Accuracy

Accuracy Rating determines whether an Attack Hits by being compared with the target's Evasion. Player Attacks also lose Accuracy with distance, while Spells do not use Accuracy.

What Accuracy does

Current rules

For a normal player Attack, build Accuracy from levels, Dexterity, equipment, passives, and skill effects, apply the distance penalty, then compare the result with the target's Evasion. Accuracy also lowers the target's chance to Deflect. Effects that Always Hit or cannot be Evaded bypass the ordinary Accuracy and Evasion calculation.

Attacks use Accuracy: An Attack normally checks the attacker's Accuracy against the target's Evasion to determine whether it Hits. Spells do not use this Accuracy check.
Levels and Dexterity provide the base: The official 0.3.0 update set player gain to 6 Accuracy Rating per level. Current extracted game data gives 8 Accuracy Rating per Dexterity, replacing the older published value of 6 per Dexterity.
Chance to Hit formula: The community-documented uncapped chance to Hit is Accuracy multiplied by 125, divided by Accuracy plus 0.3 times defender Evasion. Normal chance to Hit cannot be lower than 5% and normally cannot exceed 100%.
Distance applies a less multiplier: Player Attacks have no distance penalty within 2 metres. The penalty then increases linearly, reaching 90% less Accuracy at 9 metres or farther. Distance is measured from the origin of the damage to the target.
Enemies have no inherent range penalty: Enemy Attacks do not normally lose Accuracy with distance. Specific effects such as Stay Light, Use Cover or Vigilant View can impose the player-style distance penalty on enemies.
Always Hit bypasses the calculation: Always Hit and Can't be Evaded set the ordinary chance to Hit to 100% without using attacker Accuracy or defender Evasion. A defender that Cannot Evade produces the same result from the defender side.
Player Minions always Hit: Player Minion Attacks always Hit and do not require Accuracy. This rule was introduced in the official 0.3.0 update.
Accuracy also opposes Deflection: Deflection is a separate defence after the Attack connects. Higher attacker Accuracy lowers the defender's Deflection chance; the current formula is 150 multiplied by one minus Accuracy divided by Accuracy plus 0.12 times Deflection Rating, capped at 95% chance to Deflect.
Amazon can use excess chance: The Amazon's Critical Strike notable allows chance to Hit with Attacks to exceed 100% and grants additional Critical Hit Chance equal to 25% of the excess. Under the documented Accuracy formula, uncapped chance to Hit approaches but does not exceed 125%.

Accuracy sources and exceptions

Base Accuracy

Player levels and Dexterity supply the starting pool before flat, increased, more, less, and distance modifiers are applied.

Flat and increased Accuracy

Equipment, passive skills, modifiers, runes, idols, and other explicit sources add flat Accuracy Rating or scale the applicable total.

Heightened Accuracy

Heightened Accuracy I gives a supported Attack 50% more Accuracy. Tier II also makes the supported Attack Always Hit enemies on full Life.

Precision

Precision supports a Persistent Buff and grants increased Accuracy while that supported skill is active. The current tiers use different Spirit costs and Accuracy values.

War Banner

The placed Banner Aura grants nearby allies increased Accuracy Rating together with its Attack damage and Attack Speed benefits.

Accuracy is Doubled

Lycosidae and Resolute Technique double Accuracy Rating. Resolute Technique also prevents Critical Hits; it no longer makes Hits unable to be Evaded.

Enemy distance penalty

Vigilant View and the Tactician notable Stay Light, Use Cover make enemy Accuracy fall with distance, but both also cap the user's maximum chance to Evade at 50%.

Cannot Evade

Carved Cunning can make enemies on full Life unable to Evade Hits from the socketed helmet's user. This is a conditional bypass rather than more Accuracy.

Limits and exceptions

7 rules

Accuracy determines whether an Attack Hits. It does not directly increase the damage of a Hit that already connects.
Spells do not use Accuracy, even when their effects travel as Projectiles.
Player Minion Attacks always Hit and do not need Minion Accuracy under the current rule.
The distance penalty is a less Accuracy multiplier, not Projectile damage falloff.
Chance to Hit and chance to Deflect are separate checks. A connected Attack can still have part of its damage prevented by Deflection.
A character-panel estimate depends on the assumed target and distance and may not describe every encounter.
The current 8 Accuracy per Dexterity value comes from extracted current game data; the older official 0.3.0 notes and stale prose still show 6.

Related mechanics

MechanicAttack

An Attack is a skill with the Attack tag. It normally takes its base damage, attack speed, and base Critical Hit Chance from an equipped Martial Weapon, unless the skill states a different rule.

MechanicSpell

A Spell is a skill with the Spell tag. Any base damage, Cast Time, and base Critical Hit Chance it lists come from the skill rather than the inherent damage, Attack Speed, or base Critical Hit Chance on a weapon.

MechanicEvasion

Evasion Rating grants an entropy-based chance to Evade enemy Hits completely. The actual chance compares the defender's Evasion Rating with the Accuracy Rating of the attacker.

MechanicMelee

Melee Attacks directly hit with a Strike or deal Melee damage through a Slam. They usually scale from a Martial Weapon or Unarmed base, but Melee is not a damage type and does not include Projectiles created by the Attack.

MechanicDexterity

Dexterity is a primary Attribute used for equipment and gem requirements, especially Evasion and range-aligned equipment. Each point of Dexterity inherently grants 8 Accuracy Rating.

MechanicStrike

A Strike is a Melee Attack that directly hits with a weapon or body part. Strike and Slam are mutually exclusive classifications, and Melee Strike Range affects how far a Strike can directly reach.

MechanicSlam

A Slam is a Melee Attack that deals damage through an area instead of directly Striking an enemy. Slams always have the AoE tag, remain Melee damage, and do not count as Strikes.

MechanicDeflect

Deflection Rating gives a chance to Deflect damage from Hits. A normal Deflection prevents 40% of the Hit damage, while the chance depends on your Deflection Rating and the attacker's Accuracy Rating.

MechanicBlind

Blind is a debuff that gives the affected target 20% less Accuracy Rating and 20% less Evasion Rating for 4 seconds unless another duration is specified.

MechanicSmoke Cloud

A Smoke Cloud is a 2 metre area that Blinds enemies standing inside it unless the source specifies another radius. It does not deal damage or make its creator invisible.
