In 1.6, it was quite easy for me. Yes, at first, they attack, but it's more like flies – almost all of them are annoying but can't do any real harm. Then, we capture the Necropolis, hire a Necromancer hero, and improve our former territories. To take the Academy, I personally sent a Necromancer with an army, and then, with almost no losses, I captured it with Zephyr (I was afraid that everything would end, and we wouldn't learn the necessary spells). The rest is quite simple. The Necropolis faction can't escape the island – both exits are blocked either by Knights or Undead, and they can't really develop there either. It's a pity that a good idea comes too late. Now I'm going to build a Mage Guild in Novostrozhensk...
