Puzzle by Antoshka.

Today, I received a save file for a puzzle that was created by one of the best Heroes of Might and Magic III players in the world (in my opinion). At one time, this challenge made many of the strongest players in the CIS region rack their brains. To solve it, you need to know a lot of things: how to speed up, how to avoid penalties on rough terrain, how to summon demons, how to dig for the Grail, and much, much more. Take a look and try to complete it. You need to complete the entire map in 1 day! Score 500 points. Those who manage to solve it, please don't post the answers right away. It's a very good tutorial for those who want to learn how to play Heroes.
