Obsidian caves
The Obsidian caves, also known as the TzHaar caves, can be found inside the volcano on Karamja. When players enter the Karamja volcano they will see a strange red-black entrance, which leads to the TzHaar caves.
The caves are inhabited by strange monsters, also known as Tzhaar monsters.
The obsidian caves feature many things to do, including the Fight pits and the Jad minigame. There is also a TzHaar banker and a healer there, and the Tokkul exchange, where players can exchange their Tokkul from the TzHaar monsters and Jad for several items.
