Guide:Lunar Events strategies

The Lunar Events start immediately after beating the Lunatic Cultist boss. Four Celestial Pillars will spawn on the map, each corresponding to one of the four classes-- Melee, Ranged, Magic, and Summoner. Before trying to beat this event, make sure you are completely prepared, as the event cannot be canceled without entering combat.

Before You Begin
The first thing you should do after defeating the Lunatic Cultist is open your Map and note the locations of each Pillar. If you need a safe haven, teleport to spawn, as no pillars will exist at the center of the world.

Gear
Armor: These armor sets are considered to be the best choices for post-Golem players.
 * Spooky Armor or Tiki Armor for summoners. Spooky Armor is the offensive choice, but Tiki Armor sacrifices some DPS for significantly higher defense.
 * Shroomite Armor for rangers, as its bonuses allow a player's DPS to reach very high levels.
 * Spectre Armor for magic users. The Spectre Hood is recommended to help mages survive the Lunar Events.
 * Beetle Armor for melee fighters, as the two chestpieces allow a player to pursue an offensive or defensive playstyle.

Suggested Weapons:
 * The Vampire Knives will allow players to regain health if they need to.
 * A homing magic weapon paired with the Spectre Hood allows mages to heal quickly while dealing precise damage.
 * The Stardust Dragon Staff, this minion quickly takes down every pillar, speeding up the lengthy process (obtainable after defeating the Stardust Pillar)
 * The Phantasm, as it will deal huge amount of damage to pillars once they are defenseless and is the best bow in the game. (obtainable after defeating the Vortex Pillar)

Suggested Accessories:

Mounts: Towards the endgame, Wings will slowly be replaced by flying mounts. Some recommended mounts are:
 * Cosmic Car Key for all pillars except Solar
 * Shrimpy Truffle for all pillars except Solar
 * Brain Scrambler (item) for the Solar Pillar

Tips

 * If you need to escape the fight, use a Magic Mirror-type item and heal at the Nurse. Unless you log out, no progress will be lost.
 * As of 1.3.0.4, this strategy is less effective, as the Moon Lord has been given the ability to teleport when far away from the player, thus making it hard to escape him. Due to the incredible self-healing abilities of the Nurse though, she won't die immediately if hit by the Moon Lord. The Player can try to heal up and get away from the Nurse quickly, so she is out of danger and can be used for healing anytime again.

The Battle
The following sections are not written in any particular order. It is recommended to begin by fighting the pillar that is themed after your current class. This will allow you to craft weapons that fit your class.

Stardust Pillar:
The Stardust Pillar is the Summoner-themed pillar. It applies a royal blue shader to the screen.
 * Never stop moving during the battle, as nearly every enemy is capable of high-damage ranged attacks.
 * Keep your distance from the pillar, as it spawns enemies on-screen directly above it, with a special animation.
 * If the player was to build defensive barriers, they should be at least 2 block thick, as both the beams from Stargazers and the projectiles from Flow Invaders are capable of penetrating one block thick walls.

Enemies
The Flow Invader is easily the most dangerous of the creatures spawned, as it is capable of shooting projectiles at a steady pace. Continually strafe while defeating one. When the Flow Invader is killed, it will launch 1-3 projectiles at you immediately. This attack is the most crucial to dodge. The Star Cell is a melee-based enemy that resembles a blue plasma globe. It is like a Mother Slime in the sense that it spawns smaller versions of itself on death. Using the Vampire Knives on a Star Cell is recommended, as the multiple enemies will heal you for more hit-points than a single enemy. Otherwise, use a piercing attack to take out all of the cells at once. The Twinkle Popper is a ground enemy that spawns smaller versions of itself that shoot a spreading attack on death. If you are fighting in an arena with lava, the Twinkle Popper's minions will fire their attacks almost instantly. Strafe sideways and take out the Twinkle Popper with a direct attack. The Milkyway Weaver, while incapable of ranged attacks, is a worm-like creature capable of high melee damage. Its attacks are most effective while grounded, so you should stay in the air. Attack the Milkyway Weaver while it is charging you, as its head is the only weak spot. The Stargazer is a fast-moving humanoid creature that shoots a laser beam periodically. It is capable of dealing very high-damage lethal hits and should be treated with the same level of caution as a Flow Invader. Moving too quickly may cause you to run into the beam, so be cautious.
 * Flow Invader
 * Star Cell
 * Twinkle Popper
 * Milkyway Weaver
 * Stargazer

Strategy

 * As most attacks from the enemies cannot penetrate 2 block thick barriers, and the only capable enemy being the Milkyway Weaver, the player can gain easy kills by building a 2 block thick platform several blocks off the ground with minions or yoyos. By using flight, the player can also easily dispatch any Milkyway Weavers without taking serious damage.

Vortex Pillar:
The Vortex Pillar is the Ranged-themed pillar. It applies a blue-green shader to the screen.
 * Being hit with an attack from the enemies may give you the Distorted debuff, which will hinder you from moving vertically. This debuff may prove deadly if you are unable to dodge attacks. Avoid hits at all costs.
 * Like the Stardust Pillar, never stop moving to avoid the majority of the damage.
 * The pillar spawns portals in the sky that will shoot Alien Hornets. Keep your distance.

Enemies
The Vortexian does not appear to capable of ranged damage (needs confirmation), but will relentlessly pursue grounded players. They pose little threat for flying players and can be easily picked off by any class. They will also summon a portal that shoots lightning on the players location upon death. The Alien Queen shoots bullet-like projectiles at you that give the Distorted debuff. She also spawns Alien Larva that grow into the Alien Hornet. When fighting the Alien Queen, strafe vertically to avoid the projectiles and use a area-of-effect weapon to destroy the Alien Larva before they can transform. She is the highest-threat enemy and should be killed as quickly as possible. The Alien Hornet can spawn from an Alien Larva or a vortex from the pillar. They are fast-moving creatures that should be taken out quickly. They do not pose a major threat unless attacking in numbers, so use a piercing or area-of-effect weapon to kill the swarms. The Storm Diver is a floating humanoid creature that wields a shotgun similar to the Tactical Shotgun in function and sound. They are capable of decent damage but easily miss their attacks. Pick them off early to avoid problems. A headphone user can use the shotgun blast sound to determine its location.
 * Vortexian
 * Alien Queen and Alien Larva
 * Alien Hornet
 * Storm Diver

Strategy

 * One of the easiest ways to defeat the Vortex pillar is to dig a 2*4 tunnel directly under the Pillar, and attacking upwards. Almost all enemies can't get into the hole, which should allow a player with a high attack rate weapon easy survivability. Optimal weapon is the Phantasm with Endless Quiver, but if not possible, Megashark with Endless Musket Pouch works well

Nebula Pillar:
The Nebula Pillar is the mage-themed pillar. It applies a magenta-purple shader to the screen.
 * The Evolution Beast is deadly to a grounded character. Always stay in the air.
 * Most enemies are extremely mobile and some avoid damage by teleporting. Stay on the move or you will die very quickly.
 * If you are blinded by an attack, kill the nearest Brain Suckler to regain your sight. It should be on your head. Don't let the blindness stop you from moving, as that will quickly lead to your demise.
 * Unlike the other pillars, the Nebula Pillar does not perform any special attacks or actions in combat. Use this to your advantage and stay near the pillar.

Enemies
The Nebula Floater is the most dangerous of the group. It floats around, shooting lasers that do high damage. On most hits, it will teleport to a different part of the screen, making it very difficult to kill. The Nebula Floater will shoot a laser immediately after teleporting and periodically afterwards. When fighting it, use a crowd-control weapon and constantly be prepared to dodge and change direction. The Brain Suckler is a melee-based creature that is extremely fast and hard to hit. If it lands a hit, you will gain the Obstructed debuff until you kill it. This debuff almost completely blackens your screen, making it near impossible to dodge attacks. Always kill this enemy when it appears on screen, before it gets anywhere near melee range. Homing weapons help to hit the small enemy. The Predictor is a ground creature that throws a spread of star-shaped projectiles as its main attack. When fighting, do not stray too close to the ground. At a higher altitude, it is easy to dodge the Predictor's attacks. They are easy to kill otherwise. The Evolution Beast preys on grounded players with a fast charging attack. For this reason, wings or a mount are essential. If you are in the air, the Evolution Beast will shoot a slow nebula sphere that homes in on the player and cannot be destroyed by an attack. This is another reason why staying on the move is essential, as the it will fade away after a moderate length of time. Only engage the enemy in the air-- never in grounded melee combat.
 * Nebula Floater
 * Brain Suckler
 * Predictor
 * Evolution Beast

Strategy

 * The main sources of damage, Evolution Beasts and Nebula Floaters, can be nullified by building a small box in the sky. As Nebula Floaters cannot fire lasers through blocks, building such structure forces them to ram the player, making them highly suceptible to wall penetrating attacks and minion damage. If the box is sufficiently high, Evolution Beasts will not spawn, thus avoiding their wall penetrating Nebula Spheres.

Solar Pillar:
The Solar Pillar is the melee-based pillar. It applies a yellowish-orange shader to the screen.
 * Unlike every other Lunar Event pillar, the player should not stay in the air. This will aggro the Crawltipede, which can kill players in 2-4 hits and is very hard to dodge.
 * The Scutlix Mount is recommended for this fight, as it disables your flying while still giving you incredible mobility and an extra ranged attack. Scutlix is preferable because it has a low acceleration time and a fast speed.
 * Although flying is out of the question, staying on the move is still a must due to the number of charge attacks that enemies will employ against you.

Enemies
The Selenian is a humanoid sword-wielding enemy that can curl up and charge at you. However, while curled up, most projectiles that you fire at it will be reflected towards you, including all bullets and arrows. This enemy is the counter of the ranger class-- if you play a ranger, only attack the Selenian if it is not curled up. The Drakomire is a ground-based enemy that can spawn with a Drakanian riding it. The Drakomire beast can charge the player if nothing is riding it. If the Drakanian is riding it, the pair can do incredible damage. Use a crowd-control weapon to take out the pair, and utilize knockback to keep them out of melee distance. The Corite is a fast-moving enemy that resembles a Meteor Head. It attacks by launching itself into the sky and coming back down like a meteor, shrouded in flame. Strafe horizontally to avoid the Corite while using a homing weapon to take it out. The Sroller is the more down-to-earth version of the Corite, utilizing a weaker, more frequent rolling attack. These enemies pose the most threat when in a swarm. Use dodging and knockback to keep them at bay while using a crowd-control weapon. The Crawltipede is the deadly counter to a flying player. It only attacks players that are flying, and otherwise hovers in the air, ignoring them. To make matters worse, its only attackable spot is the bulging orb on its tail. If you are pursued by a Crawltipede, use any dash maneuvers you may have and get to the ground while attacking the general area with a homing weapon. Do not evade it by flying higher, as the Crawltipede will soon catch up and easily deal over 100 damage per hit. On the ground, they can be considered easy kills.
