Demon invasion.

I started a hardcore Campaign on a hero. I spent 2 months running around my territory, clearing everything except for the Titans near the library and opening a one-way portal. By that time, the demon gathering had been reduced to just one Alastor, who, upon seeing me, immediately teleported back to his Castle . I ran around almost the entire map looking for upgrades and attacked him in his Castle. After the victory, there was a cutscene, and I was moved to the next level. At the same time, all skills were taken away, attack and defense were reset to zero, and magic and knowledge were reduced to one. I was a little surprised, but I thought that's how it should be. Fortunately, the first and second-level spells were preserved, and I had a mana reserve of 300. I attacked two hundred bears with 18 Imps and slowly and tediously spat fire at them, dealing 35 damage . After the battle, I was given level 5, and I learned new skills, but the stats remained at zero! This is clearly an exaggeration. The save file is 8 MB - unfortunately, I can't upload it.
