HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Is it impossible to have a battle between players in the hotseat mode (3.45), or is it just me?

exclude the artifacts boots of levitation, dolphin keychain, and captain's hat

These are definitely detrimental artifacts, just like the artifacts for diplomacy, eye, and in many ways - the skills of ballistics, scouting, obedience, magic, and water. Obelisks, imp, cartographers also only hinder. Remove the useless skills from all heroes, and give them neutral offense or leadership. It will be a great game, almost like CRISIS111, where you can be invulnerable, elusive, invisible, or self-healing - all roads (1 item) lead only to a cutscene, the balance is perfect. But what is this nonsense, one gets an elf lair, and another gets golems, the rights of the "negroes" are violated, we call Mumburu Bumburu - democracy is in danger!
