Diablo 4: Bartuc, Lord of Chaos, Walkthrough (Season 10 Guide)

After completing Sword of Horazon in Diablo 4 Season 10, one final quest remains to Diablo 4 Items close out the story arc - Bartuc, Lord of Chaos. This climactic battle pits you against the infamous demonic mage himself, Bartuc, whose chaotic power tests your awareness more than your raw strength. Below is a complete walkthrough of the Bartuc Lord of Chaos quest, including how to start it, where to go, and how to defeat Bartuc efficiently.

How to Unlock Bartuc, Lord of Chaos in Diablo 4 Season 10

Before you can even take on this quest, you must reach Rank 10 in the Season 10 Reputation track. This reputation milestone unlocks the final seasonal mission, allowing you to embark on Bartuc's trail at your own pace. You don't need to be on Expert, Penitent, or Torment difficulty - any world tier will do.

Once you're eligible, travel to the Hidden Overlook, which becomes available on your world map after completing earlier Horazon-related quests.

If you haven't unlocked the waypoint, the fastest route is to fast travel to Fate's Retreat, then ride south toward Hidden Overlook. Upon arrival, talk to Shyan, the key NPC who guides you through the questline. Don't forget to activate the Hidden Overlook waypoint for easier access later.

Here's a quick breakdown of the Bartuc, Lord of Chaos, objectives in order:

1. Travel to the Hidden Overlook
2. Speak to Shyan
3. Travel to Bartuc's location
4. Speak to Shyan again

8. Find Bartuc, Lord of Chaos (final chamber)
9. Defeat Bartuc

Finding Bartuc in the Blistered Barrens

After speaking with Shyan at Hidden Overlook, she'll direct you south to the Blistered Barrens, where Bartuc has been sighted. The area is filled with infernal enemies and ambient chaos magic, so proceed carefully. Use your mount to travel quickly and avoid unnecessary combat along the way.

When you arrive at Bartuc's location, you'll meet Shyan again near the entrance to the Corrupted Palace - a once-secret refuge for mages who delved too deeply into demonic arts. She explains that Bartuc has twisted his power to fuel his resurrection. Your mission is clear: enter the palace and cleanse the corruption within.

Inside the Corrupted Palace

The Corrupted Palace operates like a standard Diablo 4 dungeon - a series of interconnected corridors filled with demonic foes and environmental traps. Fortunately, it's not sprawling or maze-like, making navigation straightforward.

As you progress, you'll eventually encounter two members of the Fell Council - powerful lieutenants resurrected to protect Bartuc. In most cases, these will be Wyand the Shadow and Bremm the Maelstrom, though the composition may vary between playthroughs.

During this battle, the enemies will trap you inside red energy lines that form a deadly perimeter. Touching these lines inflicts heavy damage, so stay inside the circle and focus on single-target elimination. Prioritize one enemy - Bremm tends to be more aggressive - and dodge the AOE fireballs and energy hydras they summon. The key is to stay mobile, using your class's movement skills to reposition quickly.

Once both are defeated, continue deeper into buy duriel mats the dungeon. You'll encounter a few more pockets of Fell Council defenders before reaching Bartuc's inner sanctum.
