The Ultimate Arcane Defense! Tower Wizards cast powerful area effect spells that target both flying and ground troops.
This anti-air tower is deadly against flying enemies, but can't target foes on the ground. Place it wisely to cover as much airspace as possible.
The Mortar can mow down hordes of enemies by the splash damage from its shell. Don't let enemies get too close to it!
Archer Towers have longer range than cannons, and unlike cannons they can attack flying enemies.
Cannons are great for point defense. Upgrade cannons to increase their firepower, but beware that your defensive turrets cannot shoot while being upgraded!
