I appreciate the though, but frozen blood isn't very good. It has an odd consistency
So, Yuna, did you see what I can do? I can turn into pure darkness!
*black mist starts emanating from body, body turns shadowy, eyes start glowing*
*becomes solid again*
I can't maintain it for more than a few minutes...its like being intangible, only you still have a visible form. Really hard to do it. Dissolving into darkness and teleporting somewhere else is much easier. And fun!
