History Main / AttackFailureChance

* ''VideoGame/{{Pokemon}}'':

* ''VideoGame/JaggedAlliance2'': Guns [[BreakableWeapons degrade]] and will jam or misfire when degraded, but only for the player.

* ''TabletopGame/ArsMagica'': As with all actions, spellcasting under stressful circumstances has a 1-10% chance of a CriticalFailure, depending on aggravating and mitigating factors. The effects are open to the GameMaster's interpretation based on how badly the dice roll was botched, but the spell might go off-target, have the opposite of its intended effect, invite DemonicPossession, or complicate the magus's day in some other exciting manner.

* ''VideoGame/{{Diablo 1}}'', which was based on {{Roguelike}}s, based both melee and ranged hit chances on your Dexterity, and if it was low enough, you could forget about hitting anything with your sword or bow. Thankfully, the Dexterity issue was easy enough to fix with enough Level Ups, particularly since Dexterity also governed block chance and ranged damage.

* The early ''VideoGame/{{Diablo}}'' games, which were based on {{Roguelike}}s, based both melee and ranged hit chances on your Dexterity, and if it was low enough, you could forget about hitting anything with your sword or bow. Thankfully, the Dexterity issue was easy enough to fix with enough Level Ups, particularly since Dexterity also governed block chance and ranged damage.

** ''Rewritten'' allows Toon-Up to miss, unlike in ''VideoGame/ToontownCorporateClash''. If the Toons give lowercase chuckles, it missed, but if there's at least one capital letter in the laugh, it landed.

* ''VideoGame/TheElderScrolls'':

** In ''VideoGame/ToontownCorporateClash'', Zap will miss entirely on unsoaked cogs. You need to attack a cog with Squirt, which soaks adjacent cogs as well.
** In ''VideoGame/ToontownCorporateClash'', Toon-Up has perfect accuracy, where it can miss in ''Rewritten''. If the Toons give lowercase chuckles, it missed, but if there's at least one capital letter in the laugh, it landed.

* [[EarlyInstallmentWeirdness In its very early years]], ''VideoGame/LeagueOfLegends'' had a universal stat known as "Dodge", implemented as a sort of inverse to "CriticalHit Chance" that allowed certain characters to randomly [[NoSell shrug off basic attacks to receive no damage]]. Only one champion had innate Dodge as part of their kit -- Jax, whose ability "[[CounterAttack Counter Strike" granted him Dodge over several seconds before retaliating based on whatever damage he absorbed -- for everyone else, it was only granted in single-digit amounts from various [[SupportPower Runes and Summoner Masteries]] as well as from the item "Ninja Tabi" (a set of boots that granted a 12% Dodge chance). There also existed the "Sword of the Divine" item [[TacticalRockPaperScissors designed to counter the stat]], having an active buff [[AlwaysAccurateAttack to completely bypass Dodge and deal full damage all the way]]. Dodge was eventually removed from the game in 2012 as it wasn't fun on either end of the exchange (frustrating attackers to lose damage at random, unsatisfying and unreliable for targets), with Jax's "Counter Strike", Ninja Tabi, and Sword of the Divine all being majorly reworked (the latter item removed altogether by late 2014).

** Certain [=SOS=] Cards can guarantee that Toons will guarantee their attacks land every turn. There are also attacks that guarantee the Cogs' attacks will ''miss'' every turn. [[note]]An update to Toontown Rewritten nerfed this, so this instead modifies the accuracy instead. Corporate Clash removes SOS Cards entirely, replacing them with I.O.U.s that instead boost the damage of certain gag tracks. [[/note]] The star rating of the SOS card will determine how many rounds this will last.

** In Toontown Corporate Clash, Zap will miss entirely on unsoaked cogs. You need to attack a cog with Squirt, which soaks adjacent cogs as well.
** In Toontown Corporate Clash, Toon-Up has perfect accuracy, where it can miss in Rewritten. If the Toons give lowercase chuckles, it missed, but if there's at least one capital letter in the laugh, it landed.

The simplest RolePlayingGame combat systems have every attack be an AlwaysAccurateAttack. But this trope is for when there's ''quantified'', usually-percentage, chances for attacks to fail somehow: misses, gun jams, {{Magic Misfire}}s, SelfDamagingAttackBackfire, and similar. Missing attacks might also be caused by a StatusEffect, usually called "Blind".

* With guns, or ARMs being one of the most notable weapons in the ''VideoGame/WildArms'' games, accuracy is a bit of an issue. If an ARM has low accuracy, then there's a higher chance its attacks will miss. (The most notorious for this is Rudy's Wild Bunch ARM in the original game.) Upgrading ARMs can mitigate this, as can the Lock-On force (if a character has it).
** In some games, ARMs can malfunction. This can happen to Jude in the fourth game, as well as to Rudy in the remake of the first game.

* ''TabletopGame/ChroniclesOfDarkness:'' To attack you roll a number of [=d10s=] equal to Strength + Brawl - the opponent's Defense (if it's an unarmed attack), Strength + Weaponry - the opponent's Defense (if it's a melee attack with a weapon), Dexterity + Athletics - the opponent's Defense (for thrown weapons) or Dexterity + Firearms (for ranged weapons like guns and bows)[[note]]You don't subtract Defense from your roll in this case because normally one can't dodge bullets. Some powers such as [[TabletopGame/MageTheAwakening Fate, Space or Time Mage Armor]] let you dodge bullets and thus subtract your Defense from ranged attacks performed against you, or, in the case of [[/TabletopGame/VampireTheRequiem the Celerity Discipline]], subtract dice from the attack pool to represent supernatural speed[[/note]]. This represents, for the most part, the attack's chance to miss -- partially or completely {{No Sell}}ing an attack is represented by Armor (which, once an attack hits, reduces the amount of damage you take).

And since AlwaysAccurateAttack is for when ''specific'' attacks are like that, it means that all games listed there, would go here too, since this is the inversion, when attacks can miss, and there's no point in calling out specific attacks, if they're ''all'' like that.

CriticalFailure will overlap a lot because a random chance of horrible failure for possibly anything, likely includes attacks in that ''anything''. A BreakableWeapons system that includes multi-part weapons like guns or bows, may include a chance for gun jams or string snaps, etc, at high damage levels.

** It powers ''TabletopGame/BlackbirdsRPG'': Attempting to cast a Vitiation or a Spell requires an skill test, and critically or sublimely failing this test can cause some horrible effect to the target or the caster, depending on the spell. For example, attempting to magically empower a nearby weapon will instead destroy it on a CriticalFailure, or destroy ''all'' nearby equipment on a sublime failure.

* ''VideoGame/DarkestDungeon'': The percentage for an attack to land is determined by a character's Accuracy versus an enemy's Dodge chance, which can be increased or decreased by a variety of buffs, debuffs and equipment throughout the game. Normally an attack has about a 90 or 95 percent chance to hit, but if that chance is higher or lower due to influencing factors then it will be displayed instead.

*** While this is a game where weapon targeting is controlled in real time, quantified skill in the appropriate weapon type controls whether the equipped weapon hits on not, since the series was still in transition from its FauxFirstPerson3D roots.

* ''Franchise/FireEmblem'': Devil weapons, like the Devil Axe and Devil Sword, have a chance of SelfDamagingAttackBackfire. In ''VideoGame/FireEmblemGaiden'', there is only the Shadow Sword, since axes doesn't exist in the player's hand, which has a similar effect to the Devil Axe, but Dread Fighters are immune to it. In most games, the backfire rate is decreased by the unit's Luck stat, but, in ''VideoGame/FireEmblemTheBindingBlade'', it is decreased by the unit's displayed Level instead. Regardless of the reduction, Devil weapons will always have at least 1% to backfire. [[CriticalFailure Hope you don't get a critical hit when the Devil Axe backfires]]. Since ''VideoGame/FireEmblemFates'', Devil weapons decreases your [[CastFromHitPoints HP]] when you attack with it.

* The UsefulNotes/ExidySorcerer game ''VideoGame/WizardsCastle'': An attack hits if the player's dexterity value is greater than a randomly generated number from 1 to 21, or 4 to 25 if they're blinded. Dexterity can can be from 1 to 18, with [[StatDeath zero dexterity equalling death]].
* ''VideoGame/XCOM2'' has a mechanic known as Dodge that applies to several enemies, as well as XCOM soldiers with the right gear. Dodge is a percent chance that isn't shown to the player, takes priority over critical hits, and enemies that Dodge take partial damage from the attack with the message "Dodge-Grazed" appearing when the damage pops up. The 1.0 version of the game allowed this to happen even on shots that had a 100% chance to be hit.

* ''Franchise/FireEmblem'': Devil weapons, like the Devil Axe and Devil Sword, have a chance of SelfDamagingAttackBackfire. In ''VideoGame/FireEmblemGaiden'', there is only the Shadow Sword, since axes doesn't exist in the player's hand, which has a similar effect to the Devil Axe, but Dread Fighters are immune to it. In most games, the backfire rate is decreased by the unit's Luck stat, but, in ''VideoGame/FireEmblemTheBindingBlade'', it is decreased by the unit's displayed Level instead. Regardless of the reduction, Devil weapons will always have at least 1% to backfire. [[CriticalFailure Hope you don't get a critical hit when the Devil Axe backfires]]. Since ''VideoGame/FireEmblemFates'', Devil weapons decreases your [[CastFromHitpoints HP]] when you attack with it.

* ''VideoGame/{{Pokemon}}'': Some moves don't have accuracy of 100% or greater, and if an attacker had their accuracy lowered or the defender had their evasion increased, that can make what was labeled as 100% accurate attacks, miss instead. ''VideoGame/PokemonRedAndBlue'' has the 1/256 accuracy glitch that gives ''all'' attacks that possess an accuracy stat, that specified chance to miss.

* The early VideoGame/{{Diablo}} games, which were based on {{Roguelike}}s, based both melee and ranged hit chances on your Dexterity, and if it was low enough, you could forget about hitting anything with your sword or bow. Thankfully, the Dexterity issue was easy enough to fix with enough Level Ups, particularly since Dexterity also governed block chance and ranged damage.
