Diablo 4 Echo of Duriel (Tormented Duriel) In-depth guide. How to get the best gear in D4 - Mythic unique items

This guide provides comprehensive information on unlocking and summoning Tormented Duriel, a key endgame boss in Diablo 4 Season 8 Season of Belial's Return. It details how to acquire the best gear, including Mythic unique items exclusive to this boss, along with an updated loot table showing increased probabilities for these rare items.

Tormented Duriel Location in Diablo 4

To locate the Echo of Duriel boss in the latest Diablo 4 season, you need to set your game difficulty to Torment 1. Head southeast from Kehjistan's capital city, Gea Kul, and look for the level 100 dungeon "Gaping Crevasse." Within this dungeon lies the Pestilent Altar, the site required to summon and confront Echo of Duriel.

How to Summon Diablo IV Echo of Duriel

Upon entering the dungeon, players will encounter fanatical followers of Tormented Duriel. The Pestilent Altar, required for summoning, is located at the dungeon's end in an area called The World's Bubo.

Upon entering the dungeon, players will encounter fanatical followers of Tormented Duriel. The Pestilent Altar, required for summoning, is located at the dungeon's end in an area called The World's Bubo. To initiate the Ritual of Agony and summon Duriel, the following materials are required: x2 Mucus-Slick Egg and x2 Shard of Agony.

Transmutation Details: At any Alchemist station, players can use extra materials like Living Steel, Exquisite Blood, or Grigoire Fragments to transmute them into summoning items. Open the “Refine Resources” tab and look for recipes related to Mucus-Slick Eggs or Shards of Agony.

This mechanic is perfect for solo players or those farming bosses inefficiently. It removes the need to repeatedly farm Varshan or Grigoire directly.

Pre-Fight Preparation

• Bring Elixirs: Poison Resistance + Critical Strike Elixirs work well together.
• Craft Incense: Use incenses that boost Armor, Max HP, or DoT resistance.
• Team Composition: Include 1 ranged DPS and 1 support with healing or CC.

Where can I get materials for summoning Tormented Duriel in D4?

Mucus slick eggs - you are guaranteed to get one for killing Echo of Varshan on Torment 1.

Important: Only one who uses reagents for Varshan summoning will get Mucus slick eggs.

To summon Varshan himself, you need to collect only x4 Malignant Heart

You can obtain heart from cache rewards from The Tree of Whispers, killing Elite monsters, World Bosses, completing Undercity of Kurast, bartering at the Mercenary Den.

Shard of Agony - you get one for killing Grigoire, the Galvanic Saint on Torment 1. To summon him, you will need x12 Living Steel. You can obtain them from cache rewards from The Tree of Whispers, killing Elite monsters, World Bosses, opening Tortured Gifts in Helltide, completing Undercity of Kurast, bartering at the Mercenary Den

Another way to obtain materials for summoning the boss is to transmute materials used to summon Tormented Varshan and Tormented Grigoire, as well as materials from other bosses. This can be done at the Alchemist using the following recipes:

Mucus-Slick Egg

• x5 Khazra Horn
• x9 Malignant Heart
• x4 Abstruse Sigil
• x15 Veiled Crystal

Shard of Agony

• x5 Khazra Horn
• x9 Living Steel
• x4 Abstruse Sigil
• x15 Veiled Crystal

Another way is to buy our Diablo 4 Duriel summoning sets service and save tons of time on a materials grind

Transmutation of Summoning Materials

You can transform materials used for summoning other bosses into Mucus-Slick Egg and Shard of Agony at the Alchemist. This approach provides an efficient way to repurpose your resources for the fight against Tormented Duriel. Here are the recipes needed for each item:

Transmute Mucus-Slick Egg

• 5 Khazra Horn
• 9 Malignant Heart
• 4 Abstruse Sigil
• 15 Veiled Crystal

Transmute Shard of Agony

• 5 Khazra Horn
• 9 Living Steel
• 4 Abstruse Sigil
• 15 Veiled Crystal

This transmutation option is especially useful for players looking to save time and streamline their preparation for this challenging encounter.

How to Beat Diablo 4 Tormented Echo of Duriel

Finally, all the materials for the ritual are gathered, and now we can fight the boss. The battle will be difficult, as this is the second most difficult boss after Echo of Lilith. Before you press the desired Summon button, I recommend you check again if you are ready for the fight:

1. The boss is designed for level 50+ players (if you haven't reached it yet, you can use our Diablo 4 Power leveling boost to speed up the process).
2. It is advisable to have 70% Poison resistance and a supply of Potent Elixir of Poison Resistance.
3. A strong solo target build that can survive. It's recommended to have more than 7000 armor.
4. Know the abilities of Tormented Duriel and the phases of the fight, which I will write about below.

Abilities of Echo of Duriel

• Claw slash: Tormented Duriel makes a series of attacks in front of him, followed by a powerful ground strike, leaving a poison pool that damages anyone in it.
• Poison pool: Occasionally, the boss releases poisonous spits that leave behind poison pools upon impact.
• Charge: Duriel, Maggot King makes a dash towards the player, knocking them back and dealing significant damage on impact.
• Devouring: Duriel can grab the player and start devouring them, making them immobile and dealing multiple damage.
• Burrowing: The boss burrows underground and appears in one of the holes in the ground.
• Maggots: Several times during the fight, Tormented Duriel will summon Pang of Duriel - minions with low health but actively spit poisonous, painful attacks.

Phase 1

The ritual is initiated, the camera mysteriously moves back, and we begin the fight.

The battle starts with three marks visible on the ground. In the areas marked with orange circles, Pangs of Duriel — large maggot-like enemies — will spawn. They don’t have much health but can stack poison damage rapidly. Focus them down early.

Duriel’s attacks in this phase include:

• Claw Slash: A frontal cone melee attack with moderate damage and knockback.
• Poison Pool: Creates toxic puddles on the ground that deal stacking damage over time. Avoid standing in them even with poison resistance.
• Charge: A straight-line dash toward a target. Easy to dodge with positioning.
• Devour: A powerful bite aimed at the closest target. Interrupt or kite when possible.
• Burrow: Duriel submerges underground and reappears beneath or near players, dealing AoE damage.

Key strategies:

• Don't stand still — reposition constantly to avoid poison zones and direct attacks.
• Take down maggots quickly, especially if you don't have capped poison resistance.

Phase 2. 50% D4 Echo of Duriel

At 50% health, Duriel will burrow again and enter a heightened state of aggression. He spawns a second wave of Pangs of Duriel, and after about 10–15 seconds, he’ll begin actively using his Poison AoE abilities at a faster rate.

New mechanics introduced in this phase:

• Toxic Maggot Rain: Duriel summons poisonous projectiles from above in wide waves. These inflict stacking poison and demand constant movement.
• Poison Explosion: When maggots die, they now leave behind poison pools. This forces you to spread out add kills and avoid clustering.
• Phase Shift: Duriel becomes semi-transparent and significantly faster. His cast animations shorten, making it harder to dodge major attacks.
• Burrow Frenzy: He begins chaining burrow attacks unpredictably, making melee positioning riskier.

Important: Phase 2 adds more pressure and less safe space. Save your major cooldowns and elixirs for this stage, and always rotate away from overlapping poison zones.

Note: This updated phase behavior reflects changes added in Season 7. Older versions of the fight had simpler attack patterns; current encounters are more punishing and chaotic.
