The Necromancer's Path.

The scenario is really tough, especially the final boss on the mountain. He has a general vampirism ability and some debuffs, like a counter-spell or something similar that prevents raising the dead! It's like a blacklist. Giovanni is a real pain; he didn't lock him up, and I managed to defeat the final boss and the zombie knight, but I was one turn short. The mission was completed the next morning, but I had spent so much time on this boss. I had to revert, lock up Giovanni with a secondary character. As a result, it took 120 days on the hero, and I got 2772 points, but I had to spend about a day on the scenario, thankfully it was a weekend. Thanks for the map; a brief walkthrough with more hints for the quests would be helpful.
