Awakening of Evil

It's possible, but I realized that later, after carefully playing through the game. At first, it was quite scary; the hundreds of mummies near the refugee camp are a good example. And isn't Sigrif supposed to lose levels in the second map of the Campaigns? He remained at level 36, with all his spells and stats intact. They promised something different in the briefing... P.S. The dragon summoning ability was almost useless and often even hindered me. It doesn't work very well. It would have been much better if it was given at the start, as a random bonus, like Lethos's plague. That would have been much more beneficial.

Here's a question: Sigrif did lose a level, which is fine. All stats except for 1 Knowledge and 1 Sorcery were reduced to zero. Is that normal (what the heck, why to zero?!?), but when I approach, say, a planetarium or a crystal of revelation and interact with it, it says that everything is fine, that everything has increased by one, but no, nothing has increased. I've already visited 3 planetariums, but Sorcery is still at 1. Is this some kind of feature of the map? And if so, what is it? Leveling up also doesn't add anything to the characteristics... I have a bad feeling that after the stat reset, I somehow ended up with a net loss... 5 planetariums gave me a bonus of 1 Sorcery. There's a lot to think about... I'm worried about the fate of the dark elf race... Who is to blame, and what should I do?
