I am worried that this takes quite a bit of fun away. Traveling to a far city, especially to one that you are not supposed to be at with only level 11, is quite a success. And being able to do that not just onces but repeatedly, requires a bit of skill and luck.

And when you got enough money, that buying city scrolls city scrolls does not hurt you anymore, that is another achivement. But in order to feel that relief, you have to first suffer the pain.
