Any tips for Sister Friede’s final phase?

I’m looking for some advice with Sister Friede on NG+, and specifically her third phase.

This is the first time I’m fighting her on NG+, and this time I’d like to not summon Gael and beat her solo.

I’ve been able to get through the first two phases, but when she switches to Blackflame Friede in her third phase, I really struggle to dodge her attacks.

I’m sure there’s a pattern to it, but it just seems like a mess of swirling black flame and frost attacks that wipe me out.

My build is an SL120 pure dex build, using the sharp Astora Greatsword (+10), so I know I’m well equipped. I’ve also got the Sellsword Twinblades in reserve, but I’d rather than use that cheat code of a weapon if I can avoid it.

Does anyone here have any advice or suggested tactics?
