Let's welcome the new era of warfare!

I'm going to loosen up the rules(the fact that it isn't even written on the law book.) a bit for Conquest World.
If you all remeber, in the past I said to player you must declare war first right?( If i'm wrong plz tell me by commenting.)
Well, someone or some people do not liketo stir a commotion and end up attacking a mass group of army(target and allies) So let me (why me? I'm not sure myself, maybe you should ask Hem exa's Mr. Newt, I think he knows.) introduce you another method of attacking a player after seven years of tradition!Let me introduce you all the...

STEALTH WAR

• To say in simple English( or Real English, it means undeclared war.)
• That means you can 'surprise attack' somebody at 90% chance!
• Which is even important to have yor defence up and running the whole time.
• You can 'sercetly'(we all know this is no longer a sercet anymore) gather you and your allies' troops and try to attack a city without the target noticing.
• If you succeed in doing so, all attacking troops on your side will attack 50% more and defenders of the city will have 5%efence lowered.
• Now using spies on other lands are considered preparation of war.
• Actually, this method had been in sercet to sabotage other peoples base.Can you guess who? Try writing it in Comments and I will tell whether you are right or wrong.
