The Celestial Pillars (also known as the Lunar Pillars, Lunar Towers, and Celestial Towers) are four mini-bosses that appear during the Lunar Events, when the Lunatic Cultist has been defeated. They appear at four locations equally spaced across the map (see Pillar Spawning Mechanics), and do not move horizontally thereafter. Each pillar takes control of the map for a large area around them, around 500 tiles in each direction. The affected area will show that pillar's background and spawn the pillar's specific enemies in large numbers.

The 4 Celestial Pillars are the Vortex Pillar, the Stardust Pillar, the Nebula Pillar and the Solar Pillar. The craftable gear from the Pillars correspond to the 4 main classes in the game; Vortex for ranged, Stardust for summoner, Nebula for magic, and Solar for melee.

Initially, the Celestial Pillars have a large force field around them, which prevents them from taking any damage. In order to remove the force field, the player needs to defeat 100 / 150 enemies that correspond to that particular Pillar. After doing that, the Pillar can be damaged until it dies. Enemies will continue to spawn until the Pillar is defeated. If the player exits the game without destroying a Pillar, all damage done to it will be reset, and the kill count needed to remove the shield will also reset. However, death of player will not reset them. When finally slain, the Celestial Pillars each drop between 12 - 60 / 18 - 90 Lunar Fragments of their type.

The bosses themselves are fairly easy, having only 20000 HP each and dealing no melee damage on contact. While they may not be a direct threat, the minions they spawn can deal high amounts of damage, move very fast or shoot fast moving projectiles, inflict debuffs, and can easily swarm the player if not dealt with quickly.

Defeating each Pillar triggers the following status messages:

  • First Pillar defeated: "Your mind goes numb..."
  • Second Pillar defeated: "You are overwhelmed with pain..."
  • Third Pillar defeated: "Otherworldly voices linger around you..."
  • Fourth Pillar defeated: "Impending doom approaches..." The Moon Lord will spawn exactly 60 seconds after this message has shown.

There is no set order in which the Celestial Pillars must be defeated. However, players usually go for whichever pillar is closest or is weakest to their class. These status messages will appear from whichever Pillars are taken down first, second, third, and fourth.

After defeating all four Celestial Pillars, the screen will start to vibrate and go in and out of focus, and the music volume will lower somewhat, indicating that the Moon Lord is about to spawn. There will also be a status message saying "Impending doom approaches...". It will spawn after about a minute. It is advised to prepare during this minute.

Quick Answers

What triggers the appearance of the Celestial Pillars in Terraria? toggle section
In the game Terraria, the Celestial Pillars, including the Solar Pillar, Vortex Pillar, Nebula Pillar, and Stardust Pillar, appear during the Lunar Events. These events are triggered once the Lunatic Cultist has been defeated. Each pillar represents a different damage type in Terraria: Solar for melee, Vortex for ranged, Nebula for magic, and Stardust for summoning.

What is the significance of the 'your mind goes numb' message in relation to the Celestial Pillars? toggle section
The 'your mind goes numb' message in Terraria signifies the defeat of the first Celestial Pillar. This status message is a way to alert all players to the pillar's destruction, which may have occurred off-screen. The Celestial Pillars are a significant challenge in the game, spawning minions that can deal high amounts of damage and easily swarm the player. There is no set order in which the pillars must be defeated, so 'your mind goes numb' could refer to the defeat of any of the pillars, such as the Stardust Pillar or the Vortex Pillar.

What are the differences between the Stardust Pillar and the Vortex Pillar? toggle section
The Stardust Pillar and the Vortex Pillar are two of the four bosses in Terraria known as the Celestial Pillars. Each Pillar represents a different celestial element and has unique characteristics. The Stardust Pillar, representing a glittering celestial remnant known as 'stardust', spawns different minions compared to the Vortex Pillar. The Stardust Pillar is known for spawning enemies like the Stargazer. On the other hand, the Vortex Pillar, representing a deep celestial void known as 'vortex', spawns enemies such as the Vortexian and Storm Diver. Additionally, the weapons gained from defeating each Pillar are different. The Stardust Pillar enables the Stardust Dragon Staff and Stardust Cell Staff, while the Vortex Pillar gives the Phantasm and Vortex Beater.

What happens when a Celestial Pillar takes control of a map area? toggle section
When a Celestial Pillar takes control of a map area in Terraria, it changes the background to a pillar-specific one and spawns only pillar-specific enemies in large numbers. The pillar itself is completely stationary, apart from slowly bobbing up and down in place. Each pillar controls a circular area around it with a radius of 250 tiles or 500 feet. The area reverts back to normal once the Celestial Pillar is defeated, which requires killing a certain number of its spawned enemies to remove its protective shield.

The Vortex Pillar is the ranger-themed Celestial Pillar, with fast, mobile minions capable of projectile attacks. When nearby, the background will display a green planet with lightning. It drops Vortex Fragments after it is defeated.

It will occasionally open a portal above the player that shoots lightning or spawns 2 Alien Hornets. This attack is incredibly dangerous, especially in Expert mode, as it can reach the player almost anywhere near the pillar, rendering closed in "safe zones" useless.

The minions spawned by the Vortex Pillar usually move fast, fly towards players, and attack with long ranged projectiles.

  • Vortexians are usually pretty easy to deal with. On death they summon a portal that shoots a lightning bolt that deals relatively low damage.
  • Storm Divers shoot a small volley of projectiles that deal very high damage.
  • The Alien Queens can fire stingers that cause the Distorted debuff, which causes the player to be unable to fly upwards or fall downwards for a few seconds, by distorting gravity around them. This forces the player to only be able to move horizontally, and make them easy targets for attacks from all of the minions.
  • The Alien Queen spawns 3 Alien Larva when killed, which will grow to Alien Hornets and into more Alien Queens if they are left for too long.

The Stardust Pillar is the summoner-themed Celestial Pillar, bringing large swarms of enemies that spawn smaller, weaker entities to attack. When nearby, the background will display a cyan moon and a sparkling effect. It drops Stardust Fragments when it is defeated.

The Stardust Pillar is able to spawn enemies above the pillar on screen. The Stardust Pillar will spawn multiple energy orbs above it, and will link together with lines and then disappear, spawning in a random enemy.

Some of the minions spawned by the Stardust Pillar have abilities or attacks that occur after they die.

  • The Star Cell enemy, if killed, will split into smaller sized versions that grow into full sized versions after a few seconds, which can cause enemies to fill the screen. This can be very dangerous if the player can't dodge them effectively, or attack multiple enemies at once. However, leaving the baby Star Cells alone is an effective way to remove the Pillar's shield more quickly, since the full-grown Star Cells will contribute to the kill count needed before the pillar can take damage.
  • The Flow Invader will summon smaller creatures around it, which will shoot themselves like projectiles at the player after there are three around the Flow Invader. The smaller creatures around it will become projectiles and shoot towards the player after the Flow Invader is killed.
  • The Twinkle Popper, along with dealing contact damage, releases a small enemy called a Twinkle that chase players and explode to deal heavy damage.
  • The Milkyway Weaver is similar to the Crawltipede by flying and attacking players in midair, but it is smaller and can only be damaged from the head.
  • The Stargazer runs after players and conjures powerful lasers to damage them.

The Nebula Pillar is the mage-themed Celestial Pillar, with minions capable of flight, teleportation, and other unusual attacks and abilities. When nearby, the background will display a purple planet with beams of energy pulling debris into the sky. It drops Nebula Fragments after it's defeated.

The Nebula Pillar is the only Pillar that doesn't have any kind of attack, although it is best that the player still watch out for its minions.

  • The Brain Sucklers can attach themselves to the player, inflicting the Obstructed debuff and dealing damage.
  • The Evolution Beast shoots projectiles that chase the player and deal high damage multiple times.
  • Nebula Floater shoots lasers that move very fast and deal large amounts of damage. The Nebula Floater will teleport around the player, making it more difficult to dodge its projectiles.
  • Predictor shoots 4 fast-moving projectiles at a time that deal very high damage.

The Solar Pillar is the melee-themed Pillar, bringing minions with strong defensive abilities, heavy contact damage, and few projectile attacks. When nearby, the background will display a massive orange planet, with a shower of falling meteors.

It drops Solar Fragments after it's defeated.

The Solar Pillar will continuously spawn fireballs called Solar Fragments (not the item) from the top, which deal high contact damage.

An easy way to tell the Solar fragments with the background meteors is to open your inventory with auto pause on, the meteors that are still moving are background meteors.

  • The Corites deal larger amounts of damage and dash directly at the player when above them, plus they can travel through blocks, making them harder to escape without coming across Crawltipedes.
  • The Crawltipedes that the Solar Pillar spawns can be devastating to players using flight, as they deal high damage and are very agile. However, despite their high health, the damage they take is multiplied by 10, and they stop attacking players that land on the ground. The damage multiplication makes healing weapons like Vampire Knives extremely effective. They can only be damaged on their tail, where they have an orb that gets redder when they take more damage.
    • When fighting the Solar Pillar, take into account that the Crawltipede does not target players on blocks and platforms. The Scutlix Mount is recommended, as it allows you to stay on the ground while also providing additional weaponry (lasers).
  • The Selenian can reflect certain projectiles back towards the player and roll towards them at high speed, which all can make the fight very dangerous out in the open.
  • The Srollers can deal very high amounts of damage if they land on the player while spinning.

Notes

  • This is one of the only events, along with the Old One's Army, during which enemies don't drop coins.
  • The Nebula Pillar is the only pillar to not have an attack that damages directly, as the Solar Pillar attacks with solar flares shooting out of the top of the pillar, the Vortex Pillar summons portals that spawn Alien Hornets, and the Stardust Pillar attacks by summoning white portals that spawn any enemy.
  • Reversing gravity with a Gravitation Potion or Gravity Globe has a strange effect on a pillar's shield. Instead of being stationary around the pillar like it normally would, its vertical position changes according to its relation to the player. This is only cosmetic, as the pillar cannot be attacked when the shield appears to be removed.
  • If a pillar has no shield and the world is closed, it will have full health and the shield will be restored when the world is reopened.
  • An NPC won't try to attack the pillar even if they are in range.
  • Scenery Mixup

    The background scenery from a Hallowed Desert and Vortex Pillar combined.

    Occasionally, the background scenery of the biome the pillar is in will overlap with the background scenery that appears when near the pillar (see right).

Tips

For more elaborate strategies on defeating Celestial Pillars, including weapon and arena recommendations, see Guide:Lunar Event strategies.

All Pillars

  • A player can tell if they have reached the kill count or not by seeing if, after killing an enemy, a colored line travels from the corpse to the Pillar. When those lines stop being created, the kill count has been reached. As well, the shield surrounding the Celestial Pillars becomes more transparent as it becomes closer to breaking. If the player is using the lighting type "Color", they can look for the shockwave that the pillar sends in all directions before breaking.
  • Before starting the Lunar Events, it's worthwhile to lay a teleporter line across the map, with enough stations that the player can at least choose which pillar to approach first.
  • Some enemies can travel or attack through blocks.
  • The weapons gained from defeating the first pillar(s) can be very helpful in defeating the others. The Solar Pillar yields the Solar Eruption and Daybreak, the Vortex Pillar gives the Phantasm and Vortex Beater, the Nebula Pillar provides the Nebula Arcanum and Nebula Blaze, and the Stardust Pillar enables the Stardust Dragon Staff and Stardust Cell Staff.
    • It may be best simply to target the pillar matching the player's preferred class, thus gaining at least one powerful weapon of it.
  • Players can use the GPS to know the height of one Pillar, build/expand a nearby building to provide a firing platform at this depth, then pelt the Pillars with a Rocket Launcher, optionally backed by a Sniper Rifle. The time the rocket takes to reach pillar can be long: in a large map, a Rocket takes ~1 min to travel from the center of the map to the farthest Pillar.
  • If the player or players have acquired the Vampire Knives once a pillar's shield is destroyed the player can regenerate health extremely fast by firing the knives at point blank range at the pillar.
  • A strategy for taking out the Pillars is to stand near the edge of a pillar spawning area and to retreat and recover when at low health until its shield is down.

Vortex Pillar

  • If the player sees a swirling portal in midair, they should keep their distance and move quickly. The portal will either shoot a lightning bolt similar to the Lunatic Cultist's attack or spawn an Alien Hornet.
    • When the portal shoots a lightning bolt, there will be a blue swirling marker pointing towards the direction the lightning bolt will strike at, but they will only shoot downwards.
    • The Vortex Pillar will always spawn Alien Hornets on back-walls with a direct line towards the player if there are any on its screen. If not, it can spawn Alien Hornets anywhere within an approximate 300 block radius of the Pillar.
  • Because most of the enemies try to stay at the same elevation as the player, staying on the ground removes much of the mobility that Alien Hornets and Storm Divers have.
  • This is the only pillar where enemies or projectiles can't travel through blocks, and thus, taking cover is very effective. However, it is somewhat slow as many enemies keep their distance.
  • Avoid getting swarmed by Alien Queens, as they easily grow from Alien Larvae and Alien Hornets and the Distorted debuff greatly decreases the player's flighting and agility.

Stardust Pillar

  • Using splash-damage weapons on Star Cells is perhaps the easiest way to kill them, as it will destroy all of the split cells as well as the initial cell.
  • A quick and easy way to break the shields is to lead a Star Cell away from the Pillar, pop it into its smaller orbs, then let those orbs grow into full star cells. This creates an infinite loop, and the new ones will also count towards the counter.
  • On death, the Flow Invader will hurl up to three projectiles directly at the player. Be ready to dodge when the player kills this creature.
  • Stargazer lasers deal very high damage, but they have difficulty targeting the player without direct line of sight. Weapons that ignore terrain or can go around it will be very effective, such as Yoyos, Minions and Chlorophyte Bullets.

Nebula Pillar

  • When fighting, take caution to avoid getting hit by a Brain Suckler. They cause the Obstructed debuff, which is similar to Darkness but with a darker shader. It will persist until the player kills the Brain Suckler stuck to them, and for a moment thereafter.
  • Be very wary of Nebula Floaters. They do high damage with high accuracy, and their tendency to teleport, especially when harmed, can make them unpredictable.
    • They can also teleport directly in front of the player and fire at point blank: if the player wouldn't survive another shot and can't heal up, it may be best to retreat. Be careful when flying in a straight line, as the Floater will deal potentially fatal contact damage if it teleports in front of you.
  • Kill Evolution Beasts quickly, because once they get in range they will fire a slow but highly damaging ball of energy that tracks the player, passes through walls, can deal continuous damage, and only expires after a few seconds. These will force the player to move around into other hazards.
  • Keep an eye out for Predictors because they will stay at distance, not attempting to get close to the player, and shoot several Nebula Piercers in a similar fashion to how Storm Divers fire their shotguns.

Solar Pillar

  • While fighting the Solar Pillar enemies, it is highly recommended to stay grounded. Airborne players are easy prey for the Crawltipede minions, which do an excessive amount of damage, but only attack them.
  • If the player has a skybridge set up in their world, standing on it will allow them to shoot down at enemies on the ground and even the pillar without being targeted by the Crawltipedes. Keep in mind Srollers will still be able to jump up to the platform and roll towards the player.
  • It is highly suggested not to use bullets, arrows, or most projectiles, at least not on Selenians as they can reflect projectiles that deal the same damage they would have dealt to the enemy. However, they cannot reflect Rockets.
  • If the player has a Neptune's Shell, a combined accessory with its effect, or Gills Potions, then standing in a large pool of water under or near the pillar will allow them to move around off the ground, without being targeted by Crawltipedes. In addition, this will also cause most enemies, with the exception of Corites, to move slower, and make it easier to target them.
  • If available, the Scutlix Mount improves forward firepower and ground maneuverability considerably, making the fight much easier.
  • When fighting the Solar Pillar, try building a small building with doors, platforms, and make it two floors tall, right on the edge of where the Pillar starts spawning enemies, to help block off some enemies from swarming the player, and to force them into a small and easy to defend area. Only the Corites will fly through walls.
  • Oddly, the enemies that the Solar Pillar spawns are not immune to the On Fire! debuff.
  • Weapons such as the Possessed Hatchet or the Stardust Dragon Staff will only target the tail of Crawltipedes, and this can kill them quickly and easily, making the fight much easier.

Pillar Spawning Mechanics

When it is time for the 4 pillars to spawn, the game follows these steps: (The coordinates are in tiles)

  1. Randomly arrange the order of the 4 pillars.
  2. Multiply the width of the world by 0.2, 0.4, 0.6, and 0.8 to find rough spawn locations for the pillars, equally spaced from each other and the world's edges.
    (For example, a large world is 8400 tiles in width, so the 4 pillars will be spawned at somewhere near x=1680, x=3360, x=5040 and x=6720)
  3. For each pillar:
    1. Pick a random x1 coordinate in the range [x0 - 100, x0 + 100], where x0 represents the x coordinate of the location the Pillar was assigned to.
    2. Try to find out a possible y1 to spawn the pillar at (x1, y1). The y1 is processed from the 0' surface point to somewhere 100 tiles below the top of the world, from low to high. This place is a valid spawning space for a pillar if:
      • There are no solid blocks (doesn't include platforms and other similar tiles) in the rectangle of x coordinate [x1 - 10, x1 + 10], y coordinate [y1 - 20, y1 + 15] (the smaller the y is, the higher height the spot lies)
      • The pillar will be outside the player's sight, checking whether tiles (x1 - 10, y1), (x1 + 10, y1), (x1 - 10, y1 - 20), (x1 + 10, y1 - 20) are all outside a rectangle centered at the player with a width of 1920*1.2 pixels and a height of 1080*1.2 pixels.
    3. If a y1 works then the pillar spawns at (x1, y1).
    4. If none of the valid y1 works, go back to the first step
    5. If all steps have been run 15 times and failed, give up and just spawn at a settled point: (x0, y0 - 40), in which case the Pillar will always spawn at 80' Surface at a fixed x coordinate.

Trivia

  • All of the Celestial Pillars have a humanoid enemy. Vortex Pillar: Vortexian and Storm Diver; Stardust Pillar: Stargazer; Solar Pillar: Selenian and Drakanian; and Nebula Pillar: Predictor.
  • If the Lighting mode is set to color or white, the shield will have a distort pulse effect, making players around it have a shockwave effect. And when the shield is down, the area nearby gets the shockwave effect. When the lighting is on retro or trippy, these effects won't occur.
  • Correspondences
    • As noted above, both the craftable gear and the enemies from the Pillars, correspond to the 4 main classes in the game: Vortex = ranged, Stardust = summoner, Nebula = magic, and Solar = melee.
    • When in a Pillar's area, the entire area nearby will turn the pillar's color: Solar = orange, Vortex = teal, Nebula = magenta, Stardust = blue). This effect will only occur if the lighting mode is on "color" or "white".
    • The four pillars could also be based on the lifespan of a star: Nebula - the birth of a star, Solar - a lively star, Vortex - a collapsing star as it dies, and finally, Stardust - the remains of a star's corpse.
  • The player can spawn the 'Released Energy' (projectile spawned upon a Lunar Enemy's death) using mods. If one is spawned while there are no pillars, it will instead target the Old Man by the dungeon. However, if the Old Man is killed or not alive, the Released Energy will despawn immediately.
  • The longer the time taken to defeat a Pillar, the deeper it will sink into the ground, but very slowly.Verify
