Sorry to double post, but the problem is that while Constantine has concrete weaknesses (aka the ability to only affect sight), Aura doesn't. True, she's as squishy as a normal human, but that doesn't help when 1.) no one knows of her, meaning that she can get the first hit in, and 2.) when she gets the first hit in, it's instant win. No one, I mean no one, in this RP except [i]the Big Bad[/i] is a telepath strong enough to withstand her*. That means that Aperture has been granted an 'I Win' button.

*Except for Bonjangles, and he can't be everywhere at once.
