Path of Exile 2 Patch 0.5.0 Infernalist Demon Form Witch Explained | The High Risk High Reward Build with Infinite Damage Scaling
Category: Path Of Exile 2 Posted: Jul 30, 2026 Views: 9
Infernalist is one of the coolest Ascendancy classes in Path of Exile 2. It allows you to command a demonic army or transform yourself into a fire-wielding demon.
However, in PoE 2 Patch 0.5.0, Infernalist is not a particularly popular choice, and the pick rate of Demon Form is even lower. The reason is that this is not an easy build to control. It is extremely dangerous, and a single mistake can cause you to die instantly, leading to a frustrating experience. But at the same time, it is incredibly powerful. As long as you can stay alive, it can melt through almost everything.

Demon Form Witch Mechanics
Demon Form
First, let's talk about the core skill, Demon Form. Its effect is that every second while transformed, you gain one stack of Demonflame state. Each stack of Demonflame grants 3% more Spell Damage. This is an independent damage multiplier, which can greatly increase your overall damage.
In its default state, Demon Form has a maximum limit of 10 Demonflame stacks, meaning it provides 30% more Spell Damage. This may not sound like much, but if you also choose Mastered Darkness, you can remove this limitation and stack Demonflame infinitely.
This means that with 200 stacks of Demonflame, you can easily gain 600% more Spell Damage. Without relying on extreme scaling methods, this level of damage amplification is almost impossible to reach through any other method in the game. In theory, your damage can continue scaling infinitely.
Demonflame
However, this power comes with a serious cost. Every stack of Demonflame causes you to lose life, and the higher the number of stacks, the faster your life drains. If you reach 200 Demonflame stacks without any form of life recovery, you will kill yourself within only a few seconds because of this drawback.
Keep in mind that this life loss cannot be reduced by any defensive mechanic, including Armour, Evasion, Block, Deflection, or Energy Shield. Since you cannot prevent the life drain itself, you must recover life faster than Demonflame can take it away.
Pyromantic Pact
One of the solutions to this problem is Pyromantic Pact passive. It removes your Mana pool completely and replaces it with Infernal Flame.
Unlike normal Mana costs, using skills will fill your Infernal Flame meter. When Infernal Flame bar becomes completely full, you immediately take Fire Damage equal to your maximum Life plus your maximum Energy Shield.
This sounds like a drawback, but everything changes when combined with Recoup mechanic. Recoup collects a portion of Fire Damage you take and converts it into Life Recovery over the following few seconds.
However, this is still not enough. You also need Sacrosanctum Corvus Mantle. This chest armour itself provides 20% of Damage Recouped as Life. It can also gain a Recoup modifier through corruption, further increasing your recovery. In addition, Damage Recouped as Life effect can also recover Energy Shield.
With this setup, as long as you continuously cast skills and fill Infernal Flame bar, the overflow damage will ignite you. Your 75% Fire Resistance reduces three quarters of that damage, while the remaining portion becomes a Life Recoup effect that offsets Demonflame's drawback. Sacrosanctum also restores Energy Shield, helping prevent sudden deaths when you are hit by enemies.
Maximum Mana
This recovery cycle is not easy to build, and there are several traps you need to avoid. One important factor is that Infernal Flame's capacity equals twice your maximum Mana. If your maximum Mana is too high, filling Infernal Flame bar becomes extremely difficult, which breaks the entire cycle.
You need to keep your maximum Mana under control, and ideally it should stay below 700.
Skill Cost
After solving the mana issue, the next problem is how to increase Mana consumption. The key point is that this build does not aim for low costs. Instead, it focuses on extremely high skill costs.
The higher the skill cost, the faster you fill Infernal Flame bar, allowing you to trigger Recoup mechanic more frequently and recover Life.
You can link Despair with Focused Curse Support Gem, which comes with a 120% Skill Cost Multiplier and greatly increases the cost of each cast.
To make Infernal Flame bar smaller and easier to fill, you also have several other methods to reduce its required capacity.
- Heroic Tragedy Timeless Jewel: Converts important passive nodes within its radius into Knightly Tenets, causing Intelligence to no longer provide base Mana and instead granting Evasion Rating.
- Megalomaniac Diamond: Grants Vulgar Methods, which provides a 10% reduction to maximum Mana.
- Melding (Passive): Provides another 10% reduction to maximum Mana.
- Overzealous (Notable Passive): Grants 16% increased Cast Speed and 15% increased Skill Cost.
With all of these combined, a single cast of Despair can almost fill the entire Infernal Flame bar. However, this might require you to invest in these items and unique gems. You can join PoE 1 & 2 currency giveaways in IGGM Facebook Group. If you win, The mirrors can be enough to completely revamp your build.

Core Skills
Doedre's Undoing also needs to be linked with Despair, completely changing how this skill works. Instead of being a normal curse that you directly apply to enemies, it turns Despair into a Cursed Ground effect placed on the ground. Any enemy entering the area will automatically become cursed. You can only have two active cursed areas at the same time.
The limit of only two areas may seem like a weakness, but it is actually the foundation that allows the entire build to function. When linked with Spell Cascade Support, each cast creates three cursed areas.
Whenever you cast a new Despair, the newest cursed area replaces the oldest one. This triggers the effect of Impending Doom Support, which grants Doom Blast. Doom Blast instantly deals Chaos Damage when the curse supported by it expires.
Every new Despair cast replaces an existing cursed area. Interestingly, when a cursed area is overwritten by a new one, it counts as the old curse ending, which activates Impending Doom and creates a massive Chaos explosion.
Doedre's Undoing also spawns Witchtoads on the ground after you cast Despair. They jump toward the nearest enemy and explode on contact, requiring no additional actions from you.
Trickster's Shard is also linked with Despair. It creates up to four clones of yourself, and they repeatedly cast Despair with 50% less damage. This allows you to see your entire screen filled with explosions.
What Should You Pay Attention To?
This build feels extremely satisfying to play, but that experience depends entirely on constant casting. Even when there are no enemies nearby, you still need to keep casting. Otherwise, Demonflame's effect will eventually catch up with you and kill you.
You also need to be extremely careful with maps that have modifiers such as "Players have less Life Recovery" and "Less Cooldown Recovery Speed." These maps are basically forbidden areas for this build because your recovery speed will not be able to keep up, causing you to die.
Demon Form Witch is not suitable for beginners or players who simply want to press a single button and zone out. You need a clear understanding of your actions and capabilities to effectively manage the effects of Demonflame.
