Ice Release: Rampart

The user creates a massive wall of ice. This technique drains a large amount of chakra to cast, although the quantity required can be reduced if there is frost present in the air, or a pre-existing source of ice/snow/water.

The thickness of the wall depends on the skill of the caster; a master of Ice Release is capable of making the wall as thick as that of Konohagakure's, however a novice would only be able to make it relatively thin, such as those used in Demonic Ice Crystal Mirrors. Shattering the ice with a physical ice when the wall is at its thickest is near-impossible; in this form it may take up to a week for the ice to melt, or if the climate is cool enough, show signs of decreasing in size.
