Iron Sand Wall

Wall of Iron Sand is a defensive application of iron sand control. The user gathers a large amount of sand and compacts it, forming a solid barrier in front of themselves. Such a wall is comparable in hardness to steel and is capable of withstanding powerful attacks, including penetrating projectiles like Gosunkugi. The shape of the wall can be changed at will: it can be flat, curved, or envelop the user from several sides. The magnetic field created by the sand additionally deflects metal weapons. The technique requires a significant volume of sand and precise control, but does not inflict damage on its own, though it can instantly reconfigure into a deadly weapon.
