Diablo 4 Season 10 - Season of the Infernal Reign - brings back the Viz-Jaq'taar faction system, rewarding players for diving into Chaos Rifts, Infernal Hordes, and other seasonal content. After completing Sands of Chaos, one of the first faction-related story quests, players will soon encounter Bartuc's Reign of Chaos, a repeatable reputation grind quest that appears between your major seasonal milestones.

At first glance, this quest can seem confusing - it doesn't point you to a location or objective marker. Instead, it simply tasks you with earning Viz-Jaq'taar Veneration reputation, scaling higher each time it appears. Below, we'll break down exactly how this system works, how to efficiently complete Bartuc's Reign of Chaos, and which methods yield the fastest reputation in Diablo 4 Season 10.

What Is Bartuc's Reign of Chaos in Diablo 4?

Bartuc's Reign of Chaos is a passive faction reputation quest that automatically triggers whenever you aren't progressing through a major seasonal story mission. You'll encounter this quest after Sands of Chaos and continue to see it between reputation rank milestones.

You receive a new story mission from the Viz-Jaq'taar faction every two reputation ranks - specifically at Ranks 2, 4, 6, 8, and 10. Between these thresholds, Bartuc's Reign of Chaos fills the gap, ensuring players still have a reason to farm reputation even when no story quest is active.

The quest objective will appear as:

"Earn Viz-Jaq'taar Veneration (0/X)"

Initially, this requirement starts at 150 reputation points, but it scales up each time you complete the quest. Later iterations may demand 500, 1,000, or even more, depending on your rank and seasonal progression.

While the quest itself doesn't feature unique combat objectives or story dialogue, it directly supports your long-term grind - unlocking Chaos Perks, Seasonal Blessings, and access to new seasonal challenges tied to Bartuc and the Viz-Jaq'taar.

Best Ways to Earn Reputation for Bartuc's Reign of Chaos

You can earn Viz-Jaq'taar reputation from multiple sources across Sanctuary during Season 10, but not all are equally efficient. Here are the top ways to progress Bartuc's Reign of Chaos quickly:

1. Prioritize the Urn of Reputation Blessing

The first and most impactful method is to invest your Seasonal Blessings into the Urn of Reputation.

You unlock Seasonal Blessings as you complete objectives in your Season Journey - specifically from Chapter 2 onward.

To access the Urn of Reputation:

·Finish the Chapter 2 objectives in your Season Journey.

·Complete the "Chaos Rises" objective, which requires:

·Reaching Rank 5 with Viz-Jaq'taar

·Collecting 5 Chaos Perks

·Closing 20 Chaos Rifts

Once unlocked, you can allocate Smoldering Ashes (earned via Season Pass progression) to the Urn of Reputation. Each rank grants +5% reputation gain from all sources, capping at +20%.

This multiplier applies to every activity that yields faction reputation, making it one of the most valuable long-term upgrades for completing Bartuc's Reign of Chaos faster.

2. Farm Chaos Rifts in Nightmare Dungeons

While Helltides are a reliable source of Chaos Rifts, Nightmare Dungeons with the Chaos Rift Affix are by far the best method for focused grinding.

Here's why:

·Chaos Rifts spawn more densely inside dungeons.

·You can chain runs without having to traverse large overworld maps.

·Dungeon layouts make it easier to corral enemies for AoE farming.

If you're lucky enough to find a Nahantu dungeon, these tend to have larger layouts and more rift spawns - translating to more reputation per run.

Pro Tip: Use crafted Nightmare Sigils to target Chaos Rift affixes. Salvage unneeded Sigils and craft new ones until you get a layout that suits your build.

Even better, some dungeons will spawn with a "+Reputation Modifier", further accelerating your progress. Always prioritize these when they appear in your inventory.

3. Run Helltides for Seasonal Caches

While Nightmare Dungeons are optimal, Helltides remain a strong source of both reputation and loot early in the season. You'll frequently encounter Chaos Rifts during these world events, and opening Seasonal Caches often rewards rare Diablo 4 Items and even materials for crafting Sigils.

Pro tip: Route your runs around the Chaos Rift icons on your map during active Helltides. Closing these efficiently increases your reputation rate while stacking resources that can be sold or used for upgrades. If you're low on currency or gear, this is also a great time to buy Diablo IV Items from eld.gg to optimize your build for faster Rift clearing.

4. Advance to Infernal Hordes in Torment Difficulty

Once your character is powerful enough to handle Torment difficulty, Infernal Hordes become the ultimate reputation farm.

In Infernal Hordes, you'll face waves of Chaos-fueled enemies while accumulating Aether, Chaos Waves, and Reputation simultaneously. The combination of dense mob packs and Chaos modifiers means faster progression overall.

Ideally, use 10-Wave Compasses for maximum chaos density and rewards. Even shorter compass runs are worthwhile, but the 10-wave format offers the best chance at spawning bonus Chaos Waves and elite encounters that grant extra Viz-Jaq'taar reputation.

Tip: Use Group Finder to run Infernal Hordes with others. Party scaling increases mob density and speeds up wave clears, resulting in faster reputation farming.

Recommended Builds for Bartuc's Reign of Chaos Farming

While any powerful endgame build can complete this quest, lightning-fast area-of-effect (AoE) builds perform best due to the large groups of enemies spawned by Chaos Rifts.

Consider builds such as:

·Sorcerer: Lightning Spear / Crackling Energy hybrid

·Barbarian: Whirlwind / Dust Devil build

·Rogue: Penetrating Shot / Death Trap hybrid

·Druid: Storm Claw or Pulverize Druid

·Necromancer: Minion Overlord or Blood Surge hybrid

The faster you clear enemies, the more rifts and chaos events you can complete per hour, directly boosting your reputation gains.

How the Quest Scales Over Time

Each time you complete Bartuc's Reign of Chaos, the required reputation increases. This scaling ensures steady progression without breaking the pacing of the seasonal grind. Eventually, higher thresholds will coincide with more rewarding seasonal quests, such as Den of Iniquity and beyond.

While the grind will grow longer with each iteration, maintaining the Urn of Reputation blessing and focusing on efficient content loops (Chaos Rifts → Infernal Hordes → Nightmare Sigils) will dramatically reduce the time needed per completion.

Final Thoughts

Bartuc's Reign of Chaos in Diablo 4 Season 10 might look like a filler quest, but it's the backbone of your Viz-Jaq'taar reputation progression. By optimizing your route, investing in the Urn of Reputation, and focusing on Chaos-heavy activities like Nightmare Dungeons and Infernal Hordes, you can breeze through this grind efficiently.

Complete it enough times, and you'll not only unlock the next seasonal storyline - Den of Iniquity - but also maximize your faction rewards, Chaos Perks, and seasonal cosmetics well before the season's end.

For dedicated players chasing every ounce of power, Bartuc's Reign of Chaos isn't just a task - it's a pathway to mastering the infernal balance of Season 10.
