The Lunatic Cultist is a Hardmode boss. Defeating it is important to progression, as it drops the Ancient Manipulator and triggers the Lunar Events, both of which are important to summoning the Moon Lord.
The Lunatic Cultist is summoned by killing the four Cultists at the Dungeon entrance, or by using an Eidolon Tablet when the Cultists are not alive and the Lunar Events are not active.

Will shoot 8 large deathrays around itself in an octagonal pattern, telegraphed by dark purple lines. Small Ancient Dooms will fly out in between the deathrays, forcing the player to dodge while in the safe spot. If the player moves too far away, the Lunatic Cultist will teleport somewhere near them before continuing the Desperation. After shooting 4 rings of deathrays, the Lunatic Cultist emits 4 harmless colored rings themed after the Pillars and dies.
