Favorite hero from Dungeon.

What's that about? It consumes a lot of mana, and at high Spell Power, the lightning spell deals significantly more damage. No, I don't understand the people who start with Kyphra; most heroes are much more promising.

Okay. Let's assume other heroes are more promising. We take Kyphra, level her up to level 3, and get Diplomacy. We consider the 2nd hero as the main one. By the beginning of the 3rd week, there will be at least 1 unit on the map against which the probability of winning is very low. We give all the troops to Kyphra, and the neutrals will most likely join her.
In addition, 9 Minotaurs at the start is quite good.
