Compressed Cobblestone (Extra Utilities)

Compressed Cobblestone is a collection of storage block for cobblestone. The block shows the amount of Cobblestone stored in the block in it's tooltip. Compressed Cobblestone is 9 Cobblestone stored in a single block and Octuple Compressed Cobblestone stores 43,046,721 Cobblestone in a one block space (the amount of cobble stored in each block is exponential). The higher the level of compression applied to the cobblestone, the darker the block becomes, and the higher the blast resistance of the block - Septuple and Octuple Compressed Cobblestone are resistant to the Wither. Triple and Quadruple Compressed Cobblestone is used in the creation of the Portal to The 'Deep Dark'.
