The main opponent was Galthran, and he always had a numerical advantage in troops, but I developed several magic heroes and constantly harassed him, making him exhausted and giving me time and space to develop. I trained several heroes with logistics skills, plundered strategic points on the map, and then obtained spells like Recall and Teleport. Although the opponent had a strong army and even acquired the Magic Carpet, he couldn't break out of the area he explored in the first three weeks and could only watch me develop, eventually leading to his defeat! thx
