Are you sure you want that tower to fight dragons?
If they\'re supposed to be able to fly you\'d be a clear target for them, they\'ll see you easily and you\'ve nothing there to avoid an attack.
The best strategy, attack the dragon from the mess that is the amount of Hydlaa houses for anyone that is seeing the scene as a bird (i\'m sure you have an expression for saying this, but, unfortunately i don\'t know it).
The hard the dragon can know where it is attacked from, the lower your chances are of ending bursted.
