Nightmare Dungeons are basically endgame kinds of side quests that are really hard to complete. The difficulty is determined by the various Diablo 4 Nightmare Dungeons Tier levels. These Tier Levels range from Tier 1 to 100 level. Going past Tier 20 of these Nightmare Dungeons is not suggested if you are at level 40 or below. You can literally finish the primary campaign of Diablo 4 under level 40, but the difficulty for these Nightmare Dungeons is set.

  • You must progress through different challenging tier levels of Nightmare Dungeons and face battles.
  • As you keep moving forward, you will receive upgraded loot and Gear.
  • The higher gear level you have, the more chance of survivability you have in each Nightmare Dungeon.

The tiers above level 20+ are exclusive to the World Tier 4 level in Diablo 4. You cannot access tiers above 20 if you are still at World Tier 3, as high as it is. The fastest way to get to Tier 20+ above is by adding friends who have already passed the tests of most Nightmare Dungeons and helping them. Once you acquire a decent loot, you can start completing all the tiers before 20, as it will be a piece of cake.

How To Unlock Nightmare Dungeons?

In order to unlock these Nightmare Dungeons, you will need to change various normal dungeons into Nightmare ones. You will unlock Nightmare Dungeons as an endgame activity but won’t be able to enter one initially. You need a special item known as Nightmare Sigils in order to unlock each Nightmare Dungeon. These items are consumable and used primarily to open or turn normal dungeons into Nightmare Dungeons. 

Nightmare Sigils

  • Nightmare Sigils have different attributes that are set on specific dungeons and only turn those dungeons into the Nightmare Dungeons.
  • Each Nightmare Sigil has a different Diablo 4 Nightmare Dungeons Tier Level.
  • These tier levels determine the tier levels of the set Nightmare Dungeons on the map.
  • The tier level of each Nightmare Sigil determines the varying difficulty as well as the number of enemies you face.
  • As you move up tiers, the number of tiers and the number of revives goes down, and affixes go up.
  • You will start from  “Tier 1” Nightmare Sigil, and the next tier can be found or rewarded after the completion of Tier 1.
  • Your gear is essential to survival in these Nightmare Dungeons since you cannot depend on the positive affixes.
  • Certain levels need to be reached in order to unlock further Nightmare Sigils with Tiers above 1.
  • The Higher the difficulty or tier of a dungeon, the better and more rewards you get after its completion.
  • Each Dungeon has a task to find certain objects or opponents and defeat the final boss as the final part.
  • Some Reddit users have sought to check every different Diablo 4 nightmare dungeon tier level and give out tips.
  • Nightmare Sigils can be hard to get, so you should probably start from tier 1 sigils and hope to find more at the end of each dungeon.

While talking about the Diablo 4 Nightmare Dungeons tier levels, you must know that certain hurdles and rules are set when you get a high or low-tier Nightmare Dungeon. They are basically these modifiers of the dungeon that sort of choose the difficulty level you will face. These set rules are known as “Affixes”. Affixes make sure that the higher tier you get, the more difficult and challenging it gets for you. 

  • Affixes modify and enhance the experience of a Nightmare Dungeon.
  • It may be fun and annoying at the same time,
  • There are two types of affixes one is negative affixes and the other is positive affixes.
  • Positive affixes alter the dungeon aspects to your advantage to give you that slight edge.
  • On the other hand, the negative affixes make sure that the aspects of the dungeon are rigid and difficult.
  • As you go higher in tiers, the positive affixes and negative affixes will decrease.
  • These substantial changes are set as the highest tier has five affixes while the lowest has three.
  • Positive affixes give you the advantage of increasing your frost, poison, or any other damage to a foe.
  • Negative affixes, on the other hand, do things like increase the elemental damage from monsters.
  • The negative affies can also change the environmental aspects of a dungeon against you.
  • The most deadly affix is the Stormbane’s Wrath, which causes lighting strikes against you while you move.
  • The best positive affixes are the ones that increase the dropped loot from the monsters.
  • The additional drops can ensure you get extra gold, Nightmare Sigils, or gems.
  • Revives are also affected by the affixes set by the Nightmare Sigils.
