I'm wanting to mix archetypes (traditions) for my monk. I'm wanting specifically the 3rd and 17th level feats from Way of the Open Fist and the 6th and 11th level feats from the Way of the Shadows. I know we can't multiclass into the same class to gain both but in the PHB page 79 2nd column "Monastic Traditions" reads "Three traditions of monastic pursuit are in common in the monasteries scattered across the multiverse." I'm fine with that but where I question is "Most monasteries practice one tradition exclusively, but a few honor the three traditions and instruct each monk according to his or her aptitude and interest."
So my question would be can I build a monk that is split like that without homebrewing to much?
