Lava maze
From Emps-World Wiki
The Lava maze can be found deep in the Wilderness, at around level 50. It is easiest accessable by using the Obelisk to transport to it. The entrance to the Lava maze is situated on the western side. However, players can also enter the maze via the stepping stone shortcuts on the southern and the northern side of the maze, using the Agility skill.
Players can find an entrance to the Lava Maze Underground west of the Lava maze and in the center of Lava maze. The maze is also home to various lower level monsters and holds a Lava Eel fishing spot.
