The Infernalist Witch has long stood as one of Path of Exile 2’s most iconic and fiery archetypes. With Patch, the class receives its most transformative update yet – a fully realized Demon Form. Unlike its earlier versions, the new iteration allows players to wield weapons while transformed, opening a vast range of new build synergies. The result is a powerhouse that balances raw magical destruction with nimble, aggressive combat flow.
This guide dives into the Lightning Demon Form Infernalist, a league-starter build that begins with a steady Contagion + Essence Drain core and transitions into a Ball Lightning + Lightning Warp monster around level 75. Whether you’re an SSF (Solo Self-Found) grinder or a Trade League power player, this build delivers spectacle, speed, and strong scaling potential.

Build Progression (League Starter Path)
The Lightning Infernalist is built for smooth progression from level 1 to the mid-70s without needing rare gear. Early on, you’ll lean on Contagion, Unearth, and Skeleton Warriors for survivability and mapping. As you transition into midgame, Essence Drain boosts your single-target power. Finally, around level 75, your build transforms-literally-into a Lightning Warp and Ball Lightning Demon Form playstyle that obliterates packs with style.
