Dripstone Block

The dripstone block is a rock block that allows pointed dripstone to grow beneath it.

Breaking
Dripstone blocks require a pickaxe to be mined, in which case it drops itself. When mined without a pickaxe, it drops nothing. It can be blown up by TNT, in which case it also drops itself.

Natural generation
Dripstone blocks can be found in dripstone caves. Clusters of dripstone blocks can also rarely generate in other cave types (details needed).
