This page is about the skill gem. For the unique monster, see Herald of Thunder (unique monster).

Herald of Thunder is a Herald skill. It reserves mana to grant added lightning damage to attacks and spells. Whenever you kill a shocked enemy, it will activate an effect where lightning bolts strike nearby enemies for a duration.

Mechanics[]

Similar to the Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. and Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. skill gems, Herald of Thunder has two separate effects.

The first effect adds x-y lightning damage to both spells and attacks. Damage dealt by this effect can not shock.

The second effect is triggered when a shocked enemy is killed. A Storm will strike enemies and destructible objects within Herald of Thunder's radius for its duration dealing lightning secondary damage. This storm remains centered on the character's location if the character moves. Damage dealt by the storm cannot inflict shock, and is not an area of effect.

The storm will strike an enemy or destructible object every 250ms, but will prioritise targets that have been struck fewer times.

The storm from Herald of Thunder applies to enemies killed by attacks as well as spells, but not if they are killed by minions, traps, mines, or totems.

Interactions[]

  • Elemental Damage: Elemental and lightning damage modifiers affect both the on-hit and on-kill effects of Herald of Thunder. Added damage from support gems such as Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. and Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. only applies to Herald of Thunder's storm.
  • Casting and Spell Interactions: Because Herald of Thunder's lightning bolts is secondary damage and not spell damage it is not directly affected by items, support gems, or passive skills which specifically modify spells.
  • Area of Effect: AoE modifiers like Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. and Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. affect the radius in which Herald of Thunder's storm can strike targets. Lightning bolts are not AoE damage, therefore Area Damage modifiers don't affect the storm's damage.
  • Duration: Duration modifiers like Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. and Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. affect the duration of the storm.
  • Auras, Buffs and Mana Reservation: Like Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. and Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.., Herald of Thunder is not an aura and does not receive bonuses from aura nodes, items, or support gems. It does reserve mana however, and it therefore benefits from reduced Mana Reserved modifiers.
  • Quality: Herald of Thunder's increased lightning damage quality bonus is global, meaning that it affects the character's lightning damage from all sources, not only Herald of Thunder.
  • Cannot Apply Shock: Herald of Thunder's on-kill effect cannot apply Shock. However, if Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. is equipped, the storm can apply Freeze.
