Diablo 4: How to FARM AMULETS with Passive Ranks at the Undercity

In Diablo 4, few pieces of gear are as impactful as a perfectly rolled amulet. While weapons and armor define your raw power, amulets often determine how strong your build truly feels thanks to one special type of affix: Passive Ranks. These affixes increase the level of specific passive skills, effectively giving you “free talent points” that stack beyond the normal skill tree limits.

With the introduction of the Kurast Undercity, players finally have a semi-targeted way to farm amulets with passive ranks instead of Diablo IV Items relying purely on RNG. This method is currently one of the most efficient endgame loops for min-maxing builds, especially for high-tier Nightmare Dungeons and endgame bosses.

Why Passive Ranks on Amulets Are So Powerful

Passive rank affixes increase the level of key passives such as:

Damage multipliers

Resource generation

Critical strike bonuses

Damage reduction and survivability

For example, getting +2 ranks to a core passive like a Barbarian's Heavy Handed or a Sorcerer's Glass Cannon can easily outperform multiple flat stat rolls combined. Since amulets can roll multiple powerful affixes at once, a good passive roll can turn an average build into a top-tier one.

The problem? Passive ranks are rare and usually appear randomly on amulets… unless you use the Undercity correctly.

Understanding the Kurast Undercity System

The Kurast Undercity is a special endgame activity that allows players to influence loot outcomes through a system of Tributes and Bargains.

Before entering a run, you:

Insert a Tribute (usually Tribute of Radiance).

Select a Bargain, which modifies what kind of loot you'll receive.

Pay the gold cost for the chosen bargain.

One of the most important bargains available is the Passive Ranks Bargain, which heavily biases amulet drops toward having at least one passive rank affix.

This doesn't guarantee a perfect amulet, but it massively increases your odds compared to world drops, dungeons, or bosses.

Step 1: Farming Tributes of Radiance

To start farming, you need a steady supply of Tributes of Radiance. These are consumed every time you launch a targeted Undercity run.

The best ways to obtain them are:

World events and open-world activities

World bosses

Seasonal activities

High-tier content like Helltides and endgame events

In practice, the fastest method is repeatedly farming open-world events while rotating between zones. With proper seasonal bonuses, you can stockpile dozens of tributes in a single session.

Think of tributes as your “fuel” for amulet farming. The more you have, the more attempts you get.

Step 2: Selecting the Passive Ranks Bargain

Once inside the Undercity menu:

Insert your Tribute of Radiance.

Choose the Passive Ranks Bargain.

Pay the gold cost (usually very high, often around 50 million gold).

This bargain ensures that legendary amulets dropped during the run are extremely likely to roll with at least one passive rank affix.

This is the core of the method. Without this bargain, you are just doing another random dungeon.

Step 3: Running the Undercity Efficiently

Inside the Undercity, your goal is not just speed, but progression quality.

To maximize rewards:

Kill elite packs and mini-bosses.

Fill the progression bar before rushing the final boss.

Avoid skipping side objectives if they increase reward tiers.

The better your performance inside the dungeon, the more high-quality legendary and ancestral items you'll receive at the end.

Ideally, each run should give you multiple legendary amulets, increasing your chance of hitting a top-tier passive roll.

Step 4: Using Seasonal Powers for Extra Efficiency

In recent seasons, two seasonal powers dramatically improve this loop:

Essence of Sin

Increases the number of tributes dropped from world activities. This makes farming tributes significantly faster and less grindy.

Essence of Anguish

Boosts the amount of Opals earned in the Undercity. Opals are used for gambling additional items, including amulets.

With both active, your loop becomes:

World content → More tributes → Undercity runs → Opals → Amulet gambling → Back to Undercity

This creates a self-sustaining farming cycle.

Step 5: Gambling with Opals for Extra Amulets

After a few Undercity runs, you'll hit the Opal cap. Instead of letting them overflow, spend them at the gambling vendor to roll more amulets.

These gambled amulets are not guaranteed to have passive ranks, but they are essentially “free rolls” layered on top of your main farming method.

Over time, this dramatically increases your total number of amulets per hour.

What Makes a “God Roll” Passive Amulet?

When evaluating your drops, look for:

+2 or +3 to a core passive

Synergy with your main build mechanic

Useful secondary stats like:

Cooldown reduction

Resource cost reduction

Damage to close/distant enemies

Movement speed or resistances

Even a single high passive roll can beworth keeping if the other stats are rerollable.

Common Mistakes to Avoid

Ignoring gold management – This method is expensive. You'll need millions per session.

Rushing runs too fast – Skipping progression reduces loot quality.

Expecting perfection instantly – You'll still get many mediocre rolls. That's normal.

Not stacking seasonal bonuses – These massively impact efficiency.

Final Thoughts

Farming amulets with passive ranks at the Kurast Undercity is currently the closest thing cheap Diablo 4 Items has to targeted gearing. Instead of praying for luck, you actively influence the loot system to favor the most valuable affix type in the game.

While it still relies on RNG, this method transforms amulet hunting from a frustrating grind into a structured endgame loop. With enough tributes, gold, and patience, you can realistically farm multiple endgame-worthy amulets in a single day.

For serious players pushing high-tier content, mastering the Undercity passive amulet farm is no longer optional — it's one of the strongest optimization tools in Diablo 4.
