- You will get the Railway Spiral as a new design.
- The main effect of this spiral is about Attack Speed and Spiral Equation.
- Active : You will gain Attack Speed as a Passive effect based on the duration for which the Spiral Equation is equipped. The more Spiral Equations you have equipped, the greater the effect.
- Passive : Equation Slot +2

Additionally, purchasing this DLC will unlock the Train Mode. By clicking the ladder-shaped icon in the bottom right corner,
you will enter Train Mode, which changes the perspective to make it seem like you are at the tip of the spiral.
You can freely change the viewpoint by using the arrow keys.
This will enable you to create even more beautiful spirals!
