Could there be something wrong with the spell Mind Storm?

A Familiar pack just killed my whole party with a cast of Mind Storm. My party has about 11 million defense and no other spell has ever done that, so it’s definitely strange.

Actually, another Familiar pack just beat me with normal attacks, so it must be some of their traits.

I believe it’s the Mystical Familiar. Some boss battles also bypass my Defense for some reason (maybe because of their extremely high levels though).

Judge Familiar has defense bypass trait…

Oh, that’s right, how stupid of me :-X
