Diablo 4 Duriel Guide: Location, Key, Fight and Loot

Duriel, King of Maggots, is a giant grub demon you can fight as often as you like in Diablo 4. He waits at the bottom of his own lair, hits with poison and claws, digs under the floor and brings a swarm of maggots along. In return he guards Uniques for every class and a shot at Mythics.

This guide covers that repeatable lair fight: how to get there, which key pays for the loot, how to read his attacks and which items make him worth farming.

Hover over or tap an item name to see its tooltip. The cards show value ranges from the game data, so your own roll can differ.

Why farm him: his own pool of class-specific Uniques, plus for everyone.

Where to find Duriel

Duriel is a Greater Lair Boss, the middle of the three Lair Boss tiers: tougher than the Initiate bosses, easier than the top-tier fights. His lair, the Gaping Crevasse, lies at the southern edge of Kehjistan, southeast of the town of Gea Kul.

Set Torment I or higher. Lair Bosses stay locked on lower difficulties.
Discover the lair once. After your first visit the Gaping Crevasse has its own lair marker, and you can teleport straight there.
Check the map tooltip. It shows which key the Hoard takes and how many of them it needs.
Fight your way to the altar at the end of the dungeon and use it. Duriel crawls out and the fight starts.

You don't need to collect anything to summon Duriel. The altar calls him for free, as often as you like, and the key only comes into play once he is dead.

Which key you need and where to get it

When Duriel dies, a Hoard appears in his arena. The real rewards are inside, and the Hoard is personal: you open yours with your own key. In a group of four that means four keys for four Hoards, one per player.

Item	Where it comes from	What it does
Greater Lair Key	The Hoards of the Initiate Lair Bosses: Varshan, Grigoire, Lord Zir and Beast in the Ice, plus Urivar if you own Vessel of Hatred	Opens one Duriel Hoard. Andariel, The Butcher and Harbinger of Hatred take the same key.
Lair Key	Your everyday endgame, for example Helltide, World Bosses and Legion Events	Opens the Hoard of an Initiate Lair Boss, which is where Greater Lair Keys come from
Shard of Agony	Duriel himself, as his Boss Trophy	Not a key. Guides list a Horadric Cube recipe that turns 5 Shards into a random Unique from his pool.

Getting keys is a chain: Lair Keys from your usual activities open Initiate Hoards, those Hoards give you Greater Lair Keys, and the Greater keys pay for Duriel. Nobody has published how many Greater keys an Initiate Hoard gives, so count what you really have before you plan a long session.

The Horadric Cube comes with the Lord of Hatred expansion. Without it the Shards just pile up, but Duriel himself is part of the base game: you can farm him with no expansion at all.

How the Duriel fight goes

Duriel deals poison and physical damage, and the fight gets nastier the longer it lasts: more pools on the floor, more maggots, more trips underground. Blizzard doesn't publish a boss manual, so this table follows what players and guide writers describe:

Attack	How you spot it	What to do
Claw combo	Several swipes straight ahead of him	Get out of his front. A full combo can stun you.
Ground stab	The combo ends in a slam that leaves a poison pool	Step out of the pool and hit him from the side or from behind
Grab	He snatches the closest player in front of him and stabs	Stay off his front, above all in melee range. This one hurts a lot.
Charge	A short wind-up, then he rushes across the arena	As soon as he winds up, dodge sideways out of his line
Poison shots	Projectiles that leave big pools behind	Keep a clear lane to move into, so the pools can't box you in
Burrow	He digs into the ground and comes up from a new hole	Keep away from holes. Whatever comes out of one hits hard.
Maggots	Small grubs that spit poison	Kill them early, before they pile up

When he digs in

If the fight drags on, Duriel dives underground. Guides describe two tougher elite enemies showing up while he is gone. Clear them fast, because he bursts out of a fresh hole and brings a wave of maggots with him. Holes are the danger zone of this fight: maggots crawl out of them too, so never stand on one.

Don't ignore the maggots

A single maggot is harmless, but ten of them spitting poison while you dodge pools become a real threat. Some area damage or a quick sweep between two boss attacks keeps the arena clean, and then you go back to Duriel.

Use the stagger window

Like other Lair Bosses, Duriel has a stagger bar. Fill it and he is stunned for a short moment, which is the time for your biggest skills. Still, don't walk into a poison pool to finish a rotation: one more second of damage isn't worth half your life.

Before you pull him

Poison resistance first: poison is his main damage type. Armor helps against the claws and the grab, which hit physically.
Movement: keep a dash or an evade ready for the charge and for the moment he resurfaces.
Single-target damage: he is one big target, and a fast kill means fewer pools and fewer maggots.
Learn first, pay later: the fight is free. Try him on a lower Torment, then move up once his pattern feels easy.

What Duriel drops

Duriel has his own Unique pool. The first Unique from his Hoard always comes from that list, while any extra Uniques can also come from the general pool. The higher your Torment, the better the item quality. Four community loot tables for Season 15 agree on the items below:

Class	Uniques from Duriel
All classes	(chest)
Barbarian	(sword) (amulet)
Druid	(ring) Mark of the Old Wolf (ring) (boots)
Necromancer	(helm) (chest) (boots)
Paladin	No agreed entries across all four checked tables.
Rogue	(dagger) (gloves) (gloves)
Sorcerer	(ring) (ring) (staff)
Spiritborn	(amulet) (glaive)
Warlock	(flail) (helm) (gloves)

The checked tables disagree on Paladin drops, , and , so those targets stay outside the agreed list.

is the one every class can wear: it gives your Thorns a chance to hit far harder, so it shines in Thorns builds. Warlocks get , which hands Umbral Chains its Epicenter variant for free plus extra damage. Barbarians want the for a damage bonus that grows with every damaging skill on the bar, and Necromancers who play with skeletons come for and the extra minions it allows.

Mythic Uniques from Duriel

Since Season 15, a Mythic from Duriel's Hoard also comes from his own pool instead of the full Mythic list. His random side loot can still roll any Mythic. Blizzard also raised the Mythic chance of the Initiate Lair Bosses to the Greater level, so Duriel isn't automatically the best farm for every Mythic.

Blizzard hasn't published which Mythics sit in his pool or the odds per kill, so count a Mythic as a bonus. The same goes for the Smouldering Brimstone mount: Duriel can drop it as a cosmetic reward, but no kill promises it.

Farm smarter

Pick your target first. Check that the item is in his pool above. If it isn't, another boss is the better farm.
Count your keys before you go. Each kill you want to loot costs one Greater Lair Key, and the map tooltip reminds you which key the Hoard takes.
Fast kills beat high Torment. A Torment you clear without deaths gives more Hoards per hour than one where you keep failing.
Group only with damage. Every player pays for their own Hoard, and guides say Duriel scales with the group. A party pays off when everyone brings real damage.
Keep the Shards. They stack up while you farm, and the Cube recipe gives them a use once you own Lord of Hatred.

Quick plan for a Duriel farm

Collect Lair Keys from Helltide, World Bosses and Legion Events, then earn Greater Lair Keys from the Initiate bosses.
Check your build for poison resistance, decent armor, a free movement skill and strong single-target damage.
Teleport to the Gaping Crevasse from the map, on a Torment you clear without deaths.
In the fight, stay off his front, leave every pool at once, keep away from holes and clear the maggots early.
Open your Hoard with one Greater Lair Key and read every Unique.
Use the altar again while your keys last, and step up a Torment once the kills feel easy.

Conclusion

Duriel is a fair farm: the fight is free, one Greater Lair Key opens your Hoard, and his pool tells you which Uniques you are playing for. Learn his front attacks and the burrow on a low Torment, and keep the key chain running through the Initiate bosses.

FAQ

Where is Duriel in Diablo 4?

In the Gaping Crevasse in southern Kehjistan, southeast of Gea Kul. After your first visit you can teleport there from the map. The altar at the end of the dungeon starts the fight.

How do I summon Duriel?

Use the altar at the end of the Gaping Crevasse on Torment I or higher. The fight costs nothing and you can repeat it as often as you like. You only spend a key on the Hoard after he dies.

What key do I need for Duriel?

One Greater Lair Key opens your Hoard after the kill. In a group every player needs their own, because each player opens a personal Hoard.

Where do I get Greater Lair Keys?

From the Hoards of the Initiate Lair Bosses: Varshan, Grigoire, Lord Zir, Beast in the Ice and, with Vessel of Hatred, Urivar. Those Hoards open with a regular Lair Key from your everyday endgame, such as Helltide, World Bosses and Legion Events.

What does Duriel drop?

Uniques from his own pool: Razorplate for every class and, for most classes, two or three class items, for example Scourge of Duriel for Warlocks and The Undercrown for Necromancers. The loot tables disagree on Paladin. Higher Torment gives better item quality.

Does Duriel drop Mythic Uniques?

He can. Since Season 15 a Mythic from his Hoard comes from his own pool, and his random side loot can still roll any Mythic. Blizzard hasn't published which Mythics are in his pool or the odds, so no kill guarantees one.

What are Shards of Agony for?

They are Duriel's Boss Trophy, not a key. Guides list a Horadric Cube recipe that turns 5 Shards into a random Unique from his pool. The Cube needs the Lord of Hatred expansion.

Can Duriel drop a mount?

Yes, the Smouldering Brimstone mount is one of his cosmetic rewards. It can drop, but no kill guarantees it.
