Path of Exile 2 Build Con Lightning Warp Ability Movement Takes Some Getting Used To

This Comet Infernalist build relies on a Life on Recoup loop to sustain Demon Form and on a Cast on Elemental Ailment gem to trigger elemental-infused skills for automated spell casting.

As this build utilizes Demon Form, the build can continue to scale all the way up to the end game, as it can sustain Demon Flame stacks thanks to our sources of life recoup.

Build Notes


Understanding the Build Foundation

At its core, the build relies on Lightning Warp and Spellslinger to generate energy to trigger Cast on Elemental Ailment, allowing for repeated casting of the gem you socket into it.

This means that you can use different versions of the build by changing the skill you socket into Cast on Elemental Ailment and still retain its core function.

Map Modifiers to Avoid

The build sustains its spell casts by using a Life Recoup loop which can be started with Lightning Warp even before engaging in combat. This loop can be cast repeatedly to trigger Life Recoup and offset the life loss from Pyromantic Pact and Demon Flame.

As such, it is important to avoid Waystone modifiers that penalize the recovery of life and energy shield, as well as resistances, if possible, as they can interfere with our life recoup loop and render our casts unsustainable.

Calculating Life Recoup

To get an idea of how many stats you need to correctly sustain a life recoup loop, use the calculator provided by Hungryboots to determine if your current stats allow you to sustain the loop.

You can try running with less recovery by pausing between Thunder Warp casts before engaging enemies to activate your keystone passives, such as Pliable Flesh. That said, the calculator should give you a good idea of whether your current gear can comfortably handle the loop.

For an in-depth explanation on how to use the Life Recoup Calculator, you can refer to Hungryboots' explanation in this video (External Link to Youtube Video).

Weapons

We will get a dueling wand for Spellslinger to generate more energy. We will prioritize the Level to All Spells modifier rather than a specific element because this allows for flexible builds, letting you swap your skill gems without altering your gear.

If you're set on using just a single skill setup to cut costs, you can choose to use one with a specific element.

Chiming Staff will solely be used for the Sigil of Power buff, so getting too many modifiers, apart from spell levels and cast speed, isn't necessary.

List of Weapons

Armor and Accessories

We take as much as life and energy shield recoup on our gear as much as we can, as they are essential to make the build function, and allow our recoup loop to get going.

Naturally, capping out our resistance is just as important, most notably our fire resistance, as we rely on it more than other resistances due to Pyromantic Pact triggers.

Since this build relies heavily on life recoup, we will take the unique chest piece, Sacrosanctum, for additional life recoup and bonus energy shield recoup.

Runes and Soul Cores

Armor

We will use Thane Girt's Rune of Wildness to increase the number of projectiles in our Ball Lightning, allowing us to generate more energy for casting on elemental ailments.

The Soul Core of Puhuarte is used to reach the Fire resistance cap as quickly as possible, and can be paired with Greater Iron Runes to increase survivability once resistances are capped. You may utilzie other elemental runes instead of Soul Core of Tacati, depending on the elemental rolls on your gear.

Lastly, we will use Estazunti's Soul Core of Convalescence and socket it into our helmet for increased life recovery.

Our life recoup loup will allows us to sustain multiple spell casts, but it will cost our life total to fluctuate wildly as Pyromantic Pact on running out of mana, which can be quickly be regenerated by our life recoup.

This leaves us vulnerable to bleeding and poison because their damage bypasses Energy Shield. To counteract this, we will take the Antidote and Staunching charms, which will prevent us from taking poison and bleeding damage. This will allow us to continue our cast loops without endangering ourselves.

Lastly, we will use a Thawing Charm to avoid freezing and maintain mobility during runs.

Comet Rain Infernalist Skills

All Active and Persistent Skills

※ The Support Gems' priority are arranged in a descending order. The first one being the most important and the last being the least crucial.

Comet
Arc
Fireball

Gem placement matters, so for the Comet variant, socket Living Bomb before Comet to ensure Comet activations are fire-infused.

This build revolves around triggering Cast on Elemental Ailment to trigger additional automated spell casts, and is designed in a way that you can freely change some of the support gems to use the skill that you want.

Spellslinger will strictly be used for energy generation and Lightning Warp triggers, so Ball Lightning and Multishot will be socketed here, as well as Boundless and Energy and Retention.

For other build variants that don't utilize Comet, Ricochet benefits this build a lot due to how often Cast on Elemental Ailment triggers, so it will be taken for variants that utilize skill projectiles.

※ Legend: Red = Weapon Set I Green = Weapon Set 2

The build utilizes the Demon Form Ascendancy skill, so we will be taking Demonic Possession and Mastered Darkness to use Demon Form and remove the Demon Flame Stacks limit.

We will be taking utilizing elemental ailments to trigger our elemental spells for damage, so we will take passives such as Echoing Flames, Electric Amplification, and Stripped Defences.

We will be relying on Life Recoup to sustain Demon Form as well as our spell casts, so we will be taking key nodes such as Pliable Flesh, Loose Flesh, and Glazed Flesh.

Comet Rain Infernalist Playstyle

Mobbing Rotation

  2. Cast Ball Lightning in the direction of targets.
  3. Cast Lightning Warp on your Ball Lightning projectiles to trigger your cast on elemental ailment socketed spell.

Bossing Rotation

You will be utilizing your core rotation for bosses and tanky elites, with buffs and debuffs woven in for more damage.

  1. Cast Demon Form to start gaining stacks.
  2. Cast Sigil of Power for the buff.
  3. Use Elemental Weakness to lower enemy resistances.
  4. Use Entagle for additional Shock triggers.
  5. Cast Frost Bomb for the Elemental Exposure Debuff.
  6. Cast Ball Lightning in the direction of targets.
  7. Cast Lightning Warp on your Ball Lightning projectiles to trigger your cast on elemental ailment socketed spell.
