Crystal Floor

Place on the ground to create paths or to spruce up your floors.
Overview
The Crystal Floor is a crafted flooring item used to create decorative paths and other paved areas. Like all flooring, it provides a small +0.1 Player Speed boost, but only when placed outdoors on The Farm. Flooring also helps keep heavily used areas clear by preventing Grass or Trees from growing there, which can reduce clutter and make movement easier.

Crystal Floor is not completely permanent, however. It can be displaced by lightning or destroyed by weeds, so it is best used in areas that are maintained regularly or protected from environmental damage. Because of this, players often place it in planned layouts where aesthetics matter and where it is easy to replace tiles if needed.
When placed, Crystal Floor has a distinct seasonal appearance, with one look used in spring, summer, and fall, and another in winter. This lets it remain visually consistent with a farm design while still fitting the changing seasons.
