Hit

Bleeding is a damaging Ailment that deals Physical damage over time and bypasses Energy Shield. It lasts five seconds by default and requires an explicit chance or effect that can inflict Bleeding.

Poison is a damaging Ailment that deals Chaos damage over time and bypasses Energy Shield. It lasts two seconds by default and requires an explicit chance or effect that can inflict Poison.

Ignite is a damaging Elemental Ailment that deals Fire damage over time for four seconds by default. A Hit's chance to Ignite comes from the target's total Flammability, including Flammability applied by that same Hit.

Chill is a non-damaging Elemental Ailment that slows action speed. Cold Hits can Chill without a separate application chance, but a calculated Chill below 30% Magnitude is discarded.

Freeze is a non-damaging Cold Ailment that prevents a target from moving or acting. Cold Hits can Freeze directly or add Freeze Buildup, and reaching 100% Buildup makes the target Frozen.

Shock is a non-damaging Lightning Ailment that makes a target take 20% increased damage by default. Lightning Hits gain a chance to Shock based on post-mitigation damage relative to the target's Elemental Ailment Threshold.

Electrocution is a non-damaging Lightning Ailment that interrupts a target and prevents it from performing actions. It lasts five seconds by default, but ordinary Lightning damage cannot build Electrocution without an explicit enabling effect.

Elemental Ailment Threshold is the defensive comparison value used when Elemental Hits try to apply Ignite, Chill, Freeze, Shock, or Electrocution. A higher threshold makes those ailments harder to apply and reduces Freeze and Electrocution Buildup received.

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.

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.

Damage is classified on three independent axes: source, delivery, and type. A component can come from an Attack, Spell, Thorns, or another source; deal a Hit or damage over time; and deal Physical, Fire, Cold, Lightning, or Chaos damage.

Armour reduces applicable damage from Hits. By default it applies only to Physical Hit damage, and its reduction depends on the raw damage of each Hit rather than providing one fixed percentage.

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.

Energy Shield is a rechargeable defensive resource that normally protects Life. Damage is mitigated first, then removes Energy Shield before Life unless the damage or another effect explicitly bypasses it.

Block prevents the damage of a blockable Hit. Passive Block rolls the character's Block chance for each eligible Hit, while active Block from a raised shield guarantees a block from the protected direction under that skill's rules.

Stun interrupts the target's current action and briefly prevents it from acting. Path of Exile 2 has two related systems: Light Stun is rolled from the damage of one Hit, while Heavy Stun is caused by filling a separate buildup bar.

Stun Threshold is the target-side reference used to determine Light Stun chance and Heavy Stun buildup. Raising your own threshold makes incoming Stuns less likely, while lowering an enemy's threshold makes that enemy easier to Stun.

Heavy Stun is the longer disable caused when an enemy's Heavy Stun buildup bar fills. Eligible Hits add buildup based on their damage, and the bar begins to empty after buildup has not been applied for a period.

Armour Break lowers a target's Armour by a specified amount. Reaching 0 applies Fully Broken Armour, which removes the target's Armour benefit and has additional effects against monsters.

Gain is wording used by several different mechanics. On a damage line, gaining damage as extra creates an additional amount of the named output damage without removing the original damage.

Physical damage is one of the five Damage Types. It is the most common and the only one reduced by Armour, rather than by a Resistance.

Elemental Damage is the collective name for Fire, Cold, and Lightning Damage. A modifier to Elemental Damage can scale all three types, but each part is still mitigated by its matching Resistance and keeps its own ailment rules.

Fire Damage is one of the five damage types. Fire Hits apply Flammability, which supplies chance to Ignite, while Fire Resistance mitigates Fire Hits and Fire damage over time separately.

Cold Damage is one of the five damage types. Cold Hits can Chill and build Freeze, but Chill Magnitude, Freeze Buildup, and Freeze Duration are separate values, and Cold damage from Hits cannot build Heavy Stun.

Lightning Damage is one of the five damage types and one of the three Elemental damage types. Lightning Hits can Shock by default, while Electrocution requires a Skill, item, support, or other effect that explicitly enables Electrocution Buildup.

Critical Hits deal +100% extra damage (i.e. twice as much damage) by default. Critical Damage Bonuses can further modify this value.

A Support Gem modifies one skill when socketed into that skill in the Skills Panel. Compatibility, Support Category, attribute capacity, socket count, and any cost or reservation multiplier all matter before the support can apply.

Area of Effect, usually shortened to AoE, describes a skill component that applies to targets inside an area instead of selecting only one target. The area can be a circle, cone, line, ring, or another shape defined by the skill.

A Projectile is a moving entity created by an Attack or Spell. Projectile describes delivery, not the source type or damage type, so the Projectile can still be an Attack or Spell and can deal any supported damage type.

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.

Chaos is one of the five damage types. Chaos Resistance reduces it, and ordinary Chaos damage removes twice its damage value from Energy Shield instead of bypassing Energy Shield by default.

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.

A Sustained skill deals many Hits over time and rolls Critical Hits independently each time it damages an enemy. The tag describes this repeated damage behavior, not a universal duration, frequency, or damage bonus.

A Payoff skill gains a powerful extra effect when it Hits an enemy affected by a specified Debuff. It often Consumes that Debuff, and it cannot inflict the same Debuff that enables its Payoff effect.

Fire Resistance reduces Fire damage taken. It is tracked independently from the other damage-type Resistances, has a default maximum of 75%, and can have a different uncapped value from the value currently used for mitigation.

Cold Resistance reduces Cold damage taken. It is tracked independently from the other damage-type Resistances, has a default maximum of 75%, and can have a different uncapped value from the value currently used for mitigation.

Lightning Resistance reduces Lightning damage taken. It is tracked independently from the other damage-type Resistances, has a default maximum of 75%, and can have a different uncapped value from the value currently used for mitigation.

Chaos Resistance reduces Chaos damage taken. It is tracked independently from the other damage-type Resistances, has a default maximum of 75%, and can have a different uncapped value from the value currently used for mitigation.

Damage Conversion changes part or all of one Hit damage type into another. In Path of Exile 2, the converted portion uses only its new damage type for scaling, mitigation, and default ailment contribution. It no longer keeps the old damage type.

Rage is a combat resource that inherently grants 1% more Attack Damage per point. Characters have 30 maximum Rage by default. Rage generation is limited to one Hit every 0.5 seconds, and inherent Rage loss begins after four seconds without gaining Rage or taking damage.

Recoup is recovery created by damage from a Hit. A percentage of eligible damage is recovered as the stated resource over eight seconds by default. Recoup does not prevent the original damage, does not trigger from damage over time, and cannot save a character from a Hit that is already lethal.

Recently means during the previous four seconds. It creates a rolling condition based on a named event such as being Hit, dealing a Critical Hit, spending Mana, consuming a Charge, reloading, Blocking, or Dodge Rolling. The event, subject, and verb must all match the modifier.

Flammability is a stackable Debuff that builds from contributing damage and determines the chance for Hits to Ignite. It is not itself an Ailment, and its magnitude is separate from the magnitude of the resulting Ignite.

Exposure is a Debuff that lowers one or more of the target's Resistances. It changes the target's actual resistance, can reduce it below zero, and can improve both Hit and non-Hit damage that uses the affected resistance.

Staged Skills gain discrete stages and use the current stage count to change an effect. The way stages are gained, their maximum, what each stage improves, and when they are spent or removed are defined by the individual Skill.

Herald Skills are Persistent Buffs that reserve Spirit and provide a payoff after a qualifying enemy death or condition. Each Herald has its own trigger, damage component, ailment interaction, and scaling requirements.

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.

Life Leech recovers Life from a percentage of damage dealt by a Hit. A normal Life Leech instance delivers its recovery over one second, subject to the source's eligible damage type and the monster's Leech Resistance.

Each Critical Weakness stack gives Hits against the affected target +0.5% to Critical Hit Chance. The debuff can have up to 20 stacks.

Guard is a temporary buffer that takes damage from Hits before Life or Energy Shield. It ends when its amount is depleted or its duration expires.

Parry is the active Block skill granted by Bucklers. Hold it while facing an enemy to block an eligible Hit, retaliate with a Physical sweep, and apply the Parried debuff.

A Lucky value is rolled twice and the better result is used. Luck applies only to the roll named by the modifier, such as Hit damage, Critical Hit chance, Block chance, or Deflect chance.

An Unlucky value is rolled twice and the worse result is used. The modifier affects only the named roll, such as enemy Hit damage, Physical Hit damage, Lightning Hit damage, Critical Hit chance, or Evasion chance.

Knockback displaces an enemy when a Hit applies it. Standard Knockback pushes the enemy away from you, while Knockback Distance modifiers change how far the enemy would be moved.

Onslaught is a Buff that grants 20% increased Skill Speed and 10% increased movement speed. A temporary source normally grants it for four seconds unless that source states another duration or ties it to an ongoing effect.

Soul Eater consumes Souls from nearby deaths and grants 1% increased Skill Speed per Soul, up to 50 Souls. If no new Soul is eaten for four seconds, one Soul is lost every 0.5 seconds until another Soul is eaten or the count reaches zero.

Aggravating any Bleeding is a trigger condition that succeeds only when a Hit with the specified weapon directly changes at least one existing Bleeding Debuff from not Aggravated to Aggravated.

Blood Loss is the accumulated amount of Physical damage over time a target has actually taken. Bleeding and Corrupted Blood both contribute, and the amount appears as a darker red section of the target's life bar.

Unholy Might is a Buff that grants 30% of all applicable damage as extra Chaos Damage. It creates an additional Chaos portion and does not remove or convert the original damage.

Runefather's Challenge is a debuff that raises an affected enemy's Power by 5. It is applied by Eyes of the Runefather or by a shield carrying Legacy of A Worthy Foe.

Runefather's Boast is a stacking Buff granted by Eyes of the Runefather when you kill an enemy affected by Runefather's Challenge. Each stack grants +1 Armour, +1 Evasion Rating, and +1 Stun Threshold.

Decimating Strike makes a Hit against a Full Life enemy remove a random 5% to 30% of its Life immediately before the Hit's damage is applied. It is granted by the Witchhunter notable Judge, Jury, and Executioner and by Aerisvane's Wings.

Reveal Weaknesses highlights random sections of a Rare or Unique enemy's Life bar. The highlighted sections total 45% of maximum Life. While the enemy's current Life is inside one of those sections, it has an Open Weakness.

You are Surrounded when at least five enemies are within 3 metres of your character. Surrounded is a condition, not a Buff: it has no duration, does not stack, and grants nothing by itself. Items, passive skills, and Support Gems check whether the condition is currently true and apply their own listed effects while it is.

Overkill damage is the part of a killing Hit that exceeds the enemy's remaining Life. It is a measured amount used by effects such as Herald of Ash and Trampletoe, not an automatic bonus applied to every kill.

Unbound Potential is a stacking buff created by The Unleashed body armour. It converts the Runic Bindings built by Spell Hits in Human form into increased Damage, Armour, and Energy Shield for a shapeshifted character.

Shatter is the corpse-destruction result when a Frozen monster is killed. Shatter does not deal damage by itself, but Herald of Ice, Frozen Vortex, unique items, and other effects can change what qualifies or add a payoff when the event occurs.

Thorns is Hit damage dealt as a separate hit. By default, a character with Thorns retaliates when an enemy hits them with a Melee Attack.
