Wormwood

Wormwood is a boss that appears in Downpour.

Behavior
Wormwood has several attack patterns:
 * Pops out of the water and spits a spray of tears at Isaac.
 * Occasionally, he jumps out of the water and charges towards Isaac. Shortly after jumping out, it will shoot tears in cardinal directions.
 * Once he reaches about 33% health he will execute a series of attacks.
 * Swims under Isaac and punches his tail through the ground 5 to 7 times, which can damage Isaac and leave holes in the ground.
 * Afterwards, the screen starts shaking. After a short delay, he will break through one of the walls to the left or right and charge at Isaac at a high speed. He will spawn Small Leeches as he crashes through.
 * After this attack, he resumes using his first 2 attacks.

Trivia

 * Wormwood's attack patterns bear high similarity to Pin's.
 * His name is a reference to the Biblical Wormwood. It is a star that, according to the Book of Revelation, will fall on a third of the Earth's water, which will turn the water bitter and deadly to drink.
