World Tier 4 end-game content in Diablo 4 is all about farming summoning items so that you can fight bosses like the Beast in Ice. Before you can take on the Glacial Nightmare, though, you need the right location for the Lair and some Distilled Fear to go along.
Where to Find the Beast in Ice in Diablo 4
You can find the Beast in Ice within the Glacial Fissure lair in the Desolate Highlands of the Fractured Peaks. Like all the other end-game bosses added in Season 2, the Glacial Fissure is marked with a horned skull on a dungeon gate. If you haven’t taken down the boss in the fissure yet, then there will also be an orange dot.
The Beast itself won’t be as quick to find in the lair as other end-game bosses. You’ll need to clear out the first part of the dungeon before you reach a locked gate that requires a special sigil to breach. If you have the right materials, then you won’t have to worry about the gate at all.
How to Summon the Beast in Ice in Diablo 4
You need to collect nine Distilled Fear and then craft a Glacial Fissuire Nightmare Sigil to summon the Beast in Ice. To start collecting Distilled Fear, you must complete Nightmare Dungeons at Tier 30 or above. Typically, you can get at least one bottle of fear per run, but they won’t always drop as a reward or from enemies.
When you have nine Distilled Fear, bring it to an Occultist Vendor and open up the Sigil Crafting Tab. One of the first options in the Ancestral drop-down is the Glacial Fissure Nightmare Sigil. Craft the item and consume it to gain access to the Beast in Ice at the Glacial Fissure Lair. Be ready for a level 85+ fight before you head in.
After you slay the beast, find out where Duriel is located in Diablo 4.
