Too Much Free Time
Yea, but that won't last for 8-20 hours.
I think you can continuously eat any food for the well fed effect, so if you make a load of feast tier stuff... I think a stack would do for about 10 hours
Unless theres a potion effect for it- then just autobrew into a dispenser.
--Edit--
I'm hearing "skip sand" because there's nothing in it that can't be gotten from the other two, other then the spores (and once you get 3...) and you can make the certus quartz dust into crystal with crafting.
Depends if you like limestone.
(may be needed for certain metals?)
