Chiseled Ominous Stone

These blocks seems to resonate well with the Illagers. Perhaps they can be seen as the stone to their beloved Dark Oak.

By breaking Ominous Stone, you can obtain its cobbled counterpart. Much like regular cobblestone, you can smelt it to obtain Ominous Stone.

Using a Pickaxe on a Cobbled Ominous Stone will turn it into a path the same way dirt paths are made with shovels.
