As a trade/profession/whatever one wants to call it you would need to use herbs to make potions or edible items to increase stats. So players would have to sell them or work together or however we want to do it. Maybe let them have two professions that work together or something.

For some items perhaps they have to go to a certain place like a cauldron to make some edibles. Others they can make in the field using vials they carry or just "mold".
