The Relentless Heart is a Barbarian-exclusive Unique Chest Armor in Diablo 4 introduced with the Lord of Hatred expansion, built entirely around Hammer of the Ancients single-target damage. Each consecutive hit of Hammer of the Ancients on the same target deals 22.5–30% increased damage, stacking up to 3 times for a maximum of 67.5–90% increased damage. The stacks build rapidly in normal combat because both your own Hammer casts and the HotA-Ancients summoned through Arreat’s Bearing apply stacks independently — meaning stacks ramp to maximum almost immediately and stay there throughout any sustained encounter. Its inscription reads: “Though he was stuck with a dozen arrows, the barbarian charged Rakkis’ lines and swept away any who stood before him. The more he bled, the more ferocious were his blows.” Maxroll’s Hammer of the Ancients Barbarian guide lists The Relentless Heart as the dedicated chest armor for the build in Season 13. Our service delivers it directly via in-game trade so you can start building around it immediately.

Frequently Asked Questions (FAQ)

Understanding The Relentless Heart
The Relentless Heart carries its inscription from the Chronicles of Rakkis — a barbarian so driven by battle fury that a dozen arrows could not stop his charge. The more he bled, the harder he struck. This is the chest armor’s entire design philosophy translated directly into a game mechanic: consecutive Hammer of the Ancients hits on the same target escalate in power with each blow, rewarding the player who commits fully to hammering one target relentlessly rather than spreading attacks across multiple enemies.
Hammer of the Ancients has historically been one of the Barbarian’s strongest skills but has struggled with single-target boss damage compared to its AoE performance. The Relentless Heart directly addresses this by converting sustained boss focus into a damage multiplier that scales over the first few hits and stays elevated for the rest of the encounter. At maximum stacks a 30% roll provides 90% increased damage — a substantial multiplicative bonus that compounds with Critical Strike Damage, Berserking amplification from Emblem of Staalbreak, Overpower from Banished Lord’s Talisman, and every other damage source simultaneously.
The interaction with Arreat’s Bearing is what makes stack maintenance trivial in practice. Arreat’s Bearing summons additional Ancients who cast Hammer of the Ancients independently throughout the fight. Each of these Ancestral HotA casts applies stacks to whatever target they hit — meaning even during the Barbarian player’s own brief animation recoveries between casts, the summoned Ancients continue applying stacks. Maxroll’s HotA guide describes this as making the ramp a non-issue, because the combined cast frequency of player and Ancients keeps all three stacks applied essentially continuously against any sustained target.
Why Buy The Relentless Heart
Farming specific Uniques in Diablo 4 requires running targeted boss encounters repeatedly with summoning materials accumulated through endgame activity. The Beast in the Ice is the primary source for The Relentless Heart — requiring Nightmare Dungeon Lair Keys that take consistent endgame farming to accumulate. The randomized affix system in Lord of Hatred means finding the right chest with optimal Greater Affix configuration adds further RNG on top of the base drop. Our delivery service gets The Relentless Heart to you immediately via in-game trade, letting you start stacking consecutive HotA hits for up to 90% increased damage right away without grinding endgame content hoping for the right chest to drop.
Great experience from start to finish. They helped me with my Diablo 2 request exactly as promised. Fast delivery, good communication, and everything was handled professionally. Will definitely use Instant Carry again.
