Path of Exile 2 has no shortage of ambitious spell builds, but every once in a while a setup emerges that doesn’t just scale damage—it rewrites the rules of how resources, ailments, and spellcasting interact. The build outlined here is exactly that: a triple-infusion spell engine built around Spark, Arc, and Comet, fueled by elemental ailments, POE 2 Orbs, and an endlessly looping feedback system that turns once-mediocre mechanics into something borderline absurd.

This article breaks down the build in the same order any serious player should evaluate it: first the engine that makes it work, then the gameplay loop, and finally the requirements and cost considerations that determine whether it fits your character and your budget.

Understanding the Core Concept: Why This Build Works

At the heart of this build is a single defining interaction: Pinnacle of Power, enabled by Adonia’s Ego Siphoning Wand. This buff fundamentally alters how elemental damage behaves by allowing all elemental damage types to contribute simultaneously to ignite, shock, and freeze.

Normally, elemental ailments are restricted by damage type—fire ignites, lightning shocks, cold freezes. Pinnacle of Power removes that limitation entirely. Once active, any elemental hit can apply all three ailments at once.

That single change unlocks the entire engine.

Suddenly, spells that were never intended to ignite or freeze now do so effortlessly. Mechanics that once required specialized scaling now trigger passively. Most importantly, systems like Cast on Elemental Ailment and Siphon Elements, which were previously niche or underwhelming, become absurdly powerful.

The Gameplay Loop: From Spark to Infinite Casting

Every successful Path of Exile 2 build lives or dies by its gameplay loop. This one is deceptively simple on the surface, but under the hood it’s a carefully layered machine.

Step One: Cold-Infused Spark

The loop begins with Spark, infused with cold. Spark is the foundation spell—the initiator. With Pinnacle of Power active, each Spark hit now:

Ignites the target

Shocks the target

Freezes the target

That alone would be strong, but the real payoff comes from what those ailments enable.

Because Spark is now applying multiple elemental ailments simultaneously, it feeds directly into Cast on Elemental Ailment, a mechanic that historically struggled to justify its cost. Under Pinnacle of Power, it becomes one of the strongest triggers in the game.

Generating Energy: Feeding the Lightning Infusion

Each elemental ailment applied by Spark contributes energy toward your Lightning Infusion spender, which in this build is Arc.

Arc serves two primary purposes:

Area-of-effect clearing

Scaling shock magnitude and critical energy

Supported by Science, Temper, Commissary, and Overcharge, Arc becomes a devastating screen-clearing tool. Its chained lightning hits multiple enemies, applying massive shock values thanks to Pinnacle of Power’s ailment scaling.

But Arc isn’t just about clear speed. Every shock it applies feeds back into your resource engine, generating additional critical energy that sets up the next layer of the loop.

Cast on Critical: The Single-Target Solution

Where Spark and Arc dominate mapping and crowd control, Spell Cascade Comet handles elites and bosses.

This is your Fire Infusion spender, triggered via Cast on Critical. Thanks to the synergy between Spark and Arc, critical energy generation is constant, allowing Comet to rain down repeatedly during sustained encounters.

Comet benefits enormously from Pinnacle of Power:

Its hits ignite, shock, and freeze

Each ailment feeds Siphon Elements

Each trigger generates additional infusions

The result is single-target damage that scales not just with raw numbers, but with how efficiently the engine keeps running. Bosses don’t just take damage—they become fuel.

Siphon Elements and the Birth of Infinite Infusions

This is where the build crosses the line from “strong” into “engine-driven.”

Because all three spells—Spark, Arc, and Comet—apply all three elemental ailments, every hit interacts with Siphon Elements. Instead of generating a limited trickle of infusions, the build produces them endlessly.

Each infusion you pick up feeds into Refracted Infusion, which grants an additional elemental infusion. In practical terms, this doubles your infusion generation.

But the loop doesn’t stop there.

Mana Remnants: Solving the Resource Problem Forever

Infusions alone would be impressive, but the real magic happens when mana enters the equation.

Whenever you critically strike an enemy affected by an elemental ailment—and remember, everything is affected—you generate a Mana Remnant.

Collecting a remnant restores 3% of your maximum mana. And because infusions themselves count as remnants, every pickup becomes a mana recovery event.

Now add Storm’s Recollection to the equation.

Storm’s Recollection causes any remnant you create to reappear three seconds after being collected. Combined with the build’s massive remnant pickup range, you can:

Move forward through a map

Leave remnants behind you

Automatically collect them again seconds later from long distances

Each re-collected remnant triggers Refracted Infusion again, doubling infusion generation again and restoring more mana.

The result is a feedback loop where:

Mana never runs out

Infusions are effectively infinite

Spellcasting never slows down

The Infinite Engine Explained Simply

When all components are active, the loop looks like this:

Cast Spark

Spark applies ignite, shock, and freeze

Elemental ailments trigger Cast on Elemental Ailment

Energy feeds Arc

Arc clears and generates critical energy

Critical hits trigger Comet

All spells apply ailments

Ailments generate infusions via Siphon Elements

Infusions trigger Refracted Infusion

Infusions count as remnants

Remnants restore mana

Storm’s Recollection respawns remnants

Re-collected remnants double infusion and mana generation

Infinite triple-infused spellcasting continues

Once the engine is running, it sustains itself indefinitely.

Build Requirements: What You Need to Get Started

Naturally, a build this complex doesn’t come online at level 20. There are some firm requirements.

Minimum Level

Level 85 is required to fully support the passive allocations, spirit requirements, and gem setups that make the engine function smoothly.

Mandatory Unique Item

Adonia’s Ego Siphoning Wand

This item is non-negotiable. Without it, Pinnacle of Power doesn’t exist, and the entire build collapses.

Spirit Requirements and Gem Variations

Spirit management is one of the few tuning knobs in this build. Depending on your setup, you’ll need different spirit thresholds.

The two most common configurations are:

Efficient Inscriptions amulet allocation

Dialla’s Desire lineage gem in Cast on Critical

Each option changes how much spirit you need to sustain your triggers. The build documentation typically includes a spirit requirement table, allowing you to choose the configuration that best fits your available gear.

Scaling Power: Unique Item Priority

Beyond the wand, the build scales through a ranking of powerful unique items. These aren’t all mandatory, but each one pushes the engine closer to perfection by:

Increasing infusion generation

Improving remnant pickup range

Enhancing critical strike consistency

Amplifying elemental ailment effectiveness

Because the core engine already provides infinite mana and infusions, additional gear primarily improves efficiency rather than enabling functionality.

Final Thoughts: Is This Build for You?

This Path of Exile 2 build is not about simplicity—it’s about mastery. If you enjoy builds that:

Reward understanding over brute force

Turn obscure mechanics into core power sources

Scale through interaction rather than raw stats

Then this infinite infusion engine is one of the most satisfying setups currently possible.

It transforms Spark from a humble projectile into the ignition key of a self-sustaining spell reactor. It elevates Arc into a resource generator, not just a clearing tool. And it turns Comet into a relentless boss killer backed by endless mana and infinite infusions buy POE2 Currency.

If the engine itself excites you, the cost fits your budget, and you enjoy builds that feel almost unfair once mastered—this might be the most fun you’ll have casting spells in Path of Exile 2.
