I found that picking the right passives is vital to make this build smooth and survivable. My key choices include Endless Fury for sustained Fury generation, Imposing Presence to reduce enemy damage and boost your own, Belligerence and Prolific Fury to improve attack and resource generation, and Swiftness for mobility Diablo 4 Items.
On the defense side, Aggressive Resistance, Pit Fighter, Defensive Stance, and Thick Skin provide great durability. No Mercy and Heavy Hitter push your damage output by improving crit damage and overall effectiveness. I also like Duelist for critical chance boosts and Counteroffensive for added damage after blocking.
The Capstone skill Unconstrained fits perfectly with this build because you stay Berserk most of the time, don’t spend much Fury, and rarely switch weapons. It removes unnecessary constraints, letting you attack continuously with maximum efficiency. Combined, these passives emphasize strong Fury uptime, survivability, and raw damage—the perfect balance for fast, fun leveling Diablo 4 gold.
