Forget everything you knew about farming Mythics in Diablo 4: Lord of Hatred—the community just discovered an unbroken, endless endgame loop that targets two major Mythic drop sources simultaneously! 🤯🔥

If you are still mindlessly running individual dungeons hoping for a random drop, you are wasting your time. Top theorycrafters have just cracked a brilliant “neverending” farming cycle that feeds into itself, letting you chain high-density endgame encounters back-to-back without ever running out of keys or tributes. By combining specific Paragon War Plans nodes with a hidden Horadric Cube crafting chain, players are turning useless dungeon garbage into the highest tier loot keys in the game.

The best part? This isn’t a glitch that will get you banned; it’s a hyper-efficient use of game mechanics that utilizes an obscure vendor trick most players are completely ignoring.

Want to know the exact 25-to-1 crafting recipe, the specific Blacksmith-only salvage loophole, and how to trigger the “Prankster” spawns for maximum drops? 👇

The race for perfect endgame gear in Diablo IV: Lord of Hatred has reached a fever pitch, and the community has just uncovered a highly sophisticated, legitimate farming loop that targets multiple Mythic item sources simultaneously.

Unlike pure exploits that rely on glitching map barriers or breaking AI triggers, this new strategy is a masterclass in mechanic synergy. Discovered and popularized by prominent theorycrafters, including YouTuber Sliver of time, the method establishes an infinite, self-sustaining loop between two of the expansion’s most lucrative endgame activities: the escalating Nightmare Dungeons featuring Astaroth, and the high-octane Kurast Undercity.

The breakthrough has sparked massive discussion across Reddit and Discord, as casual and hardcore players alike abandon traditional grinding patterns to adopt the new “neverending” meta.

Setting Up the War Plans

The efficiency of the loop hinges on specific node allocations within the expansion’s newly introduced War Plans system. To initiate the farm, players must invest three points into the Nightmare Dungeon branch to unlock the Branching Pathways node. This particular node grants players a choice between three distinct affixes when progressing through escalating Nightmare Dungeons, providing vital control over endgame drops.

Simultaneously, players must venture into the Kurast Undercity section of the War Plans and secure the Gutter Filth node. This node ensures that interacting with any beacon inside the Kurast Undercity has a distinct chance to spawn a “Prankster” enemy. Eliminating these Pranksters dramatically escalates the final reward tier at the completion of an Undercity run.

Once these foundational nodes are active, the mechanical engine of the loop is ready to fire.

Phase 1: The Astaroth Sigil Engine

The loop begins with a baseline investment of four Escalating Nightmare Dungeon Sigils, which can be synthesized by combining five standard Nightmare Dungeon Sigils within the Horadric Cube.

As players execute these escalating runs, the Branching Pathways node proves its value. While early affix choices can be tailored to immediate needs like gold or gem fragments, the final choice leading up to the confrontation with Astaroth requires strict adherence to the strategy. Players must exclusively select the option labeled Richest of Keys.

When Astaroth is defeated under the influence of this affix, his loot table is forced to drop an abundance of standard Nightmare Dungeon Sigils, Infernal Horde Compass keys, and crucially, additional Escalating Nightmare Dungeon Sigils. This ensures that the initial investment of four escalating sigils is not only recovered but consistently multiplied. Astaroth himself acts as the first primary drop vector for highly coveted Mythic Seals.

The Blacksmith Salvage Loophole

The transition from the dungeon phase to the city phase relies on an unorthodox inventory mechanic that initially baffled many community members.

After multiple successful Astaroth clears, a player’s inventory inevitably overflows with excess sigils. The strategy dictates that players must return to town and salvage every Escalating Nightmare Dungeon Sigil beyond their baseline starting pool of four. However, this process contains a critical caveat: this salvage can only be performed by the Blacksmith.

Due to an apparent development oversight or hardcoded classification within the Lord of Hatred expansion, the Occultist—the traditional vendor for all things occult and sigil-related—is completely incapable of breaking down Escalating Nightmare Dungeon Sigils. Attempting to do so results in a UI error. Players must utilize the Blacksmith to melt down these high-tier sigils, alongside traditional methods to salvage standard sigils, yielding massive quantities of Sigil Powder.

Phase 2: Horadric Cube Math and Kurast Undercity

With bags full of Sigil Powder, players visit the Occultist to mass-craft blue-quality Kurast Undercity Tributes. The goal of this crafting spree is to accumulate Lesser Horadric Tributes.

From here, the Horadric Cube becomes the centerpiece of the progression economy. The conversion math is strict and linear:

5 Lesser Horadric Tributes (Blue) are transmuted into 1 Horadric Tribute (Yellow).

5 Horadric Tributes (Yellow) are transmuted into 1 Greater Horadric Tribute (Legendary).

A total investment of 25 baseline Lesser Horadric Tributes is required to forge a single Greater Horadric Tribute.

This Legendary-tier tribute is then plugged into the Kurast Undercity brazier to launch a high-tier city run. The Greater Horadric Tribute forces the final Undercity boss to drop an immense bounty of Talisman items. In Lord of Hatred, the drop rate of Mythic Seals is directly tied to the volume of Talismans awarded; the more Talismans that drop, the higher the mathematical probability of a Mythic Seal appearing.

During the Undercity run, the previously unlocked Gutter Filth node comes into play. By hunting down the triggered Prankster spawns across the map, players maximize their final loot chests, squeezing every drop of value out of their hard-earned Legendary tribute.

An Infinite Cycle

The brilliance of the strategy lies in its closed-loop nature. Because Phase 1 generates more than enough sigils and materials to sustain both the baseline dungeon pool and the Sigil Powder required for Phase 2, players never hit a progression wall. Once the Kurast Undercity boss is slain, players simply pocket their loot, step back out to the dungeon gates, and restart the Astaroth engine.

Community reception on the r/diablo4 subreddit has been overwhelmingly positive, with many praising the loop for making the endgame grind feel deliberate and rewarding rather than purely reliant on open-world RNG.

“This is exactly what the expansion needed,” wrote one veteran player on X. “It links the new systems together perfectly. You aren’t exploiting the game, you’re just playing it smarter than everyone else.”

As of publication, the loop remains fully operational. Because it relies on intended crafting systems and core expansion features, it is highly unlikely to face the threat of a hotfix or developer intervention—making it the definitive blueprint for Mythic farming in Season 4.
