Gensokyo/Medicine Melancholy

Medicine Melancholy is a Tier 3 Hardmode boss.

Spawn
Medicine does not spawn naturally. Instead, she can be summoned using Black Bile.

Behavior
Medicine alternates between a movement phase and a stationary phase. She uses one of four spellcards, depending on her remaining health. Unless mentioned otherwise, she only attacks during the stationary phase.
 * Poison Sign "Melancholy Poison": Medicine shoots several poison orbs at the player. After a short delay, these orbs explode into stationary poisonous clouds, and Medicine shoots a wave of poisonous petals in all directions.
 * Confusion "Into Delirium": Medicine shoots poison orbs in all directions, creating a circle of poison clouds around herself. She then shoots bullets in all directions; while hidden by the poison clouds, the bullets become larger and have their speed increased.
 * Doll Sign "Broken Doll": During both movement and stationary phase, Medicine shoots bullets in a spiralling pattern. Shortly after the start of this phase, her doll begins emitting poison clouds and starts chasing the player.
 * "Poisoned Heart": Medicine shoots multiple salvos of poison orbs, covering a large area with poisonous clouds. Meanwhile, she targets the player with a stream of normal bullets.

Trivia

 * While Medicine is alive, a remix of Poison Body ~ Forsaken Doll, her theme from Phantasmagoria of Flower View, will play. The remix was composed by Ümbra.
