Cobblestone is a Craftable Turf which allow players to lay down their own Roads. Similar to natural roads, they will speed up the player by 25%. However, unlike natural roads, Cobblestones can be moved using the Pitchfork. Small patches of it can be found in Mosaic biomes.
Laying Cobblestones down inside your base and along paths you take often can significantly decrease your character's travel time.

Cobblestones can be crafted with 1 Rocky Turf and 1 Boards and requires an Alchemy Engine to prototype
