I summoned a Phoenix. It has elemental balance, by the way (so there will be a Phoenix with that). But your Phoenix attacks twice per turn (is that the author's idea?), but it helped me win.
The final is almost the same... the opponent spams phantoms and has incredible initiative! (even though I had 3 artifacts for speed: 2 rings and a staff + minor artifacts for 34% speed)! And this can lead to running out of mana (his imps go first and eat up half of your mana), you won't be able to kill them in the first turn - they have decent defense. I played with "Arcane Knowledge" and in the first turn, I controlled his imps and killed the imps - after that, it became easier, although you can only cast Berserk on his cave troll (strength), because he attacks you from the first turn. After that, he only attacks with his fists (but it hurts). Something like that.
P.S. There are a couple of bugs on the map: random mana regeneration when entering a Castle (it happened often), and one semi-bug (you still won't have enough money) - on the mountain where you buy elementals, one of the merchants (who sells them every day instead of once a week (stone elementals)).
I cleared everything 100%, completed all the quests - the most difficult battles (in my opinion) are the packs of elven troops (defense of the arenas in the Dungeon) - they have too much initiative - I left them for last before the final.
Thank you to the author for the game - it was interesting.
