ferric stone

Ferric Stone is an environment block in Mindustry representing a piece of static map terrain; it is not a functional building, unit, item, recipe, or fluid and serves as part of the game's world geometry rather than a player-deployable structure. As an environment category entity, Ferric Stone is used by maps to define impassable or decorative tiles and influences placement of structures and pathing purely through its presence on the battlefield rather than through any interactive production or consumption mechanics.
