The Spin

The Spin is the ability system of Rokenxia campaigns, heavily inspired by the natural phenomenon in JoJo's Bizzare Adventure of the same name, in that objects that are spun to achieve the Golden Ratio, a nearly perfect rotation that produces more energy than it takes to create. This energy can then be applied for a multitude of purposes. Modifications can be applied to weapons to ultilize this energy, and devices can be made to truly harness it.

## Lore

While always being present in the world, the Spin was discovered to be utilized during the exploration of the Floating Isles of Grizo. After this discovery, it became a staple of the Kingdom of Grizo, becoming used in daily life as the number of applications of it increased exponentially. The discovery spawned the Spin Discovery Calendar. However, Valus Perdere, the first masterer of the Spin, discovered it 22 years prior to its universally accepted discovery.

## Spin Cells

The Spin has a unique effect on objects. When an object is spun to achieve the Golden Ratio to create Spin energy, or when Spin energy is created around the object, that Spin energy will take on the properties of the object. This energy can then be channeled and released for a variety of uses. However, the full extent of the created energy cannot be harnessed unless the object and its Spin energy become a Spin cell. After a period of time at which Spin energy is being created from or around an object, the object itself will gradually become Spin energy, creating a Spin cell. This is where the power of the Spin energy is at its fullest extent. So long as the Spin cell is contained, it can be applied for a number of purposes.

## Applications

#### **General Utilization**

The Spin at its core is simple, spinning an object to a near-perfect rotation produces energy which can be used for mundane purposes, such as throwing an object, performing a simple trick, adding power to a punch, performing an action more acrobatically, turning trees to clear a path, etc.

#### **Weapon Modification**

Weapons can be modified to utilize Spin energy, such as arrows being modified to spin to the Golden Ratio as they are fired, swords being modified to release Spin energy as they impact a target, thrown weapons being modifed to return to their user, etc.

#### **Devices**

When an object is spun to the Golden Ratio, the energy created takes on the properties of that object, as the object also becomes rotational energy in itself. When that energy is released, it mimics magical abilities. Devices can be created for this function, and they all work similarly. An object is spun in the center of one of these devices, and because of the regenerative properties of Spin energy, perishable objects, such as ice or a small flame, last as long as the spin lasts, but eventually that object will become a Spin cell. More energy is created from the object's spin, and it can be released from the device in a large variety of methods, diversifying abilities.

#### **Machinery**

Because of the seemingly infinite amount of time an object can be spun to create Spin energy, their application to machinery is extraordinarily useful. This makes them very desirable by people looking to cut costs.

## Mechanics

#### **The Basics**

While Spin energy is measured by the GM based on the players coming up with utilizations, a few basics remain.

Tiny Spin cell = 1d4 - 1 ability

Small Spin cell = 1d6 - 2 abilities

Medium Spin cell = 1d8 - 3 abilities

Large Spin cell = 1d10 - 4 abilities

One foot of the circumference of Spin energy is equal to a large Spin cell.
