Nestled among the hills and fir trees of the Snowy Forest, the Yeti Lair appears as a square-shaped hill. Four entrances allow access to the ice-covered insides. Sheltered in the lair, you may find dozens or even hundreds of Yetis and one Alpha Yeti.
While using the progression system, the snowy forest will be under the effects of a perpetual blizzard. The lair and monsters inside will be magically protected while the blizzard is in effect. The blizzard lets up after the player defeats the Ur-ghast.
