A program for determining luck/morality in Heroes 3!

Why did the numbering suddenly start from one in the comments?

I smiled, thank you :)

Please explain what this "beast" is - the tree number?

This is my name for it (it's more convenient). It's used to obtain the Seed, in simpler terms.

Seed = 343FDh * Hero_Level + 26497h * N + 259DFh

Yes, and a logical question: does visiting objects, as we used to say, that "reset" the skill tree, leave R unchanged?

Yes, a new skill is simply added. Accordingly, the sum SUM_W changes, and other skills are generated (i.e., the tree is broken). The algorithm works in this case as well.
