Possessed Armor

The Possessed Armor is a hardmode enemy that spawns in Forests, (Underground) Jungle and the Underground during the night. While these enemies act like your average Zombie, they are much more powerful and are a significant threat to your NPCs. They are particularly deadly during a Blood Moon, when they have the same ability as Zombies to open doors that are not otherwise reinforced. Due to their nature, they have extremely high defense which, coupled with their high life and attack, makes them a force to be reckoned with.

Trivia

 * The spirit appears to have possessed a set of Iron armor, judging by the style. However, the color has changed significantly, perhaps a side effect of the unnatural spiritual force inhabiting it.
