NHF – new heroes for Heroes V 3.1.

It's definitely possible, preferably after the 0.82 version is released.

Okay, since the specialists I described earlier didn't quite fit, I'll continue.

Hellish Healer - Starts with the "Plague Tent" and its effectiveness is doubled and increases with each level.

Bastion - Possesses skilled defense, and half of the hero's attack is converted into defense.

Money Eater - Has the ability to consume money, in exchange gaining experience.
