You know how to use the Spin, able to follow the Golden Rectangle to use a simple object like a marble or corkscrew as a potent projectile or to harden your body to the extent of making you bulletproof. Eventually, you may unlock a Stand through mastering the Spin, and if you're lucky, you may get a Stand that would allow you to bypass Scion's dimensional barrier, however the rest of his defenses are a concern you'd need other powers to work around (Even with Sting, you wouldn't be putting out enough damage to kill Scion in a reasonable time frame) and while it is deceptively easy to learn the basics of the Spin, it is extremely difficult to master.
Fibonacci Configuration
Having learned the secret of the Golden Ratio, you subconsciously arrange your 108 skill slots into a shape which follows the Golden Rectangle within your soul. As a result, you may channel the Spin through any of your 108 skills, allowing you to impart rotational energy through anything you do with them. As your mastery of the Spin grows, so too does the power of this rotation.
