Unity of the Elements

The map is very good, and I especially liked the scattered quests at the beginning; there's always a need for more of those. But I was very surprised when I read in this thread about the summonable elemental creatures. It seems like something has significantly affected the scripts. In the campaign folder, there were the large EU.h5c and The Beginning of the End.h5c files; after deleting them, the combat scripts in the battle with the Lord of Elements started working (both the wave and the elementals appeared), but in the battle with the phoenix, it still doesn't work. There are no errors in the console. I can't check Death and the Devil because I don't have the saves anymore. The auto-battle behaved interestingly: the undead and demons with a huge army fled after the first attack on them, although in a normal battle in the same situation, this didn't happen. I used it once because otherwise, the game would have dragged on. And the reward from the mages for killing the Three remained somewhat unclear: it seems that the benefit for the mage from the Sar-Issa set is that two items, not four like the others, provide a hero's turn speed bonus. That is, you can defeat a demon, for example, take the staff and robe, and ignore everything else. The ring and crown aren't very useful, and there seems to be enough mana.
