I can't seem to find any Purifying Solutions anywhere in Drezen or around. I bot out all I could find in Drezen already witch wasn't much. This is causing me problems in the game because I can't cook anything. Does anyone know where I can get some Purifying Solutions in this game?

This is a real pain in the ass!
Nope, There are no Purifying Solutions in this game so far. They got to add some so we can freaking cook a MEAL!
