[quote]but it also becomes a bit more blurry, by which I mean that her body becomes a bit less physical in order to allow her to try and use the full potential of her powers.[/quote]
This. Please delete this and make her body 100% physical. She's a Fae, not a Spirit so her body should be 100% physical. 

[quote]Her body also becomes a bit less physical, and while it is not impossible to hit her with physical attacks, doing so might make the opponent who attacked her suddenly feel static or become a bit paralyzed for a bit, due to the lightning going around her body.[/quote] Same wit this body. While she could (potentially) surround herself in a small dome of static electricity, she is still 100% there and if someone hits her she will be hit.

[quote]This ability also leaves her feeling rather exausted and she will need to recover for a while. There is a large chance that after using this she will go out of her Shifter form[/quote] And another bit I'd like deleted :) While her most powerful attacks will drain her a bit, it won't exhaust her nor force her to exit her Shifter form (in fact, you can only exit the Shifter form by doing it yourself--willingly.

Last thing: I'd like a reason for why she doesn't like flying. I believe that most people would jump at the chance to fly under their own power, so why doesn't she like it?
