Belial, the cunning Lord of Lies, has returned to torment Sanctuary in Diablo 4's Season 8 update. Unlike previous seasons that required materials or special conditions to summon major bosses, Belial now awaits players bold enough to face him head-on. This guide covers everything from how to summon him to how to survive his deceptive onslaught and claim his loot.

How to Summon Belial in Season 8

With Season 8, Blizzard streamlined the summoning process for endgame hideout bosses:

No Summoning Materials Needed: You no longer require specific crafting materials or rituals. Simply travel to the designated location and begin the encounter.

Travel to His Lair: Belial can be summoned inside the Palace of the Deceiver, located west of Tarsarak in the Kehjistan region.

World Tier Requirement: You must be in Torment difficulty (World Tier 4) to access the dungeon and summon Belial.

Start the Fight: Interact with the Altar of Lies inside the palace to trigger the boss battle.

Belial's Difficulty Level Explained

Since Season 6, Blizzard has removed traditional World Levels and introduced a dynamic difficulty scaling system. This means:

Belial's level scales with your current difficulty tier.

The monsters inside the Palace of the Deceiver will match your power level.

You won't see enemy levels anymore, so your preparation matters more than ever.

Defeating Belial: Pre-Fight Preparation

1. Bring a Strong Build

To stand a chance, use one of the top-tier endgame builds for your class. These are typically optimized around high DPS, sustain, and mobility. For Season 8, check out updated class tier lists to select the right setup. Belial hits hard, and the faster you burn him down, the safer you'll be.

2. Maximize Your Resistance

Belial's damage type focuses heavily on:

Poison

Shadow

Ensure your Poison and Shadow Resistance are at least 70%. If your gear falls short:

Use resistance potions.

Craft and activate incense for bonus temporary resistances.

Equip legendary aspects that mitigate poison or shadow damage.

Understanding Belial's Attack Patterns

The Belial fight is unique compared to traditional bosses. Here's what to expect:

Arena Layout

You fight on a platform, while Belial himself remains stationary behind it.

You cannot move behind Belial, which changes dodging dynamics.

Your movement is limited to the front-facing semicircular space.

Belial's Attacks

Ground Slam & Swipe

Belial slams his fist down, then drags it across the platform.

This causes knockback and heavy AoE damage.

Avoid by moving to the far side of the platform or using a teleport/dash ability.

Sweeping Beam

He fires a wide shadow beam across the platform.

The beam moves horizontally-teleport or reposition quickly to the opposite side.

Poison Puddles

Periodically, toxic pools appear under your feet.

Standing in these will rapidly drain your health. Move constantly and avoid static positioning.

Poison Waves

Puddles emit waves of poison-dodge these as they radiate outward.

Summoned Eyes

Floating eyes appear and shoot projectiles.

Position yourself so that no eye is directly facing you to reduce incoming damage.

Tips to Survive the Fight

Mobility is key: Don't stand still for too long. Constantly reposition yourself to avoid overlapping attacks.

Control adds: While Belial doesn't summon traditional mobs, the eyes and environmental hazards require crowd control or evasive skills.

Use cooldowns wisely: Time your defensive skills during his swipe or beam phases.

Group advantage: If you're in a group, assign someone to call out incoming attacks and beams.

Post-Fight Rewards: How Loot Works

After you defeat Belial:

A loot chest will appear.

To open it, you'll need 2 Cloaks of the Traitor, which can be obtained from:

Belial's random appearances after defeating other bosses.

Weekly seasonal activities or event completions.

Unique Loot Mechanic: Belial offers player-selected loot. Upon opening the chest, you can choose your reward from several powerful item options, similar to the weekly cache system from Tree of Whispers.

This makes farming Belial highly rewarding, especially for min-maxing your gear.

Final Thoughts

Belial offers a challenging and visually stunning boss fight in Diablo 4's evolving endgame. The fight demands solid build preparation, resistance management, and mechanical skill. Thanks to Blizzard's updates, summoning Belial is now straightforward, allowing players to engage with high-end content more frequently.
