Diablo 4 Belial: How to Summon and Kill the Lord of Lies

Belial sits at the top of the Lair Boss ladder as its Exalted tier. Reaching him takes 3 things.

1. Torment 1 or higher. Lair Bosses open only on the Torment difficulties.
2. The Palace of the Deceiver. His lair is in Kehjistan, west of the Tarsarak waypoint. The altar inside starts the fight.
3. Superior Lair Keys for the Hoard. The fight itself costs nothing. The keys open his Hoard after the kill.

Every player in the group spends their own key on their own Hoard. No keys yet? A Pro group can run the kills on your account.

Kill any other Lair Boss, and Belial sometimes ambushes you at the end. The chance is small.

This smaller form of Belial drops Superior Lair Keys. Beat him, and the keys drop with a 2nd round of loot from the boss you just killed.

So the key farm is a Lair Boss farm. Every Duriel or Andariel run is another roll for the ambush. Our Duriel guide covers the Initiate boss loop behind his keys.

Belial fights on a long platform with poison and claw attacks.

• Claw swipe. He drives a claw into the platform and drags it across. Keep off the upper side of the platform when it starts.
• Poison stream. He spits poison from 1 end of the platform to the other. The stream leaves pools behind. Start on the far side and move to clean ground.
• Poison waves. Pools slide across the platform from left to right. Step out of their lane, or save a defensive skill for them.
• 7 eyes. He calls 7 eyes around him. Either 1 or 3 of them stay black. Stand in front of a black eye while the others fire poison.
• Tracking pools. Poison spawns under your feet while he stabs the platform. Keep moving until the attack ends.
• Stagger bar. Fill it, and it turns blue. He is stunned for a moment. That is your best damage window.

Belial has no loot table of his own. Open the Hoard of Belial, and you choose the table of another Lair Boss to roll from.

He also carries the highest Mythic Unique drop chance of any boss. That makes him the best target farm for a Mythic you are missing.

To chase the Melted Heart of Selig, pick Duriel’s table, since that amulet belongs to his pool. Our Selig guide covers the amulet. The Mythic Uniques guide lists the rest.

Belial joined Diablo 4 with Season 8, Belial’s Return, on 29 April 2025. The same patch split Lair Bosses into Initiate, Greater and Exalted tiers.

Superior Lair Keys arrived in Season 14. Before that, his Hoard took Betrayer’s Husks.

Season of Hell’s Legacy, the 15th season, opened with patch 3.2.1 on 15 September 2026. Belial keeps his Exalted spot in it.

A Pro group kills Belial on your account and you keep the loot.

• Torment 4. The kills run on Torment 4. A Torment 4 unlock can be added.
• Kills you pick. Choose how many kills to run on the page.
• Piloted or self-play. A Pro plays your character, or you join the group.
• Seasonal or Eternal. Softcore and Hardcore are both on the page.

Tell the chat which Mythic you are chasing.
