@Cleopatra@Ariamis In my opinion, if you really cant think of anything (because I dont see telekinesis fitting, nor gravity magic), it might be best just to re-do the wish entirely.
Shapeshifting would work, but apart from that I cant see anything else that does. Unless you were able to come up with better secondary abilities.
If that is the case, might I suggest a few ideas.
1)
Adaptive Combat: Reflecting a constant change in nature, couldn't it also work for her entirety as well? If so, then having her very fighting style alter depending on the situation would be interesting.
2)
Animal Adaptability: Perhaps altering her body in slight ways, like gaining things of other creatures? Bat's echolocation, dog's sense of smell, etcetera. (I know you already have this, to a degree, but not to this extent).
3)
Illusions: Similar to Kyoko, her magic could similarly be interpreted as an illusion. I mean, she is constantly changing, so why not make everyones perception of change enhanced?
Make them think everything has changed, and
make them see that change.
4)
The Study of Change: Why not change the things around her? Maybe break down molecules, change atomic structure? I mean, she has the potential for it, because that is a mighty fine 7, so why not utilise it?
Of course, this could all be nonsense with me rambling, but eh. I have nothing better to do.
