The Perforators are a group of Pre-Hardmode bosses consisting of the Perforator Hive and three worms. The hive is summoned by killing a Perforator Cyst or using a Bloody Worm Food in The Crimson.

This guide will mention items exclusive to Revengeance Mode with no special formatting and will follow the intended progression.

Terrain Preparation

Flattening the ground in the Crimson and placing a platform about 25 blocks high will work for dodging the Hive's dashes and projectiles, as well as the worms.

While The Perforators will enrage on the surface and have faster attacks, this can be easily worked around due to the surface's more open space, allowing for more freedom and easy dodging.

Gearing up



  • The Shield of Cthulhu provides a dash that can be helpful for avoiding Blood Geysers and Ichor Shots.
  • Terraspark Boots provide you with extra speed and multiple other boosts, which can be useful for dodging both the hive and the worms.
  • Using a double jump accessory such as the Sandstorm in a Balloon or its variants is great for mobility and dodging the worms' charges.
    • Alternatively, the player can use Fledgling Wings instead, trading velocity and range for the ability to glide.
  • The Aero Stone, Frog Leg and Magiluminescence are all movement accessories that can help dodge the boss' attacks.
  • The Rover Drive is a great defensive accessory, granting 10 defense and a barrier that can absorb up to 20 damage.
  • The Gladiator's Locket can provide some useful healing off the second worm's several segments.
  • The Brain of Confusion is a good accessory for all classes, granting the player the ability to dodge an attack every 90 seconds and some damage boosts.
  • Using the Laudanum is especially useful against The Perforator Hive's Ichor Shots, granting the player 25 defense while under the effects of the Ichor debuff.
  • Ranged players can consider using the Rusty Medallion for its acidic droplets, which can be effective against the worms.
  • Mages should use the Celestial Cuffs and/or Mana Flower to keep their mana pool in check.
  • Summoners can boost their damage output with the Spirit Glyph and Voltaic Jelly.
    • The Feral Claws can also be used to increase the speed of whips and other melee weapons.
  • The Raider's Talisman, Coin of Deceit, Rotten Dogtooth and Silencing Sheath are all great options for Rogues.



  • The Volcano is an excellent option for all parts of the fight, easily hitting the hive and quickly disposing of the worms.
  • The Bladecrest Oathsword's projectile deals considerable damage to the hive and worms.
  • The Old Lord Claymore is great for doing damage when dashing through the worms while also gaining immunity frames.
  • The Flamarang is a hard-hitting boomerang which performs very well at this part of the game.


  • The Magna Cannon is another extremely powerful weapon for all parts of the fight.
  • The Firestorm Cannon is the best option for this fight and can deal both high single target and grouped damage with its two attacks.
  • The Molten Fury paired with Hellfire Arrows can deal high damage to the boss.
  • The Fungicide is a good option for dealing with the big amount of enemies spawned during the fight.
  • The Star Cannon will be extremely effective against all three of the worms but requires Fallen Stars which may be difficult to get at this stage of the game.


  • The Hellwing Staff does phenomenal damage throughout all parts of the fight.
  • The Flare Bolt can do great damage to both the Hive and the worms.
  • The Sky Glaze is a similarly powerful option, raining feathers down on the hive and worms.
  • The Demon Scythe can deal with the worms easily with its piercing and high damage.


  • The Cinder Blossom Staff and Deathstare Rod are recommended as means of having damage alongside the player's other minions.
  • The Vile Feeder and Scab Ripper are good against the hive itself.
  • The Brittle Star Staff is very effective on this boss, particularly against the worms.
    • Be sure to not leave any of the crawlers attacking the hive when a worm is alive, so as to not spawn the other worms before the player is prepared to deal with them.
  • Tavernkeep Rods are useful sentries that can boost the DPS output of summoners.
    • By constantly resummoning the sentries, one could exploit them instantly firing when summoned to greatly increase their damage output.
    • Alternatively, the player may also use the Rusty Beacon Prototype, which can be especially useful against the worms.
  • Using the Snapthorn is a solid way to deal active damage and make minion targeting easier.


  • The Sand Dollar is an excellent option with its stealth strike.
  • The Ashen Stalactite's stealth strike is also a good alternative.
  • The Infernal Kris can deal considerable damage to the worms with its piercing and debuff.
  • The Infested Clawmerang's stealth strike is very powerful and will grant the player the Mushy buff.
  • While risky due to its low range, the Mycoroot does heavy damage to the Hive itself and can also grant the Mushy buff.


The Fight

Once the Hive is summoned, it will start by hovering over you, shooting a rain of Blood Geysers or Ichor Shots into the air that inflict the Burning Blood and Ichor debuffs respectively. The projectiles are shot upward, then spread as they fall, covering a large area. There are several projectiles fired at once, of which the outside will fall first. You can run from the rain, by moving the opposite direction the projectiles were shot in. Alternatively, you can look for the gaps in between the projectiles, and carefully maneuver through them.

While below 70% health and no worms are alive, the hive will position itself above the player every 10 seconds and fire a spread of Ichor Blobs down on them, which create a lingering hazard that lasts several seconds. The player should move to avoid these shots and attempt to stay as far away from the blobs as possible so that they have sufficient room to move around. If possible, the player should attempt to have this attack occur on the far ends of the arena, or on the ground beneath the upper platform so as to keep them out of the way.

The three worms spawn at three separate health increments; the small worm spawns when the hive drops to 75% health; the medium worm spawns at 50% health; and the large worm at 25%. The worms behave like any other worm, burrowing through blocks to attack you. However, each worm has different attributes:

  • The small worm behaves like any other worm enemy, moving a bit quicker than the other worms.
  • The medium worm splits in a manner similar to the Eater of Worlds.
  • The large worm can burrow and lunge at players, which can be dodged by simply going in the opposite direction it is coming from.

The larger worms are stronger but move slower. The worms also get more aggressive as their health depletes. It is recommended to have your minimap open to track the worms' positions and to target each worm as it spawns. When the worms spawn, hold your position and keep dodging the hive's projectile rain. Jump or fall and dash in the opposite direction to dodge the worms' charges, but make sure to compensate for the hive's projectiles. Continue doing this while attacking the worm until it dies. Keep in mind that while the large worm is alive, the hive will take no damage.

In Expert Mode, the worms move and turn faster, so you must be more careful while dodging the worms. Furthermore, the hive will become invulnerable while the largest worm is alive, forcing you to defeat it in order to finish the fight.

In Revengeance Mode, the hive will retain its previous abilities and will gain the ability to charge at you with speed while a worm isn't alive. To dodge this attack, let the hive level itself with you, then jump or fall as it gets close. Accessories that boost jump speed and/or height help with dodging the charging. Once a worm spawns, it will stop charging but will gain increased acceleration.

In Death Mode, the hive shoots more often, is more aggressive and will hover closer to you if more than one worm is alive. It is more important in this mode that you target the worms to avoid interception by the hive. The worms also have more segments that are larger.
