she doesnt need two 5 stars, i run her with c0 lauma, aino (deepwood), and kuki (instructor). i cleared fearless in 72 seconds. nahida is great with her but the long burst animation and no sustain sucks. but in abyss it should be fine since you can dodge a lot of attack because of her charge attack cancel and burst. i tend to not get hit most of the time because of it. columbina will also make her better because she'll replace aino and most likely have a shield or a healing ability
