TheWorldEndsWithYou''. All abilities can be used instantly a certain number of times before entering a cooldown period.
* All special abilities in ''VideoGame/AlphaProtocol'' have a cooldown time, which can be reduced by certain perks or armour upgrades. The ability Brilliance (which, itself, has a base cooldown time of 300 or 45 seconds) resets the timer for every other ability. [[ThatOneBoss Brayko]] becomes much less of a threat when you can use [[GameBreaker Master Chain Shot]] on him twice on a row.
* ''VideoGame/BloodlineChampions'' uses cooldowns to limit abilities, as well as having them all activate global cooldowns. Certain abilities can be used to refresh these cooldowns or cause the enemy to suddenly have their abilities to suddenly be on a temporary cooldown, and a few may be activated that ignores the global cooldown.
* ''VideoGame/TeamFortress2'' - The Scout's Bonk! Atomic Punch, Crit-a-Cola, and Mad Milk, the Demoman's Chargin' Targe and Splendid Screen charges, the Sniper's Jarate, and the Heavy's Sandvich and Buffalo Steak Sandvich are all subject to cooldown, though they can be recharged instantly by visiting the respawn lockers, the Sandvich can also be recharged by picking up a health pack when you already have full health and the Sandman's ball can be recharged by picking up the ball again if it missed the target.
* In ''Day of Defeat'' Axis machinegun is [=MG42=], which quickly heats up when fired, so the player has a choice between shooting very sparingly and having a period of vulnerability later when the barrel finally overheats.
* ''VideoGame/StarCraftII'' is moving a bit in this direction, where some {{Mana}}-based abilities are being replaced with cooldowns.
* All MultiplayerOnlineBattleArena have a cooldown mech. Some abilities are intended to be spammed and have, say, 5i-ish second cooldown, some may be used once in a fight and have a cooldown of 10-15 seconds, and ultimates are saved for big teamfights and thus have up to 2 minutes cooldown.
* ''VideoGame/WorldOfWarcraft'' uses cooldown management extensively for class balance. All classes have some form of resource management, whether it be mana, runic power, energy, rage, etc.; but also mix this up with cooldowns for individual abilities and occasionally shared families of abilities. To this, add a global cooldown, plus certain abilities that aren't on the global cooldown but ''also'' have their own shared cooldowns. The {{Metagame}} of managing one's cooldowns can therefore become as much if not more a part of the game mechanics as the abilities themselves. In some cases, the "rotation" that one goes through with their character can affect Damage Per Second or Threat per second by several THOUSAND points, but are typically obscure and can only be found out by people using add-ons, trial and error, or just being told what to do.
* ''VideoGame/LeagueOfLegends'' has a hero type whose resource management is replaced by cooldown management. To clarify: all characters in the game have cooldown on all of their abilities. Most champions also have a resource bar, meaning they can't spam abilities for two reasons (cooldown and mana cost, essentially). However, some champions, such as Garen and Katarina, don't have a resource bar, and instead can spam their abilities as long as they arent on cooldown.
* In a similar vein to the MOBA examples above, ''VideoGame/DirtyBomb'' restricts the Mercs' Abilities with cooldowns. No other restriction on any Ability exists, meaning [[LightningBruiser Proxy]] has infinite landmines or [[SkillGateCharacter Skyhammer]] can resupply everyone ad nauseam. Some Abilities, however, can have uses "stacked": a maximum number of the Ability is stored and can be used at will, but waiting for the cooldown only restores one use.
* The ''Franchise/MassEffect'' series has both versions with various tradeoffs.
** In ''VideoGame/MassEffect1'', each power has its own cooldown, which is abominably long or somewhat fast, depending on what passive abilities you have equipped.
** In ''VideoGame/MassEffect2'', however, using one power put all the other powers on a cooldown after using only one power. In exchange, though, the cooldowns are greatly reduced to a few seconds for almost every ability; powers with cooldowns longer than ten seconds are almost non-existent. Unless the squad members use their powers, since the squad members have much longer cooldown times than Shepard.
** ''VideoGame/MassEffect3'' removes cooldowns from ammo powers and introduces powers that run on a limited stock of grenades rather than cooldowns (or in the case of Nova and Phase Disruptor, the user's barrier). Armor powers no longer trigger cooldowns on activation, but do trigger a cooldown when "detonated" and impose a cooldown penalty when active.
** In the case of biotic powers, this is somewhat explained away in the ExpandedUniverse. Biotic powers are difficult, and heavy use of them will very quickly wear out a biotic, meaning they can actually only use them sparingly. This means the game's portrayal is a bit of an inversion, as in-game biotics cool down a whole lot faster than "real" biotics would!
* ''VideoGame/HyperdimensionNeptunia'' suffers from this when you're not in battle. In the dungeons, it is possible to execute one of three actions; swing a hammer overhead to clear away a breakable wall in front of you (as Neptune), ring a bell to trigger battles (as Compa) and show the location of the dungeon's hidden treasure chest (as IF). Problem is, the cooldown times for these abilities are atrociously long. It takes around half a minute for Neptune to swing the hammer again, which is kind of fair enough when you consider it's very heavy, but Compa has to wait about fifteen seconds to ''ring the bell once more''.
* ''VideoGame/EveOnline'' has the global session change timer, which starts when you do an action on a rather small list and forces you to wait 30 seconds before doing another (these include actions like dock at a station, change the ship you're in, join/leave a fleet, use a stargate, ''log on to the game''; you know, that sort of thing). Most active modules have individual cooldown as well; active, repeating modules call it ''cycle time'', while non-repeating modules call it a ''reactivation delay''.
* ''VideoGame/{{Solatorobo}}'' has cooldown present only in the fishing minigame; any weapons can be fired until they run out of ammo.
* In ''VideoGame/AlienHallway'', the cooldown time is represented by a shaded-out area over the icon, which gradually drains away. When a unit is available again, its icon lights up green.
* Most active abilities in ''VideoGame/XCOMEnemyUnknown'' have cooldown timers. Standard is two turns, while the most powerful abilities can take up to five.
* In ''VideoGame/TheElderScrollsVSkyrim'', [[MakeMeWannaShout Shouts]] have a global cooldown period related to how powerful they are and what level is used (One, two or three words).
* Certain moves in ''Franchise/{{Pokemon}}'' force the user to recharge for a turn after use due to the amount of energy they expend, including [[WaveMotionGun Hyper Beam]], [[TimeCrash Roar of Time]], and the special starter-only attacks.
* Many Gifts in ''TabletopGame/{{Ironclaw}}'' and ''TabletopGame/MyriadSong'', particularly spells and Xenharmonic powers respectively, recharge after spending a battle action or following a "respite", some of the more powerful ones are only once a game-chapter or have special conditions.
* In ''VideoGame/RadiaSenkiReimeihen'', party members have a Power meter that has to refill before they can use another Tech. The Power meter is inversely proportional to the character's HP meter, meaning characters with higher HP have shorter cooldowns.
* Special moves in ''VideoGame/RisingThunder'' are activated by single buttons instead of more complicated inputs, but all have cooldown timers to limit their use. Some things override the timer to end cooldown immediately, including Chel's [[EnergyBall Night Sun]] hitting or being blocked.
* ''VideoGame/{{Ingress}}'' lets you hack a Portal once every five minutes, with the explanation of "Portal running too hot!" if you try to hack it again too early. There's also Portal burnout, which kicks in after you've hacked a Portal four times and requires you to wait four hours to hack it again. Installing a Heat Sink mod on a Portal cuts down the cooldown period between hacks, while installing a Multi-Hack mod increases the number of times you can hack a Portal before it burns out.
* In ''VideoGame/MonsterHunter'', the Gunlance's [[LimitBreak Wyvern Fire]], various maps' [[ImpaledWithExtremePrejudice Dragonators]], the Restraints and [[FixedForwardFacingWeapon Demolisher]] in the Battlequarters, various ships' Ballista Binders and Hunting Gongs, the Frenzy-suppressing Wystones, among many, many other things have cooldown periods on the order of minutes. Using one of these ineffectively can be very costly in a quest.
* ''VideoGame/XenobladeChroniclesX'' expands on this mechanic with "secondary cooldowns" -- if you choose not to use an Art as soon as it's available and have the corresponding weapon drawn, a second gauge fills up, which depending on the Art will power it up or allow it to be used again immediately. Entering [[LimitBreak Overdrive]] massively shortens the wait times and also enables ''tertiary'' cooldowns.
* In ''VideoGame/NocturneRPGMaker'', all physical skills and stronger spells require a certain amount of turns to cool down. Physical skills have a longer cooldown time, but usually cost little to no MP to compensate. However, the Accelerate passive gives a chance of instantly refreshing a non-ultimate skill.
* In ''VideoGame/{{Miitopia}}'', the Ancient Robots and their boss equivalents are forced into this state for a few turns after firing their powerful FrickinLaserBeams. During cooldown, they can only perform ramming attacks, but they gain an ExtraTurn.
* ''VideoGame/FTLFasterThanLight''
** Each FTL engine takes time to charge up and requires someone in the cockpit to do so. Putting more power into the engines decreases the delay.
** All weapons come with a delay from few to 20 or so seconds before they can fire. This delay can be shortened by posting someone to a weapons system or with augmenations.
** Teleporters, cloaking, mind control, hacking and back-up battery all become ionized once their effect wears off (or in case of teleporters, the moment someone gets teleported), rendering them unusable for some time.
** A certain race comes with an ability to lock whatever room they are in for some time, but it can be used only sparingly due to a cooldown period.
