I play on hard difficulty. That's why I say that Irina is a tearful mage, and she has no problems in battles, because the AI spends all its forces on killing summoned creatures, without touching the main army! Only killing her with magic, nothing more! BUT HOW ABOUT A WARRIOR?? He won't be able to summon anymore, and the main attack will be taken by the army. And there are fewer troops by definition, and resurrection will not be as strong as for a mage!
I killed Michael on the first try. An interesting character, especially his ability to deal 12500 damage))) Yuko-ono survived the entire duel))
