    The TerraprismaTerraprisma is a powerful summon weapon that is dropped from the Empress of Light only when all damage dealt to the Empress occurs during the day. The Empress enrages during the daytime, causing all of her attacks to instantly kill the player, which vastly increases the difficulty of the boss fight.

    In order to spawn the Empress of Light, you need to kill a Prismatic LacewingPrismatic Lacewing. They spawn in the Hallow after Plantera has been killed and only spawn between dusk and midnight (7:30 PM and 12:00 AM). An easy way to ensure that all damage is dealt during the day is to use a Bug NetBug Net to catch a Prismatic Lacewing during the night and then release and kill it during the day.

    The Fight[]

    Differences between Night and Day[]

    The Empress of Light will enrage if still alive or if summoned during the daytime, causing her attacks to do tens of thousands of damage, similar to the Dungeon Guardian, instantly killing players who are hit by her attacks. This enraged state is indicated by her attacks turning from rainbow to bright yellow.


    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. Because she is 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 8 rays of light 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. Because she is enraged, extra swords are summoned, and they will launch faster.

    Attack Pattern[]

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

    First phase[]

    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[]

    When the Empress is below half 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 6 evenly spaced 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
    4. Ethereal Lance
    5. Everlasting Rainbow
    6. Prismatic Bolts
    7. Sun Dance
    8. Ethereal Lance
    9. Dash Attack
    10. 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[]

    General Tips[]

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

    • For nocturnal bosses, starting the battle just after the sun sets (7:30 PM) will provide the maximum amount of time to defeat the boss. In Hardmode, the Moon CharmMoon Charm and/or Moon StoneMoon Stone and their upgrades are also useful at night.
    • Boss battles can be won or lost before the battle ever starts. Choose your equipment and have it ready; find and/or make potions and placed buffs; use the highest-tier food you have available; set up an arena appropriate to the boss; learn the strategies for the boss you're facing.
    • 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 Statues will provide a significant defensive boost. Garden GnomeGarden Gnomes and (if underground) proper torch placement will reduce damage taken and increase damage dealt due to the luck. Note Torch God's Favor helps with this. HoneyHoney pools can also be used for extra health regeneration.
    • 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 around a stack of the highest-tier healing potion available, as relying only on natural Health Regeneration is not a good idea. Depending on the game stage, this can include items such as Mushrooms or Honeyfins. As of, Restoration Potions are healing potions with a shorter cooldown.
      • Likewise carry mana potions, if you use Magic.
      • The Strange BrewStrange Brew is also an option, but its weak healing effect *will* trigger the Potion Sickness cooldown as well as Mana Sickness. Before, Restoration potions can save a slot, but will likewise trigger both cooldowns.
    • It is suggested to build houses for the DryadDryad and the NurseNurse NPCs in your arena. The former casts the Dryad's BlessingDryad's Blessing 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 helps 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 Station, Ammo BoxAmmo Box, Crystal BallCrystal Ball, Bewitching TableBewitching Table, and Slice of CakeSlice of Cake 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 SharpenedSharpened, Ammo Box (buff)Ammo Box, ClairvoyanceClairvoyance, BewitchedBewitched, and Sugar RushSugar Rush, respectively.

    Terrain Preparation[]

    A long straight section of terrain made of platforms, with a great amount of vertical space above is recommended. A few layers of platforms spaced vertically widely apart is also useful. Its up to the player how much horizontal space is required, but vertical space is key for this fight, as many of the attack patterns involve dodging by flying up or falling down. Its better to fight her in Medium or Large worlds, as Small worlds do not provide enough space to dodge her attacks effectively, and can cause the player to get stuck in low gravity and get hit, or spawn Wyverns in, which if left unchecked, can easily snipe a player.

    Gearing Up[]


    Because this fight is particularly difficult, it is recommended to use high tier armor. As Defense is useless in this fight, it is also recommended to maximize DPS instead.

    • If you are not confident of your abilities to dodge the Empress of Light's attacks, or are using non-endgame gear, the use of Hallowed Plate MailHallowed armor for the Holy ProtectionHoly Protection buff is highly recommended, which allows the player to dodge a hit once every 30 seconds.
      • A good way to approach the fight with Hallowed armor is to try keep the Holy Protection buff active as long as possible by dodging her attacks, rather than being aggressive due to the presence of a safety net. This will help your general understanding of her attack patterns and how to dodge them, while giving you a a sort of safety net, in case you make a mistake or are affected by bad luck.
    • If you are confident in your abilities to dodge her attacks, then the following sets help maximize damage output -


    • The Terra BladeTerra Blade and the SeedlerSeedler make great choices. Each sword shoots projectiles, a necessity for this boss fight. The Seedler is a little trickier to use however, as it needs to be aimed more carefully.
    • The Eye of CthulhuThe Eye of Cthulhu is the best yoyo available for this fight, but it is incredibly dangerous due to its range.
    • While its healing ability is a little useless here, the Vampire KnivesVampire Knives are still good due to the fact it launches multiple projectiles.
      • This weapon can only be found in Crimson worlds however.
    • The Scourge of the CorruptorScourge of the Corruptor is useful due to the tiny eaters and can be used to hurt the EoL as well as other enemies.
      • This item can only obtained in Corruption Worlds however.
    • If GolemGolem has been defeated, the Flying DragonFlying Dragon, is very useful.
      • However, the enemy that drops it, BetsyBetsy, is very dangerous.
    • The FlaironFlairon is a very useful weapon due to its damage and homing capabilities. It can even be obtained before fighting the Mechanical Bosses if the player is careful.
    • The Tactical ShotgunTactical Shotgun, when used with Chlorophyte BulletChlorophyte Bullets, can tear down the boss pretty quickly.
    • The Daedalus StormbowDaedalus Stormbow, when paired with Holy ArrowHoly Arrows, can deal a good amount of damage to the boss.
    • The Chlorophyte ShotbowChlorophyte Shotbow, when used with Holy ArrowHoly Arrows, can tear down the boss. Ichor ArrowIchor Arrows are also good.
    • The Pulse BowPulse Bow is one of the best bows in the game and should be used with Venom ArrowVenom Arrows for damage, or the Endless QuiverEndless Quiver for ammo conservation. Keep in mind that the weapon cancels out debuffs.
    • The TsunamiTsunami can decimate the EoL and should be used with Holy ArrowHoly Arrows or Ichor ArrowIchor Arrows. This can be obtained before the Mechanical Bosses.
    • If the Martian Madness event has been defeated, the XenopopperXenopopper should be used with Chlorophyte BulletChlorophyte Bullets as this can destroy the boss.
    • If the Frost Moon event has been defeated, the Chain GunChain Gun can be used with Crystal BulletCrystal Bullets or Chlorophyte BulletChlorophyte Bullets. This weapon has an absurd rate of fire and therefore high DPS.
    • The Piranha GunPiranha Gun is another good option, providing consistent and strong DPS with homing capabilities.
    • The Snowman CannonSnowman Cannon is a very powerful weapon, and has higher DPS than the Piranha GunPiranha Gun, but doesn't have consistent damage. It should be used with Rocket IIIRocket III or Mini Nuke IMini Nuke I.
    • The Electrosphere LauncherElectrosphere Launcher is great to use against the Empress of Light while she's using her Sun Dance. This should be used with Rocket IIIRocket III or Mini Nuke IMini Nuke I.
    • The Aerial BaneAerial Bane is true to its name and can take out the EoL pretty quickly. Use with the Endless QuiverEndless Quiver.

    For Magic users:[]

    • Betsy's WrathBetsy's Wrath is a great secondary weapon due to its powerful defense-lowering Debuff.
    • The Blizzard StaffBlizzard Staff is a very good choice due to its consistent and high DPS. The RazorpineRazorpine is an alternative with roughly the same mana cost/DPS ratio but shorter range. The Laser MachinegunLaser Machinegun is a weaker version of both but can still be viable.
    • The Razorblade TyphoonRazorblade Typhoon may be utilized due to its homing capabilities and long range, however it's very lacking DPS, making it a weaker choice as a main weapon.
    • For Summoners intending to get the Terraprisma, there are a variety of options available depending on the players progress -
    • The Deadly Sphere StaffDeadly Sphere Staff is a viable option, should the player have defeated a Solar Eclipse
    • The Sanguine StaffSanguine Staff is one of the best staves to use due its near perfect tracking and good damage output, allowing you to focus on dodging her attacks better.
    • The Desert Tiger StaffDesert Tiger Staff can be used, but isn't recommended, due to it being a ground summon.
    • The Raven StaffRaven Staff is the highest damaging staff available pre-Golem, and can be used for good DPS. However, its tracking is subpar, which can drag out the fight unnecessarily.
    • If the Lunatic CultistLunatic Cultist and Stardust PillarStardust Pillar have been defeated, then its recommended to use the Stardust Dragon StaffStardust Dragon Staff for its very high DPS.
    • Regardless of choice of minion, its recommended to fight the Empress of Light in the nighttime before hand, in order to gain the KaleidoscopeKaleidoscope, the best whip in the game. It enables minions to deal critical hits, and has a large range, allowing you to greatly increase the DPS of your minions.


    • Wings are highly recommended. The Fishron WingsFishron Wings or Betsy's WingsBetsy's Wings are the best wings available for the fight. Empress Wings are also useful if the player has beaten her during the night due to their high upward acceleration. Endgame players can use the Lunar Wings (Solar WingsSolar Wings, Stardust WingsStardust Wings, Nebula MantleNebula Mantle, and Vortex BoosterVortex Booster) or the Celestial StarboardCelestial Starboard instead. If nothing else, the player can use the Flame WingsFlame Wings, or HoverboardHoverboard at the bare minimum.
      • Its also recommended to use the Soaring InsigniaSoaring Insignia along with the wings for greatly increased mobility and infinite flight. Due to the nature of infinite flight, Wing choice can be made based on special abilities alone, making the HoverboardHoverboard a viable choice.
    • The Mechanical GloveMechanical Glove and its tinkers is a useful accessory for using Whips, giving them autoswing and boosting secondary melee weapons used after tagging the Empress.
      • However, the melee bonuses do not apply to Whips, and one may prefer using the Berserker's GloveBerserker's Glove instead, which remains useful for other boss fights as well.
    • The Yoyo BagYoyo Bag is a must when using a yoyo for the fight.
    • 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 Confusion can also be used for added dodge chance.
      • While the Brain of ConfusionBrain of Confusion and Master Ninja GearMaster Ninja Gear can allow a player to dodge an attack that would normally instantly kill them, these dodges are chance-based. This makes them inconsistent compared to other dodges such as that granted by the Hallowed Armor.
      • However, these dodges take priority over Holy ProtectionHoly Protection, allowing you to preserve the guaranteed dodge for longer. Stacking them is a useful way to try and keep Holy Protection active for longer as the guaranteed dodge.
      • Using the Cross NecklaceCross Necklace or the Star VeilStar Veil extends the invincibility frames to 2 seconds, allowing you to phase through her attacks for a significant amount of time, which is extremely useful if the player becomes trapped between multiple attacks.
    • As a ranger, equipping both the Recon ScopeRecon Scope and the Sniper ScopeSniper Scope will greatly increase DPS. The Magic QuiverMagic Quiver and its tinkers should be used if the player is using a bow as their main weapon.
    • The Celestial ShellCelestial Shell is a very good choice for all classes due to its large boosts to both offensive and defensive stats.
    • The Celestial EmblemCelestial Emblem 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 along with increased damage.
    • The Amphibian BootsAmphibian Boots give a very noticeable ascent speed boost to Wings 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.
    • Shields are not recommended for this fight at all, and can be forgone in favor of a mobility or damage boosting accessory.
