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

Thanks to Fury, you can defeat troops that outnumber you. And Attack allows you to do so (in the campaign, I had an Attack of 24, while the other parameters were 5, 4, and 6. And even then, the 5 Defense was due to the Shield of Rampart). In general, Barbarians have been made a powerful race in terms of Attack (hooray). In one of the games, I gathered about 90 Cyclops, and in the final battle, only 2 of them died.
