I was playing for speed (for my own enjoyment) with fire magic, and my army just couldn't defeat the Minotaurs that month. It was a very, very long battle, in the style of "Vengeance is Mine" and other Chinese maps.
On the other hand, I'm not a very experienced player. Could you explain in more detail what you meant? Or maybe a screenshot of the army and the battlefield? Perhaps I'm missing something and that's why I'm struggling.
My comments in the map discussion, after which the last update was released, are under the nickname alex-st, if that helps.
I didn't fight these Minotaurs myself... I don't have time to play right now, but as others say, the idea of this approach to the battle is very beneficial. Equip the Cursed Armor + Sphere of Inhibition + Spirit of Despair, and of course, the Golden Bow, feathers, and bowstring for archer damage. The battle itself: Wizards + Snipers + Archangels + 4 groups of Cyclops. In the first turn, apply slow to the Minotaurs, and because of the Sphere of Inhibition, the computer can't remove it + the archers won't attack your snipers. You immediately destroy all the walls and towers with the Cyclops, and the Archangels run away from the Minotaurs within the walls. If you don't have enough firepower from 32 shots from the snipers and wizards, take a supply wagon into the battle.
