In Diablo 4 Season 8, Belial stands out as one of the most formidable Lair Bosses you will encounter. To triumph over this boss, players should utilize builds that not only offer substantial single-target damage output but also enhance mobility and survivability during the fight’s two distinct phases. Whether your goal is to farm Distilled Fear, collect Resplendent Sparks, or chase after high-tier loot, employing top-tier builds tailored for efficiency is essential.
Top Builds to Conquer Belial in Diablo 4 Season 8
Rogue: Twisting Blades Shadow Clone
This variant of the Rogue class is recognized as the leading boss killer for this season. It capitalizes on high burst damage due to its mechanics, which not only returns hits but also benefits from the Shadow Clone’s ability to duplicate attacks.

Timing the use of Shadow Clone right before entering Belial’s second phase can deplete his remaining health swiftly.
Sorcerer: Lightning Spear Auto-Crit Build
The Lightning Spear build is engineered for relentless auto-casting along with crit stacking, leveraging Unstable Currents for significant burst damage opportunities.
