MMOexp: How to Obtain Rotting Lightbringer in Diablo 4
Yulivar is located in a Diablo IV gold 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.
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 Diablo IV Items drop the Corrupted Lightbringer, but to unlock Vashan’s Hoard, you’ll need 12 Vicious Hearts, which drop from enemies in the Whispering Hoard.
