Posts from About changes and/or combining Hero Specializations. Auto-translated

The main question of the topic is: how much and to what extent can a Hero's Specialization be changed (beyond the "RPG file")?
The main points at the moment are:
1) Is it possible to change/replace existing specializations themselves?
2) Is it possible to supplement existing specializations, at least with effects from already existing other specializations?
3) Is it possible to create new Specializations from scratch? Or do they need a "template" like creatures, Abilities, and other things, which cannot be easily created?

* There is no question about whether it is possible to change a hero's Specialization. We can already give, for example, Rutger the Specialization of Railag. The point is about changing the specializations themselves and their effects, which they will give to the hero.

For a simple example, let's take the following:
Let's say we want to create a new Specialization for Nibros based on existing ones, specifically by removing his bonus to Luck and adding Krag's Specialization. That is, as a result, we want to get the following effect.
"The enemy cannot use Tactics. At the beginning of the battle, your hero performs a special attack, and the strength of his attacks increases by 5% for each level."

Or another example, where we might want to create a Specialization for the Order based on the Tent. Based on Kaspar's Specialization. But since the Plague Tent is not available to humans, we want to give another bonus in compensation. For example, part of the "Perfect Knight" Specialization or a permanent Divine Strength from Isabel's passive ability.

Changing specializations is only possible by modifying the .exe file.
Or by using scripts.

I understand that scripts will only work within a single map, not the entire game, right?

But if we're talking about the version with scripts, it would be good to have more details. This could be useful for one of my projects, to create more interesting Hero Bosses, without being limited to campaign-specific overpowered abilities.

The problem with NHF is that the scripts must be enabled on the map, so the map files are run through a special program before the game.

As I understand it, this program itself is in an executable file, and it runs a set of maps through it. If you need to add heroes from NHF to your map, you just need to add it to the executable. As I wrote earlier, complex special abilities, like the one mentioned above – a combination of Nibros and Krag's special abilities – cannot be created using standard scripts.
In my future map for Kaspar, I initially wanted to give him a combined special ability – his tent ability plus a special ability for liches (like Lucretia's ability for vampires), but I abandoned this idea because it cannot be done using standard scripts, only through manipulations with the exe file. Maybe I don't know some nuances, and it can be done more simply).

lol, I guess I'm stuck in 2016. Back then, there was a separate patcher for maps.

Maybe I'm not the first, but I had an idea for an experiment. I was recently messing around with poisons and noticed how the amount of Poison damage is defined for Assassins and Manticores. (I used to think that the latter just had Animal Poison, like Wyverns, but it's actually the third type...). In short, the question is, can I, knowing how or what, enter new values into the RPG file? That is, hypothetically, Hydras have Regeneration, and it is defined specifically as a Regeneration value for Hydras, and not Regeneration as an ability. What if, for example, I try to do the same for my Cyclops and set a different value? And if this works, can I enter the missing data for Hero Specializations and Skill effects in the corresponding sections?

*Of course, I will test it, but I am also interested in the opinions of others (I don't think I'm the first to think about testing this, though?)

Perhaps not intentionally, but I achieved something. This happened during the restructuring of creatures in the League.

It turned out that creature specializations are tied not to the Tier, but to specific "crates." That is, if we systematically change the Tier or even the race of a creature, the Hero, or rather their Specialization, will remember it and will work specifically with them.
For example, after Minotaurs became Tier 5, Kifry's Specialization automatically started working with them, and her starting army changed to be similar to other Tier 5 Specializations (Creature Tier 1+2 and one Tier 5 unit). The same happened with the Tier 6 Specialization in the League. After Witches were moved to Tier 3, the Specialization still remembered them and worked with them. However, since Erin is not a "standard" Specialization for creatures, her army became like that of ordinary heroes (although it was like that anyway) - the Goblin Specialization can be included here. Its Specialization is formally Tier 1, but it starts with a regular army.
*The starting army itself is defined in the "RPG file," so I don't see the point in discussing it further.

As a result, what does this give?
By systematically rearranging creatures by Tier and Faction, it is possible to indirectly transfer creature specializations, adapting them to another creature.
For example, systematically swapping Goblins and Faeries and giving Kegan or Dirael a Specialization, making them a non-standard Specialization for Faeries. (they will receive a weekly reinforcement of Faeries or Greydrakes, if available).
The "Wyvern Tamer" Specialization can also be transferred and adapted to another creature, and the bonuses from it can also be edited in the "RPG file," as it is defined there.
*Of course, I'm not talking about the simple rearrangement of "standard Specializations" - it's clear that you can remake Laslo's Specialization, for example, into a Specialization for Monks, giving humans a Tier 5 Specialization.

Correct me if I'm wrong. Let's take Necropolis as an example; it has two specializations for creatures. I can only create a specialization for, say, Liches, by overwriting one of the existing ones, and it's impossible to add it as a third creature specialization, right?

Are these conclusions definitely verified?

Because when I was testing and adding a third tier of creatures, I thought that the creature specialization was hardcoded to specific creature IDs.
But when I started adding them, it turned out that the specialization also works for new creatures, if they are creatures belonging to the same Faction and the same Tier.
For example, Razaz buffs Golden Golems with his bonuses; these are new IDs, but they belong to the Academy and are also Tier 3.

I hope this works for you, but I was disappointed with this method after a mod that shifted Griffins to Tier 6; then, in one scenario, I had to fight 40 Griffins, not level 4, but level 6. The mod went to the trash.
