There should be a low tier craftable or purchasable cape that prevents the wet status from rain (rain only).
It can either be crafted using resin and some other random material, or sold by either Haldor or Hildir.
It will be helpful during the early stages of the game when your efficiency gets wrecked by the constant wet debuff.
I wish they added floods.
During months of endless rain, there should be a chance for the lakes and waterways to rise up and damage/demolish any nearby buildings.
And for cliffs and high elevation, there should be chances of landslides.
My 1st region had a rich fishing pond, i thought that this would be the main food source for my region, but on year 3, a massive drought struck the region a month before harvest season, it also dried up the pond.
Several years have passed but the pond is still struggling to reach full capacity, i have to leave it for several months just for it to go past 112
