The Underhalls is a secret location within Minecraft Dungeons that can be unlocked within the Highblock Halls.


UNDER LOCK AND KEY – No keep is complete without a dungeon and Highblock Halls is no exception. Who knows what the Arch-Illager has hidden away down here? There's only one way to find out...

The Underhalls is located in the regal Highblock Keep. It's a dusty cellar full of forgotten things. Parts of the cellar look like jails, with chains hanging from the ceiling. Heroes need to fight their way through hordes of mobs, collecting loot while leaving. A Key Golem is needed to access the main area and escape.


The entrance can be found at the end of the starting hallway. The hero must go down to the point where there are two sets of stairs, and in the middle there should be two shields on the wall. Clicking the shield on the left opens a doorway. The hero must go through and collect the scroll.


The Underhalls is the cellar area of the Highblock Halls. It contains various chests and dark hallways, as well as various cells and other ruined structures left to be forgotten. Booby traps can be found here along with many ambush areas. It has a similar dark appearance to the Creepy Crypt, but the difference is that the halls were used possibly for torture or imprisonment of villagers before being forgotten about.
