Season 9 of Diablo 4 introduces the "Big Bonk," a Barbarian build focused on the explosive power of Mighty Throw, combined with Hammer of the Ancients and precise timing to annihilate bosses in a single, devastating strike. Like many top-tier Diablo 4 Items builds, its effectiveness relies on both execution and gear synergy, transforming carefully selected legendary items into a one-shot powerhouse.

This build aims to deliver a massive nuke using a two-handed bludgeoning mace. The combination relies on activating Mighty Throw immediately after Hammer of the Ancients lands, resulting in extraordinary burst damage — often reaching 20–30 trillion per hit. Overpower mechanics and cooldown timing are crucial: both Mighty Throw and Hammer of the Ancients must hit in perfect synchronization for multiplier stacking.

The Bane of Ahjad-Den Gloves are central to the build, significantly enhancing Mighty Throw every 12 seconds. The Harlequin Crest (Shako) increases skill ranks and reduces cooldowns, aiding in maintaining the tight rotation. The Shroud of False Death is a top-tier chest armor that offers defensive and resource advantages.

Tibault’s Will, the Elder Mace of Delayed Extinction, and the Boots of Metamorphosis further enhance damage and utility. Additionally, a two-handed bludgeoning mace is essential to synergize with passive multipliers such as Wallop and Crusher glyph.

Wrath of the Berserker provides buffs and resource generation. Ground Stomp stuns enemies and activates Earthquake for multipliers. War Cry and Rallying Cry offer buffs and Fury generation. Mighty Throw initiates the nuke, while Hammer of the Ancients is timed just before Mighty Throw lands to trigger Overpower multipliers.

The Big Bonk build is a high-skill, high-reward configuration that excels in solo boss fights and Pit level progression. It emphasizes precision — precise timing, expertly crafted gear, and flawless resource management. When executed correctly with the appropriate Diablo 4 S9 meta items , enemies can be eliminated in one astonishing blow.
