NHF – new heroes for Heroes V 3.1.

Necropolis: If a hero kills 4 or more basic creatures of a certain level within a week, the growth of creatures of that level in Necropolis castles increases by a certain amount, for example, by 50%, or a formula could be devised. (In the biography, it could be written that the necromancer, realizing that he does not possess the necessary amount of dark energy and necromantic skill to raise all the dead, uses magic to send them to a castle, where local necromancers revive them and add them to the hiring pool).
