That's understandable, but in that case, the morale of the units will be negative, and this ability will only do harm...:confused:

Yes, but in the first mission for Arantir, Ornella will be his ally, and she will be a knight, and the penalty won't be very large, because to gain empathy, you need to develop leadership to the 2nd level, and the morale will be +2, and the morale of the squads will only decrease by one unit, and if a necromancer leads troops of evil races or neutrals, then the morale will not be significantly affected. Plus, to gain empathy, you need to acquire 9 skills, so it's unlikely to make a necromancer's life easier. They added it so that people wouldn't complain about why everyone else got standard abilities, but necromancers were left out.

It seems to me that the "sacrificial altar" is a useless thing for evil races:
Orc - can sell creatures in the city for money
Necromancer - they use "non-native" creatures better than anyone else, which is why I love necromancers))
Demon - the same altar, but in the city
Dark Knight - increases growth in the city
And the fact that they give little experience for creatures, means that they can be useful.

Well, if there's nowhere to put the creatures, it's better to sell them for experience, especially in a campaign when you've almost won. You can sell creatures, but it's still better to sell artifacts
