Mineral: Wetstone (a Cave-pril creation) (Patreon)

Water often seeps downward from the surface through tiny cracks and cavities into rocks deep underground, carving caves, forming underground lakes and streams, and creating fantastical formations with the minerals it takes along with it.

What if there were a type of stone far below the ground that didn't use water from the surface, but water that just appears within the stone?

This magical mineral was created for day 7 of Cave-pril.
