How to Get Nightmare Sigils in Diablo 4

Nightmare Dungeons might be one of my favorite endgame activities. There's plenty of challenging enemies, unique modifiers, but more importantly – loot! Here's how to get Nightmare Sigils in Diablo 4.

Getting your first Nightmare Sigil is the hardest part. But once you have one, you’ll practically be swimming in them. I’ll delve into a more thorough description of how to get these Sigils below, but here are the two ways to get them:

To unlock Nightmare Sigils, you’ll need to beat the campaign. Once that's done, you’ll get a series of post-campaign quests, including a prompt to complete the Capstone Dungeon in Kyovashad. Doing this will allow you to unlock World Tier 3, which you’ll need to be on to unlock Nightmare Dungeons. Once you’ve unlocked World Tier 3, switch your difficulty over.

Once you’ve beaten the Capstone Dungeon, head over to The Whispering Tree, which you met during Act 4 of the campaign. This tree will put you in its employ, tasking you with gathering Grim Favors. Gather 10 for the Tree and you’ll get a choice of three reward caches. No matter what cache you pick, there is a chance of getting a Nightmare Sigil. This step is necessary, as it's how you’ll get your first Nightmare Sigil.

When you’re in a Nightmare Dungeon, there's a chance that Nightmare Sigils will drop from random enemies. Stronger enemies will have a chance to drop more Sigils. These Sigils can also drop at the end of the dungeon.

Once you have a Nightmare Sigil, go into your inventory and tab over to the right menu called "Consumables". In this menu, you’ll see your Nightmare Sigil, which you can click to use. Doing so will change the icon of the selected dungeon on the map, making it easier to find.

All Nightmare Sigils will apply a buff or debuff on the associated dungeon. But completing them will allow you to upgrade your Glyphs on your Paragon Board.
