Guide:Lunatic Cultist strategies

The Lunatic Cultist is a worshipper to the Moon Lord. = Summoning = He spawns after the 4 other Cultists are slain. Players have a short window to get an explosive off when the cultist first spawns.

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 weak Wyvern type creature called the Phantasm Dragon = Gearing Up = Players should not have much difficulty defeating this boss with the gear used to beat Plantera and the Golem. Ranged attacks are preferable.

Weapons
Terra Blade is the preferred choice for melee characters. Also use The Eye of Cthulhu (yoyo), which deals high damage and will help with taking out the Lunatic Cultist and the Phantasm Dragon he summons. For bullet class rangers use the Chain Gun with Chlorophyte Bullets as it will allow you to have a good weapon to fight the Lunar Pillars' minions when you have killed the Lunatic Cultist. Also use Vampire Knives. It is not effective however if you stand still and shoot, you will not lose so much life.The Razorblade Typhoon is recommended. Mages can use the healing variant of the Spectre Armor with the Leaf Blower. With this setup you can stay still and not lose much life due to the healing effect. For summoners, the Deadly Sphere staff is a good choice. Because the Dungeon entrance has a flat ground, it would be wise to also 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.

Terrain Preparation
Do NOT take the floor or roof off the Dungeon in preparation for the battle as Cultists may never spawn in your world even if you put the floor/roof back. This somewhat limits your terrain preparation.

Accessories

 * The Ankh Shield is not needed, but the defense it gives will definetly help (try to get the Warding modifier on it for a grand total of 8 defense for an accessory).
 * 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)
 * The Cross Necklace can help when battling the Phantasm Dragon, as it is a Wyvern-like enemy that hits hard and fast.
