Description: By performing the Tiger hand seal the user then makes a gigantic rampart rise up beneath the user's feet, by shaping the ground and increasing the amount of earth with chakra. Depending on what the user imagines, the shape of the rampart can be anything from level ground to a steep, needle-like mountain. If the user increases the volume of earth too much, he can be forced to keep his chakra consumption down. The user can combine this jutsu with Water Style: Waterfall Basin Technique to create a waterfall.

Make the tiger handseal and then you can raise a giant plateau looking earth rampart under your feet to rise you upwards in the air. The size of it depends solely on you.
