Guide:Lunatic Cultist strategies

The Lunatic Cultist is a post-Golem boss. Defeating him will summon the Celestial Towers. While his small health bar means he'll be taken out quite quickly, his attacks can be damaging and hard to dodge.

== Being ggay == He spawns after the 4 other Cultists are slain. The Lunatic Cultist will be invincible when he first spawns. After he moves away from his spawn point, you can begin to deal damage to him.

Attack Pattern
After moving away from his spawn point, the Lunatic Cultist will begin to cycle through three attacks: Once the Lunatic Cultist is damaged enough, he adds a fourth attack, which summons in two spreads of five destroyable Ancient Light projectiles. In Expert Mode, the Cultist may also spawn Ancient Dooms that fire purple projectiles in a cross shape.
 * A rotating ball of ice that fires six shards at equal intervals before disappearing
 * Three homing fireballs that explode on impact
 * A stationary orb similar to the Magnet Sphere that summons streaks of lightning in a straight line.

After performing 4 to 5 of his attacks, the Cultist will spawn in duplicates of himself that remain stationary. If one of these duplicates is damaged (or after a certain amount of time without damaging any one of them), a Phantasm Dragon will spawn, or an Ancient Vision if a Phantasm Dragon is already present. Two duplicates will also start attacking besides him, occasionally shooting a projectile. If the real Lunatic Cultist is damaged, neither of these two powerful minions will spawn in. The amount of duplicates the Lunatic Cultist spawns in increases, the more clones you hit. It is recommended to fight the Cultist at night, as the fake cultists will glow.

Terrain Preparation
A basic arena with some rows of platforms will suffice. If the player made an arena for Skeletron, they can reuse it here.

Gearing up
While the Cultist himself doesn't require as much preparation as Plantera or Duke Fishron, killing him will start the Celestial Event, so it is better to fight with the best gear available.
