I approached Kujin's development too carelessly. I didn't properly upgrade her Darkness Suppression or Spell Power. I was hoping for Gotay, because at the time, I didn't know that in version 3.1, heroes don't stop. I also didn't know that heroes equip random artifacts from the available ones. As a result, Kujin fought in the Armor of Enlightenment. I should have sold everything unnecessary.
Despite everything, Kujin won. Although, it took three attempts. First, I destroyed the cart and the towers. Then, I didn't use the catapult. The devils didn't summon anyone because they died early on. Kujin either used Horde Fury or Roar, depending on the situation on the battlefield.
The goblins initially disrupted the hero's spells, then fought in melee. Under Berserk, my soldiers often hit enemies instead of their own. The chieftains initially spurred on the cyclops, then fought themselves. When there were few of them left, they started spurring on the cyclops again. The Daughters of Earth initially cast spells, then fought. They ate one goblin because they ran out of mana.
I had 30 cyclops, 1400 goblins, 340 Daughters of Earth, and 20 chieftains survive.
