Thus, they can maintain objects in place like a cape to function like a sail or unravel objects like a tree's bark.
It allowed Gyro to becomes bulletproof and withstand the blast of one of Boku no Rhythm wo Kiitekure's bombs and only harm his leg or Wekapipo to redirect the energy of a Steel Ball. The Spin can affect the body to harden it and enable it to easily transmit energy somewhere else, granting supernatural but temporary sturdiness.Wekapipo's satellites are also propelled with as much force as bullets, being able to tear Gyro's hand. A Steel Ball imbued with the Spin can destroy great chunks of rocks. The Spin naturally enhances the destructive power of a projectile and thus can be thrown to simply inflict damage.Others like the members of Naples' royal guard only use a highly specialized application of the Spin on the human body. For instance the Zeppeli Family are trained as surgeons to use the Spin on criminals on death row, otherwise, the Spin may only result in a simple enhancement of destructive energy. One must also know the human body extremely well to exploit the effects of the Spin on people to the fullest. Thus, a Spin user must be able to expertly aim and throw objects in order to hope for a result. The Spin must be imbued into a medium that will keep on spinning and must be thrown so the object can transfer the energy through contact. The Spin is deceptively and relatively easy to learn at the basic, as the novice Johnny Joestar manages to produce a conclusive Spin with a cork within a day of learning about the power's existence however, it is extremely difficult to master.
One advice given to neophytes is to visualize the perfect rotation and then trying to emulate it.
To do so, they apply a small force causing the object to Spin near perfectly, giving it an impulse of energy to start the rotation, and then let the rotation perpetuate itself. Users of the Spin typically try to spin objects to follow as best they can the Golden Rectangle, creating a near endless rotation that may then create an infinite amount of rotational energy, before throwing said objects at a target. All characters capable of performing advanced Spin techniques are either Neapolitan or have been taught by a Neapolitan. It is intensively used there either for medicine or for battle. The Spin is a specialty of the Kingdom of Naples. That rotational energy is transferred to nearby objects in the form of vibrations and can be wielded for a wide array of purposes. Unlike the average rotation, the Spin is persistent and produces more rotational energy than it takes to create.
