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 this technique and explains its mechanics.
How to Use Double Herald (Herald of Ice + Herald of Thunder)
This powerful strategy requires four key elements:
Herald of Ice Skill Gem linked with 
Lightning Infusion Support Gem.
Herald of Thunder Skill Gem linked with 
Cold Infusion Support Gem (and ideally 
Glaciation).- 60 Spirit.
- A method for inflicting Cold damage.
Remember to activate both Heralds in your skill menu.
Effective ways to initially trigger Herald of Ice include:
- Monk's Ice Strike (highly effective).
- Passive skills boosting Freeze buildup.
- Gloves or weapons with flat cold damage.
Against the Darkness Time-Lost Diamond Jewel (+Cold damage%).
How Herald of Ice and Thunder Synergize
Herald of Ice activates when an enemy is Shattered (freezing then attacking). Crucially, Herald of Ice's cold damage cannot Freeze, preventing self-perpetuating chains.
Herald of Thunder activates upon killing a Shocked enemy, unleashing electrical damage. Similarly, it cannot inflict Shock independently.
The synergy lies in the Support Gems: Lightning Infusion converts a portion of Herald of Ice's damage to Lightning (which can Shock), while Cold Infusion converts part of Herald of Thunder's damage to Cold (which can Freeze).
This creates a chain reaction: Herald of Ice (via Lightning) Shocks, triggering Herald of Thunder; Herald of Thunder (via Cold) Freezes, triggering Herald of Ice, and so on. While ideally infinite, this chain usually lasts one or two cycles due to enemy density. Breaches are particularly effective due to high enemy counts.
To initiate, Freeze and Shatter an enemy using Cold damage (e.g., Ice Strike). This triggers Herald of Ice, which then Shocks, initiating the chain reaction. Prioritizing Herald of Ice is recommended because Freeze is easier to inflict than Shock, and Herald of Thunder's lightning bolts have better range.
