How to Find Nightmare Sigils in Diablo 4

Learn how to find Nightmare Sigils in diablo iv. They drop from World Bosses, Nightmare Dungeons, and Tree of Whispers caches in World Tier 3.

Nightmare Sigils are consumables that turn one specific Dungeon into a Nightmare Dungeon. Nightmare Dungeons are cleared like normal Dungeons - you go inside and complete the dungeon’s objectives, which vary by Dungeon but always involves killing hosts of enemies and usually culminates in a fight with a Dungeon Boss. While your objectives in Nightmare Dungeons are largely the same as in normal Dungeons, there are some complications thanks to Dungeon Affixes.

Not all Nightmare Sigils are created equal, varying both by what Dungeon they affect, what Tier they are, how many revives are allowed, and by what Dungeon Affixes will be in play. A Nightmare Sigil’s Tier ranges from Tier 1-20 (in World Tier 3) and from Tier 21-100 (in World Tier 4), and influences both how difficult and lucrative the Nightmare Dungeon will be. A Nightmare Sigil’s Tier will generally scale to the Tier of the Nightmare Dungeon you’re in, and are World Tier gated. In other words, don’t expect a Tier 20+ Nightmare Sigil to drop in a Tier 6 Nightmare Dungeon on World Tier 3, but sometimes you’ll find ones of slightly higher (or considerably lower) tier than the current tier of the Nightmare Dungeon you’re in.

Revives are pretty simple - this is how many times players in your party can die before failing the Nightmare Dungeon. While it’s generally not that hard to build up Nightmare Sigils, they are a resource, and failing Nightmare Dungeons does somewhat squander them, so try to be a little more cautious in Nightmare Dungeons.

Dungeon Affixes, however, are a bit more obtuse. These are bound to the Nightmare Sigil, and will be bestowed upon any Nightmare Dungeon created with that Nightmare Sigil. These random modifiers vary both in number (ranging from 3-5, depending on the Tier of the Nightmare Sigil) and in type. You’ll usually have at least one positive modifier, but most of them will be detrimental. Creating portals that spawn enemies, enraging nearby monsters when their fellows are slain, adding some form of elemental damage to all enemy attacks, granting all Elites a specific affix (“Suppressor”, “Thunder Lance”, etc.) and conjuring a “Drifting Shade” that chases players throughout the dungeon, dealing AoE damage if it catches you are all Dungeon Affixes we’ve encountered.
