↖ Understanding Nightmare Dungeons

Nightmare Dungeons are enhanced versions of normal dungeons, featuring amplified difficulty and affixes. These dungeons become accessible only in the endgame after completing the campaign. Nightmare Dungeons are organized in tiers, with up to 100 tiers representing increasing difficulty. Each tier scales up monster damage, health, and levels.

↖ Different Types of Sigils

There are two types of sigils: ancestral and sacred. Ancestral sigils are tied to the world tier, while sacred sigils are available only at higher world tiers. The number of revives allowed also differs between the two types, with ancestral sigils having up to 12 free revives, and sacred sigils allowing only four. It's crucial to consider revives and affixes when strategizing and aiming for high-level dungeon clears.

↖ Positive and Negative Affixes

Nightmare Dungeons feature both positive and negative affixes. Positive affixes, represented by green text, offer benefits such as increased gold find. Each season introduces a new positive affix. Negative affixes, on the other hand, include environmental modifiers, monster damage buffs, defensive buffs, and utility buffs. Paying attention to these affixes and adapting your strategy accordingly is vital for success.

↖ Choosing the Right Tier

For efficient leveling and glyph progression, it's recommended to select a Nightmare Dungeon tier that is around 50 to 53 levels below your character's level. This ensures optimal experience gain and allows for faster glyph leveling. Aim to be three levels behind the monsters for a maximum 25% bonus XP. As you approach level 100, consider running tier 50 or higher dungeons to continue optimizing your progression.

↖ Crafting Nightmare Dungeons

Nightmare Dungeons can be crafted using the occultist's crafting interface. Visual powder, obtained from dungeon runs or salvaging sigils, is used for crafting new sigils. This flexibility allows you to skip unwanted dungeons or adjust difficulty according to your character's capabilities.

↖ Tips for Efficient Nightmare Dungeon Runs

Pay attention to environmental effects and avoid them whenever possible. They can pose significant challenges as you progress to higher tiers.

• Stack up the same sigils to chain runs together and avoid wasting time traveling between dungeons.
• Level up all your glyphs to at least level two in order of priority to easily locate and upgrade them.
• Focus on renowned grinding and other objectives before diving into extensive nightmare dungeon runs.
• Consider your character's level and the tier's difficulty to maintain an optimal balance between clear speed and experience gain.

↖ Conclusion

Nightmare Dungeons in Diablo 4 offer a challenging and rewarding endgame activity for experienced players. By understanding the mechanics, strategically choosing the right tier, and paying attention to affixes and environmental effects, you can progress efficiently and maximize your character's potential. Stay vigilant, master the dungeons, and prepare for the exciting journey of nightmare dungeon pushing.
