If you’ve been exploring PoE 2 Boosting ’s deep character-building system, you’ve likely noticed how dramatically the reworked classes and skill interactions reshape build identity. Among all the changes, no archetype feels more explosive—literally—than the newly reimagined Infernalist subclass of the Witch. In this guide, we’ll dive into an 800-word breakdown of a practical, league-viable Infernalist Summoner who blends fire damage, chaos scaling, corpse consumption, and minion utility into a devastating engine of destruction.

Why Infernalist?

Infernalist specializes in burning the world down through corpse-powered detonations and damage-over-time effects. Unlike traditional Necromancers that rely on a permanent undead army, Infernalists generate expendable minions—volatile, short-life tools that become fuel for gigantic AoE explosions. The subclass rewards aggressive gameplay, consistent corpse creation, and creative layering of fire and chaos sources.

The key strengths of the Infernalist Summoner include:

• High screen-wide clear through chaining explosions

• Fire and chaos hybrid scaling for flexible gearing

• Minion utility without dependency on survivability

• Excellent boss damage from stacked DoTs

• Very strong synergy with revamped support gems

The main drawback is that the build is not a pure summoner; you must actively create and destroy minions and corpses. Players who love explosive, strategic gameplay will feel right at home.

Core Skill Setup

The backbone of the build relies on this three-part skill loop:

1. Summon Fiend / Summon Bone Construct (or any fast-dying minion):
   You only need one button to generate minions rapidly. Faster casting means faster explosions.

2. Infernal Burst (Corpse Explosion Spell):
   This is the build’s signature mechanic. Consuming a corpse triggers a fire/chaos detonation whose damage scales with corpse life, your spell power, and fire/chaos multipliers.

3. Chaosfire Veil (DoT Aura / Ground Effect):
   A hybrid aura that burns enemies with both fire and chaos over time. When paired with explosions, enemies constantly take overlapping damage instances.

Support Gems

POE2’s support gems scale more linearly and buff individual skill identities. For the Infernalist, the most impactful are:

• Elemental Amplification – boosts fire DoT and explosion scaling

• Overcast Support – slower but stronger explosions, ideal for bossing

• Destructive Release – pushes AoE radius during corpse detonation

• Withering Focus – stacks chaos debuffs enabling hybrid scaling

• Minion Instability (Passive Scaling / Keystone Interaction) – increases corpse life, dramatically buffing explosion damage

These supports create a snowball effect: larger corpses → bigger explosions → stronger DoTs.

Gear Priorities

Early game:

• +Spell Damage

• Fire Damage over Time Multiplier

• Chaos Damage Multiplier

• Minion Life (yes, this buffs your explosions!)

Mid game:

• Fire/Chaos penetration on weapons

• Added Fire to Spells

• Cast speed for smoother summoning

• Life/Resists for basic survivability

Late game:

• Unique items that boost corpse life or grant powerful DoT auras

• Chaos conversion items for fire → chaos hybridization

• Ignite/Corrosion stacking gear

• Jewels with double damage over time modifiers

Your best weapon is typically a wand or staff with double multipliers and a modifier that increases “Damage from Consumed Corpses.”

Ascendancy Highlights

Infernalist excels at:

• Corpse Empowerment: increases corpse life significantly

• Profane Flames: adds chaos conversion and penetration

• Ashen Dominion: boosts ignite and burning damage

• Volatile Legion: spawns temporary minions automatically

These choices create a constant loop of corpse generation, explosion triggers, and damage layering.

Defensive Layers

You’re not tanky by default, so defense comes from:

• Bone Shield Minions (temporary tanks)

• Chaosfire Veil’s small defensive component

• Energy Shield stacking on Witch gear

• Fire/Chaos resistance overcap to avoid spike deaths

Play smart: step behind minions, drop ground effects, and let explosions do the work.

Endgame Performance

Mapping:
The build absolutely melts packs. One corpse explosion chains into the next, clearing entire screens.

Bossing:
Sustained DoTs from chaosfire auras and repeated corpse consumption create consistent damage, ideal for bosses with extended phases.

Conclusion

The Witch Infernalist Summoner stands out as a flexible, visually spectacular build that blends the best of fire DoTs, chaos scaling, and minion utility. It’s fast, dramatic, and responsive—perfect for players who want control over destructive magic without managing fragile permanent minions.

If you enjoy hybrid spellcasters, detonation strategies, and dark summoner aesthetics, the Infernalist Summoner is one of PoE 2 Boosting service ’s most satisfying choices.
