I loved the mechanics to make the potions in the map with the ingredients, but it is repetitive.

Advices:

- You don't need to do the potions exaclty how the recipe says, while it has the same effects that's all right.
- If you haggle you'll obtain lower quantity of Popularity Points. Use this options always with the merchants in the most difficult option that you have.
- Buy all the ingredients with the normal price or on sale from merchants, always buy rocks.
- There are exquisite clients that will ask for potions with specifics things, I recommend sell them potions when they want an extra effect in the potions, use the options 'continue brewing from here' and add the closest effect, usually they'll be happy. If they ask for something so specific end the dialog and sell to the next client.
- If you didn't get the plants in your garden don't worry, they will be there on the next day. Collect them is important in the earlygame, at some point of the game you won't need them.
