I have noticed that quite a few systems have characters that focus on three different pillars in the form of physical strength, charisma and booksmarts(Storyteller System, Some PbtA systems,) and I observed this when it came to D&D esque systems where there is a character that does the talking, there is a character that knows all the lore(Usually the wizard) and there is a character that is all about hitting things hard.
I know that the characters that do the talking are usually called the face but is there a term for the characters that specialize in rolling knowledge and characters that specialize in physical force?
