The Sewers can be entered from either the Kurast Bazaar or Upper Kurast. The sewers consist of two levels. Unlike other dungeons, the second level can only be entered after a special Sewer Lever has been pulled. The lever is guarded by the Super Unique Sinner Goldblight of the Flame.
The second level consists of a small chamber with a pool in its centre. Khalim's Heart can be found within the golden chest in this area.
