Diablo 4’s Lord of Hatred expansion has revamped the Diablo IV Items endgame grind, making Forgotten Souls, Horadric Cube materials, and Lair Keys more critical than ever for character progression. Whether you’re chasing perfect gear rolls, unlocking cube recipes, or tackling endgame bosses, farming these resources efficiently can save you hours of tedious grinding. This guide breaks down the fastest, most reliable methods to farm all three, so you can focus on optimizing your build instead of wasting time on low-yield activities.

Forgotten Souls: The Core of Endgame Crafting

Forgotten Souls are non-negotiable for masterworking, enchanting, and upgrading ancestral gear—without them, you’ll hit a wall in your endgame progression. The good news is that recent patches have buffed their drop rates, making fast farming easier than ever.

The absolute best method for Forgotten Souls is farming Legion Events on Torment IV. These events spawn every 25 minutes and take only 3 minutes to complete, yielding 200–250 Forgotten Souls per run alongside veiled crystals and ancestral loot. With this rhythm, you can easily farm 500+ Forgotten Souls per hour.

Between events, you can fill gaps with quick Nightmare Dungeon runs that have the “Horadric Material Reserve” affix—these dungeons have hidden chests that drop 15+ Forgotten Souls each, though they’re less consistent than Legion Events.

Cube Materials: Maximize Efficiency with Smart Rotations

The Horadric Cube, unlocked after completing the Lord of Hatred campaign, is a game-changer for endgame progression—it lets you reroll affixes, upgrade gear, and turn junk loot into valuable items. To use it effectively, you need a steady supply of cube materials like Obducite, Primordial Dusts, and Infused Horadric Resin.

The fastest way to farm Obducite (a key cube material) is the Lair Boss Teleport Trick. Open a Nightmare Dungeon with a Horadric Strongroom (e.g., Uldur’s Cave) and teleport directly to Lair Bosses like Gregoire or Lord Zir. If a boss has a purple flame, a Horadric Strongroom has spawned—clearing it yields 2,000–2,500 Obducite in just a few minutes.

For alternatives, try Tribute of Refinement runs in Kurast Undercity (2,000 Obducite in 2–3 minutes) or 8-wave Infernal Hordes (2,000–3,000 Obducite in 10 minutes). Primordial Dusts, meanwhile, drop from elite monsters, War Plans, and Tree of Whispers caches—integrate these into your rotation to avoid material bottlenecks.

Lair Keys: Unlock Boss Hoards Without the RNG Frustration

Lair Keys are your ticket to endgame boss hoards, which contain unique items and top-tier gear. The biggest myth about Lair Keys is that higher Torment tiers increase drop rates—instead, focus on completing as many activities as possible per hour, even on lower Torment difficulties.

The most efficient Lair Key farm is chaining Lair Boss runs (using the same teleport trick for Obducite). Lair Bosses drop keys consistently, and you can reset their spawns by cycling through different bosses in your rotation. World Bosses and Tree of Whispers bounties also drop keys, but they’re less reliable.

Don’t forget there are two key tiers: normal Lair Keys for standard bosses and Greater Lair Keys for Torment VI+ bosses. Craft extra keys at the Alchemist if you run low—they require common materials like Stygian Stones or Khazra Horns, making them easy to replenish.

The Ultimate Farming Rotation: No Downtime, Maximum Rewards

To farm all three resources at once, use this optimized rotation: First, check the next Legion Event. If you have 15–20 minutes until it spawns, start the Lair Boss loop to farm Obducite and Lair Keys simultaneously.

Mix in quick Tribute of Refinement runs if you have tokens, or Tree of Whispers bounties for extra Primordial Dusts. When the Legion Event starts, drop everything to run it—this gives you a massive Forgotten Souls boost.

Repeat this loop, and you’ll farm Forgotten Souls, Cube Materials, and Lair Keys at maximum efficiency. Remember to salvage duplicate gear and unused sigils to keep your materials stocked, and use the Horadric Cube to turn excess loot into useful resources.

With these methods, you’ll skip the tedious grind and focus on what matters: building your perfect character. The Lord of Hatred’s endgame is challenging, but with a buy Diablo IV Items smart farming strategy, you’ll have all the resources you need to dominate every corner of Sanctuary.
