Rabi-Ribi - Boss HP Thresholds

Done on v1.75, casual difficulty, and standard mode with Cheat Engine.
	Items weren't documented but may affect boss/attack behavior?
	Assumes bosses operate on HP percentages but this may not always be the case?
	Some of the symbols may be inaccurate (e.g. 15% of 5610 HP is 841.5 so I'm unable to test this exact percentage).
	I didn't test amulets on all these attacks.

=====
	100%-75%

Note that I've only noted the immediate guaranteed attacks but Kotri 2 seems to always perform the same sequence of attacks if the conditions leading to it remain the same.

=====
Kotri 3
=====
	<75%-50%
		Jump back and arrange bits to shoot
		Priority 2
		She can perform this above or below the threshold but as a randomly selected attack. Even if she performs it early, she's still guaranteed to perform it again upon knocking her hp into this range.

		Jumps up and shoots hearts that shoots lasers in four directions.
		Priority 1

Lilith's first attack above 85% is random. However, it seems after this Lilith will perform the same next few attacks if the conditions leading to it remain the same.

=====
Lilith 2
=====
Blue Defense Boost is constantly applied during this fight.
	100%-80%

These ranges may not be accurate. I've only done one trial and went down by 5% increments at a time.

=====
Miru
=====
	30%
		Lucky Seven

	<15%
		Hex Cancel
		Double Damage

=====
Nieve

	<75%-33%
		Either sprays snow around her or runs to the middle of the room and then jumps up to shoot bullets outward.
		The former seems more common if you have items while the latter seems more common at 0% items.
		Priority 1

	<75%
		Jumps away from you and then sends snowflakes that will fall on you. May send a few at a time that spawns bullets upon landing on the ground or a send a constant stream. The latter seems rare or requires additional conditions (maybe she has to perform a certain amount of attacks first?).
		Priority 3

	<43.3%
		Submerges the room in water
		Priority 1

	<33%
		Cut-In
		Priority 2

=====
Nixie

	<33%
		Cut-In

=====
Noah 1
=====
	100%-67%
		Scatters blue and yellow orbs or sends out a green orb that travels to you then splits into small green orbs.

	<90%-77.5%

		Shoots a fountain of blue orbs with Super Armour (Amulet multihits) or sends up lasers that rains down or homes on you.
		Cannot be used as the first attack.
		May be skipped if second attack is of a higher priority move.

	<77.5%-67%
		Sends a yellow orb that chases you or one or three large homing blue orbs that inflicts Speed Down.

	<67%
		Cut-In followed by many attacks from other bosses in a static sequence.
		Will gain Defense Up afterwards and throughout the duration of the Ribbon attack.

	<0.15%
		Red Defense Boost. Start Noah 2.

Noah can probably use her pre Cut-In attacks after 67% but she performs so many attacks after her Cut-In that I didn't look into it.

=====
Noah 2
=====
	Noah 2 always starts with spinning across the platform.
	100%-80%
		Flies across the top of the room while streaming two lines of bullets onto the platform.
		She can still perform this attack below 80%.

	<80%-40%
		Borders move in from the sides of the room, stopping in the center.

		Descends one side of the platform then moves across it leaving behind orbs that expand.
		Priority 2

	<40%

		Priority 1

Note that I've only noted the immediate guaranteed attacks but Noah 2 seems to always perform the same sequence of attacks if the conditions leading to it remain the same.

=====
Noah 3
=====
Doesn't seem to have any HP dependent attacks. Instead she'll perform the following sequence:
	1) Calls down lasers columns in front of her.
	2) Places an orb over you that sends out circle bullets outward in clockwise and counter clockwise motions.
	3) Randomly selects one of the seven attacks:
		Repeats the first attack.
		Repeats the second attack.
		Places an orb over you that expands and becomes a cluster of bullets.
		Generates a cluster of lasers that curves and disperses.
		Sends giant/shrink orbs across the room.
		Jumps back while shooting out many bubbles. If quick reflex is induced, it is retained during this attack.
		Jumps up and shoot lasers that home in on you.
	4) Calls down a single column on you or two columns on the side of the room that dissolves into bullets. Charged shooting the columns will remove a portion of it.
	5) Generates a cluster of lasers that curves and disperses.
	6) Jumps back while shooting out many bubbles. If quick reflex is induced, it is retained during this attack.
	7) Either jumps up in the middle of the room and shoots out waves of bullets that phases in solidity or jumps up and shoot several orbs at you that slowly move towards you and remain on screen for a long time.
	8) Sends giant/shrink orbs across the room.
	9) Sends down fans of straight bullets from the top of the room or moves to one side of the room and constructs helix in the center of the room that will dissolve towards your position.
	10) Jumps up and shoot lasers that home in on you.
	11) Moves to the middle of the room and jumps up to sweep a laser across the room, leaving bullets behind in the sweep.
	12) Calls down lasers columns in front of her.
	13) Jumps up and calls down shooting stars while spiraling orbs outward or moves to the middle of the room and jumps up to send out bullets that spiral in a clockwise or counter clockwise fashion.
	14) Places an orb over you that sends out circle bullets outward in clockwise and counter clockwise motions or places an orb over you that expands and becomes a cluster of bullets.
	15) May ends several orbs to the top of the room that will shoot a constant stream of bullets in several directions or may send out lasers with bullet trails that widely home in on you.

Her sequence probably continues from this point but I didn't documented anything beyond this.

=====

=====
	100%-(>80%)
		Jumps up and shoots tri-shots aimed at you. Can still use after this hp threshold.
		Priority 1

	80%-(30%)
		Jumps up and shoots homing bullets. Can use at and below 30%.

=====
Rita
=====
