It went smoothly. I leveled up a lot. I took two castles at the top and three at the bottom without any reinforcements, using only what I had at the beginning. Summoning dark creatures, draining life, and sometimes mind control allow you to take almost any army with minimal losses. I played on normal difficulty. In general, it seems to me that Necropolis is a bit overpowered here, especially with the resurrection pillar. Guys, tell me, are there only four missions in the campaign? It seems a bit unclear.
