You might have the material for two, perhaps even three spells mixed into one, to its detriment. Cities are IMO far more complex than the wilderness, and so are the ways to interact with them. BtLF is far simpler in its core idea than your spell.
A spell that makes you feel like a savvy native in every city is not thematically the spell of a wilderness dwelling hermit but that of a traveler who visits many cities. Do you want to make the city bearable to a wilderness dweller, or do you want to query a new, foreign city for its secrets, power struggles and hidden places?
...I sort-of want to try writing up my own interpretation of these spells (hence the wordy post). Not gonna try to steal your thunder though, so perhaps in a month or so
- The sorcerer does not need to eat nor rest
- The sorcerer knows, where, in the city, what she needs to find. If she needs to find food, she will find a shopping mall, a homeless shelter, a soup kitchen, or a place where they dump scraps. If she needs to find information, she will know the location of the local library or university, and etc.
This strikes me as a strange combination and removing the need for rest or sustenance is not really thematically fitting or playing into the spells concept as a whole, and arguably too strong.
It is sort of an auto-resolve that removes the need to get out into the city and actually get your food and shelter, and you know, interact with the city. Also it arguably makes the spell last forever as long as you remain in the city.
"Knowing" is fairly arbitrary and either too weak - you need knowledge so you find a random library - or too strong - you know the exact location of the one book in the city that has the knowledge you seek.
Limit or specify the effect somehow. It might need some mechanics. It can be a spell by itself.
The final effect is also not all that well specified in my opinion, and it automatically resolves the plot-hooks that it offers.
If you know exactly how to dress and where to find the clothes you need, your outfit should still matter. You give the player the tools to blend in but then also remove the need for them.
Knowing the customs and being accepted regardless of your clothes are also two rather different effects, one of which should have a flaw/be resistible. It most certainly lacks Keywords and actual rules.
It should not be capable of forcing a Solar to ignore a crazy hermit in a loincloth.
I personally would remove the Illusion and the removed need for rest and food and improve the scrying aspect. It could use some mechanical and thematic depth, but it can easily carry a spell by itself if done well.
If, on the other hand the thematic focus is foreignness to cities, as you postulate at the beginning, then perhaps a focus on avoidance an illusion might be better, possibly also a focus on interacting with city animals, eating spoiled food without problems and finding safe shelter away from sight - make the city interact with the player as a differently looking wilderness.
...also the doubled movement speed is just strange as it is written, and would look really weird from a thematic standpoint. It is one thing to know shortcuts, it is another to become the Flash.
