Diablo 4 Season 10: Best Route to Farm Lair Boss Materials Fast

An essential part of Diablo 4's endgame is challenging the game's devastating Lair Bosses-elite endgame encounters that reward players with Diablo 4 Items build-defining Mythic gear. Once players reach Torment 1 difficulty, they gain access to the Lair Boss ladder, where each victory can yield some of the most powerful Uniques and Mythics in the game. However, these bosses aren't simple loot pinatas-you'll need specific boss materials to unlock the rewards from their loot chests after defeating them.

For players aiming to farm Lair Bosses efficiently in Diablo 4 Season 10, the key lies in gathering boss materials first. Unfortunately, these materials aren't guaranteed drops, but there's a highly effective two-step farming strategy that maximizes your chances. By combining Helltides and the Kurast Undercity from the Vessel of Hatred DLC, players can reliably stockpile every material needed for the Initiate, Greater, and even Exalted Lair Bosses.

The 9 Lair Bosses and Their Materials

Each of Diablo 4's Lair Bosses has a unique material required to open its reward chest after defeat. These are the key materials and their associated bosses:

Girgoire - Living Steel

Beast in the Ice - Distilled Fear

Echo of Varshan - Malignant Heart

Lord Zir - Exquisite Blood

Urivar (DLC Only) - Judicator's Mask

Duriel - Shard of Agony

Andariel - Pincushioned Doll

Harbinger of Hatred (DLC Only) - Abhorrent Heart

Belial, Lord of Lies - Betrayer's Husk

While the Initiate Lair Bosses (Girgoire, Zir, Varshan, Beast in the Ice, Urivar) are the most efficient for farming Diablo 4 materials, this route also gives a decent supply for Greater and Exalted Bosses-particularly Duriel, Andariel, and Belial.

Farm Undercity Tributes from Helltides

The first half of this farming loop is all about Helltides-the dynamic, demon-filled world events that reset every hour. Helltides are packed with opportunities to earn Undercity Tributes, a currency required to amplify material drops from the Kurast Undercity dungeon.

Players should specifically focus on farming Tributes of Titans, as these increase the rewards from successful Undercity runs when you achieve Rank 1 completion. You can earn Tributes by:

Defeating Blood Maidens (summoned using Baneful Hearts)

Opening Helltide Chests

Completing Whispers within Helltides, then opening the Whisper Cache

It's a good idea to contribute Baneful Hearts during the Blood Maiden summoning ritual. This not only increases your personal Tribute drop chances but can also drop boss materials directly, making this stage a double-dip opportunity're farming both Tributes and materials simultaneously.

Spend Tributes in the Kurast Undercity Dungeon

Once you've stocked up on Tributes of Titans, it's time to move into the Kurast Undercity, a dungeon accessible in the Vessel of Hatred DLC. Each Tribute of Titans you use increases the drop rate and quantity of Lair Boss materials earned at the end of cheap d4 mats a successful run.
