Blue crystal

After three attempts, I finally managed to complete this challenging map: I played the latest version with a human hero (a knight with a machine gun), and finished in 119 days (I received a fire dragon). The biggest difficulties were with the guardians. It turns out they are easier to defeat when choosing a troop restriction. It's a pity that the player doesn't get to choose the hero's troops; instead, it's determined by a method known only to the author. In one case, I fought only with archangels (53), in the second with archangels and adepts (53+407), in the third with paladins and landlords (62+1054), and in the fourth with adepts and archers (407+594). I leveled up the hero's mechanics, luck, defense up to Battle Defense, light up to Wind, and logistics up to Cunning. For the fire elemental (the strongest), with its immense chaos magic, unknown spells, and initiative-based archers, I had to change defense and mechanics to darkness and sorcery. In the end, with difficulty, I defeated him. In my opinion, the map would be good, and might even be comparable to "Red Crystal," if not for the annoying finale with hero sacrifices and running back and forth. By the way, without the author's explanatory note, it's impossible to figure out everything. As for future suggestions: test the map, including the final battles, and then release the version. Nevertheless, thank you to the author for their work.
