Wdym broken? He's c0r0

She already does everything DMC do in non burning teams without ER reqs and very minor buffs. There's no comparison for teams with burning present.

make sure to level her to 90 if you plan on using reactions! that’s what helped her a lot for me I think it’s a whopping like 20-25% reaction damage increase
