A place located deep below the Formorgar Mines. It is said that the Ice Witch mistress is asleep in this crypt and that nobody is able to wake her from her slumber.
The Yakchal Crypt is in the final room of The Ice Islands Quest. Near the north-east stone, there is a large room sealed by doors and inhabited by around 20 Ice Witches. To wake Yakchal up, use a Frozen Starlight on her sarcophagus. There is a 10% chance that the starlight breaks in the process.
The "X" marks the obelisk for the quest, the green arrows mark places where you could levitate up, in order to get to a save spot where you could rest. The pink arrow marks the Crypt.
