or you could sell the raw herbs but i think you prob have a higher chance of being caught if you straight sell al your herbs. You could also craft the better shouldee enchants and sell those on the ah for a nice profit from your starlight ink. if you have a lot of free time and dont get bored easy you can sell glyphs on the AH ( i hate the glyph market)
18,75g for 3 ink of dreams. I dont have statistics but I usually get 9-11 shadow pigments and 1 misty pigment when milling, so like 32g per stack milled
