Diablo 4 Season 9: Escalating Nightmares Bring a Ruthless New Endgame Challenge

Diablo 4’s Season 9 introduces one of Diablo IV Goldthe most intense endgame systems Blizzard has ever implemented. Dubbed Escalating Nightmares, this new dungeon gauntlet arrives as part of the “Sins of the Horadrim” update, currently live on the Public Test Realm (PTR). It’s a punishing evolution of the traditional Nightmare Dungeon experience — and it’s designed to test the limits of even the most seasoned adventurers.

If you’ve been tearing through Nightmare Dungeons without breaking a sweat, Escalating Nightmares are here to humble you. This system doesn’t just crank up the difficulty — it adds a layer of long-term strategy, brutal attrition, and deadly boss mechanics that demand flawless execution. Let’s break down how it works and why it’s poised to become the new crown jewel of Diablo 4’s endgame.

What Are Escalating Nightmares?

At their foundation, Escalating Nightmares are a chained sequence of three Nightmare Dungeons that increase in difficulty with each completed stage. What sets them apart from ordinary dungeons is the cumulative affix system: modifiers don’t reset — they stack. That means the chaos you encounter in dungeon one is only the beginning.

By dungeon two, new affixes are layered onto the original set. By dungeon three, you’ll be contending with an avalanche of synergizing hazards. This design makes every decision — from build choice to movement and ability usage — critical to survival.

Your reward for enduring this gauntlet? A revamped and vicious final boss fight featuring Exalted Astaroth and his monstrous steed, the Amalgam — both deadlier than ever.

How to Access Escalating Nightmares

You won’t stumble into these trials by accident. Escalating Nightmares require a special consumable called an Escalation Sigil, which cannot be crafted and must be earned. Here's how to unlock them:

    Escalation Sigils drop from Horadric Caches, which are awarded after completing Strongrooms on Torment I difficulty or higher.

    Using the sigil will open the first dungeon in the Escalating Nightmare sequence.

    Upon completing each dungeon, a Horadric Portal opens, transporting you directly into the next tier — and revealing the new affixes now in play.

There are no checkpoints or do-overs — once you start, all three dungeons must be cleared in buy Diablo IV Gold a single, continuous run. Fail midway, and you lose the opportunity, the sigil, and any uncollected rewards.
