Belial, a classic Diablo boss, returns in Diablo 4 Season 8. This demon of lies has three forms in Diablo 4: Apparition, “Mini” Belial and “Uber” Belial.
Like Uber Lilith, Uber Belial will be the most hard fight in Diablo 4. To get Belial’s boss powers, you must defeat him first. Here’s how to deal with Belial.
How To Summon Belial?

There are three different Belial in the game that appear in three different ways.
- Apparition Belial: After defeating the first two bosses in Apparition Incursion, the last boss is Belial.
- Mini Belial: When you defeat Lair boss, maybe Belial’s Ambush will be triggered. Mini Belial will appear and attack you.
- Uber Belial: Uber Belial requires no summoning materials, but you will need 2 Betrayer’s Husks to open its chest, and Betrayer’s Husks are dropped by Mini Belial.
Once you have enough Betrayer’s Husks, you can go to the dungeon in Palace of the Deceiver in Kehjistan to summon Uber Belial.
How To Prepare?
Adjust Your Build
Uber Belial does not rely on summons, and will frequently use various skills to affect your movement range. Therefore, you can use some Diablo 4 Gold to re-select your skills to ensure that your build can deal damage to a single boss while also ensuring that you have enough survivability.
Poison Resistance
Many of Uber Belial’s skills deal lots of poison damage. If you have a high poison resistance, this fight will not be that difficult. You can use Elixir of Poison Resistance II to increase your poison resistance.
Required Crafting Materials:
- Bundled Herbs x 40
- Emerald Fragment x 300
- Angelbreath x 30
- 6000 Diablo 4 Gold
Belial’s Skills
Belial deals mostly poison and physical damage, so you’ll want to maximize your armor and poison resistance. Belial has a Stagger Bar, and when you fill it up during a fight, Belial will turn blue and be briefly stunned, which is a great time to lean in on your damage.
Uber Belial
Belial has a few attacks to watch out for:
- Claw Sweep: Belial stabs into the platform with one claw, then sweeps across it. Avoid standing on top of the platform to avoid this attack, and positioning is the key to avoid.
- Poison Spray: Belial sprays poison from one end of the platform to the other. You need to stand in front of the black eyes to avoid damage, and all other eyes will cast deadly venom all over the platform.
- Poison Wave: The pools of poison slide across the platform from left to right. If multiple pools of poison appear, use defensive skills or potions and stay out of their path.
- Belial’s Eyes of Betrayal: Belial summons seven eyes around himself. One to three of the eyes will turn black/inactive. Stand in front of the black eyes to avoid damage. All other eyes will cast deadly poison all over the platform.
- Poison Pools (Tracking): Belial will stab the platform with his claws and create poison pools at your feet. These pools will track your position, so you need to keep moving and be careful to avoid the pools that form until the attack is over.
Mini Belial
Mini Belial deals the same type of damage as Uber Belial, but it appears after you defeat Lair Boss, leaving the player with little time to prepare, but it is easy to deal with if you know his skills.
- Poison Wave: Belial marks a rectangular area in front of him and releases a poison wave that sweeps across the entire platform. Stay away from the area before the wave hits to avoid being hit hard.
- Poison Pools: Large poison pools will spawn near Belial and explode. Keep moving and avoid these areas when poison pools appear.
- Poison Bombs: A phantom of Belial appears, firing poison bombs into the arena. Keep dodging to avoid getting knocked out by the crossfire.
- Black Soulstone: Three or more Soulstones spawn and explode shortly after. Watch their positions and keep your distance before they explode.
- Belial Illusion: Three mini versions of Belial appear in a red circle. Once activated, they release poison waves and trigger other mechanics. Avoid the center and keep moving until the circle disappears.
- Connected Black Soulstones: One or two Soulstones connect directly to Belial and begin tracking you, and they will follow you until they explode. Keep your distance and use evasive skills to avoid getting trapped.
- Blood Strike from the Air: Blood spears drop from the air in a random pattern, and you need to pay attention to the red signs on the ground and hurry.
- Adds Spawns: Elite snake-like adds will join the fight when ambushed. Focus on them quickly to avoid being overwhelmed, especially in high-density mechanics.
Loot Pool
Belial has no fixed loot pool, but after defeating him and opening Belial’s treasure with Betrayer’s Husk, you can choose the loot pool of other lair bosses as the drop pool for this boss battle, which will help you get the items you want better.
In addition to the regular drops such as gold, materials, etc., the first unique item dropped will definitely come from the boss-specific loot table you choose. Any additional unique drops have a 50% chance to come from the public drop pool. You also have a chance to get an Ancestral Unique Item from Belial’s drops.
If you are playing in a group, each other player will increase the chance of dropping an additional unique item by one third.
These are some attacks of the new boss Belial in Diablo 4 Season 8. I hope it can help you get Boss Powers or other rewards you want.
