Final campaign - "Too Bright for Darkness [Campaign 7 - Mission 2]"

I played as the Necromancer, Anastasia. I completed this mission without any major problems. In the first and second locations, there was a catastrophic shortage of resources, especially stones, and later, money to buy all the troops, but nevertheless. The 200 units of Dark magic that I found in the ruins near one of the "Forgotten Tribe" castles helped a lot.
