Hub Crypts

The Graveyard Caves or Graveyard Crypt is an unnamed section of the Coal Mine that holds tough zombie variants for using in training Zombie Slayer.

Mobs
In the caves you can find Crypt Ghouls, its a great way to get exp for the Revenant Horror slayer quest.

You can also find Golden Ghouls in the mines.

Location
As the name suggests you can find the caves in the graveyard and there are two entrances:
 * - This entrance is better as it does not require Superboom TNT.
 * - this is in the Coal Mine entrance, and instead of going straight you go left. You will need Superboom TNT to enter.

Resources
In the mines are Coal and Cobblestone, but mining those will be inefficient since you will be attacked by Crypt Ghouls.
