Learn how to activate, clear, and benefit from Diablo IV's Nightmare Dungeons. Discover sigils, affixes, difficulty tiers, and Paragon Glyph XP rewards.
Nightmare Dungeons in Diablo 4 are standard Dungeons that have been amplified by a Nightmare Sigil. This sigil increases enemy difficulty and rewards, making them a lucrative endgame activity. The sigil dictates the specific Dungeon, its difficulty Tier (1-100, with 21+ in World Tier 4), the number of allowed Revives, and active Dungeon Affixes.
Higher Tiers mean tougher enemies and rarer, more potent loot. Clearing these dungeons also grants Sigil Dust (for crafting sigils), more Nightmare Sigils, and allows you to upgrade Paragon Glyphs.
To activate a Nightmare Dungeon, use a Nightmare Sigil from your inventory's “Consumables” tab. The affected Dungeon's icon on the map will change to a red-and-white Nightmare Dungeon icon, displaying its stats when hovered over.
The gameplay within a Nightmare Dungeon is similar to a regular Dungeon: complete objectives, which usually involve killing enemies or finding items to progress. Often, you'll face a Dungeon Boss at the end. Random Events can still occur.
While more rewarding than Helltide Events, Nightmare Dungeons are less casual due to sigil requirements and the risk of failure. They revitalize Dungeons and encourage repeated runs for better loot.
Nightmare Dungeon Difficulty Tiers
The difficulty Tier of a Nightmare Dungeon is set by its activating Nightmare Sigil. Sigils found in World Tier 3 typically yield Tier 1-5 sigils. Higher Tier sigils can be crafted at the Occultist using Sigil Dust, which is found within Nightmare Dungeons or by salvaging unwanted sigils.
The Dungeon's Tier directly impacts enemy power and the quality of loot, including XP for Paragon Glyphs.
Nightmare Dungeon Dungeon Affixes
Each Nightmare Dungeon features several Dungeon Affixes—random properties that can be beneficial or detrimental. Negative affixes observed include enemy-spawning portals, monster enraging mechanics, elemental damage on attacks, Elite affixes like “Suppressor” or “Thunder Lance,” and a “Drifting Shade” that pursues players.
The number and type of affixes are determined by the sigil, with higher Tier Dungeons generally having more affixes (typically 3-5).
Earning Paragon Glyph XP in Nightmare Dungeons
Completing a Nightmare Dungeon rewards you with an Upgrade Glyph. Interacting with this allows you to assign XP to your Paragon Glyphs. Leveling up Glyphs increases their bonuses and can expand their Radius, potentially enhancing nodes within or unlocking new bonuses. Higher-level Glyphs require more XP.
How to Do Nightmare Dungeon Runs in Diablo 4
To create a Nightmare Dungeon, you need a Nightmare Sigil, which can be obtained from:
- Tree of Whispers Rewards
- Legion Events
- World Bosses
- Clearing Nightmare Dungeons
Each sigil transforms a random Dungeon into a Nightmare Dungeon. Clearing them involves completing a series of objectives, similar to normal Dungeons, often culminating in a boss fight. The objectives and layout remain the same as the Dungeon's normal variant.
