How to “freeze” a Castle in Throne Wars
While this can get complicated, here are the basics. The idea is that while you are attacking your enemy, he can’t remove his troops from his castle. This means that the troops are there to stay for one full 5 minute round. To take advantage of this, you can attack again and again immediately following each 5 minute battles. This keeps your enemies troops “frozen” in that particular castle. This can give you time to form a large attack and destroy all of his / her troops while taking few looses.
