Posts from RTF is a global modification that replaces all towns in the game.

UPD: https://ibb.co/YBWMQW1 https://ibb.co/4s5qbr9 https://ibb.co/wdM72DZ there are a couple of minor glitches like these, I'm not implying anything, but... I'd be glad if you could fix them ＾◡＾

By the way, do you know where the hero specializations are located? I wanted to change Vlad's specialization to one of the heroes from the NHF mod.

There's an issue with this – all new heroes in NHF come without specializations, and new features are created using scripts.

Nephilim look really cool! I personally like these "warriors of death," faceless, in a black cloak. Upgrades, I assume, will get a couple of colored details, blue/pink, like the undead?

I uploaded the icons, fixed the Ifrit faction, rewrote the description for the Gargoyle dwelling, and added an individual model for one of the elementals.
If you need to rewrite other text files, you can find them in the \Text\Game folder; everything is organized into separate folders – cities, heroes, creatures, etc.

P.S. I felt scared for the first time in a long time – I couldn't immediately figure out this mod... instead of reworking the creatures' stats, the paths to the creatures' stats have been reworked, which turned everything into a mess; I just don't understand...

Thank you for your help; I'm a beginner when it comes to modding, so there are some mistakes. Everything I found on this topic was Sashager's video on replacing a unit and its stats.

The only mistake I found was with the Ifrit faction – you added upgrades and characteristics, but you didn't define the faction itself, and there was a complete mess in the mod initially. I cleaned up this nightmare a long time ago to be able to properly modify the elementals, and then I switched to RTF and deleted it because it was no longer needed.

By the way, troglodytes could be made into an underground faction; they would be perfect for this role. And as a racial ability, you could simply rework the demon gates, as if additional troops are breaking through tunnels on the battlefield.
