Sorry for getting to this late, gotten behind a little bit.

If you haven't already beaten it, a few tips:

The overhead tentacles have pretty small hitboxes and you can avoid them just by taking a step forward or backwards, but often rolling is easier. If you destroy them they will respawn indefinitely, but often I just ignore trying to damage them. Just focus on targeting the eye and you should move her into phase 2 within 30 seconds.

When she attacks 8 tentacles at once, single EMP grenade and you're good. She'll enrage so just get the shield out. Rinse and repeat 3x and you'll be in the final phase in about 3 minutes.

Final phase, use the defender (green shield) you'll figure out what to do pretty quick. :)

Sorry. That's actually fixed in the next patch. Well, mostly. The first half is skipped so she has 3 lines and then fight. It was the cleanest way to do it. Putting that patch up in about an hour.

I think quickly though is my problem lol. Fixing one problem and adding another every time. :)
