DFFOO GL - Dare To Defy: Battle's End - Nyx III (Beatrix Solo)

Sorry, it's another straightforward counter solo. It's the last for the Nyx series though.
I want to use all of the FFIX characters in my runs for this, and that starts here with Beatrix.
...On the bright side, this is the last time I have to say anything nice about Beatrix. ;P

My Beatrix keeps getting paralyzed. Also at some point, they stop taking damage. Also they keep getting to Force Time before I do. My unit is maxed out and I'm following everything that you did in the video. Is there something I can do?

I'm using Crystsl passives. U5 Crystal passive gives you debuff immunity for the whole fight. D3 and D6 passives give the enemies more turns, I also removed her speed passives.
They get huge damage mitigations when the Force Gauge fills up, so you need to charge yours before them. If Beatrix is slow enough, this should be doable at FE50.
