What it says on the tin.

The dialogues failed to tell me what to do in order to stop her from regenerating.

I oneshot her first healthbar, she now turns into a golden orb that levitates over her "corpse" and I get told to stop her. What should I do?

My amp wont do anything, "Voidslinging" wont do anything, I cant do any more void pulses with E since it just swaps me back to my frame.

What am I supposed to do?

Thanks in advance.

Edit: I have beaten it and finished the quest. Thanks for the help I will keep those post in case others need help.
