Bleeding is an Ailment that deals Physical damage over time, and lasts 5 seconds by default. Damage from Bleeding bypasses Energy Shield

Bleeding deals an extra 100% damage while the target is moving, or if the Bleeding is Aggravated.

Physical damage from Hits Contributes to Bleeding Magnitude.

Damage does not Contribute to Bleeding chance, so it cannot be inflicted without an explicit source of Bleeding chance.

The base Magnitude of Bleeding is Physical damage per second equal to 15% of the Pre-mitigation Physical damage of the Hit that inflicted it. This magnitude is not further affected by any modifiers to the damage you deal.

Modifiers and Debuffs that affect the enemy's ability to mitigate damage (such as Shock) can affect the damage the enemy takes from Bleeding, but any such modifiers that specifically apply to Hit damage (such as Armour Break) do not affect Bleeding damage.

Chill is an Ailment that Slows the afflicted target, and lasts 2 seconds on players or 8 seconds on non-players by default. Chill Magnitude depends on the Chilling damage dealt relative to the target's Elemental Ailment Threshold, with a minimum of 30% and a default maximum of 50%.

Cold damage from Hits can Chill by default, and does not require a chance to inflict Chill. However, Chills smaller than 30% will be ignored, so small Hits can fail to Chill.

Ignite is an Ailment that deals Fire damage over time, and lasts for 4 seconds by default.

The chance for a Hit to Ignite a target is determined by the total Magnitude of Flammability on the target, including the amount added by that Hit.

Fire damage from Hits Contributes to the Magnitude of Ignite, so Hits dealing more Fire damage inflict stronger Ignites.
The base Magnitude of Ignite is Fire damage per second equal to 20% of the Fire damage dealt by the Hit that inflicted it. This is calculated using the final damage dealt by the Hit, but not any modifiers on the target that affect how much damage they will take from the Hit. This Magnitude is not further affected by any modifiers to the damage you deal.

Modifiers and Debuffs that affect the enemy's ability to mitigate damage (such as Shock) can affect the damage the enemy takes from Ignite, but any such modifiers that specifically apply to Hit damage (such as Penetration) do not affect Ignite damage.

Flammability is a Debuff that provides the chance for Hits to Ignite the target. It is not itself an Ailment, but is closely associated with Ignite, which is.

Fire damage from Hits Contributes to the Magnitude of Flammability, so Hits that deal more Fire damage will Ignite more often.

The base Magnitude of Flammability is 1% chance to Ignite the target for every 5% of the target's Ailment Threshold dealt as Fire damage. Flammability from a Hit is applied before that hit checks whether it should Ignite the target, and so will affect that chance for that Hit to Ignite.

Since chance for Hits to Ignite comes from Flammability on the target, modifiers which increase the chance to inflict Ailments will increase the Magnitude of Flammability inflicted.

Effects which do not Hit targets, but Ignite as if they had, such as Ignited Ground, also inflict Flammability, but do not roll a random chance to Ignite. Such effects will only Ignite once the total Flammability on the target reaches 50%.

Multiple instances of Flammability stack, raising the chance for Hits to Ignite the target up to 100%. Each instance of Flammability has its own independent duration, lasting 8 seconds by default.

Poison is an Ailment that deals Chaos damage over time, and lasts 2 seconds by default. Damage from Poison bypasses Energy Shield.

Physical and Chaos damage from Hits Contribute to Poison Magnitude.

Damage does not Contribute to Poison chance, so it cannot be inflicted without an explicit source of Poison chance.

The base Magnitude of Poison is Chaos damage per second equal to 20% of the Pre-mitigation Physical and Chaos damage of the Hit that inflicted it. This magnitude is not further affected by any modifiers to the damage you deal.

Modifiers and Debuffs that affect the enemy's ability to mitigate damage (such as Shock) can affect the damage the enemy takes from Poison, but any such modifiers that specifically apply to Hit damage (such as Penetration) do not affect Poison damage.

Modifiers to the Effect of Buffs or Debuffs usually come from the target it affects and are multiplicative with modifiers to the Magnitudes of the Buff or Debuff, which come from its creator.

Enemies covered in Oil have their movement speed Slowed, are inflicted with Exposure and have 200% more Magnitude of Flammability inflicted on them.

Ignited Ground or Detonator Skills will Ignite Oil-covered enemies. This removes the Oil, but the Exposure will remain for the duration of that Ignite.

By default, specific Ailments are calculated based on only specific damage types, such as only the Fire damage of a Hit mattering when inflicting Ignite.

Allowing another damage type to contribute to an Ailment means that all damage of the relevant types is summed when performing calculations for that Ailment.

For Ailments that use Hit damage to determine Ailment chance or buildup, this means that the damage type becomes capable of inflicting that Ailment. For Ailments that only use Hit damage to determine Ailment Magnitude (i.e. Bleeding and Poison), you still need a way to apply those Ailments (e.g. a source of Bleeding or Poison chance).

This is modifier applies to Debuffs you inflict that Slow enemies, and scales only the specific Magnitude that slows the target. It will not affect any other Magnitudes that Debuff has if it does other things in addition to the Slow.

Impale is a Debuff inflicted by Hits, which stores 30% of the Pre-mitigation Physical Hit damage of the Impaling hit as its Magnitude.

Subsequent Attack Hits against Impaled targets will Extract the Impale debuff. When this occurs, the Magnitude of the Impale is added to the Pre-mitigation Physical damage of that attack hit.

A maximum of 60 Impale Debuffs can be present on a target at once. If multiple Impales are present on a target, each Attack's Hit only Extracts and benefits from the strongest one of them.

Riven Armour is a Debuff inflicted by Hits, which stores 5% of the Pre-mitigation Physical Hit damage of the Hit that inflicts it as its Magnitude.

The inflicter's subsequent Attack Hits against the target will gain additional unscaleable added Physical Damage equal to that magnitude.

Enemies with Riven Armour cannot get their Armour Broken further.

While affected by Unravelling, your Chaos Damage randomly either also contributes to Freeze buildup, Flammability and Ignite Magnitudes, or Shock chance - changing which it contributes to every two seconds.

Broken Stance is a Debuff inflicted by Hits, which stores 10% of the Pre-mitigation Physical Hit damage of the Hit that inflicts it as its Magnitude.

The inflicter's subsequent Hits against the target will gain additional unscaleable added Physical Damage equal to that magnitude.

Enemies with Broken Stance cannot be Dazed again.

When Igniting a target which has already been Ignited by the same use of this Skill, the existing Ignite is removed to boost the new Ignite, multiplying its Magnitude by the total number of Ignites compounded this way.
