Dungeon Bricks

Dungeon Bricks are a non-craftable type of brick from which the Dungeon is constructed. On world generation, one of three colors of Dungeon Brick is chosen to create the entirety of the Dungeon. Dungeon Brick is one of very few block types that is impervious to explosions. A Molten Pickaxe or better is required to mine it, unless within the 30% of world width centered at world spawn point.
