Nether Bricks

Nether Bricks are a block used to form Nether fortresses in the Nether.

Obtaining
Nether bricks can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing.

Natural generation
Nether brick forms the walls and supporting pillars of Nether fortresses.

Usage
Nether brick is non-flammable and immune to Ghast fireballs, making it a suitable shelter material for the Nether. When walking on it, it makes the same step sound as stone.
