There is sticky up in this forum named "Frequently Asked Questions - Read before posting

So I was just wondering - is there any other public world map (Plymouth) you use?

And since, I've gone so far and made a new topic here, I'd like to ask another one:
Can anyone explain the concept and practical part of purity of things in Salem? How can you influence it or craft or grow or whatever?
Everything I found - is that purity is good for stats of items & that you can make higher purity items from higher purity material (so finding higher that 1.0 purity mine is good).
But how do you get higher purity mushrooms for example? Does the particular area influence on purity of stuff found in it?
Thanks!
