Magnificent
Completed this scenario... No. For the first time since I registered on the forum, I am writing that I played a scenario with a Hero and did NOT complete it.
The gameplay of the scenario consists of sequentially winning battles with preset troops and hero skills. I won 7 battles and stopped at the fight against Zehir. The battles are difficult for me. The most challenging of the seven was precisely the seventh, against Eliah. Here is how it went: I tried different tactics 10 times and constantly lost, but on the 11th... I played the start of the battle very carelessly, but then luck triggered often and at the right time, and so I won, even with many troops remaining.
Regarding the battle with Zehir... I had an idea to play using an evasion bug, but they kill too quickly; luck often triggers for the enemy units. I am posting replays of all the battles I managed to win and the save file before the battle with Zehir. I suggest the author try to win this fight specifically from my save—that is, with the combat RNG that I encountered. If I see a victory, then I will admit that this scenario is indeed an outstanding piece of work, and the battle with Zehir is a tactical challenge in Heroes 5, the most difficult of all those I have encountered, yet very beautiful.
