Chimera

**Chimera** is a boss added in *The Binding of Isaac: Repentance* that can appear in the Corpse.

## Behavior

### Phase 1

Chimera trots quickly in Isaac's direction, slowly building up speed. When fast enough, it leaves a trail of harmful Green Creep and makes wide turns due to its momentum. It can also perform the following attacks:

* Spits out 5 Small Maggots.
	+ Any Small Maggots it walks into are killed.
	+ Unlike its other attacks, Chimera can perform this one without interrupting its chase and its built up speed.
* Spits out a Sick Boom Fly and throws it towards Isaac.
* Jumps twice towards Isaac, shooting out a radius of 8 tears on the first landing and 4 rock waves in diagonal directions on the second landing.
* Shoots out 8  shots towards where Isaac is predicted to move. The landing position of each projectile is marked on the ground.

### Phase 2

Once its HP has dropped to about half, it makes a final charge towards Isaac before tripping and dividing the head and body into separate entities. It will take increasingly reduced damage as it approaches 50% HP until it transitions phases.

* The head continuously makes leaps towards Isaac and slides a distance after landing while leaving a trail of damaging Red Creep. It can also perform the following attacks:
	+ Shoots out 4 spreads of 5 projectiles in Isaac's direction.
	+ Performs three quick dashes, similar to Dingle, leaving Red Creep. The first 2 dashes are towards Isaac while the final dash is towards its body. After completing the final dash the body can pick the head up and throw it at Isaac, leaving a trail of projectiles as it travels and creating a burst of projectiles where the head collides with a wall.
		- If the body is performing another attack during the head's charges, the head will charge at Isaac for its third charge instead.
	+ If the body dies before the head, it continuously makes long charges at Isaac, bouncing off any walls while also leaving Red Creep.

* The body continues to chase Isaac like the first phase but at a slower pace. It can also perform the following attacks:
	+ Fires a green-hued  beam downwards if Isaac is directly above or below it. It is propelled upwards by this beam until it hits the wall.
	+ Runs quickly towards Isaac building momentum before leaping and rolling around the room bouncing off walls, similar to The Cage.
	+ If the head dies before the body, the body continuously rolls around like The Cage for the rest of the battle.
