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

Herald of Ash is a Herald skill. It reserves mana to grant extra fire damage based on physical damage. Enemies you kill while Herald of Ash is active will apply a burn to nearby enemies, based on overkill damage.

Skill functions and interactions

• Extra Fire Damage: This modifier adds fire damage to all hits, including those from attacks, spells, and secondary damage sources.

• Burn on kill: While Herald of Ash is active, when you kill with a hit, enemies near the kill receive a burning debuff based on the overkill damage. Overkill damage refers to total excess damage of the killing hit over the monster's remaining Life and Energy shield, including non-fire damage. The burning damage is affected by increased/more Burning Damage and increased/more Damage Over Time, as well as damage over time multipliers that apply to all damage or Fire damage. The debuff is not an Ignite, and is not affected by modifiers to Ignite or Ailments.

• More Burning Damage: The more Burning Damage is not global. It only affects the burning debuff created by Herald of Ash itself.

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

• Culling Strike: Hits that leave enemies with less than 10% of their life and then kill through culling strike have no overkill damage. (Though the culling strike modifier does not prevent overkilling in general.)

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

Version history

Version	Changes
3.25.0	Buff no longer grants more Spell Fire Damage. The buff now grants 15% of your Physical Damage as Extra Fire Damage at gem level 1, scaling up to 20% at gem level 20 (previously 15% at all gem levels).
3.23.0	Quality now provides "Base Burning Damage is an additional 0-5% of Overkill Damage", instead of causing the Buff to grant 0-15% increased Fire Damage.
3.11.1	Clarified that the "x% increased Fire Damage" from Herald of Ash's quality stat is dependent on having the Herald of Ash buff.
3.11.0	The visual effects have been improved.
3.4.0	Now instant by default and can therefore be used while moving. All instant skills now have cooldown 1 second or less. Instant skills cannot be supported by Spell Echo and will not be cast a second time by similar effects (such as from the Echoing Shrine).
3.2.0	Herald of Ash now also provides more Spell Fire Damage, and can trigger the overkill burn from spells.
3.0.0	Secondary effect no longer ignites. Instead, enemies near slain enemies are burned based on the overkill damage. Added Herald gem tag.
2.0.0	Radius reduced by 16.5% (from 12 to 10) and base overkill damage reduced to 80% (from 100%).
1.2.0	Herald of Ash has been added to the game.
