The essence of the tactics when playing as the Dark Elves.

It's strange, but I don't think Leto is such an overpowered hero, at least not in practice. In theory, it sounds good, but in the game, it often turns out to be the opposite. First of all, he desperately lacks mana. As Mdance said, you can mitigate this in the late game with education or spellcraft, but in the early game, it's just terrible. At the first levels, you can only cast Plague once, and its Aura triggers very rarely. And I don't understand why he's even better than the Mechanists at clearing out enemies... Also, why does he need Dark Magic, since it requires a lot of mana and is designed for those who have problems with spellcasting, but Leto has the opposite problem – he lacks mana.

Leto shouldn't try to grab a piece of the center; instead, with as much mana as possible (there are wells before the bridges), he should attack the enemy and bombard them with Chaos. For this purpose, Kifrah looks optimal.

Explain in more detail why Kifrah specifically. I think that even Erin (if you already have witches) would be better in this regard. By that time, she will have already leveled up her Chaos magic and attack, and besides, her witches will respond to her spells with their own volley. And thanks to her attack and tactics, her troops will also deal excellent damage. And if you also level up her Summoning to Fire Warriors, there won't be any problems with the Mechanists either. I think it would be more effective to focus on leveling up Summoning rather than Chaos. Level up Chaos to Master of Chaos, and Summoning to Fire Warriors – I think this would be an excellent combination. However, I have a strong suspicion that I'm missing some very important factor
