Spawn Conditions[edit | edit source]

The Empress of Light can be spawned by killing the special critterPrismatic LacewingPrismatic LacewingDesktop Version, which is a rare critter that spawns in the surface Hallow during the night once Plantera has been defeated in the world. As it is a rare creature, it can be detected by the Lifeform AnalyzerLifeform AnalyzerDesktop, Console, and Mobile Versions. The Prismatic Lacewing can only spawn between 7:30 PM and 12:00 AM, and only one can have spawned in the world at any given time.

Like most critters, the Prismatic Lacewing can be caught with any bug net, which can then be released, and killed, by the player manually. This can be used to spawn the boss at a more desired place and time. However, the critter will almost instantly despawn if released outside of the Hallow, so it must be killed quickly in order to summon the boss. If you want to catch multiple Lacewings in one night, it is recommended to farm for them during a Blood Moon.

The Fight[edit | edit source]

Time of Day[edit | edit source]

The Empress of Light, if summoned by a natural spawning Lacewing, will be fought at night. She will enrage if still alive or if summoned during the daytime, causing her attacks to do tens of thousands of damage, instantly killing players who are hit by her attacks. This enraged state is indicated by her attacks turning from rainbow to bright yellow.

She will always drop the TerraprismaTerraprismaDesktop Version if all damage dealt to her was during the day.

Attacks[edit | edit source]

  • Prismatic Bolts – Summons a cloud of prismatic bolts that home in on the player after a short time. These bolts do not have perfect tracking, and will miss if the player makes a sharp turn as they approach. If enraged, extra bolts are created, and they will spread out more before homing onto the player.
  • Dash Attack – Positions herself to the left or right of the player before charging horizontally in the player’s direction.
  • Sun Dance – Hovers above and slightly to the left of the player and emits 6 rays of light (8 if enraged) that slowly rotate clockwise. 3 sets of rays are created per sun dance, each positioned slightly more clockwise from the last.
  • Everlasting Rainbow – Releases a ring of 13 stars that spiral out clockwise, then spiral back in the same direction. These stars leave behind a trail of light that will damage the player.
  • Ethereal Lance – Summons a swarm of swords that launch in the direction the player was headed when they were summoned, telegraphed by colored beams. These swords are summoned behind where the player was moving, or all around the player if they were stationary. The swords do no damage until launched. If enraged, extra swords are summoned, and they will launch faster.

Attack Pattern[edit | edit source]

The Empress has set attack patterns for both of her phases.

First phase[edit | edit source]

When spawned, the Empress will hover in place for a few seconds before executing the following attacks in order:

  1. Prismatic Bolts
  2. Dash Attack
  3. Sun Dance
  4. Dash Attack
  5. Everlasting Rainbow
  6. Prismatic Bolts
  7. Dash Attack
  8. Ethereal Lance
  9. Dash Attack
  10. Everlasting Rainbow

This sequence of attacks will repeat indefinitely until the second phase starts.

Second phase[edit | edit source]

When the Empress is below half of her max health, she will disappear for a second, then reappear above the next estimated location of the player before executing a new set of attacks, with slightly shorter attack intervals than before:

  1. Ethereal Lance Ver. 2: Summons four evenly spaced waves of swords that travel across the screen, telegraphed by colored beams. The first wave travels from the left side of the screen to the right, the second from right to left, the third wave from top-left to bottom-right, and the fourth wave from top-right to bottom-left.
    • If enraged, there will instead be six waves of swords that target specific points around the player instead of traveling from one side of the screen to the other. The first wave travels from the left side of the screen to the right of the player, the second wave from the right side to the left of the player, the third wave from top side to the bottom-right of the player, the fourth wave from top side to bottom-left of the player, the fifth wave from the bottom side to top-right of the player, and the sixth wave from the bottom side to top left of the player.
  2. Prismatic Bolts
  3. Dash Attack
    • If enraged, she will cast Ethereal Lance after the dash before resuming her normal pattern (targets where the player is rather than where they will be, or do nothing if the player is stationary)
  4. Everlasting Rainbow
  5. Prismatic Bolts
  6. Sun Dance
  7. Ethereal Lance
  8. Dash Attack
  9. Prismatic Bolts (Cast in a circle around the Empress instead of a cloud directly above her)

This sequence of attacks will repeat indefinitely until she is defeated.

General Strategies[edit | edit source]

General Tips[edit | edit source]

This content is transcluded from Guide:Practical Tips § Combat.

  • Starting the battle just after the sun sets (7:30 PM) will provide the maximum amount of time to defeat nocturnal bosses. In Hardmode, the Moon CharmMoon Charm and/or Moon StoneMoon Stone are also useful at night.
  • Prepare your Boss-fighting arena with adequate lighting, CampfireCampfires and Heart LanternHeart Lanterns for health regeneration, and Star in a BottleStars in Bottles for mana regeneration if you use magic. Bast StatueBast StatuesDesktop Version will provide a significant defensive boost. Garden GnomeGarden GnomesDesktop Version will reduce damage taken and increase damage dealt due to the luck. HoneyHoney pools can also be used for extra health regeneration.
  • Desktop, Console, and Mobile Versions SunflowerSunflowers provide the Happy! buff to players within a 50-tile radius, which grants a +10% movement speed bonus and 17% reduction in enemy spawn rate.
  • Always carry at least one stack of the highest-tier healing potion available (Lesser Healing PotionLesser, Healing PotionNormal,Greater Healing PotionGreater, or Super Healing PotionSuper Healing PotionsDesktop, Console, and Mobile Versions). Relying only on natural Health Regeneration is not a good idea.
  • It is suggested to build houses for the DryadDryad and the NurseNurse NPCs in your arena. The former casts the Dryad's BlessingDryad's BlessingDesktop, Console, and Mobile Versions buff, which increases your defense and provides you with a thorns-like effect, while the latter can heal and remove debuffs instantly, at the cost of some Silver Coincoins.
  • Bosses are displayed on the Minimap: Follow the boss's icon to track it when you're struggling to find it. You can identify the boss icons by checking their respective wiki pages.
  • Once you have freed the MechanicMechanic in the Dungeon, you can use WireWire to enhance your arena with Dart TrapTraps and helpful Heart StatueHeart and Star StatueStar Statues. The former help to damage the enemies, though be careful to set them up correctly in order not to hurt yourself during the battle. The latter will spawn heart and star pickups, respectively. Connect these devices to 3 Second Timertimers.
  • It may be useful to summon and kill the Eye of Cthulhu or King Slime before summoning any harder boss in order to spawn an extra one-use pool of Hearts. Note that this will prevent any Heart Statues from spawning new Hearts.
  • Remember to use the Sharpening StationSharpening StationDesktop, Console, and Mobile Versions, Ammo BoxAmmo BoxDesktop, Console, Old-gen console, and Mobile Versions, Crystal BallCrystal Ball,Bewitching TableBewitching TableDesktop, Console, and Mobile Versions, and Slice of CakeSlice of CakeDesktop Version before you go to explore or battle bosses/invasions. These will give boosts that are useful to take, with the first four being class-specific. They give SharpenedSharpenedDesktop, Console, and Mobile Versions, Ammo Box (buff)Ammo BoxDesktop, Console, Old-gen console, and Mobile Versions, ClairvoyanceClairvoyance, BewitchedBewitchedDesktop, Console, and Mobile Versions, and Sugar RushSugar RushDesktop Version, respectively.

Terrain Preparation[edit | edit source]

Seeing how Empress of Light's moves (namely Everlasting Rainbow, Prismatic Bolts and Sun Dance) can easily trap you; a wide, a large arena is strongly suggested for the fight against her if you don't possess an infinite-flying mount. The arena should span as far as your hallowed biome can be (this doesn't matter on Expert or Master as she will always use her enraged set, so you can span your arena even to space), and you should make it longer if your hallowed biome isn't large enough. At least long rows of 3-5 platforms fairly separated from each other will do.

  • Teleporters are recommended to easily avoid getting clustered by her moves, but be wary of her dash. Her prismatic bolts should also be taken note of due to them homing quite quickly and having a fair range.
  • Fighting her in the Ocean provides a large open space to move around which can help a lot.
  • A reliable strategy to defeat the Empress during the day is to lay down Minecart Tracks in a large loop. This has a distinct advantage over using Asphalt Blocks, because enemies cannot spawn on Minecart Tracks. Booster Tracks can also be used to quickly accelerate to full speed upon summoning the Empress. This is especially helpful on Expert or Master mode since the Mechanical Cart is available.
  • Another option if you are playing on Master Mode when Minecart Tracks aren't available at the moment is to use The Black Spot Mount as it has the highest horizontal & diagonal acceleration out of all other Mounts in the game.

Gearing up[edit | edit source]

Armor[edit | edit source]

  • Hallowed MaskHallowed armor provides very solid stats and its incredible Holy Protection set bonus makes it a solid choice for all classes. This armor is especially useful when fighting her at day time when attempting to get the Terraprisma, as Holy Protection can consistently allow the player to survive the Empress' hits.
  • Beetle HelmetBeetle armor for a melee character will be better for maximum offense or defense, depending on the chest piece used.
  • The Hallowed HeadgearHallowed Headgear, Valhalla Knight's BreastplateValhalla Knight's BreastplateDesktop VersionConsole Version and Dark Artist's LeggingsDark Artist's LeggingsDesktop VersionConsole Version make for the best magic armor in the game due to Valhalla's regeneration and the solid DPS found in the other two armor pieces. The Spooky BreastplateSpooky Breastplate may be preferable instead to use two extra minions at the cost of regeneration.
  • Spooky HelmetSpooky armor is the best armor for Summoners.

Weapons[edit | edit source]

All classes can fare well with the Empress of Light.

For Melee users:[edit | edit source]

  • The Influx WaverInflux WaverDesktop, Console, and Mobile Versions is the best sword available with a fairly strong projectile that can hit three times. The SeedlerSeedlerDesktop, Console, and Mobile Versions is a weaker alternative.
  • The FlaironFlairon is also viable thanks to its good damage and homing capabilities.
  • The Eye of CthulhuThe Eye of CthulhuDesktop, Console, and Mobile Versions may also be used for good damage, although its reach is lacking.

For Ranged users:[edit | edit source]

For Magic users:[edit | edit source]

  • Betsy's WrathBetsy's WrathDesktop VersionConsole Version is ideal due to its powerful defense-lowering Debuff.
  • The Blizzard StaffBlizzard Staff is a very good choice due to its consistent and high DPS on the fight. The RazorpineRazorpine is an alternative with roughly the same mana cost/DPS ratio but shorter range. The Laser MachinegunLaser MachinegunDesktop, Console, and Mobile Versions is a weaker version of both but can still be viable.
  • The Razorblade TyphoonRazorblade Typhoon may be utilized due to its homing capabilities at long range. However its very lacking DPS makes it a bad choice as a main weapon.

For Summoners:[edit | edit source]

Summoning Weapons are great for the Empress of Light during the day due to the fact that they'll target the Empress of Light and occur consistent damage. Use Summoning Weapons if you aren't great at dodging and attacking at the same time.

  • The Xeno StaffXeno StaffDesktop, Console, and Mobile Versions is the best summoning weapon that you can use against the Empress of Light due to its constant DPS and perfect accuracy.
  • The Raven StaffRaven Staff may be used as a 'weaker alternative', losing the perfect accuracy for some more raw damage.
  • For whips, the Morning StarMorning StarDesktop Version is your best bet for boosting your minions' damage. The Dark HarvestDark HarvestDesktop Version may be utilized for you to be able to damage the Empress of Light yourself.

Accessories[edit | edit source]

  • Wings are a necessity in this fight, the Fishron WingsFishron Wings or Betsy's WingsBetsy's WingsDesktop VersionConsole Version being the best available for a boss fight.
  • The Mechanical GloveMechanical Glove is the best accessory for Whips, giving them autoswing and boosting secondary melee weapons used after tagging the Empress.
  • The Yoyo BagYoyo BagDesktop, Console, and Mobile Versions must be used for The Eye of Cthulhu.
  • The Master Ninja GearMaster Ninja Gear is an incredibly useful mobility item due to its dash alongside its dodge chance.
  • The Brain of ConfusionBrain of ConfusionDesktop, Console, and Mobile Versions and the Worm ScarfWorm ScarfDesktop, Console, and Mobile Versions are great items for survivability.
    • During day time, the Brain of ConfusionBrain of ConfusionDesktop, Console, and Mobile Versions and Master Ninja GearMaster Ninja Gear can allow a player to dodge an attack that would normally instantly kill them, especially when paired alongside Hallowed armor.
  • As a ranger, equipping both the Recon ScopeRecon ScopeDesktop Version and the Sniper ScopeSniper Scope will maximize DPS. Due to their multiplicative increases, the Magic QuiverMagic Quiver and its upgrades are slightly better choices for the TsunamiTsunami.
  • The Celestial ShellCelestial ShellDesktop, Console, and Mobile Versions is a very good choice for all classes due to its large boosts to both offensive and defensive stats.
  • The Celestial EmblemCelestial EmblemDesktop, Console, Old-gen console, and Mobile Versions is a strong magic damage accessory that can be used with Star Statues for mana regeneration.
  • The Papyrus ScarabPapyrus Scarab and the Necromantic ScrollNecromantic Scroll are good offensive summoner combat accessories, giving a total of 2 extra minion slots with better damage.
  • TheAmphibian BootsAmphibian BootsDesktop Version give a very noticeable ascent speed boost and some utility on the ground with its extra running speed. They can be used together with a Frog LegFrog Leg or one of its tinkers for even higher ascent speed.
  • The Charm of MythsCharm of Myths can be used for free by keeping it on a vanity slot and only swapping to it when a Healing Potion is used.
  • The Frozen ShieldFrozen ShieldDesktop Version is the best knockback immunity shield due to its high defense and Ice BarrierIce Barrier effect.
  • If you have already fought her at night and you are looking to challenge yourself during the day, the Soaring Insignia can help immensely if you are in a large, open space.

Potions[edit | edit source]

Others[edit | edit source]

  • The ability to teleport from the Hook of DissonanceHook of DissonanceDesktop Version and the Rod of DiscordRod of Discord can be useful to dodge hits.
  • In master mode worlds, the Hexxed Branch mount is useful to move quickly, as it very quickly reaches its max speed even while in the air. Because it cannot fly or double jump, using it without wings is not a good idea.
  • The Slimy SaddleSlimy SaddleDesktop, Console, Old-gen console, and Mobile Versions and Gelatinous PillionGelatinous PillionDesktop Version mounts allow the player to quickly descend during the fight, making them the best mounts to use alongside Wings.

Strategies[edit | edit source]

Minecart Strategy[edit | edit source]

Build a minecart rail around the whole world. After summoning the Empress of Light, ride the minecart around. The only dodging you'll do is when she starts using Prismatic Bolts, as the other attacks can't reach you.

You and What Army Strategy[edit | edit source]

Use multiple summoning items that give you attack minions. As they'll target the Empress of Light, you'll be free to focus on dodging. The Stardust Dragon is recommended for this.

You can combine the Minecart Strategy with this for extra power and dodging.
