Bul-Kathos' Nightmare

Colossal Ancient Statues are used exclusively to open the Red Portal to the Uber Ancients encounter.

When the portal is opened, players can challenge the Uber Ancients, a pinnacle endgame fight that directly drops an upgraded Facet upon defeat. No additional crafting or combination steps are required.

These statues exist for one purpose only: granting access to the Uber Ancients and the Facet reward they drop.
