How to Enter Nightmare Vaults

Use Nightmare Vault Sigils

Nightmare Vault sigils are needed to access Nightmare Vaults. Players need to activate the sigil in order to activate the Nightmare Vault and claim its rewards after a successful run.

How to Get Nightmare Vault Sigils

Crafted From Occultists

Nightmare Vault Sigils can be crafted by the Occultist similar to Nightmare Dungeons. Crafting a Nightmare Vault Sigil will cost Sigil Powders and Shattered Stones.

Monster Drops and Vault Rewards

Nightmare Vault Sigils can also drop from monsters inside the Nightmare Vaults. Completing a Nightmare Vault also guarantees a Nightmare Vault sigil as a reward.

Nightmare Vault Rewards

Extra Wardwoven Chest

Glyph XP

Diablo 4 - Vault Gluph Reward
Nightmare Vaults also reward players with Glyph XP, making it a good alternative for regular Nightmare Dungeons.

Nightmare Vault Sigils

Completing a Nightmare Vault guarantees a Nightmare Vault Sigil which is quite handy if players have run out of materials for crafting another sigil.

Difference From Normal Vaults

Nightmare Dungeon Affixes

Nightmare Vaults have a set of affixes similar to Nightmare Dungeons, making the vault more challenging.

Best Nightmare Dungeon Affixes

Limited Revives

Nightmare Vaults have limited revives. When you die beyond the limit, you will be kicked out of the Vault and the sigil will be consumed.
