Lunatic Devote

s are unique Hardmode, post-Golem enemies that spawn in a pair alongside a pair of Blue Cultist Archers and a Mysterious Tablet at the entrance to the Dungeon. Upon their defeat, the Lunatic Cultist will spawn and allow the Celestial Event to begin (once the Lunatic Cultist is defeated). They deal no damage to players no matter what happens, though once they are damaged the Blue Cultist Archers will attack players.

All four Cultists will respawn in their respective locations after one game-day if the player fails to defeat the Lunatic Cultist, if the Lunatic Cultist wasn't summoned, when the Celestial Event is completed or after the world has been closed and re-entered.

Trivia

 * White Cultist Archer, Caster and Fighter Banners all exist, but cannot be obtained under normal circumstances, as the relevant monsters do not spawn.
 * When fighting the Cultists before the Lunatic Cultist spawns, the Golem theme music will play. This is considered a relatively simple way to obtain the Golem theme with a Music Box.
