Perfect Agony - Path of Exile

Perfect Agony is a keystone passive skill. It causes a percentage of Critical Strike Multiplier to apply to Ailments, but reduces damage dealt with hits.

  • Modifiers to Critical Strike Multiplier also apply to Damage over Time Multiplier for Ailments from Critical Strikes at 50% of their value
  • (Ailments that deal damage are Bleeding, Ignited, and Poisoned)
  • 30% less Damage with Hits

The only way to increase the critical strike multiplier on ailments is with the Perfect Agony keystone.

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.

Critical strike multiplier

Critical strikes deal more damage than normal, based on critical strike multiplier. All characters have a base critical strike multiplier of 150%. The damage will be multiplied according to

CriticalStrikeDamage = Damage * (BaseCriticalStrikeMultiplier + AdditionalCriticalStrikeMultiplier)

Where Damage is the base damage, BaseCriticalStrikeMultiplier = 150% and AdditionalCriticalStrikeMultiplier is the sum of all +#% to Critical Strike Multiplier.

This multiplier will be applied to all damage types of a hit. For instance, with +100% to Critical Strike Multiplier, if the player scores a critical strike with an attack that normally deals 100 physical damage and 10 cold damage, he will instead deal 250 physical damage and 25 cold damage.

Critical strike multipliers do not affect the critical strike multiplier on ailments, including global critical strike modifiers. Ailments have a base 150% multiplier when applied by a critical strike. The only way to increase the critical strike multiplier on ailments is with the Perfect Agony keystone.
