The “In Search of Power” scenario.

The scenario turned out to be not that difficult. Of course, I played on the "Hero" difficulty. There are a lot of resources on the map. While there were occasional problems with gold, even though there was a lot of it, there were no such problems with other resources, although I had to build 2 castles. The computer-controlled enemies running around from all sides were annoying, of course; they even took my first town while I was taking a Sylvan town, but it was manageable.
At the very beginning, I was given the Light magic, so I had a Warlock specializing in Light. It's actually the best magic for a Warlock. In addition to the initial defense, I also leveled up Logistics, Attack, and Luck.
