The Guardian Angel will be enhanced in the future.
I've already changed the skill tree about 10 times – I can't seem to finalize what and where it should be :D. The version on the first page is very old; I'll post a newer version later. For now, here's the calculation for some Chaos spells. I liked Nargott's idea of differentiating the principles of magic calculation by element, and I've done just that:

Excellent option. I suggest we stick with it. Colleagues, we need to start with something, otherwise we'll be discussing it for another year. Questions:
1) Why specifically the Guardian Angel?
2) What is the latest, most up-to-date version of the skill tree for Humans, Necromancers, and others?
3) How much can Nargott's calculation idea affect the balance? It's important not to overdo it, as otherwise we could ruin the whole game.
4) Are there any plans to add new skills, abilities, or specializations to the skill tree?
5) What do you think about the idea of increasing the number of skills from 3 to 4? That is, there will be 24 instead of 18. Perhaps, in this case, it will be necessary to add new skills to the game. If necessary, we can increase the maximum Hero level to 42 or 45 (this is just my suggestion).
6) Question for Nargott. Tell me, what do you envision as the final version of the skill tree?

Colleagues, I look forward to your answers and comments.
