POE2 Currency patch 0.3 has opened the floodgates to some of the wildest builds we've seen so far, and none stand out more than the Infernalist abusing Demon Form, Pyro Pact, and Recoup mechanics. This setup is not theorycraft fluff—it's a fully functional monster capable of melting bosses, sustaining through near-lethal damage, and dominating maps with style. If you've been searching for the most insane Infernalist setup in PoE2, look no further.

Core Idea – Demon Form Meets Pyro Pact

At the center of the setup is Pyro Pact, a spell that allows you to trade chunks of your own life for devastating fire explosions. Normally, this would be extremely dangerous, as self-damage mechanics can quickly spiral out of control. But when you pair it with the Infernalist's Demon Form, it becomes a devastating loop.

Demon Form grants:

Huge more fire damage multipliers

Increased area of effect, making every explosion cover the screen

Resistance bonuses, including notable chaos resistance

Burning synergy that amplifies ignite damage

When combined with Pyro Pact, Demon Form doesn't just offset the drawback—it actively makes the self-damage an engine for power.

The Recoup Trick – Self-Damage Becomes Fuel

What makes this build "insane" is how recoup mechanics convert your self-inflicted damage into sustainability. Recoup allows you to recover a percentage of the damage you've taken over the last few seconds as life or mana. Since Pyro Pact constantly damages you, you essentially create a renewable recovery loop.

Key recoup sources in patch 0.3 include:

Infernalist passives granting fire damage taken recouped as life

Gear mods like rings and amulets with % of damage taken recouped as mana

Support gems and recovery passives that accelerate the recoup rate

Instead of draining yourself dry, Pyro Pact becomes a resource engine that lets you spam firebombs endlessly.

Damage Output – Explosions on Explosions

The offensive side of this setup is nothing short of absurd. Every cast of Pyro Pact produces a screen-wide detonation, and the Infernalist's scaling takes it even further. The key damage layers include:

Fire and chaos multipliers from Demon Form

Ignite scaling, which stacks heavy burning damage on top of the initial blast

Increased AoE, ensuring nothing survives in mapping scenarios

Bosses melt because the self-damage loop allows you to cast rapidly while maintaining sustain, stacking ignites and detonations until their life bars vanish. Mapping, on the other hand, feels like chain reactions of fiery nukes clearing entire screens at once.

Defensive Strength – Surprisingly Durable

At first glance, sacrificing life repeatedly sounds suicidal, but with recoup, this setup is remarkably tanky. When 70–80% of your self-damage is refunded as life and mana recovery, you essentially maintain both resources at near full capacity. Add in Demon Form's innate resistances and reduced damage taken from burning enemies, and you've got a surprisingly durable caster.

This means you don't just deal insane damage—you can also stand your ground in high-tier content without feeling like a glass cannon.

How to Build It

To replicate this setup, follow these priorities:

Skill Gems:Pyro Pact + Ignite Proliferation + Fire Penetration for offense.

Transformation:Demon Form supported with duration and cost reduction gems.

Gear:Prioritize items with recoup mods for both life and mana.

Passive Tree:Path into fire/chaos multipliers, ignite chance, and recovery scaling.

Playstyle:Enter Demon Form, spam Pyro Pact continuously, and let recoup sustain you while everything burns.

The Infernalist Demon Form Pyro Pact Recoup build is one of the most satisfying and overpowered archetypes in buy Path of Exile 2 Currency current 0.3 patch. What looks like a dangerous self-harming playstyle quickly becomes a self-sustaining engine of destruction once recoup mechanics are in place. It's not bait—this is truly one of the most insane setups available right now.

If you're looking for a build that combines explosive screen-clearing, boss-melting damage, and rock-solid sustain, this is the Infernalist you want to play in 0.3.
