Khazad-dûm

Khazad-dûm is a location in the Crystal Hollows, more specifically the Magma Fields, where the Topaz Crystal can be obtained. Claiming the crystal requires the defeat of Bal, a magma cube boss which spawns periodically in the center. After the boss sinks into the ground, the crystal will spawn close-by and become claimable.

Like the rest of the Magma Fields, will rise over time, causing the player to take burn damage at set intervals.
