How to acquire Loyalty's Mantle in Diablo 4
Like most Unique gear in Diablo 4, Loyalty’s Mantle can drop from various sources, but the most efficient method is target farming a specific boss.
Here are the best ways to obtain this Unique Helm:
1) Target farming Uber Boss – Grigoire, the Galvanic Saint

Since Loyalty’s Mantle is part of the boss-specific loot pool, defeating Grigoire multiple times is your best option for farming Loyalty's Mantle efficiently in Diablo 4.
To find Grigoire, the Galvanic Saint, you must go to the Hall of the Penitent in Dindai Flats, beside the Forgotten Depths dungeon.
2) Can be found as open world drops (from Enemies & Chests)
Loyalty’s Mantle can also drop randomly by defeating enemies and opening chests throughout Sanctuary in Diablo 4. To increase your odds:
- Participate in World Events (Gathering Legions, World Bosses)
- Run Nightmare Dungeons (higher difficulties improve drop rates significantly)
3) Drops during Helltide Events

Unique items, including Loyalty’s Mantle, can be found in Tortured Chests during Helltide Events in Diablo 4. Helltide Events spawn every hour, so keep an eye on the map and farm Cinders to open chests for potential drops.
Note that, if you die during the event, you will lose 50% of the Cinders you have collected. And if you haven't used all the Cinders during the event, they will vanish from inventory once the current event ends. So try and use as many Cinders as possible.
4) Gambling at the Purveyor of Curiosities

You can spend Murmuring Obols (Obols) at the Purveyor of Curiosities to gamble for gear in Diablo 4. While this option is quite unreliable, there’s a small chance for you to acquire Loyalty’s Mantle through random helmet rolls.
Best Builds for Loyalty's Mantle
Since Loyalty’s Mantle enhances matching Spirit Hall choices, it works best in builds that maximize its Spirit synergy. One of the most effective builds utilizing this helm is:
Loyalty Armor Jaguar Build (Spirit Hall - Jaguar)
This build focuses on agility and burst damage by using the Jaguar spirit in both Spirit Hall slots. With Loyalty’s Mantle, the Jaguar bonuses are doubled, granting massive increases to critical strike chance, attack speed, and evasiveness. The Cooldown Reduction & Vigor Cost Reduction allows you to spam high-damage mobility skills (like Rake and Rock splitter), making this build highly lethal in both PvE and PvP.
Conclusion
Loyalty’s Mantle is a powerful Unique Helm that strengthens the Spiritborn class in Diablo 4: Vessel of Hatred. With its affixes boosting movement, durability, and speed, along with its Unique Effect doubling Spirit Hall bonuses, this helm is a game-changer for Spiritborn builds, whole pushing the engine.
If you’re running a Spirit Hall-matching build, Loyalty’s Mantle is a must-have, offering you unparalleled synergy and power.
