Build Notes

Barrier Invocation Comparison

The 0.2.0 Patch for Path of Exile introduced a slew of nerfs, affecting the build directly. The nerfs to Barrier Invocation broke the interactions that the build previously relied on, effectively removing its viability.

The Pyromantic Pact ascension node is used to support this resource-intensive build to generate the resources necessary to cast spells. However, this build is not limited to the Infernalist ascendancy; other classes can adopt this build as long as they can generate the resources needed to trigger the spells.

Demon Form Stacks Limitation

Currently, the build is limited to using only 10 stacks of Demon Form. While this limits the potential damage output for the build, it is more than sufficient for mapping.

Mastered Darkness may be taken later as we improve the build and find other sources of sustain, so stay tuned!

Weapons

Since the build will be using the Demonic Possesion Ascendancy node to access Demon Form , this build will not be using any weapons.

This gives us +6 to all spell levels, which would otherwise be quite expensive to obtain since it requires the maximum roll for a weapon and an offhand.
List of Weapons

Armor

When setting up the build, maximize Fire Resistance first over the other elements, as we need to max it out as soon as possible to mitigate damage taken from Pyromantic Pact. Chaos Resistance comes second, and the other resistances should follow, but wouldn't require much investment thanks to Altered Flesh.

List of Armors

Accessories

Annointed Amulet

To ensure 100% uptime on Life Flask Usage, the Heavy Drinker passive needs to be annointed in the amulet. Since this build is a Flask Usage intensive setup, this keystone passive is required for this build.

List of Amulets

Blackflame Amethyst Rings

Since the build revolves around triggering spells when targets are Ignited, getting two Blackflame Amethyst Rings for the Increased Ignite Magnitude is essential to this build.

The increased Ignite Magnitude from the ring increases the energy it generates when we Ignite targets, allowing us to reach the energy required to trigger Cast on Ignite much faster.

List of Rings

Runes and Soul Cores

Equipment Sockets
Armor

The Soul Core of Puhuarte can be used alongside Greater Desert Runes to reach the Fire resistance cap as quickly as possible, and can be replaced with Greater Iron Runes to increase survivability once resistances are capped.

Charms

Since we will be using the Oasis passive, the use of charms will be disabled.

CoI Demon Form Infernalist 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.

Skill Support Gems
Demon Form IconDemon Form
Cast on Ignite IconCast on Ignite
Cast on Ignite IconCast on Ignite
Cast on Ignite IconCast on Ignite
Flammability IconFlammability
Solar Orb IconSolar Orb
AlchemistAlchemist's Boon -
Overwhelming Presence IconOverwhelming Presence -

Solar Orb will be the primary skill used to procc Ignite on targets, so Overabundance is taken to be able to use the skill twice, effectively doubling the chances of triggering Ignite, which works well with Overwhelming Presence.

For the Cast on Ignite skill itself, Comet is used because it is the strongest non-channeling spell currently available on its own, though it can be substituted with another non-channeling spell such as Arc or Fireball.

CoI Demon Form Infernalist Passive Tree

Passive Tree Progression

Ascendancy Passive
Path of Exile 2 Cast on Ignite Demon Form Infernalist Node
Pyromantic Pact, Demonic Possesion, Beidat's Will
1. Loose Flesh and Echoing Flames 2. Energise and Careful Assassin
3. Hale Traveller and Cooked 4. Cautious Concoctions and Oasis

The Infernalist has a lot of Ascension nodes that make this build work. Beidat's Will allows the build to equip multiple Cast on Ignite skill gems and other notable passives that require Spirit. For spellcasting, Pyromantic Pact will be our main source of Energy generation instead of Mana.

For our passives, we will use a mix of spell damage, Life Recoup to sustain Demon Form, and improvements to our flask.

CoI Demon Form Infernalist Playstyle

Skill Rotation

※ Press on what type you are fighting for a more detailed explanation on the playstyle and skill rotation.

Type Skill Rotation
Standard Rotation
Demon Form Icon Flammability Icon Solar Orb Icon Cast on Ignite Icon

Standard Rotation

The rotation is very simple and would apply to all combat encounters.

  • Cast Demon Form to start gaining stacks
  • Cast Flammability on your target to increase the energy generated from ignite proccs
  • Cast Solar Orb twice to trigger your socketed Cast on Ignite spells

Just remember to keep an eye on your energy shield and use Flasks when necessary. Since we will be using Eternal Youth, just use Flasks as needed to restore lost Energy Shield.
