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

you were talking about Divine Vengeance here... saying it will solve everything.
Apparently, you've taken something into account that I don't know, because to me, it sounds like nonsense. What kind of spell is that, if it's light magic? And such a high-level one.

For example, the fact that you need to upgrade Cursed Land (it deals 12 damage to an Orc) – so why upgrade it?

Here, they were talking about the fact that it needs to be upgraded to reduce one of the Orc's Fury levels.

Besides dark magic and sharp intellect (logistics + education), you can also take attack for the Necropolis, for tactical reasons, to reduce the number of troops that reach the rear, or defense to hold out longer until the Battle of the Day.

Why Battle of the Day? oO
