How to unlock the Nothing underneath achievement in Graveyard Keeper - Definitive Guide
Then you will need to
Then you will use this item as the key to unlock the gate
Returning to the 15th, finding what path or single room you missed, and clearing it out before once again taking the door should pop the Achievement. All prior baddies should still be dead like any other floor you escaped from so don’t worry about the annoyance of re-clearing the whole floor.
Level 15 is the last level of the dungeon. You can find the dungeon in the area behind the gate where Snake stands. Once you enter the dungeon, you’ll have to kill all the enemies on the level in order to proceed down the stairs once you find them. You won't be able to progress any further than the 10th floor until you get far enough along Snake's tasks where you obtain a medallion to unlock the rest of the floors.
The only way to exit the dungeon is to either die or go back to the steps. The teleportation stone will not work inside the dungeon. The enemies don’t respawn, so if you can’t finish the level, don’t worry. You can go back later and clean up the rest and proceed to the next level.
