This world will burn to ashes!

Yes, especially on the Hero level)
I wanted to create challenging battles despite the main hero's progression, so I forced you to fight not only with Raast...

Dear author, you wanted to "create challenging battles despite the main hero's progression," but, forgive me, you created something of a mess! If WE had wanted that, or if it even made sense, we would have started playing a completely different scenario! Just explain to yourself the point of leveling up a hero, leading them across the entire map, only to be given some cripple with a stick and forced to assault a Castle? If the map were terrible, I would understand that you have some issues with logic, but the map is simply excellent! No bugs (minor flaws don't count), purely a rushing map as I like, I had to think through the strategy, protect my troops as the apple of my eye, think, and in the end, get two wounded troops, on whom the victory now depends! This is simply an epic fail, how you screwed up this scenario in the end. Okay, I've already come to terms with it, but explain to me what you wanted to achieve when I dive into the portal at the end, a window appears with the new hero Nimues, and as I understand it, I can transfer artifacts and troops to him for the battle. But the next action is that I assault the Castle of Daleb! Daleb, for crying out loud! Why her, and not Nimues? I'm not even saying that Nimues has troops of other tiers (you can reload and give him others), but Daleb? Why is there no way to give her troops, artifacts? Why should I even transfer anything if I'm fighting third and don't even know what I'll need? Why does the victory in the scenario depend on the first of the three battles at the end, and the first battle is conducted by Daleb, to whom nothing can be given? Why couldn't I level up these two as I want? Why is Nimues so castrated? Just a bunch of whys and wherefores. In short, to say that I'm frustrated is an understatement. I managed to pull through the battle with Daleb after many reloads, but the scenario is meaningless and merciless. The only good thing is that I had a good fight for two days.
Advice for other players. When you descend into the last Dungeon at the finish, you will be ambushed by the last hero of the Order faction – this is the last battle, the Finale! Then the circus with horses begins. I agree with 13ga on many points.
Criticize – suggest.
Advice: to the author... after the heroes are released from prison, they are given artifacts (this is more than enough), there is no need to call them into battle. There is simply no need. And to the players... Soul Eater and Hellfire are a must! Protect the Imps! (they determine the amount of mana drained from enemy heroes, losing troops to various rings of cold and death is bad), protect the horses (they are the main damage-dealing stack). Machines with a tent are a must-have, as well as education with a rooster, so that you can learn low-level spells, which are not easy to find because they are random. I chose Darkness, but you can also choose Summoning (Phantom, Wall) + Darkness. If you get Light, that will also work. You can have two schools, but not Chaos, because you can only increase the spell power to 20+-. Imps and horses of the second tier are better than the first, it is more profitable to scare with the second than to damage with an aura. I had to upgrade the Succubus to Temptresses because the Night Hags didn't want to cast Confusion (a must-have) on you, but just hid or walked around.
