Looking for Nightmare Dungeons in Diablo 4 Season 1? In Diablo 4, there are a lot of activities to do in the world of Sanctuary. One of the newer ones added to the game are the Diablo 4 Nightmare Dungeons. These were slated by the developers as one of the main endgame systems that players would interact with.

You might be wondering how to make the best endgame build for Diablo 4, or looking at the best class to choose. But how do you unlock these endgame Nightmare Dungeons, and are they even worth running? Well, strap in, as we’ll cover those questions and more in our Diablo 4 Nightmare Dungeons guide.

Diablo 4 nightmare dungeons will require the correct sigil to unlock

How do you unlock Nightmare Dungeons in Diablo 4?

Here’s how to unlock Nightmare Dungeons:

  • Complete the campaign
  • Complete the Capstone dungeon
  • Open World Tier 3 
  • Find a Nightmare Dungeon sigil
  • Use the sigil to turn any dungeon into its Nightmare version

Unlocking nightmare dungeons in Diablo 4 is actually quite easy. There are a couple of requirements that you’ll have to fulfill. First, you’ll have to beat the campaign. Then you’ll have to complete your capstone dungeon to unlock World Tier 3. Once you’re in World Tier 3, you’ll have to find a Nightmare Dungeon sigil.

The easiest way to find these is to do a full Whispers of the Dead run. Upon talking to the Tree of Whispers and opening your cache, you’ll be rewarded with a sigil to a random tier-one nightmare dungeon. Clicking on the sigil in your inventory will turn that dungeon into a nightmare dungeon until you complete it, leave the game, or open a new sigil. Then you can click on the dungeon on your map to teleport to the entrance.

World tier 3 will drop tiers 1-20 of nightmare dungeon sigils, while world tier 4 will drop tier 21-100. These increase in monster level and affix difficulty. You will also eventually unlock the ability to craft sigils with the occultist in town.

How do you complete Nightmare Dungeons?

Completing nightmare dungeons is also pretty straightforward. Once you enter the dungeon, you’ll want to progress through the dungeon as you would normally. There is a set of objectives that you’ll have to complete on the right side of your screen. These will be different for each dungeon. You’ll know when the dungeon is completed when a large immunity bubble pops up around your character with a pedestal in the middle to upgrade your glyphs.

Outside of the loot that you’ll pick up along the way, each nightmare dungeon has random rewards that you’ll earn at the end. You’ll earn a random legendary item, which also has a chance to be a Unique item. You’ll also earn a level-appropriate sacred or ancestral rare item. Once the dungeon is complete, you’ll also be awarded the experience to upgrade glyphs that you put in your paragon board.
