Diablo 4's second season introduced exciting bosses, and one of them, the Beast in the Ice, lives in the Glacial Fissure Nightmare Dungeon. You can't just wander in if you're in the area, though. Here's how to find and unlock Diablo 4's Glacial Fissure Dungeon.

The Glacial Fissure Nightmare Dungeon in Diablo 4 is located in Desolate Highlands, near the Eastern Pass. A Glacial Fissure Nightmare Sigil is enough to get you into this dungeon, and the Sigil can be crafted at the Occultist.

Glacial Fissure is home to The Beast in the Ice. All Uber bosses have unique drops, and The Beast is no exception. But here's what you'll need to do to craft the Glacial Fissure Nightmare Sigil and get into the Glacial Fissure.

Once you activate the Sigil, you can teleport to the entrance of Glacial Fissure by clicking on the icon on the map. Inside, you'll find yourself in a normal dungeon, but the Beast in the Ice awaits you at the end.
