I conducted a small experiment. I took a hero with zero stats and placed him on neutral ground. I gave him a black dragon and pitted him against a neutral titan.
The results are as follows: the dragon won 13 times, and the titan won 7 times.
The most common outcome: the beginning of the third round. Both have 1-30 health, the black dragon attacks, and the titan predictably dies.
The titan killed the dragon in the second round, during its attack, so I concluded that if the dragon survives to the third round, the titan is doomed.
In twenty battles, the titan's morale kicked in twice, and he won. The dragon's morale kicked in once, and he won.
I didn't do any, excuse my Russian, nonsense with weight and defense. The dragon immediately flew at the titan, and the titan attacked the dragon.
Now I'll try playing as the titan.
