I have confirmed for myself that the color of the empty determines what memory drops try for yourself and i think that this color changes as determined by the day so try and farm on watersday
Heh.. I've decided to farm these soon. The prices on Kujata are about 300k/stack if I remember correctly. Still, not many farm this. I don't really see why. I even get a slight exp-bonus while doing it. Not much, but usually I don't get anything while farming. ;D
Does anyone know the best mob to get these from? On Ramuh sombers are about 200-300k a stack. And water animas themselves are getting overpriced. Any help would be much appreciated. I even tried to hire a paladin to farm 3 stacks of somber memories for an astral rope... he could only get one stack of somber memories and alot of everything ele.
