The Flayer Jungle is a jungle zone in Act 3. The zone can be accessed from both the Spider Forest and the Great Marsh, and connects to Lower Kurast, whose entrance is guarded by a pack of Deathfire Bearers led by the super unique The Vizier.
Somewhere in the Flayer Jungle lies the entrance into the Flayer Dungeon. Players need to explore the maze-like dungeon in order to obtain Khalim's Brain. The optional dungeon Swampy Pit, which leads to the uberlevels Proving Grounds and Genesis, is located here. The waypoint of the Flayer Jungle is always located near the Swampy Pit.
