From Frodo's perspective?
I think it is fair to at least mention the fact that, unlike other hobbits, it is explicitly mentioned that he was extremely curious and liked to discover new things.
Moreover, given the nature of their village, he had no idea of the horrors and dangers of the outside world.

But just if we find such a commoner in Baldur's Gate 3, I see no reason not to take him with us. laugh

I liked original spellcasting system more ... frown

Anyway ... i cast Eldritch Blast!
