Absolute Radiance Help

I've been practicing her on attuned to try on ascended (beat P5 already) and couldn't beat her today. I got to the last phase but got destroyed (I tried pogoing and leading the orbs off-screen but I kept getting hit anyway).

I just can't seem to figure it out, so I would really like help with it, since I don't have faith in myself to do it on radiant anymore
