What are Nightmare Dungeons in Diablo 4?

Nightmare Dungeons in Diablo 4 are modified variants of existing Dungeons, packed with extra rewards for endgame players. You need to be at World Tier 3 to unlock them so finish the Cathedral of Light Capstone Dungeon at World Tier 2 first.

Diablo 4 Nightmare Dungeons are unlocked by Nightmare Sigils that transform a Dungeon by adding extra modifiers. Nightmare Dungeons come in various difficulties and feature unique modifiers, determined by the Nightmare Sigil used to open them. They can be tiring to complete without the right set of gear and skills.

What are Nightmare Sigils in Diablo 4?

Nightmare Sigils are keys that are used to unlock Nightmare Dungeons in Diablo 4. There are three primary ways to find Nightmare Sigils:

1. Competing Whispers of the Dead tasks.
2. Finding them during a Nightmare Dungeon attempt.
3. Craft Nightmare Sigils at an Occultist with Gold and Sigil Powder (obtained from salvaging Sigils)

In addition to the three ways mentioned above, you can also get Nightmare Sigils from challenging world events but you’re better off trying the above steps to get them. Your set difficulty determines the max tier of Nightmare Sigils that you can access.

Best Nightmare Dungeons in Diablo 4 Season 1 for farming XP

Here’s a tier list of the best Nightmare Dungeons for XP in Diablo 4 Season 1:

Tier in Diablo 4	Nightmare Dungeons
S-Tier	Dead Man’s Dredge, Mercy’s Reach, Sarat’s Lair, Uldur’s Cave
A-Tier	Hoarfrost Demise, Komdor Temple, Nostrava Deepwood, Pallid Delve, Tomb of the Saints
B-Tier	Ancient Reservoir, Akhan’s Grasp, Charnel House, Garan Hold, Immortal Emanation, Kor Valar Ramparts, Mariner’s Refuge, Stockades
C-Tier	Bastion of Faith, Betrayer’s Row, Collapsed Vault, Domhainne Tunnels, Faceless Shrine, Forgotten Ruins, Halls of the Damned, Heretics Asylum, Iron Hold, Lost Keep, Path of the Blind, Shifting City, Twisted Hollow.

This tier list prioritizes Nightmare Dungeons where you don’t have to backtrack often. What this means is that you’ll spend less time in an S-tier dungeon, making for an effective use of your time. High enemy mob density is another sweet bonus. While it’s worth clearing the A-tier and B-tier ones, we’d suggest avoiding the rest.

Nightmare Sigil Tiers in Diablo 4

On World Tier 3: Nightmare difficulty, you’ll have access to Sacred Tier 1-20 Nightmare Sigils. World Tier 4: Torment difficulty lets you use Ancestral Tier 21-100 Nightmare Sigils. Tiers determine the level of the monsters you face (50 + World Tier 3/4 + Nightmare Sigil Tier) and your rewards.

You need to manually activate a Nightmare Sigil before heading to the specific Dungeon, now converted into a Nightmare Dungeon with Affixes (extra modifiers). Tiers 11 and above feature four dungeon Affixes instead of three and Tiers 21 and above raise it to five Affixes. Positive Nightmare dungeon affixes like bonus lightning damage exist too. Tier 21 Nightmare Dungeons and above also restrict your revives to four (down from 12) before you fail a run and get locked out.

Nightmare Dungeon afflictions are not necessarily negative and some even help the player like boosts to certain types of damage. Use the right Diablo 4 gems to counter elemental attacks. While higher tiers can get frustrating, Nightmare Dungeons are worth the trouble. Higher Nightmare Dungeon tiers grant more Glyph XP that can be used to upgrade Paragon Glyphs socketed in your Paragon Board. They also grant Legendary and Unique loot, coin, and heaps of XP.

While there are over a hundred dungeons in Diablo 4, only a few of them are designated as Nightmare Dungeons. Accessible by Ancestral Sigils and Sacred Sigils, these are scattered across the game’s five regions: Fractured Peaks, Dry Steppes, Hawezar, Kehjistan, and Scosglen. The developer stated that this will change over time so keep your eyes open for new Nightmare Dungeons for special modifiers and fresh loot drops.
