What is an Imperial Standing?
An Imperial Standing is an item you can find on the first page of the Miscellaneous section of the Shop.
The Imperial Standing allows you to upgrade a building from level 9 to level 10. Without the Imperial Standing you are not able to upgrade any of your Buildings to level 10 as it is part of the requirements to do so.
Once the item is used it cannot be returned. Make sure you choose which Building or Field to upgrade wisely as the Imperial Standing will be lost if you cancel the Build or Demolish the Building after it has been applied.
You can obtain an Imperial Standing by purchasing it in the Shop for 100 Gold or try your luck with Fortuna's Gamble
