I've sketched out a couple of ideas.
1) A device that does NOT allow mushrooms to grow in its radius (the radius is configured to cover the entire base)
1.1) An alternative mode of this device, which increases the growth of mushrooms in the range. (it may even change the effects of mushrooms and add new species) The device is unique and is not sold in the store.
2) Convenient trolley for transporting large objects. the reference picture is attached.
3) Folding chair (second picture) it is convenient to carry, it weighs little. You can motivate players to use the sitting function if the sleep (stamina) parameter is spent half as much while sitting.
