Scripts

His level is definitely 20th, I gave him experience and abilities in the editor, and it's even written on him.

Here lies the problem. The trigger for increasing the level only works if the level increases during the game itself; if it was set in the editor, it won't happen. Therefore, only this line is triggered:

SetGameVar("LevR", 1)

, which is why the combat script always thinks the hero is at level 1.
