"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

I replayed it 100 times, but I finally completed it. In the previous mission, you need to equip Wolfsten with a set of Sar-Issa armor, otherwise it will be very difficult. And, of course, you'll need a perfect knowledge of runes. Frida should be at least level 20, preferably 24-25. Instead of Kujin, it's better to send Gotai and don't forget to take 900 Cyclops. It's better to develop Zehir's light and dark magic skills. I completed the battle with Biara mainly using "Subjugation," "Holy Word," and "Divine Vengeance."
