Except that wasn't the context. Luke referred to it as "...your fire attack" on page 21. On page 31, the Knight referred to Noel's powers as "...her tremendous fire magic". Which is why I commented what I did, because every time Noel called out her attack spells, she specified they were wind magics.
Either the author or MF messed up. Given track record, I wouldn't be surprised if it was MF.
