Guide:Lunatic Cultist strategies

The Lunatic Cultist a post-Golem boss. Defeating it will summon the Celestial Towers. = Summoning = He spawns after the 4 other Cultists are slain. The Lunatic Cultist will not take any damage when he first spawns. After he moves away from his spawn point he will take damage.

First form
The Lunatic Cultist will attack the player with ranged magic attacks; purple fireballs and rotating ice balls.

Second Form
When he is at about half health, the Lunatic Cultist will spawn four invincible clones (these do not affect a player's homing attacks). He can also spawn a Wyvern type creature called the Phantasm Dragon

Gearing Up
This boss can be very difficult to defeat, even with the gear used to beat Plantera and the Golem. Gear dropped from the Pumpkin Moon and Frost Moon events is recommended. Gear dropped from Duke Fishron and the Martian Madness event is ideal, and will make this fight much easier. Homing ranged attacks are preferable. The UFO Moun t is also recommended to easily dodge the Lunatic Cultist's attacks.

Weapons
Flairon is the preferred choice for melee characters. The Terra Blade can be used as well if you prefer not to defeat Duke Fishron first, but you should be cautious about aiming well. The Influx Waver will work even better because of it's multi-hit ability, if you are willing to take on the Martian Madness event before fighting this boss. The Eye of Cthulhu (yoyo), deals high damage and will help with taking out the Lunatic Cultist and the Phantasm Dragon he summons. Also, use Vampire Knives. It is very effective, as you can stand still and shoot and still not lose much life.

For bullet class rangers use the Chain Gun with Chlorophyte Bullets as it will track/follow the Lunatic Cultist and is a good weapon to fight the Lunar Pillars' minions when you have killed the Lunatic Cultist. For rocket class rangers, use the Snowman Cannon, as it's projectiles will also home in on the Cultist. It is very useful in taking out the Phantasm Dragon in a few short seconds, because the rockets do splash damage and will hit multiple segments of the Dragon at the same time. For arrow class rangers, the Tsunami bow (if you can get it) or the Chlorophyte Shotbow with Holy Arrows are recommended. Using the Piranha Gun will help as it deals continuous damage to the Cultist and prevents him from summoning minions.

The Razorblade Typhoon is recommended for mage characters. Mage characters can use the healing variant of the Spectre Armor with the Leaf Blower as well. The Laser Machinegun will work even better if you can get it. With this setup you can stay still and not lose much life due to the healing effect.

For summoners, the Deadly Sphere staff and the Xeno Staff are good choices. Because the Dungeon entrance has a flat ground, it would also be wise to use the Pygmy Staff.

Armor
For melee users, use Beetle Armor with the shell as it gives more defense. Ranged users should use Shroomite Armor with the preferred headpiece. For mages, the above setup (Spectre Armor with the hood) is good. Summoners can use Spooky Armor or Tiki Armor, but Tiki Armor is best to use for summoners in this situation. If you have already defeated the Moon Lord then use the fragments according to your character class.

Accessories

 * The Ankh Shield is not needed, but the defense it gives will definitely help (try to get the Warding modifier on it for a grand total of 8 defense for an accessory). The Flesh Knuckles, though hard to get, has more defense than the Ankh Shield and will greatly help as it can give an extra 11 defense if reforged with the Warding modifier.
 * Lightning Boots or Frostspark Boots can be useful to dodge the attacks as well.
 * The Yoyo Glove or Yoyo Bag can be extremely useful for melee characters with The Eye of Cthulhu as it can double the damage output
 * The Avenger Emblem or Destroyer Emblem can be useful, though you can just use the emblem that suits your attack style (eg. Warrior Emblem for melee users)
 * For magic users, the Mana Flower and/or Celestial Cuffs are great choices, especially with the Leaf Blower (don't be fooled by the low rarity on both accessories)as you can continuously hit the Lunatic Cultist without pause.
 * The Cross Necklace can help when battling the Phantasm Dragon, as it is a Wyvern-like enemy that hits hard and fast.
