NHF – new heroes for Heroes V 3.1.

Regarding the bio. Galtran's specialty is enhancing necromancy, essentially. And we need to consider that he studied necromancy more deeply. And there's nothing unusual about raising the dead for a Necromancer. That is, it's not a skill or a spell.

Necromancy is not a spell, but a skill (ritual). It has nothing to do with raising the dead (a combat spell), since the latter is essentially just a special version of resurrection: we revive corpses into corpses, while with the living, we temporarily extend their life; necromancy, in contrast, transforms dead living beings into living corpses, i.e., it changes their quality. In addition, necromancy also doesn't consume mana.
