Having an impregnable village should be the goal of all gamers. Clash of Clans, and that is why in Mobailgamer we will tell you what is the best defense that you can use to achieve this goal.
The best defense?
Well, answering this question is not easy, because the defenses are each oriented to a specific objective that you must know in order to take advantage of it.
If we talk about effectiveness, the mortar is an essential structure that deals a lot of damage to ground troops, lethal against mages and other dps, but the META of the game makes most people opt for air attacks, leaving mortars and other structures like cannons with practically no major effect.
But at low levels you shouldn't worry too much about air troops. There, just focus on arranging the walls in an optimal way that protects the town hall, and placing the archer tower to prevent the rushing advance of the giants.
This being the case, you should focus on improving your air defenses to the maximum, in order to take down dragons, healers and everything that does not walk!
