Air Defense

Air Defense is a powerful Defensive Building with a very high damage per second, capable of defending against flying units. Air Defenses can only target and shoot one air troop at a time. It cannot harm ground based units. Air Defense is unlocked at Town Hall level 4.

Defensive Strategy

• The Air Defense has an excellent range and a very high damage per shot. The common strategy for Town Hall 8 and above is to position them in a wide triangle (or diamond, once the fouth Air Defense is available) around the Town Hall.
•  Lava Hounds aim this building first, so make sure you defend it well with other defense which target air troops. Single-target Inferno Towers are most effective, if you have them. If not, other point defenses such as Archer Towers and Hiden Teslas are recommended.
• Keep your Air Defenses behind your first lines of defense (e.g Cannons and Archer Towers), ideally with a Wall in between. Doing so will prevent a large Giants or Golems assault from quickly destroying the Air Defense and allowing a Healer to be deployed earlier in the battle. The longer it takes the Giants to destroy the Air Defense, the more time your turrets will have to thin out their ranks before a Healer can be safely deployed.

Offensive Strategy

•  The Air Defense is a natural target to attack first. Healers are vulnerable to the Air Defense, destroying this building with Giants before deploying Healer is recommended. They are easily destroyed by any ground based troop, as they cannot fight back.
• It is highly recommended to keep Balloons away from Air Defense, as they are capable of destroying most Balloons in one or two hits from a great distance.
• A great way to overwhelm the Air Defense is use a large group of Minions, since the Air Defense can only target one air unit at a time.
