Oh my bad on the soul merge. I forgot about that part.

In FbG, there are four layers of reality. From lowest to highest, Physical is Assiah. Mental is Yetzirah. Spiritual is Beriah. Conceptual is Atziluth.

Being able to manipulate a higher level of layer gives you the ability to manipulate things on a lower layer, bypassing lower layer resistances. Control the mind, control the body. Control the soul, control the mind. Control the concept, control everything about them.

In other words, if she doesn't resist soul hax, that possession (which is 3rd layer - soul - magic) is going to straight up ignore the mind resistance.
