Corpse Bloom

Corpse Bloom is a Mini Boss found in the Underground Jungle.

Defeating Corpse Bloom is required for the Druid NPC to spawn.

Spawn
Corpse Bloom can not be summoned through use of an item but will instead occasionally spawn anywhere in or near the Underground Jungle after Skeletron has been defeated.

No more than one may exist in the world at a time, and it will never spawn again after being defeated.

Behavior
Corpse Bloom will remain stationary throughout the fight, before attempting to move away from the player upon losing 66% of its health. It will fire out Corpse Petals to ensure that there are always 3 Corpse Petals alive at any given time. If there are 3 Corpse Petals alive simultaneously, then Corpse Bloom will instead fire a barrage of Fungi at the player which inflict the Poisoned and Oozed debuffs.

Every 25% life lost will cause the Corpse Bloom to summon an invulnerable Corpse Weed, up to three times.

When it is defeated, a status message will appear, saying: "The elusive Corpse Bloom withers and decays away..."
