I disagree about the Darkness Shield. It's effective against Necromancers and should definitely be taken. Just the fact that the Necromancer will lose the ability to control Cyclops and cast Berserk for only one turn is worth it. Not to mention that his magic will decrease significantly. Let's say if the Necromancer has 20 magic, thanks to the Darkness Shield and "Power Against Magic," we can reduce it to 12-13. And Shamans will also make his life difficult. As a result, Darkness will be severely weakened.
Also, I disagree that you should take Fire Fury in education. This skill is quite questionable. And in the case of the Necromancer, it's definitely harmful. The Necromancer, with his mass Darkness spells and Liches with their cloud, will greatly disrupt your Fury. And not just disrupt it, but make it 1.5 times stronger. And instead of getting benefits from this skill, you will only get harm.

I haven't checked in a long time. But I think it definitely removes the effect. I need to play sometime and recheck.
In general, if we're talking about skills, it's desirable to take Fury (all levels), Logistics (the Necromancer develops quickly, and you need to keep up with him), Attack (the main Orc skill), Leadership (definitely Battle Fury), and then choose from Darkness Shield, Luck, Defense, Mechanics, and War Cry.
Don't forget about the War Cry that increases morale – it's very useful. Even increasing morale by +3 will allow you to always have it positive, which means "Battle Fury" will always give you Fury points.
