Limestone

Limestone is a block found in the Atum dimension. It is the equivalent to Overworld stone. It looks very similar to sandstone.

When you mine Limestone you will get Limestone Cobblestone.

It can be used in the crafting of Limestone Swords and Limestone Tools. It can also be used to craft Limestone Furnaces, Bricks, Walls, & Stairs.

Limestone can be interchangeably used to make Atum Portals instead of sandstone.
