Yeah it's finnicky. I learned there's some attacks where you can buffer it by just holding down dodge instead. I think it works after both her ults and maybe the final hit of her EX Special combo, the one with wings? So you just hold dodge during those animations and she'll go right into it.

Also it has a normal version you can activate without the orb which is basically not worth using but I kept doing on accident which confused me. The orb just makes it do more damage, gives it a finisher at the end, and adds adrenaline regen which is the main thing you want.
