Skull of Shadows (SoS) is a Polish mod that replaces all the factions.

in that case, I'll give it a try.
as I understand it, everything is divided into two stages: find suitable models and balance them.
I don't know how to balance (in terms of abilities), but I can adjust the skills (or suggest them for certain creatures).

So, NOIADE will balance it semi-automatically, i.e., a person needs to "feed" it with an .xdb file, and it will balance it itself... at the same time, it does not change abilities, special abilities, or spells... spells and the amount of mana need to be adjusted manually... but there are not so many spellcasting creatures in the NCF project! That is, the particularly overpowered ones should automatically move to level 8... at least, during selective testing, the functionality worked exactly like that, but if it complains about someone being too overpowered, you need to send it to my email, and I will forward it to the author of NOIADE so that, as they say, he can fix the functionality on a real-world example!
