Near the castle, there was a dungeon with 20-49 Kentaur units. I went there, cleared it out, sacrificing a tent and a minimum number of my own units, and found Tamika, a level 5 unit with excellent stats (experience in Necromancy, advanced attack, and wisdom). I decided to use her for non-critical attacks. On turn 115, I saw that the AI had killed my gray companion, so I knew a quick confrontation was coming. On turn 117, Charna arrived with a small army, and I just laughed. At that point, I already had 150 skeletons. I should have retreated, but instead, I took a detour, avoiding the cleared path. Along the way, I was supposed to capture a fort guarded by Nagas. In the loot box, I received the entire first-level upgrade, so I wasn't worried. I drove Charna away, but then Ciel arrived and destroyed all my recent gains, capturing my main castle. However, I didn't panic. I rushed back and blocked Ciel's retreat. I thought that if she stayed in the castle, I could take both the main castle and her gray castle, but instead, she attacked me. She attacked with shackles and killed Ciel. Then, I retook the castle, and my opponent surrendered because it turned out that he had a maxed-out unit in his crypt, and they had killed his psionic units. Thank you for the game!
