Iron Sand Rain is a long-range attack that is part of the arsenal of the Magnetism Element. The user grinds iron sand down to the state of the finest granules and fires them simultaneously over a wide area. The projectiles are accelerated by the magnetic force of repulsion, so they fly so fast that they are practically impossible to make out. By the time the preparation is complete, dodging becomes extremely difficult. The shape of the granules can be changed: instead of spherical bullets, the user is able to create sharp needles, increasing the likelihood of a lethal hit. Since the iron sand is magnetized, and in Sassori's use is also soaked in poison, defense against this technique is extremely difficult. It poses a particular threat to puppeteers: upon getting into the joints of marionettes, the sand jams them and deprives them of mobility.
