Path of Exile 2 Best Infernalist Build: Infinite Comets, Massive DPS & Runic Ward Explained

In Path of Exile 2 Patch 0.5.4, there's a build for Infernalist that not only doesn't consume Mana but also deals high damage. This article details this build, including its core mechanics and how to improve survivability and damage output.

Among the many builds in Path of Exile 2 Patch 0.5.4, one idea has consistently fascinated players: how to break through limitations of the game's resource system to achieve near-infinite skill casting?

In fact, a recently discovered build perfectly embodies this pursuit - a build specifically for Infernalist class. This build not only allows for the unlimited casting of powerful spells with high damage but also boasts decent defensive capabilities.

Next, I will introduce this build in detail.

Path of Exile 2 Best Infernalist Build: Infinite Comets, Massive DPS & Runic Ward Explained

Core Mechanics

This build utilizes Infernalist class's Ascendancy passive skill, Pyromantic Pact, to convert the resource consumed by casting spells from Mana into a special resource called Infernal Flame, thus making the powerful spell Comet, which normally requires a large amount of mana, "almost free".

However, free is never without a price. When casting speed reaches a certain level, Infernal Flame will rapidly fill up. Once the threshold is exceeded, the character will suffer Fire Damage based on the sum of Life and Energy Shield.

This constitutes a classic high-risk, high-reward scenario: either become a mobile turret capable of endless casting, or be consumed by your own flames.

Therefore, to practically utilize this build, a key challenge must be solved: how to cast spells frantically without burning yourself to death?

Improving Survivability

To address the survival challenge posed by this build's core mechanics, a viable solution is to introduce a defensive layer from PoE 2's Expedition mechanics - Runic Ward.

Runic Ward operates in the opposite way to the traditional Energy Shield. Energy Shield precedes Life, taking priority in damage absorption; while Runic Ward follows Life, serving as "last line of defense."

Specifically, when a single instance of damage is enough to reduce Life to zero, Runic Ward absorbs the remaining damage, allowing the character to survive with 1 point of Life.

Based on this mechanism, this build adopts an extreme strategy: actively lowering Life and investing all defensive resources into Runic Ward.

In this way, Fire Damage from each Pyromantic Pact trigger is absorbed by a massive amount of Runic Ward, allowing the character to continuously cast spells without dying instantly.

It's worth noting that self-damage caused by Pyromantic Pact is considered a "Hit" by POE 2 system, meaning it can be affected by various damage reduction mechanisms.

Therefore, if you don't want to use Runic Ward, you can also utilize the affix effect of the Kalandra's Touch copy ring to improve survivability.

Increasing Comet Count

Now that you no longer need to worry about burning yourself to death, you can confidently increase the number of Comets and increase damage.

You can use Cast on Elemental Ailment in Meta Gems of POE 2 Patch 0.5.4 as the core engine.

The mechanism works as follows: the player first casts a high-frequency, low-cost trigger skill - Spark is recommended here. When this skill inflicts Elemental Ailment status on an enemy, Cast on Elemental Ailment accumulates energy, automatically releasing Comet it assists upon reaching full charge.

To maximize the number of Comets using this mechanism, the key is to reliably and quickly generate Elemental Ailment status.

Fortunately, another Infernalist Ascendancy passive skill, Bringer of Flame, plays a crucial role here.

This skill allows all types of damage dealt by the player and their summons (not limited to fire damage) to contribute to the chance and effect of Ignite.

This means that lightning damage from Spark and chilling damage from Frost Bomb can help trigger Ignite, thus charging Cast on Elemental Ailment more frequently.

Combined with Elemental Equilibrium's conversion effect on Infusion Remnants, the character becomes a self-reinforcing status ailment generator, producing a large number of Comets that deal high damage over a wide area.

Further Damage Increase

Once you reach this stage, with unlimited casting resources and a large number of Comets, if you still feel the damage output is insufficient, this build can further increase damage.

In the previous step, Spark, as the trigger skill, directly determines the recharge speed of Cast on Elemental Ailment.

Therefore, by increasing the damage of the trigger skill Spark, you can increase the recharge speed, thus releasing more Comets and dealing higher damage.

POE 2 player who shared this build stated that his Spark DPS reaches 446,000 in normal state and exceeds 718,000 in better state, and suggested that other players at least increase DPS displayed on the trigger skill panel to 100,000.

So, how do you increase the panel DPS? Unsurprisingly, such astonishing damage figures stem from a significant investment in Keystone Passive and gear.

For example, a specific Timeless Jewel paired with From Nothing Diamond can almost double Spark's displayed DPS.

Furthermore, you can focus your Rare Jewels on increasing critical strike chance. If you can achieve a critical strike chance of 60% or higher for Spark, your critical strike damage bonus will reach 1500% or more, greatly increasing the overall build's damage.

Of course, this pursuit of maximum damage comes at a high cost. This build is extremely expensive, requiring a large amount of Currency.

However, the core mechanics of this build are not complex, meaning its floor is extremely high. Its high cost primarily stems from the top-tier gear and items needed to push damage to even greater levels.
