Earth Release: Migrating Barrier

He first tosses his staff into the air, quickly forming the snake seal before slamming his palm into the ground; using his chakra to manipulate the prexisting earth he forms an earthen wall of variable size; the wall itself is strengthened by his own earth chakra, making it all the harder to damage. He then strikes the wall with his staff, using his earth chakra to effectively shove the wall in the desired direction; the barrier moves quickly and yet maintains it's structural strength, acting as both a barrier and a battering ram for combat.
