Heroes with the required skill.

I believe it’s necessary to continue our discussion in a private message, where I will later explain my thoughts on what you consider to be a “simple” issue. For everyone to see, I will say that after such a long time since the game’s initial release, there simply cannot be any “simple” things left in Heroes 3, as you should be aware of how much has already been written and rewritten on this topic over that time. Therefore, even if your work is somewhat similar to something that already exists, it should at least be made beautiful and carefully considered multiple times. Sincerely.
