Season 10 brings a nostalgic yet terrifying face back to Diablo fans: Bartuc, the Warlord of Blood. This fearsome warrior has been reimagined as the new boss of the Infernal Hordes mode, and he’s not pulling any punches.
If you’ve played previous Diablo games, you might remember Bartuc as a bloodthirsty sorcerer-turned-demon who worshipped power above all else. In Season 10, he returns as a major boss in the reworked Infernal Hordes endgame u4gm Diablo 4 items.
Infernal Hordes now include Chaos Waves—sudden spikes in difficulty that throw tougher mobs at you. Survive these, and you’ll be rewarded with more Aether, plus a chance to challenge Bartuc himself.
The fight is intense. Bartuc uses a mix of magic and melee, summoning blood-themed abilities and draining your health if you’re not careful. The encounter is fast, chaotic, and rewarding—especially with the loot he drops Diablo 4 gold.
Defeating Bartuc will give you a ton of Aether and a higher chance at Chaos Armor and top-tier gear. If you’re playing seasonal content seriously, farming him will become part of your grind.
