Path of Exile 2: Lightning Demon Form Infernalist Build Guide (Patch 0.3.0)

The Infernalist Witch has long been one of the most iconic archetypes in Path of Exile 2, and Path of Exile 2 Currency with Patch 0.3.0, the class has received one of its most exciting updates yet - the introduction of a fully realized Demon Form. Unlike earlier versions, the new Demon Form now allows players to wield weapons while transformed, opening the door to unprecedented build versatility and synergy.

In this guide, we'll cover everything you need to know about the Lightning Demon Form Infernalist - a smooth and powerful league-starter build that begins with a Chaos DoT foundation before transitioning into a Ball Lightning and Lightning Warp powerhouse. Whether you're new to PoE2 or a returning exile looking for something fast, flashy, and scalable, this Infernalist build is an incredible way to begin your next journey.

Why Choose the Lightning Demon Form Infernalist?

This build shines because of its unique hybrid approach - blending Chaos-based spells for early leveling with explosive Lightning abilities in the late game. It's also one of the most visually impressive builds in Path of Exile 2, thanks to the vivid effects of Ball Lightning and the dramatic Demon Form animations.

If you're playing in Trade League, you can easily buy POE2 Items or buy POE2 Currency to optimize faster, but even in SSF, this build scales efficiently through clever gear and passive tree choices.

Build Progression (League Starter)
