"...The divine turned inside out; their gore now glistens with its perverse treachery, for all to bear witness."

The Perforators are a group of Pre-Hardmode bosses fought in The Crimson. They consist of 3 worms with varying appearances, sizes, and behaviors, and a crimson, fleshy hive.

They are the Crimson counterpart to The Hive Mind.

Spawn

The Perforators do not spawn on their own. The player can summon them manually with Bloody Worm Food or by killing a Perforator Cyst while in The Crimson. When spawning, the Perforator Hive will deal no contact damage for the first 3 seconds of its life to prevent cheap hits.

Behavior

The Perforator Hive will hover above the player and shoot falling projectiles, accelerating towards the player to attempt to actively stay above them at all times. As it loses health, it will spawn Perforator worms with different sizes, stats, and appearances. All three worms can exist at the same time as each other, and the Perforator Hive gains 30% damage reduction for each worm alive, stacking up to 90% if all three worms are left alive.

The Perforators all behave like typical worms, burrowing through blocks and charging at the player. However, if their heads are too far away from the player (18.75 / 15 / 12.5 / 10 tiles), they gain the ability to fly in order to return to the fight or reach an elevated platform more easily. Each worm has a trait that differentiates one from another, from increased speed to the ability to lunge itself above the player.

The Perforator Hive enrages outside the Crimson biome and on the Surface, increasing their maximum movement speed.

The Perforator Hive

• Fires an arcing spread of 10 / 12 / 14 / 16 Blood Geysers or Ichor Shots every 1.25-15 seconds, which inflict the Burning Blood and Ichor debuffs respectively. The type of projectile chosen is random.
  • These projectiles arc slightly upward, which then spread out and fall down to cover a large area. They can only pass through tiles within the first two seconds of being fired.
  • The fire rate is lower for every worm alive. Each worm equally reduces the fire rate by the same factor.
• When below 70% health, every 10 seconds it positions itself above the player. After 5 seconds of positioning, it drops a spread of 3 / 6 Ichor Blobs downwards, which splatter on surfaces and become stationary hazards for up to 15 seconds.
  • The Perforator Hive cannot perform this attack if one of the worms is currently alive.

The Small Perforator

• Spawns when the Perforator Hive reaches 75% health.
• This small worm is much faster than the other two.
• This worm has 6 / 8 / 9 / 10 segments in total.

The Medium Perforator

• Spawns when the Perforator Hive reaches 50% health.
• Similar to the Eater of Worlds, each segment has an individual health pool and it can split up into smaller worms when a body segment is killed.
• This worm has 12 / 14 / 15 / 16 segments in total.

The Large Perforator

• Spawns when the Perforator Hive reaches 25% health.
• Similarly to the Desert Scourge, upon reaching 50% / 75% / 100% health, The Large Perforator will occasionally burrow underground then rapidly lunge at the player before burrowing again from a height 37.5 tiles above the player.
  • This attack occurs every 4.5 / 3.5 seconds. After performing the attack, this timer resets on the apex of its lunge.
  • If the attack takes longer than 10 seconds, it will automatically reset to its default behavior.
• This worm has 16 / 22 / 25 / 28 segments in total.

In Expert Mode

• All Perforators can be enraged similarly to the hive, increasing their acceleration and speed. The enrage is linearly more effective the lower their health, up to doubled base movement.
• All Perforators gain 2, 4, or 6 segments from smallest to largest and a size increase of 10%.
• The Perforator Hive shoots 12 projectiles per volley instead of 10, and 6 Ichor Blobs instead of 3.

In Revengeance Mode

• All Perforators gain 1, 2, or 3 segments from smallest to largest and a size increase of 5%.
• The Perforator Hive shoots 14 projectiles per volley instead of 12.
• The Perforator Hive attempts to ram the player.
  • If there is only one Perforator alive, it will not ram the player but instead gain slightly increased acceleration and maximum speed.
  • It there are multiple Perforators alive, it will accelerate faster but lower its maximum speed.

In Death Mode

• All Perforators gain 1, 2, or 3 segments from smallest to largest and a size increase of 10%.
• All Perforators' enrages are more effective.
• The Perforator Hive shoots 16 projectiles per volley instead of 14.
• The Perforator Hive accelerates faster but has a lower maximum speed.

On the For the worthy seed

• Perforators are now summoned when The Perforator Hive reaches 85%, 60%, and 45% health.
• The Perforator Hive shoots double the amount of projectiles.

During the Boss Rush

• The Perforator Hive does not enrage outside of their biomes.
• The Perforators and their hive gain significantly higher acceleration.

Aftermath

• The status message "The sky is glittering with cyan light" displays, indicating that Disenchanted Aerialite Ore on Floating Islands is converted into Aerialite Ore and can now be mined.
• Aero Slimes begin spawning in the Space layer.
• Sky Crates will contain Aerialite Ores and Aerialite Bars.

Resistances

• All Perforator segments take reduced damage from most non-minion piercing projectiles. Each hit decreases the damage of the next hit by 12%, until the eighth hit onwards which deal 20% of original damage.
• All Perforator segments take 20% damage from grenade-type projectiles. A list of affected projectiles is below.

• All segments also take 50% damage from true melee hits.

Tips

For elaborate strategies on defeating the Perforators, including Weapon and Arena recommendations, see Guide:The Perforators strategies.

• Building a few layers of platforms within The Crimson will make avoiding the Perforators much easier.
  • The Perforators have extremely high speed when tunneling horizontally, and can tunnel through platforms if they reach them. Keeping platforms around 15 blocks above the ground and each other can help prevent this.
• When a Perforator worm is spawned, the player should target it until it's dead while avoiding damaging the Hive, this will make sure the player isn't overwhelmed by multiple worms at once.
  • The worms will drop hearts on death, the player should remember where they killed the worms so they can use these hearts later unless they are hurt enough to warrant their immediate use.
• The Perforator Hive will consistently float above the player, so weapons with projectiles are recommended as getting close is extremely difficult without high jump speed and vertical movement accessories.
• Because the Perforator Hive gains damage resistance for each worm alive, it's highly recommended to kill each worm as they spawn to remove the damage resistance.
• The player can fight The Perforators at the start of the game, though it is not recommended to fight these bosses until the Brain of Cthulhu is defeated, as the multi-boss fight and high damage can easily overwhelm an unprepared player.
• During Hardmode, The Perforators can be fought to get an effective amount of Ichor. This is a highly effective way to get Ichor in a Corruption world, as The Perforators can be fought on a Crimson island.

Trivia

• The Perforators' theme is Blood Coagulant, which was composed by the artists DM DOKURO and SixteenInMono.
  • This is the second of three collaborations with DM DOKURO and SixteenInMono. The other two being The Filthy Mind and Return to Slime. These themes belong to The Hive Mind and The Slime God, respectively.
  • If the Calamity Music add-on mod is disabled, Boss 2 will play instead.
• Perforation is the process of making holes in something.
• The Perforators could be considered the Crimson's version of the Eater of Worlds, while The Hive Mind could be considered the Corruption's version of the Brain of Cthulhu.
• Although difficult, it is possible to kill the Perforator Hive without defeating all or even any of the worms. If this happens, the worms will burrow away and despawn, and the Hive will still drop its loot as normal.
• The Perforators can be fought before any boss is defeated, as Perforator Cysts can spawn in The Crimson at any point of the game.
• In older versions of the mod, the Perforator Hive did not exist, and instead the three Perforator worms would spawn and attack at once.
• Previously, when any worm was killed, several smaller worms known as Perforator Mini would spawn.
• If the Boss Checklist Mod is installed, their unique despawn message will be "The Perforators search for more hosts to gorge themselves on."

Bestiary entries

• The Perforator Hive: "To tear and consume, taking for only themselves until there is nothing left– this was the primal instinct left behind by the gods which now form the Crimson. Their selfish desires coalesced into this hive, infested by ravenous worms whose sole desire is to devour."
• The Perforators: "A living embodiment of some of the worst this world has to offer, these parasites made full use of their hive. Using it to seek ever more to gorge themselves upon, they sought to grow even larger, that they may one day perhaps regain what they lost."
