NHF – new heroes for Heroes V 3.1.

I have an idea regarding treasure rooms, although it has probably already occurred to you, but still, since the mod will be connected to NCF, could you add variations of guards consisting of NCF creatures for variety, or even create separate treasure rooms (recolor existing ones somehow, so as not to draw them from scratch)?
A few ideas for a special Orc:
-If the enemy town is within 1 turn of the hero, then a static bonus of +2 to speed and +1 to attack for every 2 levels (according to the biography, he is an experienced conqueror who knows how to motivate warriors with the wealth that can be obtained from the captured town).
-The hero can activate a special ability that takes away all mana (requires full mana) and remaining movement points (does not require full movement points). As a result, troops from Orcish towns appear in his army (troops are taken starting from the first slot in order; if there are no free slots and such a unit is not in the hero's army, then nothing happens to it, and the next one is checked; all troops are taken from the first slot, except for one, so that the hero, who is in the town, does not disband, if this is possible) (according to the biography, the hero has a very powerful cry that takes away all his magical power, but forces the town's troops to rush to him for reinforcements at full speed, as a result of which they will arrive there by the next turn (in fact, they will already be there on this turn, but the hero will not be able to go anywhere)).
-It is remembered how many creatures the hero has, and when visiting an Orcish town, a certain percentage of this number is multiplied by a coefficient, which also needs to be selected, and this number is the amount of money the hero receives; in addition, this counter of killed creatures is reset when visiting the town (according to the biography, the hero sells captured, wounded creatures on the slave market).
-Another idea with slaves: when attacking a unit, if it flees, instead of letting it go, the hero and his army "catch" them all or a certain percentage; in fact, the number of these creatures is remembered somewhere, and then when visiting the town, the hero will receive money for them, and maybe even artifacts.

The special abilities may not be very useful, but I tried to come up with something more or less different from what already exists.
