The Mazestone is a block added by Twilight Forest. This is one of the main materials in the Labyrinth structure. It can only be efficiently broken by the Mazebreaker, or by machines in other mods such as the RotaryCraftBoring Machine. Attempting to break it with a non-Mazebreaker pickaxe will take longer and lowers the durability of the pickaxe used by 16 points.
