Ailment

An ailment is a detrimental effect associated with one or more damage types.

Ignite, chill, freeze and shock are collectively referred to as elemental ailments.

List of ailments

Ailment	Associated with	Effect
Bleed	Physical	Bleed causes the affected target to take physical damage over time. The amount of damage is greater while the target is moving. Bleed can only be inflicted by physical damage from attacks.
Poison	Physical and chaos	Poison causes the affected target to take chaos damage over time. Poison can stack multiple times on a single target.
Ignite	Fire	Ignite causes the affected target to burn, taking fire damage over time.
Chill	Cold	Chill slows all actions of the affected target. Cold damage always inflicts chill.
Freeze	Cold	Freeze prevents the affected target from taking actions.
Shock	Lightning	Shock causes the affected target to take increased damage from all sources.

Mechanics

Ailments are in many ways similar to debuffs. The most notable difference is that ailments are associated with damage types, whereas debuffs are associated with skill effects. Modifiers to skill effect duration affect the duration of debuffs applied by skills, but not the duration of ailments.

There is no limit on the number of different ailments a target can have at any given time.

Application by damage

Ailments can be applied by hits of damage.

Each ailment is associated with one or more damage types. A damaging hit has the potential to inflict any ailments associated with the types of damage dealt. For example, a hit of physical and fire damage has the potential to inflict bleed, poison and ignite. Bleed has an additional restriction: It can only be applied by attacks.

The damage type associations for ailments may be changed by certain effects. As an example, The Three DragonsThe Three Dragons
Golden MaskEvasion: (96-103)
Energy Shield: (20-22)Requires Level 35, 40 Dex, 40 Int+(26-30)% to all Elemental Resistances
Your Fire Damage can Shock but not Ignite
Your Cold Damage can Ignite but not Freeze or Chill
Your Lightning Damage can Freeze but not Shock"The ice seared his naked feet
As the lightning stilled his heart,
But it was the flames upon his lover's face
That roused him to vengeance."
- From 'The Three Dragons' by Victario of Sarn changes which damage types have the potential to inflict elemental ailments.

A hit of damage also carries a property for each ailment that gives the hit a chance to inflict that ailment. By default, the chance to inflict most ailments is 0%. Any damaging hit has a 100% chance to inflict chill. Critical strikes have a 100% chance to inflict ignite, freeze and shock. Some skill and support gems include modifiers that grant additional chance to inflict certain ailments. Additional chance to inflict ailments can also be gained from passive skills and equipment.

Targets may also have immunity or a chance to avoid certain ailments.

To summarize, an ailment is applied to the target if:

• The hit of damage consists of damage types that have the potential to inflict the ailment
• The chance to inflict the ailment is successful
• The target fails to avoid the ailment
• The target is not immune to the ailment
• Any other conditions are met

Application by other means

Ailments can be applied in ways other than direct hits of damage.

• Elemental proliferation causes elemental ailments to spread to other targets within a radius.
• Certain ground effects apply ailments.

Damage with ailments

Ignite, bleed and poison are damaging ailments. A damaging ailment deals damage over time based on the base damage of the skill that inflicts the ailment. Only the damage types that have the potential to inflict a damaging ailment are used as a basis for calculating the damage over time for that ailment. From a previous example, a hit of physical and fire damage has the potential to inflict bleed, poison and ignite. In this example, only the fire portion of the base damage is considered for ignite.

Damage with hits and damage with ailments are calculated separately and have different modifiers. Modifiers to damage with ailments do not contribute to the damage of attacks or spells. Similarly, modifiers to attack damage and spell damage do not contribute to damage with ailments. Modifiers to damage with weapons, melee damage, projectile damage and area damage do not apply to ailments under any circumstances. Modifiers to damage with ailments, damage over time modifiers, and generic damage modifiers all apply to damaging ailments. Modifiers to damage with specific ailments apply only to those ailments. Damage type modifiers apply to ailments that deal those types of damage. Additionally, burning damage modifiers apply to ignite, since 'burning damage' simply means fire damage over time. Resistances apply to damage of the corresponding types dealt by ailments.

The damage multiplier for ailments from critical strikes exists independently from the critical strike multiplier used for hits. A character's base damage multiplier for ailments from critical strikes is 150%. There currently exist no modifiers to this stat. However, the Perfect Agony keystone applies a percentage of modifiers to critical strike multiplier to the damage multiplier for ailments from critical strikes.

3.0.0

Bleeding and Poison are now both considered 'Ailments'. This means their durations are only affected by increased bleeding/poison duration modifiers, and the new ailment duration modifier (they are not elemental ailments, so are not affected by the existing modifier to elemental ailments). We now only refer to 'Ailments' rather than the longer 'Status Ailments'. The pre-existing 'Elemental Status Ailments' are now referred to as 'Elemental Ailments', and cases where 'Elemental' was left off because there were previously no non-elemental ailments have been corrected. There are now separate reminder texts for Elemental Ailments and for Ailments.
