You need to make sense of "Assist Defence" for yourself
Make sure that you have 5 gluttony
Have Mao Faust use either skill 3 or power counter
Have one attack from the enemy be unclashed, AND the target should not be using defensive skills: be it Guard, Power Guard, Evade, Counter or Power Counter

Whenever a Deathrite is proc'd by someone else, Faust gains 1 star.
Whenever a Deathrite is proc'd by Faust herself, Faust gains 2 stars
Whenever Assist Defence procs and she clashes, she gains 5 stars
When she has 10 stars, the Assist Defence morphs into skill 3-2
I can't understand it for you, it is best you take her to the Railway and learn through experience

He really REALLY should have stuck with his guns and nerfed Mao Faust
