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, Heat will accumulate over time, causing the player to take burn damage at set intervals. Mitigation of Heat requires Heat Armor or its stronger counterparts, such as Flamebreaker Armor or the Armor of Yog.
