/*

Spell 2 (Patchouli):

Remilia summons 5 books (5 elements) (see Philosopher's Stone). These books move to the top of the screen and fire downwards lines that restrict horizontal movement.
Remilia constantly will charge down at the player's horizontal position, leaving behind red rings. The player must weave through the lines of the books.
After 3 charges, the books turn into bats that aim for the player, leaving trails of bullets in their wake. Remilia re-calls 5 books and then the pattern restarts.

Note: Books = Enemies with no registered intersection

Parameters:

- Line density
- Line speed
- Line delay

- Ring density
- Ring speed
- Delays between rings
- Remilia charge time
- Remilia charge delay

- Aim speed
