Before anyone else says anything, yes this is a necro - but I am allowing it, since it has to do with the same topic.
Which tier production scrolls are you looking for? T1, T2, T3? Because that will determine how I can help you.
T1s are sold at Ruby in Roumen. You have to click on the icon at the top for alchemy, then you will see the different items you can buy. If you do not see what you are looknig for, use the arrows at the bottom.
Some can be bought from Nina in Elderine using fame and others are only available through the mobs dropping them. Others cannot be obtained at all.
What do you see when you go to Ruby?
EDIT: Should have known lvra would beat me to the punch.
