Blue Cultist Archer

s are Hardmode, post-Golem monsters that spawn in a pair alongside a pair of Cultist Devotes 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). Until either the s or Cultist Devotes are damaged they are passive and deal no damage to players, meaning players can walk through them without the attack beginning.

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.
 * Under normal circumstances, the s will not despawn. If there is a clear path to the player, they can follow them great distances.
