The Catacombs - Floor X

The Catacombs - Floor X was the final floor in The Catacombs Dungeon with Necron. This boss is described in game as follows "Right hand of the Wither King. Inherited the Catacombs eons ago. never defeated, feared by anything living AND dead." but appears on Floor VII rather than Floor X.

As of SkyBlock Update 0.9.13, this has been removed.
