How does Learn a Spell work with repertoires? For example, my primal sorcerer obtained spell scrolls of heal and fear, neither of which were in their repertoire. From my understanding, I roll a DC 15 Nature skill check, spend 2 gp per spell, and 1 hour per level of the spell learned.
What happens next? From what I understand, these new spells would become available as spell choices once the sorcerer went up a level. There's no immediate advantage to adding spells to the repertoire (unlike a wizard's spellbook), but it expands available spell choices as the repertoire caster becomes more powerful.
