Cracked Stone

Cracked Stone is one of the Bombable blocks. It will be destroyed by the custom explosion used by Thrown Bombs.

It's primary use is to create barriers you can use to make your games more linear. You can use these blocks to partition off any areas you don't want the player to be able to reach until a certain point in your game, then give them Thrown Bombs when you want them to be able to traverse to those areas. This would also be useful for hidden or secret areas. It also means you don't always have to rely on redstone circuits to move from area to area.
