Demon invasion.

After completing the first half of the first mission and collecting absolutely everything I could, I had a negative stat - 0-0-1-1. The next level was empty, and then it started to increase; I didn't add anything myself. But there, you can play in waves, in a chain, and the spells of darkness return when you learn the skill, plus the starting mana of 250-300 helps you get through the first battles.

Yes, that's true, but I wasn't leveling up after 5-6 levels, so I had to edit the stats. I was already thinking of restarting, but for testing purposes, I sacrificed the purchased Orson at the altar, and after leveling up, my magic skill increased, and it offered me "Artful Darkness." On Berserk difficulty, I managed to break through the guard of the magic skill upgrade and then things went normally:

In general, I won against the Dwarves in about 4.5 months, and the whole mission took 6.5 months, which is an improvement of about a month compared to my previous result. In reality, you can win much faster if you use the previously described bug - make Wolfsten capture the demon castle, and he will die when it is destroyed (a side effect of the RazeTown ability). But I played fairly. However, after clearing the map without any losses (including Hangwul - ), with an army of 4 caravans, I defeated Wolf in one go without giving him much of a chance - . I hope that now I can definitely get the Thunderlord and finally finish this campaign, especially since I did very poorly in the second one last time; there's a lot of room for improvement...

P.s. I found an old, non-campaign version of the first map, where stats are reduced by 1 when transferred. Here, they are also reduced the next day, which is probably why they go into a hard negative
