Nightmare Dungeons are one of the best late-game activities in Diablo 4, and there is more than one difficulty for them beyond the World Tiers. Our guide will cover all the tiers and how you can access them.

What are Nightmare Dungeon Tiers in Diablo 4?

There are100 Nightmare Dungeon Tiers in Diablo 4 that all have randomized Affixes and rewardsfor players to collect. To reach higher Tiers, you need to bring Sigil Powder to the Occultist and increase the level of your Sigils. Below you may find all the tiers and the amount of powder needed for each level.

Tier 1 to 20 can be done in the Diablo 4World Tier 3setting, but anything after is only available inWorld Tier 4and is considered Ancestral. The affixes also get shot up to five per dungeon once you enter the World Tier 4 territory. Getting there is going to take some time though.

Diablo Season 1 Nightmare Dungeons

Dungeon Tiers were adjusted in Diablo 4’s first season. If you played the Tiers at level 70 or higher in the past, then you probably found them much easier going forward. Sigils that were at level 100 felt more like level 70 tiers before Season 1. Season 1 also increased the drop rate of items, rewarding you with more items of higher rarity. And those high-level dungeons will likely see more changes as times goes on.

Diablo Season 2 Nightmare Dungeons

For season 2, the layout of Diablo 4’s Nightmare Dungeons have been heavily revised to allow for easier navigation and less backtracking. Objectives have been removed for a handful of dungeons, only requiring you to defeat the boss, and existing objectives have been placed on the main path to prevent the need for backtracking. Nightmare Dungeons are also now more procedurally generated to make them feel less repetitive, and you can teleport directly to the inside of them to reduce load times.

In addition to layout changes, Diablo 4’s Season 2 Nightmare Dungeons have increased enemy density that provide better XP yield. You’ll also now get Nightmare Sigils upon completion of a dungeon.

What are Diablo 4 Nightmare Sigils?

Nightmare Sigils in Diablo 4 serve as a key of sorts to Nightmare Dungeons. Each one corresponds to a specific dungeon in the game, and consuming a sigil will temporarily turn its corresponding dungeon into a Nightmare Dungeon.

Nightmare Sigils come in varying tiers, dictating the difficulty of the Nightmare Dungeon its attached to. Different tiers will have different affixes both positive and negative and will change the toughness and amount of monsters you encounter. Monster levels will also scale with each tier, increasing by +1 for every tier, starting at a minimum monster level of 54 at tier 1 to a maximum level 154 at tier 100.

How to Get Nightmare Sigils

There arefive ways to get Nightmare Sigilsin Diablo 4:

You will unlock sigil crafting after completing your first Tier 3 Nightmare Dungeon. To get higher-tier Nightmare Sigils in Diablo 4, you’ll need to craft them using plenty of powder, which you’re able to get by salvaging your unwanted lower-tier sigils.

You’ll get your first Nightmare Sigil in Diablo 4 after completing the main questline and the Cathedral of Light Capstone Dungeon in Veteran difficulty. After silencing10 Whispers in Nightmare difficulty, return to the Tree of Whispers, and you’ll be rewarded with a cache that contains a Nightmare Sigil. Whispers of the Dead (temporary requests from the Tree of Whispers indicated by an icon on the map) will commonly reward you with sigils, and this will likely be your primary way of receiving them.
