Dungeon Bricks

Dungeon Bricks are a non-craftable type of Brick that the Dungeon is constructed out of.

Description
On world generation one of a variety of colors of brick is chosen to create the entirety of the dungeon out of. They are a coveted building material, as they're twice as strong as normal bricks and are completely impervious to explosions. A player can get them by mining, but they become relatively harder to mine in lower layers of the dungeon because of the monsters.

An uncraftable world generated item, there is a huge (but finite) number of bricks generated per world. Unlike other craftable bricks, it cannot be used to create a wall of the same color.

A Nightmare Pick is required to mine it.
