Tunguska war dragons are very useful for fights because they are specially trained for fighting and for very lof flights.
-Their fighting abilities are awesome, so they will be useful in a combat -They are raised from the egg, so they have a very strong bond with their riders. -They are trained to endure long flights, so they can fly almost a week without stopping for rest.
Their big disadvantage is their inteligence. As they were raised from the egg, they are useless without their rider in battle. The rider gives every order to the dragon, so they will obey ONLY to their rider. This is possible by the scent of the rider, the dragon has passed all its life with him, so they will recognize their scent.
