To obtain the Corrupted Lightbringer, players need to defeat Yulivar or Vashan, two high-level bosses in Diablo IV Season 9. Both of Diablo IV gold these bosses have a chance to drop the Corrupted Lightbringer, but you must first unlock their treasures by collecting specific materials from the surrounding areas.



1. Yulivar: Boss of Kurast

Yulivar is located in a lair to the west of Kilchuk in the Kurast region. This lair is filled with tough enemies, and players must fight their way through them to face Yulivar. Once Yulivar is defeated, you will be able to access Yulivar’s Hoard.



However, opening the hoard requires 12 Masks of the Judge, which drop from enemies in the Kurast Undercity. You will need to farm these materials from the Undercity before you can open Yulivar’s treasure chest and claim the Corrupted Lightbringer.



2. Vashan: Boss of the Whispering Tree

Alternatively, Vashan is located in an underground cave near the Whispering Tree. Like Yulivar, Vashan also has the chance to drop the Corrupted Lightbringer, but to unlock Vashan’s Hoard, you’ll need 12 Vicious Hearts, which drop from enemies in the Whispering Hoard.



After gathering the necessary materials, you can open Vashan’s Hoard and potentially acquire the Corrupted Lightbringer, as well as other valuable loot.



3. Purchasing Materials from Faila

If you’re finding it difficult to farm the required materials, there’s a cheap Diablo 4 gold shortcut available. You can purchase Pale Mark boss materials from Faila in the Lair. Alternatively, you can collect these materials through Titan Tributes in the Kurast Undercity. Using these materials will allow you to more easily open the boss treasures, speeding up the farming process for the Corrupted Lightbringer.
