Description

This tool can crush stone, bones, and other things, into fine dust.

The grindstone can be used to grind stone, sandstone, and granite. Both ground stone and sandstone are required to build power level 2 house parts. It processes very slowly, so it is recommended to keep it filled while doing other tasks, or to fill it just before sleeping, to process a whole stack of stone instantly. It must not have a roof above it to function.

Note that players must receive granite in their inventory to unlock the grindstone.
