In Diablo 4, collecting boss materials is essential to unlock powerful loot chests after defeating Lair Bosses. There are different levels of Lair Bosses: Initiate, Greater, and Exalted. Each boss drops unique materials you need to open their treasure.
For example, Girgoire drops Living Steel, the Beast in the Ice drops Distilled Fear, and Belial, the Exalted Lair Boss, requires a Betrayer’s Husk. Other bosses like Duriel and Andariel also have their specific materials.
To farm these materials effectively, you can start by gathering Undercity Tributes from Helltide events. You want to focus on Tributes of Titans because they increase your boss materials reward in the next step — running the Kurast Undercity dungeon buy Diablo 4 Items.
The way to get lots of Tributes of Titans is by defeating Blood Maidens and opening Helltide chests. Using Baneful Hearts to summon Blood Maidens makes the drops more frequent. Plus, you can complete “Whispers in Helltides” for a chance to get a Whisper Cache, which might also contain Tributes.
Once you have enough Tributes of Titans, it’s time to run the Kurast Undercity dungeon repeatedly, using those Tributes to boost your loot drops from bosses inside. If you don’t have the Vessel of Hatred DLC and can’t access the Undercity, your best bet is to stick with farming Blood Maidens during Helltides.
After collecting enough Initiate Lair Boss materials, you can focus on obtaining materials for Greater Lair Bosses and the powerful Belial, Lord of Lies, who needs Betrayer’s Husks to open his chest Diablo 4 Items.
By using this two-step farming method, you improve your chances of finding valuable boss materials quickly and reliably, which is key to gearing up in Diablo 4.
