"These machines are my finest scouts and agents, reborn in a form that gives them Sight unrivaled."

The Twins are Hardmode bosses that can be fought anywhere on the Surface at night.

While in Revengeance and Death Mode, the Twins are fought in phase 2 simultaneously, and get a third phase in which their attack patterns become more complex.

Spawn

The Twins can be summoned manually using a Mechanical Eye at night in any biome. They also have a 10% chance to spawn randomly at dusk once a Demon or Crimson Altar has been destroyed, as long as they have not been defeated in the current world. Their arrival is announced by the status message: "This is going to be a terrible night...".

Behavior

The Twins will spawn together, connected with a flesh tether. They will both attack the player simultaneously.

In Revengeance Mode

Phase 1

Spazmatism will alternate between staying horizontal with the player and quickly shooting Cursed Flame shots, and performing 8 quicker but shorter dashes towards the player. Retinazer will alternate between staying diagonally above the player and firing bursts of 3 purple lasers, and performing 3 longer but slower dashes towards the player.

Phase 2

Both twins will enter phase 2 upon reaching 70% health. If one of them is in phase 1 while the other is in phase 2, the one in phase 2 will take negligible damage. If gravity is reversed, both twins immediately transform into their second phases. While gravity is reversed, Retinazer's lasers fire faster and more frequently.

In this phase, Spazmatism will alternate between slowly chasing the player while breathing Shadowflame and performing 5 long and fast dashes towards the player. Retinazer will continuously shoot red lasers at the player, with the pattern of hovering above the player and slowly firing 3 shots followed by hovering to the side of the player and firing a quick burst of 8 shots.

Phase 3

The Twins will enter phase 3 when they reach 25% health, or the other twin is defeated.

In this phase, Spazmatism will start to use a new attack where it will hover beneath the player and shoot semi-homing shadowflame fireballs. Its flamethrower attack is used for less time. Its dashes become longer and faster, and it will move faster while breathing shadowflames. Retinazer will start to perform a new attack, where it will do two long dashes after shooting lasers, firing several homing darts during the first dash.

If Retinazer is defeated first, Spazmatism will stop breathing shadowflames and begin performing a longer set of charge attacks, where it will perform 4 regular charges and a final one which will travel further. When dashing, contact damage is increased by 10%. If Spazmatism is defeated first, Retinazer will begin shooting lasers much more quickly and its dash attack will now consist of four dashes, releasing homing darts on the first and last dash.

If it becomes day, the Twins will enrage, becoming more aggressive, charging further and firing projectiles more often. Their projectiles also have increased velocity when enraged. Spazmatism's flamethrower will also have a longer range.

In Death Mode

• As their health gets lower, the speed and acceleration of the twins increases, and their attack delay is reduced.

During the Boss Rush

• Max health increased to 2,750,000 / 4,125,000 / 5,268,750
• Sets the time to 7:30pm

Aftermath

• If the Early Hardmode Progression Rework option is enabled, new ores will be generated in the Underground and Cavern layers:
  • If The Twins are the first mechanical bosses to be defeated, Mythril and Orichalcum Ore will be generated.
  • If The Twins are the second mechanical bosses to be defeated, Adamantite and Titanium Ore will be generated.
  • If The Twins are the third mechanical bosses to be defeated, Hallowed Ore will be generated in the Underground Hallow biome.
• The Bandit will begin selling the Momentum Capacitor if The Destroyer and Skeletron Prime have also been defeated.
• The Drunk Princess will begin selling Vodka, Screwdriver and White Wine if The Destroyer and Skeletron Prime have also been defeated.
• The Archmage will begin selling the Arctic Bear Paw, Frosty Flare, Cryophobia and Cryogenic Staff if The Destroyer and Skeletron Prime have also been defeated.

Tips

For more elaborate strategies on defeating The Twins, including weapon and arena recommendations, see Guide:The Twins strategies.

• Be sure to damage The Twins at a somewhat equal rate prior to phase 2, to make sure that neither become invulnerable.
• Try not to have both Twins in phase 3 at the same time, as they will become much more difficult to dodge.
• While it is easier to leave Retinazer alone towards the end of the fight, it is very difficult to do so due to its lower health. More often than not, you will end up with both Twins in phase 3.
• Be aware of Retinazer's firing patterns in phase 2, it will shoot 3 lasers at a low firing rate followed by a fast burst. Time your movement so you have enough wing time to avoid the burst by flying diagonally up and away from The Twins to keep yourself safe from Spazmatism.
