Hello everyone i need some help....

[Apaulcalypse]

I've tried to google this and maybe I'm just not typing it in correctly but my question is I have my main archer class that I want to become a bard now I know I have to level a pugilist to 15 but is that level going to grant me all the abilities from that class over to my bard? Or in order to get the full benefit of this cross class system would I have to level the pugilist to 50 to obtain all the moves that cross over or is level 15 going to give me all the abilities? Same for dragoon what level do I have to make my dragoon in order to get ALL abilities from him for my bard do I only level him to 15 or would I have to hit level 50? thanks for the help!
