how to unlock glacial fissure diablo 4

Quick Scoop: To unlock Glacial Fissure in Diablo 4, you need to be in World Tier 4, collect 9 Distilled Fear and 250 Sigil Powder, then craft the Glacial Fissure Nightmare Sigil at an Occultist and use it. The dungeon is in the Desolate Highlands area of Fractured Peaks, near Kyovashad, and it opens access to the Beast in the Ice boss fight.

How It Works

1. Reach World Tier 4 first, since that is the requirement for the Glacial Fissure Nightmare Dungeon.

2. Gather 9 Distilled Fear , which drops from Tier 30+ Nightmare Dungeons.

3. Collect 250 Sigil Powder , usually by salvaging Nightmare Sigils at the Occultist.

4. Visit an Occultist and craft the Glacial Fissure Nightmare Sigil.

5. Use the sigil, then enter the dungeon and fight The Beast in the Ice.

Location Notes

The Glacial Fissure is in the Desolate Highlands in Fractured Peaks, and some guides place it just north or northwest of Kyovashad. Once the sigil is crafted, the dungeon appears on your map and can be entered like other Nightmare Dungeons.

Extra Tip

If you are farming Distilled Fear, expect a bit of RNG; it is not guaranteed every run, so you may need several Tier 30+ Nightmare Dungeon clears. In later-season or Torment boss versions, some guides also mention higher material costs, including Stygian Stones for the Torment summon.

TL;DR

Unlock it by getting to World Tier 4, farming 9 Distilled Fear and 250 Sigil Powder, then crafting and using the Glacial Fissure Nightmare Sigil at an Occultist.
