Nightmare Sigils in Diablo 4 are vital for Wanderers who want to discover all the secrets Sanctuary dungeons have in the endgame. Here’s how to unlock Sigil Crafting to craft Nightmare Sigils in Diablo 4.

Diablo 4 players can focus on farming unique items and legendary affixes after the endgame, and they’ll need to look for them in the 150 dungeons scattered around Sanctuary’s map. Players who want to increase the drop rate of these materials will need items called Nightmare Sigils, which transform each space into a new demonic challenge.

However, sigil crafting isn’t as straightforward as it seems, as Wanderers will require Sigil powder, a material that can be tricky to obtain. Here’s what you need to know about Sigil powder and how to craft Sigils in Diablo 4.

What is a Nightmare Sigil in Diablo 4?

Nightmare Sigils are consumable items in Diablo 4 used to upgrade standard dungeons into Nightmare Dungeons, which are important in the endgame. Nightmare Dungeons are filled with stronger enemies, and they also are a key element to level up faster.

Each Sigil corresponds to a dungeon located somewhere in Sanctuary and has different crafting costs depending on the Tier you’re playing in.

How to get Sigil powder in Diablo 4

Sigil Powder in Diablo 4 can only be obtained by completing Nightmare Dungeons or salvaging unwanted Nightmare Sigils at the Occultist’s shop. Since the process of getting enough Sigil Powder to unlock high-level Nightmare Dungeons is quite lengthy, we would recommend focusing on the best dungeons first to get better materials for crafting.

How to craft Nightmare Sigils in Diablo 4

To unlock Sigil crafting in Diablo 4, you’ll need to reach World Tier 3 and complete at least one Nightmare Dungeon. You’ll be able to access your first Nightmare Dungeon by acquiring Nightmare Sigils from enemies or completing Whispering Tree’s bounties.

When you’ve done so, a priority quest will appear with the Occultist in Kyovashad. He’s the one who’ll grant you the ability to craft Sigils, as well as being able to salvage them for Sigil Powder.
