Prepare to delve into the darkness like never before in Diablo 4’s Nightmare Dungeons. Players eagerly await the chilling challenges in this end-game activity — but what should they expect? 

Nightmare Dungeons promise to push the boundaries of fear, testing the skills and grit of even the most potent builds & characters. In this article, we will explore the haunting depths of Diablo 4’s Nightmare Dungeons, uncovering the twisted horrors that lie within and the rewards that await those brave enough to face them.

These are unique, demanding, and bountiful variations of the standard Dungeons in Diablo 4. For those facing obstacles navigating through Nightmare Dungeons, consider seeking a D4 boost to enhance your game performance.

Why should you play Nightmare Dungeons in D4?

You can open Nightmare Dungeons through special keys corresponding to a specific Sanctuary location. The focus would be to level up your Glyphs that can be used in your Paragon Board to enhance your character’s capabilities further.

Nightmare dungeons have additional difficulty scaling and extra afflictions that make them harder to finish, but the layout, monsters & objectives will be the same.

How to unlock Nightmare Dungeons in Diablo IV

Types of Dungeons in Diablo 4

Dungeons in Diablo 4 are separated into multiple types of activity. Depending on the World Tier played, you can unlock multiple types of instances that influence your playthrough, such as:

• Campaign Dungeons
• Quest Dungeons
• Capstone Dungeons
• Nightmare Dungeons

After you finish your Main Campaign, you can explore new types of activity named Capstone Dungeons & Nightmare Dungeons. You can find Nightmare Sigils & access these dungeons only after you complete the Cathedral of Light & Fallen Temple Capstone Dungeons.

Diablo 4 Capstone Dungeons

To gain access to World Tier 3 difficulty in Diablo 4, you must visit the Cathedral of Light Dungeon & defeat the High Council & Curator. For World Tier 4, you must complete the Fallen Temple Capstone Dungeon on World Tier 3.The higher the World Tier is, the more bonuses it provides, such as:

• World Tier 1 – Enemies are Easy to defeat
• World Tier 2 – Enemies are more challenging, but they provide 20% increased experience and 15% more gold
• World Tier 3 – Enemies are way stronger, but they provide 100% more experience & loot. Sacred, Unique Items and Nightmare Sigils can now drop & Helltide events appear across Sanctuary
• World Tier 4 – Monsters overcome 40% of your resistance; they are fearsome, but you gain 200% increased experience & 15% more gold. Ancestral and new Unique items can drop

Nightmare Dungeons Requirements

Nightmare Dungeons represent one of the main end-game activities in Diablo 4. A nightmare dungeon scales from tier 1 all the way up to tier 100, increasing in difficulty and rewards as you reach a higher tier.

Any endgame activity requires a strong build and knowledge of the content. In Nightmare Dungeons, you must keep in mind that you have limited revives, and there are certain affixes (good and bad) that make it more challenging:

• Tier 1-10: 12 Revives & 3 Affixes (A positive one + Two Negatives)
• Tier 11-20:12 Revives & 4 Affixes (A positive one + Three Negatives)
• Tier 21+:12 Revives & 5 Affixes (A positive one + Four Negatives)

What is the recommended level for Nightmare Dungeons?

There’s no requirement or a perfect level when going for a specific Tier of a Dungeon. Still, we recommend going for a Nightmare Dungeon, which is maximum +3 levels higher than your current level, for the 25% increased experience.

Nightmare Dungeons Difficulty Scaling

In Nightmare Dungeons, monsters scale up by 1 level per Tier, starting from level 55 at Tier 1. Significantly higher-level monsters have more life, damage, and additional penalties against your damage.

Are Nightmare Dungeons Hard to Beat?

Completing a Tier 3 Nightmare Dungeon allows you to enhance your Paragon Board with upgraded Glyphs and increased stats. However, completing a higher Tier Dungeon without upgrading your gear, your legendary aspects, gems, or paragon could be the hardest achievement in the game.

Can you play Solo Nightmare Dungeons?

Any Nightmare Dungeon can be beaten solo if your build is strong enough to handle the fast-paced situations within the activity. A High-DPS class could handle everything with ease, while a more tanky version of a character would struggle to clear the adds, but excel in dealing with the damage taken. 

However, if you’re finding it challenging to solo Nightmare Dungeons at the level you desire, there’s no need to fret. Consider opting for a Nightmare Dungeon carry service. This service can assist you in surmounting difficulties and guide you toward achieving your gaming goals.

Nightmare Dungeon Rewards

There are many reasons to run a Nightmare Dungeon and constantly farm this type of activity: glyphs, XP, loot, more nightmare sigils & increased chances to get legendary and unique items.

Glyphs

Glyphs are powerful items that can be socketed into your Paragon Boards to enhance your build & character. These can be leveled up when you finish a Nightmare Dungeon to increase their potency and radius to cover a bigger area, making them one of the main reasons to run Nightmare Dungeons.

XP

As we recommended before, running a Nightmare Dungeon which is +3 levels higher than your current level, would be best to receive the +25% bonus experience while slaying the monsters.

Loot

Loot is another reason why you should run a Nightmare Dungeon. When you complete the activity, you will receive higher-rarity loot and chances for Legendary or Uniques.

What are Nightmare Dungeon Sigils?

A sigil is the key to transforming specific dungeons into Nightmare Dungeons.

How to get Dungeon Sigils in Diablo 4?

There are three ways to acquire Sigils currently in the game:

• Completing Whispers of the Dead
• Finding them during your Nightmare Dungeon Runs by slaying enemies/completing events
• Crafting them at the Occultist for Gold and Sigil Powder (acquired from salvaging unwanted Sigils)

Types of Nightmare Dungeon Sigils

There are two types of Dungeon Sigils currently in the game: The Sacred and the Ancestral sigils.

A Sacred Sigil is a World Tier 3 Nightmare Dungeon with a maximum of Tier 20 sigil, while Ancestral takes place in World Tier 4 with a minimum Tier 21 and a maximum Tier 100 Dungeon.

How to craft Nightmare Dungeon Sigils

Whether you find a Nightmare Sigil that you hate running, or a lower-tier one, you can salvage these items for Sigil Powder, which can be later used to craft specific tiers of Sacred or Ancestral Sigils. By visiting the Occultist in any location in the Sanctuary, you can salvage the desired Sigils to receive a small amount of Sigil Powder.

Nightmare Sigils Crafting Cost

• Tier 1-5 – Sigil Powder x3 + 4,000 Gold
• Tier 6-10 – Sigil Powder x6 + 6,000 Gold
• Tier 11-15 – Sigil Powder x11 + 8,000 Gold

How to reset Nightmare Dungeons

The first step to endlessly farm a Nightmare Dungeon is to find a Nightmare Sigil with the desired afflictions or layout. Use the Nightmare Sigil and enter the activity. Complete the first objective, open your map, and press the “leave dungeon” button.

This will teleport you out of the dungeon at the dungeon’s entrance. Wait for a couple of minutes, and the Nightmare Dungeon will reset. Go back in, and you will see that the enemies have respawned. Clear the dungeon again, then leave. Repeat as many times as you wish.

Note: Please keep in mind that the Nightmare Dungeon reset strategy only works when playing solo.

It’s not for the faint of heart, but if you’re up for a real challenge, then the Nightmare Dungeons are definitely worth checking out. Be prepared!
