The endgame in Diablo IV is no longer just about killing monsters and hoping for lucky drops. With the current seasonal systems, War Plans, the Horadric Cube, D4 Gold, and specialized tributes all working together, efficient farming has become one of the most important parts of character progression.

Whether you are trying to push Paragon levels, hunt Mythic Uniques, stack Forgotten Souls, or build perfect ancestral gear, understanding where to spend your time can dramatically speed up your progression. Some activities are excellent for quick bursts of rewards, while others provide steady long-term value over hundreds of runs.

This guide breaks down the best farming methods for nearly every important resource in Diablo 4’s endgame and explains how to maximize efficiency while progressing your character.

Echoing Hatred: The Ultimate All-in-One Farming Activity

One of the rarest but most rewarding activities currently available is Echoing Hatred. Accessing it requires finding a Trace of Ekko item, which acts as the key to the event. These keys are extremely uncommon, with many players only seeing a handful across dozens of hours of endgame grinding.

Undercity runs appear to have the highest chance of dropping these keys, especially at higher tournament difficulties where boosted drop rates are active.

Once activated, Echoing Hatred becomes a wave-based challenge that continuously scales upward in difficulty. The activity starts around normal difficulty levels and climbs through increasingly difficult Pit-style tiers until you either die or fail to clear within the timer.

The reward structure is what makes this activity incredible. Every tier cleared improves your payout, and the rewards include:

Forgotten Souls

Seals

Charms

Legendary gear

Crafting materials

High-tier loot

General progression resources

Because rewards scale with your performance, it is often best to save these keys until your build becomes stronger. However, using one earlier can still provide a massive injection of materials if you are stuck progressing.

Even at lower tiers, Echoing Hatred is one of the most rewarding activities in the game.

Best XP Farming Methods

Experience farming remains the backbone of Diablo 4’s endgame because Paragon progression massively increases your overall power.

Currently, there are three standout methods for farming XP efficiently.

1. Whispers of the Dead

Whispers remain one of the best passive XP systems in the game, especially when paired with the War Plan node that increases Whisper cache experience rewards by 50%.

These caches already provide substantial experience, but the War Plan bonus pushes them into elite territory for leveling efficiency.

The best strategy is to combine Whispers with activities you are already running naturally. Every 30 minutes, check the map for a Lair Boss marked with Whisper rewards.

For example:

Harbinger of Hatred may reward five Grim Favors

Boss kills usually take under a minute

Five Grim Favors equals half a Whisper cache

This means you can earn massive XP gains with minimal effort simply by checking rotating objectives every half hour.

Whispers are especially powerful because they stack passively with nearly every other activity in the game.

2. Undercity XP Farming

Undercity is arguably the strongest overall seasonal activity right now, especially with the correct War Plan setup.

Several War Plan nodes dramatically increase XP gains:

Bonus XP from Attunement levels

Portal Prankster rewards

XP tribute bonuses

Additional reward chests

Using the Tribute of Growth specifically transforms Undercity into an elite XP farm. Each Portal Prankster killed grants bonus XP orb chests at the end of the activity, resulting in huge experience spikes.

The left-side War Plan path becomes especially important because it enables bonus chests that duplicate the rewards of your chosen tribute.

This scaling system is what makes Undercity so valuable throughout the entire season.

3. Pit Runs

Pit farming becomes extremely powerful once enough War Plan points are invested.

The essential nodes are:

Heart of Stone

Cororon Soul

Damned Thieves

These upgrades create additional Progress Orbs throughout the Pit while also granting experience every time one is collected.

The synergy is incredibly efficient:

More orbs spawn

Each orb grants XP

Faster Pit clears generate even more XP

Once fully optimized, Pit runs become one of the fastest long-term Paragon leveling methods available.

Farming Ancestral Base Items

The Horadric Cube makes crafting significantly more flexible this season, but you still need strong base items to begin with.

Specifically, you want Ancestral gear.

The easiest source of raw Ancestral items is the Purveyor of Curiosities vendor.

Using Murmuring Obols, you can spam-purchase targeted gear slots until good ancestral bases appear.

For example:

Buy boots repeatedly

Look for useful defensive affixes

Use the Cube to reroll bad stats later

Even imperfect ancestral items can become powerful with proper crafting.

Loot Filter Optimization

One of the smartest farming tricks involves the loot filter system.

Instead of highlighting everything, many experienced players only filter for premium affixes such as:

Resistance to All Elements

Critical Strike Multiplier

Cooldown Reduction

High-value defensive stats

Resistance to All Elements is especially valuable because it is extremely difficult to roll naturally through crafting.

By color-highlighting only premium affixes, you dramatically improve farming efficiency and avoid inventory clutter.

Best Crafting Material Farms

Cube crafting requires enormous amounts of materials over time.

The best sources are:

Undercity Tribute of Ingenuity

This tribute provides massive crafting material rewards, especially when combined with Portal Prankster War Plan bonuses.

Higher-tier versions provide even greater payouts.

Materials Reserve Nightmare Dungeons

These sigils remain one of the best fallback options if you lack strong Undercity tributes.

Standard Dungeon Farming

Even regular dungeons provide respectable crafting material gains if run efficiently.

Farming Legendary Aspects

Target-farming legendary aspects has become much easier thanks to the Cube’s Upgrade to Legendary feature.

The strategy works like this:

Acquire ancestral rares from Purveyor of Curiosities

Choose item slots tied to desired aspect categories

Upgrade them into legendaries

For example:

Boots mainly roll Utility and Mobility aspects

This narrows the aspect pool significantly

Repeated upgrades improve your chances of finding max-roll aspects

Because ancestral items can roll maximum aspect values, this system is ideal for min-maxing builds.

Best Methods for Farming Uniques

Unique farming depends heavily on what item you need.

Boss Target Farming

Each Lair Boss has specific loot pools, making boss targeting the most direct farming method.

War Plan nodes improve this system further by allowing certain unique pools to drop outside their normal boss encounters.

This is especially valuable for bosses like Astaroth, who normally require escalation sigils to access.

Lair Boss Enhancements

Several War Plan upgrades significantly improve boss farming efficiency:

Lair of Plenty grants extra Horde chests

Nemesis paths spawn additional bosses

Bonus bosses create massive loot explosions

These upgrades greatly increase the number of uniques earned per run.

Horadric Cube Unique Crafting

The Cube can also directly create unique items.

The process works like this:

Obtain an ancestral rare item

Remove all affixes

Convert it into a common ancestral item

Use Upgrade to Unique

This transforms the item into a random unique from that gear slot.

For example:

Ancestral boots become random unique boots

Repeat until desired unique appears

This system also works for crafting unique charms used in the Talisman system.

Mythic Unique Farming

Mythic Uniques remain the rarest and most powerful items in Diablo 4.

The absolute best farming method is:

Mythic Tribute of Armaments + Undercity

With proper War Plan investment, Portal Pranksters create extra reward chests that duplicate Mythic tribute rewards.

This means:

More Portal Pranksters = more Mythic reward chests

Bonus locked chests can also duplicate Mythic loot

Multiple Mythic drops become possible in a single run

This setup currently represents the strongest Mythic farming strategy in the game.

Outside of Undercity, Uber bosses like Uber Mesto remain valuable but require limited keys and significantly more difficulty.

Best Seal and Charm Farming

Once again, Undercity dominates.

Using the Tribute of the Harajum grants large quantities of:

Seals

Charms

Legendary charm variants

Combining this with Portal Prankster bonuses massively increases efficiency.

Nightmare Dungeons and Lair Bosses also provide decent secondary farming options.

Rune Farming and Rune Upgrading

Runes now feel far more accessible thanks to Cube conversion systems.

Boss kills remain the primary source of runes, though Lair Bosses require a War Plan node to restore their rune drop rates.

The Cube allows several useful conversions:

5 blue runes → random yellow rune

5 yellow runes → random legendary rune

3 legendary runes → new random legendary rune

This finally gives players a realistic path toward targeted rune progression instead of relying entirely on RNG.

Fastest Gem Farming Method

For gem fragments, dungeon bosses remain king.

One standout location is Sears Reach near Temis.

Why it works:

Extremely short dungeon

Quick boss access

Fast reset times

Reliable gem rewards

Each boss kill drops multiple Royal Gems.

Over time:

10 Royal Gems = Grand Gem crafting

5 Grand Gems = Horadric Gem conversion

This creates one of the fastest gem progression loops in the game.

Forgotten Souls Farming

Forgotten Souls are arguably the biggest late-game bottleneck.

Ancestral upgrades consume huge amounts of them, especially when heavily crafting or rerolling gear.

Best farming sources include:

Seasonal Capstone Objectives

Large one-time bursts of Forgotten Souls.

Legion Events

Excellent efficiency for time invested.

Materials Reserve Nightmare Dungeons

One of the best repeatable farming methods.

Whisper Material Caches

Reliable supplemental source.

War Plan Reward Chests

Surprisingly solid for passive accumulation.

Best Gold Farming Methods

Gold becomes increasingly important as crafting costs skyrocket.

The easiest gold strategy is selling excess:

Legendary seals

Set bonus charms

Unused high-rarity items

Legendary seals alone can sell for over 13 million gold each.

Unique charms can sell for around 8 million, though salvaging them may sometimes be more valuable depending on your crafting needs.

Many players underestimate how much passive gold they are sitting on simply because inventory management becomes overwhelming in the late game.

Regularly clearing junk items can generate enormous amounts of currency with almost no effort.

Final Thoughts

This season of Diablo 4 has created one of the deepest farming ecosystems the game has ever had. Between the Horadric Cube, War Plans, Undercity scaling, tribute systems, and boss targeting, players now have multiple ways to pursue almost every resource in the game.

However, one activity clearly stands above the rest: Undercity.

With the correct War Plan setup, Undercity becomes:

One of the best XP farms

One of the best Mythic farms

One of the best material farms

One of the best seal and charm farms

One of the best overall progression systems

Meanwhile, Echoing Hatred serves as an incredible high-value activity whenever players are lucky enough to obtain a key.

Ultimately, the best farming strategy is not focusing on only one resource at a time, but layering activities together so progression happens naturally across multiple systems simultaneously. Players who optimize their War Plans, prioritize efficient routes and cheap Diablo 4 Items, and understand which systems synergize best will progress dramatically faster than those simply grinding random content endlessly.

As Diablo 4’s endgame continues evolving, mastering these farming systems is quickly becoming just as important as mastering your build itself.
