Bone Dust World Method

Bone Dust World Method behaves in the same way as Iron Sand World Method. This technique uses Bone Dust to create a gigantic sphere of branching spikes. The user first creates two masses of Bone Dust of opposing magnetic fields (through the use of the Shikotsumyaku's Ferrokinesis) and then merges them together. This causes the magnetic forces to instantly increase and the repellent force created by the two opposing magnetic fields scatters the Bone Dust across a vast area.

The Bone Dust spreads in spikes that branch off irregularly, making it almost impossible to get a clear overview of what is happening. This also makes evading the spikes nearly impossible. Even if the opponent has managed to evade getting hit, the Bone Dust spikes will have filled the entire surroundings, cutting off any escape routes. With the opponent trapped, the user is free to attack in person.

A bonus effect of Bone Dust World Method is that only 50% of the Bone Dust used branches out in spikes. The other 50% becomes free-floating Bone Dust particles which could be deadly if inhaled. If cut with any of the Bone Dust spikes, Bone Dust enters the enemy's body which could allow the user to literally turn their enemy into their puppet due to the Bone Dust and the ferrokinetic powers of the user.
