neither Serie nor Frieren can cast Aura's spell.
Frieren can't cast Diagoldze, just reverse the effects. My pet theory is that Serie analyzed the spell and knows how it works.
Pet theory number 2: Serie will be attacked by curse magic, and she hasn't the curse reversal spell anymore (gave it to Denken).
