i read the game creators post over not having preference between PVP over PVE but still the WORLD they have created have so many resources that let people kill for them, while in RL there are so easy to obtain
a) ROCK SALT, i sugest to be added to the mineral system


i personaly use it on the farm and is far better than the normal sea salt.
and olso increases milk and meat quality of the animals that consume it
should be easy to obtain even on surface plots and even more on underground mines.
it olso can be crafted making interesting pink/orange lanterns with some light source ;D for some curio studing ;D
2) Water purifictaion system

we already have in game the sand/glass/glass container and the boiling clauldron mechanics on the game so its easy to design a system that increases water Quality without having to use MAGIC
Fisrt basic system evaporation (addon to claudron)
QPuri System=(QGlass+QMason)/2 (the machine need to be damaged by use and repaired by using glass)
QWater=(QWater+QMetalCauldronQ+Puri System*3)/5
production is 200 lts per day (in game time)
Second advanced system coal+grave purify (building)

Coal Grain can be obtained by grinding Coal or Blackcoal at the Quern QCoalGrain=QCoal
Gravel Can be obtained ar the Quern QGravel=QRock
Coal Grain Can be obtained ar the Quern QCoalGrain=QCoal
Activated Coal Grain can be obtained at Ore Smelter QCoalGRain=((QCoalGRain*3)+QSmelter+QFuel)/5
QPury system=(Qclay+Qglass+QMetalBars+QMason)/4
QWater=(QWater+QPury Sytem+(QSand*2)+(QGravel*2)+(QActivated Coal Grain*5))/9
or if using normal coal grain
QWater=(QWater+QPury Sytem+(QSand*2)+(QGravel*2)+(QCoal Grain*2))9
Coal grain need to be used as a resourse as any of the buildings use water or food, so not that dificutl to implent.
Building need to have 2 water Storages, one for processed water 1000 (lts) and other for Raw water (2000)
production is 500 lts per day (in game time)
Hope developers like the idea, two many foragers die for a simple task as collectiong water and salt, we have already systems that increase soil ans Clay Quality so systems for Water and Salt seems needed.
