I'm a newbie from a21, and I feel awkward about the water availability.
My thought was like this.
I have finally set up my campfire with my pot, I am able to purify murky water. Then, where I can get the bottled murky water? Just from the looting?
Okay, there should be another way. How about getting water from the pond with my bucket. Yay now I have water. How I can drink this? No?
Aha, there is a dew collector. I need a water filter to craft this. How to get the filter? Probably after I will able to craft my workbench. It's too early method for me.
Then, yesterday, I found and noticed the water filter was sold by traders and was not craft-able. And the dew collector provides me purified water. Fine😐
