New Season, New Nightmare Dungeon Rotations. This time, some old favourites are back, and they remain favourites for a reason. Efficiency is the name of the game, and after Blizzard’s last pass, it only got better. So here are the top 10 Nightmare Dungeons for you to farm your heart out, and hopefully your enemies’ too!

What are Nightmare Dungeons? Why are they integral?
Nightmare Dungeons serve as a distinctive element in Diablo 4, a renowned action role-playing game. These dungeons undergo modifications, presenting heightened difficulty and increased rewards compared to regular ones, and obtaining access requires a Nightmare Sigil. Their significance lies in facilitating expedited character and glyph advancement, consistently yielding glyphs and high-rarity loot, and guaranteeing four item rewards upon successful completion. Engaging in the most lucrative Nightmare Dungeons becomes crucial for acquiring superior loot, additional XP, and faster progress in glyph levelling. Furthermore, these dungeons feature randomly assigned positive and negative affixes, introducing specific benefits and multiple debuffs to enhance the challenge. The tier of a Nightmare Sigil dictates the dungeon's monster level and the number of negative affixes. Additionally, players have the option to create their own sigils through salvage and crafting at an occultist vendor. It's noteworthy that Nightmare Dungeons in Diablo 4 draw inspiration from Mythic+ Dungeons in World of Warcraft or Greater Rifts in Diablo 3.

10. Yashari Sanctum

One of the main components of what makes a good Nightmare Dungeon is Mob Type, and what you’ll face inside it. Yashari Sanctum ranks so ‘low’ (among over 30 total nightmare dungeons) as 10 because while it has a good layout (another core component), the mob type it has isn’t the best and can be rather annoying depending on the build you’re playing.

Why Yashari Sanctum is Great:

• Good layout.
• High Mob count for EXP farming.
• Fair Speed clearing for Glyph Farming.

How to get to Yashari Sanctum:

• You can access it through Caldeum, in Kehjistan, or by teleporting directly to it.

9. Dead Man’s Dredge

One theme you’ll notice is that the best NM dungeons in the game consist of 3 major factors. Layout, Mob Density, and Objective Requirements. And Dead Man’s Dredge is great for the insane density it has.

Why Dead Man’s Dredge is Great:

• Great layout.
• Extremely high Mob count for EXP farming.
• Fair Speed clearing for Glyph Farming.

How to get to Dead Man’s Dredge:

• You can access it through Gale Valley, in Fractured Peaks, or by teleporting directly to it.

8. Mercy’s Reach

Mercy’s Reach is probably one of the most well-known dungeons because of just how easy it is to level up in it if you’ve completed the campaign. It’s such a good layout with a high density of Elite Mobs in the first section that every guide uses it as a parameter, and now it’s back on the menu!
