Sky Crawler

A relatively difficult technique where the user expels and solidifies chakra at the bottom of her foot or feet, creating an anchored foothold that allows one to travel on any sort of terrain as if it was ground hard enough to be perfect for your feet, even if that terrain happens to be the sky.

The main draw of this technique is that the user can draw the chakra used for the technique back into the body when the user doesn't need the platform anymore, making the only chakra cost of this technique only what is needed to move the chakra and solidify it. It is actually cheaper than even tree walking.

The user can expand the platform to accommodate more people if needed, and even choose to leave the platform without drawing the chakra back into the body so as to aid allied reinforcements in their travels. Doing so, of course, increases chakra costs.
