The spell would allow the user to cast spell to allow him to see who is stealing and scouting. This would not be allowed in EE wars or system wars. The reason being is so that a strip can be caught. There are so many Spy accounts that can make gold without any risk of discovering who they are. Even the playing field. And please to give me that about " buy some towers " because spy accounts don't need to buy towers to see an attk build hitting you. Back to spell, the spell would cost a large amount say 15 mith and only last 30 min. Reason being is so that spell would not be exploited and recasted over and over.
support.... but devs should decide how spell is put into place such as 1). duration 2). cost 3). and whether evry spy action shows the name
