The scenario is interesting, but I can't seem to win against Jessica with minimal losses. What should I do?
I don't want to lose my archers.
Theoretically, defeating her is a turning point in the scenario. The boss isn't particularly strong, and the blue player's power peaks with Jessica. Of course, there's also Vitka, but he's not that dangerous, actually. And you don't even have to fight Axel (I might be confusing the hero), who appears on the map at the same time as the boss. So, if Jessica has less than 30% of her army remaining, then everything is going well. You'll definitely defeat the melee boss using Darkness and runes. The main thing is not to delay.
