Air Defense

  • Summary
    • The 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, or interfere with them in any way other than potentially distracting them from attacking a more valuable target (e.g. the Town Hall).
    • The Air Defense is unlocked at Town Hall Level 4.

Mortar

  • Summary
    • Mortars are the player’s heavy defenses. Whenever an enemy comes into range, it blasts out an explosive shell with a low frequency “ping”.
    • Mortars shoot long-range explosive shells every 5 seconds which deal devastating splash damage to every unit within a small radius of the impact point. Their splash damage, combined with their long range, make them deadly weapons against large groups of weaker enemies such as Barbarians, Archers, or Goblins.
    • A Mortar’s major disadvantages are its inability to attack troops within 4 tiles, its low rate of fire and low DPS which makes them less effective against high-health troops.
    • Due to the fact that the Mortar’s shell takes a while to reach its target (over a second at maximum range), fast troops like Goblins can easily dodge its attack if they are moving when the Mortar fires.
    • Mortars cannot target air troops.

Cannon

  • Summary
    • Cannons are the first defensive structure that a player builds at the start of their Clash of Clans adventure.
    • Cannons are both cheap and quick to upgrade at lower levels.
    • Cannons can shoot any ground units, such as Barbarians, but not any air units, such as Dragons.
