Warlock – “Cultist” [Campaign 4, Mission 3]

Hristana, there should be 3 red heroes. They appear after capturing the 2nd, 4th, and 6th castles. If there were only 2, it means the enemy had at least 3 castles. To prevent the enemy from leaving the last castle, Shadia should block it. I constantly provided her with reinforcements from all the castles.
