How Boss Powers Work: The Basics

Before we dive into the tier list and build suggestions, it’s essential to understand how Boss Powers function in Diablo IV. Each Boss Power consists of a Main Effect and one or more Modifier Effects:

Main Effect: The primary function of the Boss Power. It has a strong base impact on your character’s abilities, often modifying damage types, damage over time effects, or adding new skills.

Modifier Effects: These enhance or modify the Main Effect in unique ways, making the Boss Power adaptable to different playstyles. Players can equip up to three Modifier Effects, allowing for a high degree of customization in builds.

Scaling and Multipliers: Boss Powers are scalable and can level up from rank 1 to rank 20. At higher ranks, the effects become significantly stronger. For instance, at rank 1, Reaper’s Disruption grants a 1.05x vulnerable multiplier and a 10% multiplicative vulnerable damage bonus, but as the power levels up, the scaling improves, offering even higher damage potential.

Boss Powers offer exciting new ways to customize builds in Season 8. The introduction of these powers allows for synergy with existing skills and abilities, unlocking new avenues of high-damage output, enhanced survivability, and versatility across all classes.
