Judicator’s Mask functions as a premium Lair Boss Key in Diablo 4, gating access to one of the game's most lucrative endgame rewards: Urivar’s Hoard. Introduced with the Vessel of Hatred expansion, this consumable item requires precise farming and strategic use to unlock a treasure trove of class-specific uniques, mythics, and materials that power top-tier builds. Since Season 8's overhaul, summoning Urivar costs nothing, but spending 12 masks post-fight delivers the real payoff, making every stack a ticket to progression.
Mechanics of the Mask and Summon
Players acquire Judicator’s Masks primarily through Torment-difficulty activities like Undercity of Kurast lairs, where they drop reliably every run under Tribute of Titans. Head to Fields of Judgement in Nahantu's upper-left region, clear the short dungeon to the altar, and summon Urivar freely. Defeat the boss—watch for his tracking light spears and knight summons—then insert 12 masks into the hoard chest. Each player in a group needs their own set, but parties rotate summons efficiently, turning solo grinds into shared windfalls. Urivar also drops Abhorrent Hearts as a bonus, fueling Harbinger of Hatred runs.
Urivar’s Hoard Loot Breakdown
The hoard guarantees one unique from Urivar's class-tuned pool, with extras pulling from general uniques at 50% odds, boosted by party size. Barbarians snag Ring of the Ravenous for rage stacking, Twin Strikes for dual-wield fury, Bane of Ahjad-Den, Overkill, or 100,000 Steps boots. Druids pull Gathlen's Birthright, Storm's Companion, Earthbreaker, Malefic Crescent, or Greatstaff of the Crone for nature mastery. Rogues get Orphan's Maker, Deathmask of Nirmitruq, Band of Ichorous Rose, or Scoundrel's Kiss. Necromancers claim Gospel of the Devotee, Sanguivor Blade of Zir, or The Unmaker for army dominance.
Spiritborns target Jacinth Shell, Wushe Nak Pa, or Band of First Breath, while Sorcerers chase Esadora’s Overflowing Cameo, Fractured Winterglass, Sidhe Bindings, or Okun’s Catalyst. Cross-class gems like Razorplate, Temerity, and Yen’s Blessing appear too. Mythic uniques such as Ahavarion Spear of Lycander, Tyrael’s Might, Heir of Perdition, Shroud of False Death, Shattered Vow, or Nesekem, The Herald have solid chances, especially in Tormented tiers—multiple mythics per open aren't rare in groups. Fillers include scaling gold, XP, runes, and crafting mats.
Maximizing Returns and Synergies
Efficiency skyrockets in Torment 4+ with speed builds, chaining lairs for mask replenishment mid-session. Groups amplify extra unique odds by 33% per member, while Belial ambushes post-boss add free loot. Rotate with Whispers and Helltides for passive masks, trading duplicates via bartering if needed. Pitfalls include low-gear wipes on spears or wasting masks below Torment—scale up deliberately. Patches tweak tables, but Urivar remains a mythic hotspot.
