Farming has never been so easy! In the early stages of this game, when you don’t have many troops, it is difficult to fight other players without them wiping you out. When cities with the 7 day protection bubble haven’t been active since they started, it will show that they have a “bubble” of protection over them even past the 7 days. The way to bypass this protection, is by using your muster field to attack their coordinates. This will only work on EXPIRED protection bubbles that have become inactive.
