I would like to know, if possible, how a multiclass character non weapon proficiency works after level 1. In the players handbook its not clear at all. It just states:
If the optional proficiency system is used, the character starts with the largest number of proficiency slots of the different classes. Thereafter, he gains new proficiency slots at the fastest of the given rates. To determine the character's initial money, roll according to the most generous of the character's different classes.
I would appreciate if anyone here could tell me if there is some kind of official answer from the game producers or something that could be considered "official".
It would be best if you could post a link from the page containing the answer that I'm looking for.
