Thank you. Could you elaborate?
I only play against the AI on difficulty level 4. I place several of them on a large map. So, it's hard to say who I'm playing against – they're all different. There are both magical factions and those that aren't.

I have a more specific question, or rather, several.
I don't think the "Spellcasting" skill is very suitable for a Necromancer. In what cases is it better to take it?
I also wanted to know more about leadership. Is it really useful, and if so, in what cases? After all, it's a lost slot... So, I'll have to sacrifice something important.

Also, regarding Luck. It's a good thing for a Necromancer, but is it an alternative to Attack?
Yes. Ghosts will become very good, and magic resistance will increase, plus -1 to luck, which is good in the case of a Dread Knight. But still, luck is a random thing, while Attack always works.
