[@Lucius Cypher] Quick clarification question, but are the stats and proficiencies our character's or their persona's, or should they match both? So for example, if someone had a physically meek kid with a barbarian persona, would a high STR just mean the Persona they summon is strong, or would the character be surprisingly so as well? Or is it preferable that there wouldn't be a disconnect like that?

That example isn't what I'm going with, but illustrates the point.
