And to control them, you just need a hero even with level 1; the most important thing is that he has the artillery skill (the skill that allows controlling the ballista in battle)... and that's it;)[/QUOTE]
Regarding artillery - that' same clear, I just gave a hint in my previous message that it depends on the Hero, that's all;):)
As for the towers - I haven't looked at them particularly closely. I always comforted myself with the thought that it depends on the experience, attack, and other attributes of the Hero!
