Posthumous Bosses

"It's coming for vengeance..."

Posthumous Bosses are undead versions of some vanilla bosses, which can spawn randomly at night in Hard Mode if the respective living boss has been killed.

They are similar looking, but undead and also are much more difficult than their respective living bosses. The message "It's coming for vengeance..." will pop up every time an undead boss is approaching the player, and will attack approximately 1 minute after that message has popped up and if the player is at surface level.
