And so ends the tale) Thank you to the creator) for the wonderful map and the timely assistance.

The main opponent (blue) didn't cause any problems, but the Swamp Dweller, Kreg Heg, with 84 attack and 82 defense, while I had 48 attack and 64 health, gave me a hard time. Thanks for the hint about the scroll; after that, it was just a matter of technique.
