Weaponized autism
She's an Archmage who has spec'd her stats and skills entirely into Explosion magic and nothing else, and she's from a tribe of autistic mages who were literally genetically engineered for peak magical performance.
Since her Explosion magic is by far the strongest weapon her party has, she's also killed most of the bosses they've come across, which means she's soaked up a ton of EXP and gotten overleveled which has made her even stronger. Even though she's an Archmage and a delicate young girl, she has more STR levels than her boyfriend.
