NHF – new heroes for Heroes V 3.1.

Dyrman, that's a bit too complicated for me to grasp.
Anyway, as I understand it, it's still not possible.

Perhaps it could only be added to the expanded version, just like with Dreylan, if a basic version of the special ability is needed, and even Arafel with Raialag's special ability, because the expanded version is unbalanced and has many repeated special abilities, and it's more for single-player games.
