Last night there was some boss optimizing going on in distortions stream so I decided to make some attempts myself.

It seems like you can clip into her hit box and one swing connects multiple times.

The execution is semi-consistent but it allows you to take her out in 2 swings (ignore the 3rd swing as she was already in her death animation).

Just wanted to share this in case there are other bosses with exploitable hitboxes for faster kills.

Here is my clip, I'm new to streaming so let me know if I didn't link this correctly:
