NHF – new heroes for Heroes V 3.1.

Idea for a specialization:
Within a certain radius around the hero, the opponent has a chance to encounter a hostile unit, the size of which depends either on the opponent's strength, the day of the game, or the level of the hero with the specialization. As the level increases, so does the chance of the opponent falling into the ambush and/or the radius of effect.
Another option:
Once a week, the hero can set a trap (whether it's an ambush of troops, a reduction in movement points, luck, and morale, or the extraction of resources - something to consider) where he stands, the effectiveness of which depends on his level or the day of the game. When visiting the place where the hero who set the trap stood, the opponent, accordingly, falls into that very trap.
