What skills should Necromancers take when facing Orcs on a very large map?

darkness is also useful because cursed land effectively suppresses bloodlust, usually in Orcs. It typically takes two to three turns to reach Necropolises, depending on the terrain; during this time, the initial bloodlust is burned out. Once, I fought Orcs on a map where there were only two narrow passages in the rocks between the two armies, right in front of my troops. I blocked these passages with a wall of fire, and considering the cursed land, the Orcs started fighting without bloodlust and were weakened.
