Hero creation utility.

That's why it's always important to clearly explain what you're talking about! Especially since I see you're not new to "Heroes"; it's time to learn the terminology.
After reading your description, I'm almost certain that you're talking about this program:

AboutHeroes3
If you need to quickly recall information about any hero from Heroes III, use the AboutHeroes3 utility (author - Alex L). You will learn not only all the initial data (specialization, initial skills and parameters), but also the development prospects of the selected hero in the form of tables showing the probability of obtaining primary and secondary skills.

But, if this is it, then it doesn't create a hero, but only shows information about him!
