She doesn't have her powers here

Focusing on adjusting her dress into the form she had seen on the woman in one of the pictures in John’s room Damiana was frustrated to find nothing happen. Trying again by snapping her hands to just add some length to the dress and again nothing happens.

It seems that her powers were tied to the device in her hand and only accessible to her if she travelled to another universe with it. Thanking her luck that at least her body was unchanged and as such still supernaturally beautiful and possessing incredible physical strength, she ponders what to do next.
