"Necropolis" - changes to creatures of levels 6-7.

1. If the death rate is three per week, their health should be 150-170, damage up to ~50, and the attack and defense parameters also need to be adjusted. (The Banshee has high defense; it should be reduced by 15, and the Herald's attack can be slightly reduced by 5).

I believe that if a Faction has a building that provides a bonus at a certain level, it should be a top-tier bonus when the building is constructed, and not equal to other bonuses. Otherwise, it turns out that the building is a weak point of the Faction, not a strong one. Consider this: spending an extra day and a lot of resources on an extra building just to equalize the tier with other Factions. And even then, the building only increases the subsequent bonus, starting next week, but not the one that was built before it.

The "Mournful Wail" has become incredible, and given that there are three of them per week, it's incredibly incredible, but it has become more useful. If everything remains as it is, no one will take the Herald, and everyone will take the Banshee. I suggest replacing 10*(10-BD)*count*range with 7*(10-BD)*count*range (considering that there are three of them per week, it still remains very strong).

And how is it so incredible? A normal creature of level 7 would deal that much damage with a regular attack, considering the difference in attack and defense. And it does this while moving, not standing still, when this ability can only be used once every 15 years. Even the Burning Breath of the Red Dragons will be more effective, although there the damage bonus is only +50%.
