The most challenging maps for you.

I figured out a way to deal with Salamandre, and it won't take as long as accumulating a huge army, although it will still be a bit tedious due to the need for repeated actions: Berserker + hit'n'run, especially since I have a hero who is an expert in fire magic (although, unfortunately, he's not my main hero). After repeating this about ten times, we will significantly reduce the number of fire birds and anyone else who "gets caught in the crossfire" by standing nearby, and also reduce the number of azure dragons. The biggest thing that's missing here is the Vulnerability Sphere, but it's forbidden on this map by the author to make the game more challenging for the player.
