Farm Betrayer's Husk in Diablo 4 by chaining Lair Boss hoards for Belial ambush spawns, plus Whispers and goblins, then spend 2 Husks to open Belial's chest for targeted endgame loot.
If you're chasing Betrayer's Husks for Belial in Diablo 4, you'll find out fast that "just grind more" isn't a plan. You need a loop that respects your time, especially if you're trying to farm Mythic Uniques on higher Torment. Some players even bridge the slow stretches by grabbing missing pieces through trading or services like U4GM, then spending their actual playtime on the content that pays out.
Belial Ambush Loop
Your main source is still Belial Ambushes. The trick is volume. Kill a standard Lair Boss, pop the hoard chest, and you've got a real shot that a smaller Belial shows up and tries to ruin your run. When it happens, it's quick and messy, and you're usually looking at two to four Husks if you win. Run this on Torment II or higher so the time feels worth it. And yeah, grouping helps a ton. In a party you can rotate summoning materials, keep the boss train moving, and roll the dice more times per hour. Solo works, but it's slower and it feels worse when the ambush just doesn't show.
Whispers, Goblins, and Free Rolls
While you're doing the boss circuit, stack passive chances too. Tree of Whispers objectives are perfect for that. You're already clearing dungeons, events, and odd jobs, so turning those into Whisper Caches gives you occasional Husk hits without changing your route. Don't expect consistency, just treat it as background progress. Also, if a Treasure Goblin appears, stop and delete it. During goblin-focused events, the rare material drops feel noticeably better, and even outside those windows it's still one of the few "free" detours that can actually spike your inventory. Keep an eye out for Apparition Incursions as well; filling the bar can spawn Belial's base form, which is basically another roll at Husks without spending boss mats.
Spending Husks Without Wasting Them
Once you've banked enough, go to the Palace of the Deceiver in Kehjistan, but only after you've cleared "The Lord of Lies." The key part is what happens after the fight: you spend two Husks to unlock his unique hoard, and you can choose which boss loot pool you want to pull from. That's huge for target farming. Don't rush it, though. If your build can't live through the poison phases, you're burning Husks for frustration. Cap poison resist, bring a plan for sustained damage, and save your attempts for the Torment tier you can comfortably clear. If you're missing a specific drop to finish the setup, it can help to check markets for Diablo 4 iteams so your Husk runs happen at full strength.
