Setting up Multiple Accounts
Much easier to do on Android, but can be done on iOS though it's a pain.
Another idea is to use an Android emulator such as Bluestacks to run CoC
your PC with a second (3rd? 4th?!) account.
General Tromador personally uses the Android method for his villages, and
has also used Bluestacks. He has also used them for other SC games like
Boom Beach. He has no experience with iOS.
