Well, Now I'm a Cauldron Master, atleast the text says that when I'm trying to buy a new recipe. But where can I see this? Isn't it viewable at my profile

OK, found it myself It's that little potion near my avatar

Yup, I'm a Cauldron Master also! Gratz on your achievement!

where do you go to find the potions that don't fit on your first page? I won a new recipe on the wheel but I can't find it in the recipe list.

Scroll down and you will find them
