I'm sure a lot of other players have had this same issue, how do you craft tonics for Act 2. I understood the logic for the Volatile Tonics, Purchase 5 greens to get the blue, Purchase 5 blues to get a purple- Easy. But the enriching tonics are not showing the green to recipes to purchase. Some have randomly shown up and I have done but I cannot see the logic or needs to make more green craftable. Can someone please explain what needs to be done for the green tonics to become available. Or can Bungie on Act 3, please show what the tonics are and what the player needs to do/get to craft them, not hide them without an explanation.
