If you want to unlock powerful loot chests from Lair Bosses in Diablo 4, you need to gather specific boss materials. There are five Initiate Lair Bosses, three Greater Lair Bosses, and one Exalted Lair Boss, Belial, Lord of Lies.

Each boss needs different materials like Living Steel, Distilled Fear, Malignant Heart, or the Betrayer’s Husk for Belial. Gathering these materials isn’t straightforward, so here’s how to do it efficiently Diablo 4 Items.

First, farm Undercity Tributes from Helltides. Kill Blood Maidens and open Helltide Chests to find Tributes of Titans. These are special because they increase boss materials rewards during your next stage of farming.

Baneful Hearts are handy — use them to summon Blood Maidens, giving you a better chance of getting Tributes. Completing Whispers in Helltides quests will also reward you with Whisper Caches that may contain Tributes.

After collecting many Tributes of Titans, run Kurast Undercity over and over. Spend the Tributes to increase the rewards of boss materials you receive. If you don’t have the Vessel of Hatred DLC needed to enter Kurast Undercity, keep farming Blood Maidens with Baneful Hearts.

Once you’ve collected plenty of materials from Initiate Lair Bosses, move on to Greater Lair Bosses, then prepare for Belial’s incursions to gain the special Betrayer’s Husks buy Diablo 4 Items.

This two-part farming method is an effective way to maximize your loot chances and quickly stockpile needed materials in Diablo 4.
