It seems to me she's not able to imagine an overly wide variety of potions. I guess she wasn't much into games when she grew up. It wasn't indicated at all she would have tried to create something but failed. Instead she was just using these simple ones. Although I do find it funny she stole everything, furniture included, that's the least the baron deserved. I hope she will be smarter in the next town. If nothing fancy happens again for a while, her whole visit to the town will become little more than a legend. In the end the baron himself never saw any miracles. Only a bunch of adventurers saw anything, and judging by this chapter, they don't want to cause her problems.
