How to Reach Kruu'Sul Crags & Drang'Gal Fortress - Grim Dawn

In Grim Dawn: Fangs of Asterkarn, players need 10 Tainted Meat and an Inert Sphere bought from Dulgirr to start the route to Kruu’Sul Crags.

Combine them at the Purifying Altar to create a Magma Sphere, then use it on the Glacial Wall in Ulo’s Springs to open the path.

That unlocks the optional Kruu’Sul Crags area and ties into the Glacial Warming achievement.

Drang’Gal Fortress is still unavailable for now, as it’s reserved for a future Challenge Dungeon.
