Escalating Nightmares are one of the bigger additions to Diablo 4’s Season 9, but since the system is still new, a lot of players are unsure how it works or when it unlocks. If you have picked up one of the new Escalation Sigils and are wondering what exactly you are getting into, here is a quick breakdown.
These dungeons are essentially a chain of three back-to-back Nightmare Dungeons, with each one stacking on the affixes from the previous run. Things can get rough quickly, especially once you reach Torment difficulty and unlock the final phase.
How to Start an Escalation
- Escalation Sigils can drop from Horadric Caches, Strongrooms, or the Seasonal Reputation track.
- Once you activate a Sigil, it will teleport you into the first dungeon.
- After clearing it, a portal opens to the next one, showing you the added affixes.
- After three, if you are in Torment difficulty, you head straight into Astaroth’s Lair for a boss fight.

What to Expect from Astaroth
Astaroth has his own mechanics and hits harder than usual since he inherits your affixes. If you want help with that fight, we have a full boss guide on our site.
Loot, Bonuses, and Affixes
Escalating Nightmares can also come with special affixes that spawn:
- XP orbs (good for leveling)
- Extra shrines
- Treasure Goblins
- Loot chests full of materials
You will also earn Ancestral Legendaries, Uniques, gold, and other late-game drops.
This system is available on both Seasonal and Eternal characters, and it becomes one of the better ways to gear up fast once you hit the late game.
