Possessed Armor

The Possessed Armor is a Hardmode enemy which spawns on the surface at night, and underground at any time. It walks quickly and casts a motion blur similar to that of the Shadow armor. It can always open doors, regardless of whether or not there is a blood moon.

Tips

 * Using weapons with a high rate of fire can slow down the Possessed Armor's movement speed significantly.

Trivia

 * Its sprite looks similar to the Ancient Cobalt armor sprite, except with the Iron armor helmet.
 * It seems to be the Hardmode equivalent to the Zombie enemy, with its high spawn rates during night and basic Fighter AI.
