I crushed 20 stacks of elementium ore two nights ago. I got 18 nightstones. Funny thing is, I had such bad luck with nightstones previously that I regularly had to buy one or two for the JC quest.
I also have accumulated nearly three stacks of amberwhatever (the yellow gem) but only one stack of the comparable orange gems from the crushing I've done in the past few weeks.
I am convinced that all of our experiences with this point to the existence of a scientifically provable formula which I will give the name: Retrograde Numerical Gestationalism. Also to be known as RNG or cynyck's Postulate. I don't know what a postulate is, but if mom were alive she'd be so proud of me right now!
"the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country."
Hermann Goering, April 1946.
