So you do not need to have 5 spies if you have tavern 12 (countermeasure Exchange) and still the enemy scouts will fail?
I think it is like, if you have got even one spy in your village you can still use countermeasure if outnumbered..
If you have got more spies than enemy scouts, you can see them coming to your village and prepare your countermeasures differenty or disable them.
If you have got less spies, you will not see any incoming scouts not even know that you were spied but countermeasure will stil do its job.
This way there will be no way of spying another village that has got the best one "Echange". Am I right?
Another thing is, what is tavern level 13-15 for? For HP and faster recruitment? Or is it related to successful countermeasure or anything?
But after reading this:
"The only way to defend against spies that are attacking your village is to have spies in your village yourself. They can uncover and defeat the arriving enemy spies."
I finally think that if you have got more spies in your village, you can kill more enemy spies incoming.
"You can also use countermeasures to deceive enemy spies. These are more likely to happen than a complete wipe of the enemy spies."
But it looks like you can not kill spies and countermeasure at once.
When can I recruit my 3rd, 4th and 5th spy?
