Study 15 archtypes

[Zorant]

Ok does this mean I have to unlock Every archtype in the game on my mc or get all the basic ones to level 20 and unlock advanced ones on the mc? Or is it unlock 15 different ones across all character? If its the last option then is it time locked (meaning I can't do it until later in the story?) because I have 15 archtypes studied over the now 4 characters I am playing with.

any 15 unique archtypes across all your characters.

seeker+merchant=2

merchant+merchant=just 1

you might need to make more friends/level up your social link to get enough, if you have been slacking
