Season 10: Season of Infernal Chaos introduced new features to Diablo 4, and one of them includes changes to The Infernal Hordes, which includes the addition of a new boss.
Bartuc, Lord of Chaos, can now be challenged in The Infernal Hordes, but this requires that you progress efficiently throughout the waves during the activity.
By defeating the Lord of Chaos, you will be able to obtain rare loot and may even use what remains of your Burning Aether for additional rewards.
Bartuc, Lord of Chaos Location
Similar to the Fell Council, Bartuc will be encountered near the end of the activity after you have completed the last wave.
If you have chosen to face Bartuc by selecting The Bartuc Portal, he will appear in The Well of Hatred instead of the Fell Council.
This, however, will require that you have obtained a significant amount of Burning Aether, which is consumed to select the Bartuc Portal.
How To Challenge Bartuc, Lord of Chaos?
While you are running The Infernal Hordes activity, you will need to gather Burning Aether to challenge Bartuc, Lord of Chaos, at the end.
After the final wave, you will be able to choose between The Council Portal to fight the Fell Council or The Bartuc Portal to face the Lord of Chaos.
Challenging Bartuc will require that you spend exactly 666 Burning Aether, which is an amount that can often be reached with the help of Chaos Waves during the activity.
How To Defeat Bartuc, Lord of Chaos?
The fight against Bartuc, Lord of Chaos, is straightforward, focusing on dodging his attacks while dealing consistent damage whenever you find safe openings to strike.
Most of the battle revolves around evading his various attacks, which follow recognizable patterns that you can learn to anticipate and avoid with good timing.
Your main goal is to stay alive while delivering as much damage as possible during safe windows, gradually wearing him down until he is defeated.
Watch out for his fiery projectiles and the devastating energy blasts that shoot through the portals he spawns across the battlefield during the encounter.
Occasionally, he unleashes a pair of orbs tethered by electricity that move around the area, forcing you to dodge carefully to avoid taking heavy damage.
By keeping your distance, staying mobile, and punishing him during openings, you will eventually bring Bartuc down and claim his valuable loot and potential Chaos Armor reward.
Bartuc, Lord of Chaos Drops
Defeating Bartuc, Lord of Chaos, rewards you with a large haul of valuable loot, often including powerful Legendary gear and even highly coveted Unique items.
In Torment I and II, Bartuc has a chance to drop Chaos Armor, but in Torment III and IV, this exclusive Seasonal reward is guaranteed to drop.
His loot pool also includes valuable Crafting Materials, Infernal Warp, and other rare resources, making repeated fights against him well worth your time and effort.
Additionally, Bartuc is the only source of Unique Chaos Perks, which can be equipped to dramatically enhance your build and unlock new strategies during Season 10.
Farming Burning Aether
Farming Burning Aether is essential since challenging Bartuc, Lord of Chaos requires 666 Burning Aether, making efficient collection crucial for frequent boss attempts.
Choosing the right Infernal Offerings during the activity greatly impacts how much Burning Aether you gather before reaching the final confrontation.
The new Chaos Waves offer excellent chances to gather massive Burning Aether, spawning more enemies and rewarding fast, aggressive clearing between intense waves.
Using a strong, optimized build that clears enemies quickly is recommended, along with upgrading your gear and improving your Paragon Board for better efficiency.
Verdict
Bartuc, Lord of Chaos is not too difficult once you upgrade your gear and get used to dodging his predictable but punishing attack patterns.
During Season 10, Bartuc remains one of the most reliable sources of Chaos Armor, though you can still acquire pieces from other endgame activities.
Farming The Infernal Hordes while frequently challenging Bartuc is a strong way to level up, gather loot, and chase Chaos Armor throughout the season.
