I know very well that MV allows you to consume an item and automatically teach the target hero some skill. That's what has inspired me to look for a way to limit that ability to only allow certain actors or classes learn such an useful skill.
Leave a Note in the Item's Note Box for specific Actors: _teach skill actors 1_ _teach skill actors 20 45_
Leave a Note in the Item's Note Box for specific Classes: _teach skill classes 1_
_teach skill classes 4 17_
Obviously, you can add as many actors or classes as deemed necessary.
