The special ability from the post with ideas about traps on the map is quite interesting. Why hasn't it been implemented in the mod yet?

:o
A little bit of everything.
If there's a desire to create such a hero, I'm all for it. But other plans are currently a priority.

Could it be possible to implement a specialization for Inferno that allows them to deprive the opponent of a portion of their mana before battle, depending on the hero's level?

A similar ability exists for the Necromancer.
Besides, it wouldn't be useful for Inferno, as they already have Imps.

Thanks.
If I unpacked NHF_0.76.pak using a zip program, is that correct?

You can simply open it with an archiver, make changes, and save it.

I haven't checked all the new features of the mod yet, but remembering the "fast turn" mod and its 8 abilities: maybe a specialization for an additional ability wouldn't be too imbalanced?

Based on the current concept, most people want a mod that focuses only on heroes, without changing the game's balance. There were various innovations in the past, but people didn't like them.
Download version 0.70f from the folder with older versions. But even there, such a thing wasn't planned.

I'll reveal the secret of the next version - 0.77:
There will be a second, expanded version of the mod that increases the list of heroes to include all existing ones in the game. Absolutely all of them!
This version will be obtained by installing a small patch (of course, if desired) in the form of an additional file in the data folder.

Pros: All campaign heroes and NHF will be available.
Cons: Imbalance, "hero clones" in terms of special abilities.
