NHF – new heroes for Heroes V 3.1.

Auto-translated

Warrior777

I think Shadi would benefit more from defense and evasion skills.

The summoning skill leads to leveling up the Mist skill, which is better than evasion from defense. And it's also desirable not to give them Earth Magic, defense, and so on. Some of the existing skills also need to be revised.

I can also suggest a few heroes from my upcoming campaign:
Inferno:
Urrg

Advanced Portal Mastery
Basic Chaos Magic
Fireball
Specialization: Abyss Lord: Cave demons, lords, and imps gain +1 to attack for each level of the hero. In addition, they gain +1 mana for every 2 levels of the hero (imps gain +1 damage for every 3 levels of the hero).

Do you already know how you'll implement the bonus for imps?

Warrior777

Tarot

Basic Sorcery
Soul Eater
Army of Imps
Demoness: Imps, devils, and lesser devils gain +1 to attack and defense for each level of the hero, starting from the first. In addition, they steal 1% more mana for each level of the hero.

And do you know how to implement this one too?
P.S. Multiplayer is not single-player.
