NHF – new heroes for Heroes V 3.1.

Belket's mechanics have already been implemented. Can we use this model?

Yes, of course https://yadi.sk/d/BYvMCX0A3ADFsk - I gave him a special Zoltan ability (blacklist), renaming it and changing the icon for the following reason: Belket's goal was to understand how Sar-Ilam moves in the Void; he began to study Sar-Ilam's teachings (thus rediscovering the teachings of Necromancy), and Belket clearly possessed a number of skills related to the Void. Sandro, a well-known Voidmancer, was merely Belket's student (I'm not denying that the student could surpass the teacher, but still). As we know, Sandro could influence the memories of others using Void magic (as he did with the memory of Mother Namtaru). Therefore, Belket has a connection to the Void (his specialization in G6 is "Lord of the Void"), and we can confidently say that Void magic allows one to influence the memory of the victim, so Zoltan's specialization is quite suitable, and it's not surprising that Zoltan has such a specialization - he is, after all, Belket's right hand. But duplicating special abilities is bad, so ideally, Belket should be given an individual special ability related to influencing the opponent's mind.

Hmm, my mod includes all the Demon Lords, and Ur-Hekal with Agrael's model, and others.

Ur-Hekal with Agrael's model... what do you mean... - IT'S NONSENSE!!! Firstly, he looks exactly the same as his minions (Cave Lords), except that he is probably the size of a house! http://ru.ashan.wikia.com/wiki/Владыки_демонов#.D0.A3.D1.80-.D0.A5.D0.B5.D0.BA.D0.BB - six demonic lords were created directly by Urgash in mockery of the six elemental dragon gods created by Ashai. That is, these are not just ordinary demon lords, but a counterweight to Elrath, Malassa, Silanna, Arkath, Shalassa, and Ilath - comparing them to Kha-Belekh (some ordinary archdemon who has risen to power) is somewhat strange
