[8%]: "Luke must have anticipated that I'd use a wind spell to blow his spell back." The word "spell" is repeated. Perhaps "a wind spell" could be replaced with "wind magic" or "a wind incantation?
[16%]: "(...) and unleashed the spell I'd chanted as I pulled him toward me." What spell? There is no mention of any spell effect after this in the narration, Lina simply describes Luke jumping at them. Is there a missing sentence or two here?
