I looked at the map script, and the number of troops in the hero's army doesn't depend on the difficulty level.

Moreover. The opponent (in my unenlightened opinion) is virtually invincible (especially for Giovanni and on the 3rd week), and it's also impossible to run away from him with his "movement speed." Besides, killing him is a mandatory task...
And - about the skeletons. I understand that gathering 400 of them is as good as impossible; there aren't that many peasants in neutral territories. Waiting for them to grow and then for enough dark energy to accumulate? By that time, the yellow faction will definitely arrive:rolleyes:
