Pirate's Curse

The Pirate's Curse is a Hardmode enemy that spawns during the Pirate Invasion event when a Pirate Captain is defeated. It can fly and move through blocks, and if the player dies it will momentarily hover and despawn.

Trivia

 * The skeletal appearance of the NPC, the fact the NPC spawns after the Pirate Captain is killed, and the name "Pirate's Curse" all hint to the possibility that the NPC is a reference to the film The Pirates of the Caribbean: The Curse of the Black Pearl, as the film feature pirates who were cursed to never die, and appeared as skeletons in moonlight.
