Not to be confused with the unique monster, Herald of Ashes.
Herald of Ash is 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.
Extra Fire Damage: This modifier adds fire damage to all non-damage-over-time sources, including those from spells, attacks, 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.[1] 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 SupportExceptional, Support Icon: + Level: (1-3) Cost & Reservation Multiplier: 120%Supports any skill gem.
