Not to be confused with the unique monster, Herald of Ashes.

Herald of Ash is a Herald skill. It reserves mana to grant additional fire damage based on physical damage to attacks and more fire damage to spells. Enemies you kill while Herald of Ash is active will explode and burn nearby enemies for overkill damage.

Skill functions and interactions

• Extra Fire Damage: This modifier adds fire damage to all non-damage-over-time sources, including those from attacks, spells, and traps. The amount added is equal to 15% of the damage source's physical damage.

• Burn on kill: While Herald of Ash is active, when an enemy is killed, enemies within a radius from the killed enemy are burned based on the overkill damage. Overkill damage refers to total excess damage of the killing hit, including non-fire damage. The burning damage is affected by increased Burning Damage and increased Damage Over Time. This damage cannot be reflected.

• Fire Damage: The increased Fire Damage from quality applies globally to all fire damage, including the extra fire damage effect of Herald of Ash.

• More Burning Damage: Despite the more Spell Fire Damage the more Burning Damage is not global. It only affects the burn created by itself.

• Support gems: Any support gems (with the exception of Enhance SupportEnhance SupportSupport

• Area of Effect: Area of Effect modifiers from passives, items, and gems affect the radius of the on-kill effect.

• Culling Strike: When using an attack with culling strike, the overkill effect will only apply if the damage from the killing hit would have taken the monster to less than 0 life.

Strategy

• In the case where enemy death occurs uniformly at random with respect to damage dealt, the chance of an enemy dying from a particular hit is proportional to the damage the hit deals. The mean overkill damage for that hit is half the damage of the hit. This makes the mean overkill damage overall equal to

 0.5 * (mean damage2) / mean damage
