Harness the Power of Double Herald in Path of Exile 2: A Comprehensive Guide
The Double Herald setup in Path of Exile 2 (PoE 2) combines Herald of Ice and Herald of Thunder for devastating screen-clearing potential. This guide details how to implement and understand this powerful technique.
How to Use Double Herald (Herald of Ice + Herald of Thunder)
Four key elements are required:
Herald of Ice Skill Gem with 
Lightning Infusion Support Gem.
Herald of Thunder Skill Gem with 
Cold Infusion Support Gem (and ideally 
Glaciation).- 60 Spirit.
- A method to inflict Cold damage.
Remember to activate both Heralds in your skill menu.
Effective Cold damage sources to initiate the chain reaction include:
- Monk's Ice Strike.
- Passive skills boosting Freeze buildup.
- Gloves/weapons with flat cold damage.
Against the Darkness Time-Lost Diamond Jewel (+Cold damage%).
How Herald of Ice and Thunder Synergize
The synergy is based on their unique interactions:
- Herald of Ice activates upon shattering a frozen enemy, creating a cold AoE explosion. Crucially, its cold damage cannot freeze, preventing self-perpetuation.
- Herald of Thunder activates upon killing a shocked enemy, unleashing damaging lightning bolts. Similarly, it cannot inflict shock independently.
The key is the damage conversion: Lightning Infusion on Herald of Ice converts some damage to lightning (which can shock), and Cold Infusion on Herald of Thunder converts some damage to cold (which can freeze). This allows them to trigger each other in a chain reaction.
While theoretically infinite, in practice, the chain reaction usually lasts one or two cycles due to the need for continuous enemy presence. Breaches, with their high enemy density, are ideal for maximizing this setup's effectiveness.
To initiate: Freeze and shatter an enemy using a cold skill (like Ice Strike). This triggers Herald of Ice, which shocks, triggering Herald of Thunder. Prioritizing Herald of Ice is recommended because Freeze is easier to inflict than Shock, and Herald of Thunder's lightning bolts have better range.
