Eliminate monsters and grab the Key Stone Key Stone and drag it onto Ancient Seal. Each wave approximately drops one Key Stone. Allowed time on this floor is 20 minutes.

In order to get to this floor, a player level 75+ must talk to the Blacksmith on floor 6. Only then will all players on that floor move to this floor. Your aim on this floor is to destroy all Metin of Death. Once destroyed, monsters will appear along with Metin of Murder. Once destroyed, it drops an Unknown Old Chest. Open the chest and it either contains nothing or a Zin-Ga-Gui Tower Map. Click on this item to proceed to the next floor.
Eliminate the monsters and get hold of the Zin-Bong-In Key. They also drop a lot of fake Bong-In Key. Drag the Zin-Bong-In Key onto the Sa-Soe Statue and you will proceed to the last floor.
On the final floor your objective is to eliminate the Death Reaper. Watch out for all the other monsters appearing here.
Once you've killed the boss, you will be teleported to the entrance shortly after.
