Belial can be found in the Palace of the Deceiver, a dungeon situated in the Amber Sands zone of northern Kehjistan. To locate it more easily, look just west of the Tarsarak Waypoint. This dungeon becomes accessible only when playing on Torment difficulty or higher, so ensure you're prepared for a challenging encounter before you head in.

The Amber Sands region is harsh and dangerous, full of cursed terrain and powerful enemies. The entrance to the dungeon lies hidden among ancient, ruined stone structures along the cliffside. It's easy to miss if you’re not actively searching, so scan the terrain carefully near the cliffs to find the passageway that leads into the Palace of the Deceiver. Once discovered, you can fast-travel directly to its entrance for future attempts.

How to Summon Belial

To face Belial in Diablo 4, head to the Palace of the Deceiver, located in the Amber Sands subzone of northern Kehjistan, just west of the Tarsarak Waypoint. Once discovered, you can fast-travel directly to the dungeon entrance. Belial is only available on Torment difficulty, so make sure your build and gear are prepared before entering.

Unlike other bosses in Diablo 4, Belial doesn’t require any summoning materials to initiate the fight. You simply need to reach the altar inside the Palace of the Deceiver. However, to access Belial’s reward chest after the battle, you’ll need either 2 Betrayer’s Husks or Lair Keys — both are used to unlock the “Belial’s Hoard” chest at the end.

Betrayer’s Husks can only be obtained by defeating Mini Belial, an ambush encounter that randomly appears after fighting other Greater Lair Bosses like Duriel or Andariel. These husks are essential if you want to claim Belial’s most valuable rewards, including a guaranteed Ancestral Unique and a high chance of obtaining Diablo 4 Belial Boss.

Belial Boss Mechanics

Belial is a deceptive and deadly boss in Diablo 4, known for his lethal combinations of Poison and Physical damage. His attacks can quickly overwhelm unprepared players, so having gear with proper resistances is key to survival. Belial also features a Stagger Bar mechanic, which creates powerful openings when filled. Below are his most dangerous mechanics you need to watch out for:

✅ Stagger Bar: Filling the stagger bar stuns Belial temporarily, giving you a short window to deal maximum burst damage. Use this wisely to recover the momentum of the fight.
✅ Tight Arena: The fight takes place in a small, circular area with limited movement space. Positioning and movement awareness are critical to avoid deadly combos and being cornered.
✅ Stacking Poison Damage: Belial applies poison effects quickly, and they stack over time. Without Poison Resistance gear or elixirs, your health can drain before you realize it.

Learning Belial’s movement and attack patterns is crucial to success. His combos are often telegraphed, but punishing if ignored. Stay on the move, use resistance boosts, and keep your cooldowns ready for recovery and disengage moments. One mistake can lead to a quick wipe, so treat this fight with respect.

Belial Abilities

Belial combines poison and physical damage in a deadly blend of area denial, burst attacks, and punishing mechanics. His abilities force constant movement and strong awareness. Below is a breakdown of his main abilities:

Ability	Description
Claw Swipe	Belial swipes the ground with his massive claws, hitting a wide arc on the upper platform. Stay at the lower edge of the arena to avoid the strike.
Poison Spit	Belial spits a beam of poison in a straight line. The attack leaves behind poison puddles that restrict movement. Position yourself on the opposite side quickly.
Poison Wave	Waves of poison slide across the arena floor. They often come in multiples, requiring precise movement and quick dodges to avoid splash zones.
Betrayer’s Eyes	Floating orbs appear around the arena. Only the black/dim one is safe. Standing in front of other colored orbs causes massive damage as they fire poison beams.
Tracking Pools	Poison pools appear under players and track them as Belial stabs the ground. Keep moving in wide circles until the pools disappear.

Belial also uses illusions and traps to confuse players. Most attacks cover large zones of the platform, so fast repositioning and preemptive dodges are key to survival.

Belial Ambush Encounter Abilities

After defeating a Lair Boss, Belial may ambush you with a chaotic fight featuring unique mechanics. These abilities blend poison, illusions, and blood magic.

Belial Ambush Encounter Abilities

Ambush Ability	Description
Poison Wave	Marks a wide zone and releases a poison blast after a short delay. Move out immediately to avoid heavy AoE damage.
Poison Pools	Puddles grow in size before exploding. Dodge out before they expand to avoid poison splash and DoT effects.
Poison Projectiles	Illusions of Belial fire projectiles in crisscrossing patterns. Constant movement is key to avoid being hit.
Black Soulstones	Explode after a delay. Watch where they land and reposition quickly to avoid radius damage.
Belial Illusions	Mini Belials spawn in red rings and use poison attacks. Kite and destroy them before you get surrounded.
Chained Black Soulstones	Soulstones chase players until detonation. Use speed skills and crowd control to manage safely.
Aerial Blood Attack	Blood spears rain from above, targeting zones. Dash out between waves to avoid layered damage.
Add Spawn	Snake-like elite adds appear and deal stacking poison damage. Focus them quickly to maintain control of the arena.

These ambushes are fast, brutal, and require perfect movement. Be prepared to respond instantly to area effects and illusions while keeping your distance from Belial’s traps.

How to Beat Belial Diablo 4

Belial is a mechanically rich boss fight filled with hazards, ambush phases, and poison damage. To defeat him without constant wipes, you'll need a clear strategy, the right build, and solid reactions. Use Poison Resistance Elixirs to survive the stacking damage, and equip high single-target burst skills for efficient phases.

Positioning is crucial — avoid clustering near allies and stick to the platform edges where tracking pools and projectiles are easier to dodge. When illusions appear, don’t waste time. Focus your damage on the real Belial and reposition to avoid incoming attacks.

Use cooldowns wisely — especially during Stagger windows when Belial is vulnerable. If snake-like adds spawn, eliminate them immediately before they start overlapping with boss mechanics.

Tip	Description
Use Poison Resistance Elixirs	Greatly reduces incoming poison damage during long phases
Focus on Mobility Builds	Helps avoid poison pools, projectiles, and soulstone explosions
Save Cooldowns for Stagger	Use your biggest damage skills when Belial is stunned
Don’t Attack Illusions	Focus all damage on the real boss, not distractions
Clear Adds Fast	Prevent overlap during ambush by killing snake adds early

Mastering Belial's patterns and adjusting your gear is the key to success. Experiment with builds, watch your movement, and commit to learning the encounter — it’s one of the most challenging and rewarding fights in Diablo 4.
