Is this mod compatible with mods that change the balance, such as the UNIT mod?
Wonderful... if there are insurmountable problems with some heroes, then we will ask the respected comrade Dyrman to work his magic...
No, there will be no problems. Some heroes will even be improved, for example, those using special abilities (Valafar, Biara, etc.).
By the way, regarding what I wrote earlier, about heroes like Hafad. It will not be possible to completely get rid of the triggers affecting heroes, because some special abilities in NHF will not work without them at all. Therefore, the idea is that such special abilities should trigger BEFORE the battle if the battle is with a hero, and if the battle is with neutrals, then already at the beginning of the battle in tactical mode. This way, the special ability will work in all possible cases (including those that cannot be intercepted by triggers - for example, against creatures generated by the creature generator, guardians in treasure rooms, etc.), and in battles against heroes, there will be no need to create various workarounds. Just add a condition that against heroes, it will trigger before the battle, and against neutrals, it will trigger during the battle
