Mercury Rock

Mercury Rock is a block added by 4-Space and generates in Mercury.

Obtaining
Mercury Rock generates naturally under the Mercury Surface Rock and Mercury Sub-Surface Rock layers in Mercury, and it always generates 4 blocks from the surface. From there on, Mercury Rock generates all the way down to Bedrock.

Mercury Rock can also be smelted using Mercury Cobblestone.

Mercury Rock requires at least wooden tools to mine, and a pickaxe is the fastest. Mercury Rock drops Mercury Cobblestone when broke.

Usage
Mercury Rock does not have any usage besides decoration, but can be used as a fairly defensive building material.
