idk the specifics but when I was a (bigger) noob she hard carried as a 4* until act 5
You can just not take any damage the entire fight
Big part of her utility is that when awakened, she completely ignores damage when phasing - which means you can ignore a lot of punishing mechanics by activating phase at the right time. Also very good uptime on incinerate and can ramp to some pretty big specials.
Recklessly dashing into Serpent's specials is gonna be a fun time.
Legitimately would work if she’s awakened - you’d take no damage and build a bunch of power.
and gaining all that power from getting hit straight to sp3
