I need help again.

1) How do I create a custom specialty for a hero? I went into the shared folder, changed one hero's specialty to another, but when I configure the hero, the specialty remains unchanged. What am I doing wrong?

2) I changed the animation of a creature so that it lies dead. It lies there, but when I test the map with it, you can still interact with it. How can I prevent this?

3) Also, if anyone remembers, in the campaign for Zehir in the original game, you need to kill with several heroes of the same type. How can I implement this in the editor?
