There is just nothing to do then :P chopping trees, mining stones etc = just grinding, so i was hoping i will get something new in tier 3 :)
p.s. is there something can be done with vehicle? i crafted it but didn't find where to use.
btw farming relics very boring process at this point, maybe you will consider to change it to something else (in sense of how it works) as after 2-3 times getting there it actually became annoying.
Fishing in other hand realized much better then in Stardew Valley - much more intuitive :)
