I'm having some trouble fully understanding how this is supposed to work. You're expending Aura for something, but i can't really tell what exactly this aura does, or how much it does.
In the beginning it says "use aura to respond with natural speed" which doesn't really make a lot of sense to me. Then later it says something about matador capes and somehow 'dodging' with electromagnetic aura pulse. For one thing, this description needs to be more concise and less convoluted about what it effectively does. And if it gives any kind of boost to stats like speed to dodge, it needs to be less spongy in it's wording and have a simple formula to how that boost works (i.E.: half of Aura used is Speed bonus until next post; expend X amount of Aura after initial activation to gain Y amount of Speed bonus for duration Z; etc.).
