/*

Remi Spell 1

Remi moves to your current position (takes 36 frames), fires a dense star of stars (lol) that fades away quickly, and waits a set number of frames before repeating. After 3 waves of this, she moves to the middle and shoots a thick spiral of fireballs that requires you to spin around the screen for a bit.
She also leaves behind trails of rings with every dash.

Remilia takes 36 frames to move to you each time. -> delay between rings: 9, 6, 5

Parameters:

- Remilia wait time
- Spiral density
- Spiral speed
- Spiral angle offset per frame

- Ring density
- Ring speed
- Delays between rings
