(The Twins)
"This is going to be a terrible night..."
The Twins are a Hardmode mechanical boss which is essentially a more difficult version of the Eye of Cthulhu. The Twins are two separate flying entities, Retinazer and Spazmatism, connected by a tendril, each with its own attack pattern and life count. Both must be killed in order to defeat the boss. Retinazer is usually the one which is defeated last because it is usually harder to hit thanks to its lasers.
The Twins can be summoned manually using a Mechanical Eye at night (7:30 PM to 4:30 AM). They also have a 10% chance to spawn randomly at dusk once a Demon or Crimson Altar has been destroyed, as long as The Twins have not yet been defeated at least once in the current world, with their arrival announced by the status message "This is going to be a terrible night...".
The Twins must be killed before dawn, otherwise they fly up and then despawn.
While The Twins are alive, the music Boss 2 will play.

Attacks
First phase
- The eyeball with the red iris, Retinazer, fires high velocity red lasers. It will usually attempt to remain diagonally above the player.
- The eyeball with the green iris, Spazmatism, fires medium velocity balls of Cursed Flame. It will usually attempt to remain horizontally in line with the player.
Both alternate between their signature ranged attacks and charging melee attack, much like the Eye of Cthulhu. Retinazer's charge attack has higher velocity but covers slightly less distance than Spazmatism's.
Second phase
Each eye has a second form, which each individually reaches upon its health dipping to 40%. Retinazer transforms at 8000 / 12000 HP while Spazmatism transforms at 9200 / 13800 HP.
- Retinazer becomes a mechanical eye with a laser cannon in its pupil, and only fires projectiles, ceasing its attempts to ram the player (or align with the player diagonally). It fires more rapidly and with higher damage, and periodically fires in quick barrages, but does significantly less damage. The barrages become more intense and frequent the more damage Retinazer takes, eventually occurring non-stop.
Retinazer will, however, align horizontally with the player when firing barrages, though not as tightly as first-phase Spazmatism does.
- Spazmatism becomes a mechanical mouth (similar to the Eye of Cthulhu) that chases the player, charging with greater speed and range, and periodically spews streams of Cursed Flames from its mouth in a manner similar to the Flamethrower. The flames can inflict the Cursed Inferno debuff and deal high damage. It no longer attempts to align horizontally with the player.
In Expert mode, Retinazer's laser firing becomes faster and charges cover more distance as its health depletes. Spazmatism's fireballs inflict Cursed Inferno for double the duration. Spazmatism also charges faster in its second form.
Notes
- When spawning randomly, The Twins spawn exactly 81 seconds after the status message has appeared. Being in a layer lower than the surface, or exiting the world (in singleplayer), will prevent The Twins from spawning randomly.
- On Old-gen console version, Windows Phone version, and Nintendo version, if The Twins are summoned with a Mechanical Eye on a night when The Twins are also spawning randomly, both pairs will appear and all four eyes will be connected.
- Both eyes can drop their respective trophy when killed, regardless of which is killed first. It is possible for both trophies to drop in one battle.
Tips
- Focus on defeating one eye completely first without doing too much damage to the other one. Battling The Twins while both are in their second form makes the battle much more difficult, especially in Expert mode
.- Spazmatism may be a better choice for defeating first, since its cursed flames are difficult to avoid without proper mobility equipment/buffs in its second form. Retinazer is less deadly, as it cannot inflict debuffs and will not charge in its second form, which helps the player get some distance if they are a ranger.
- A Cross Necklace helps during The Twins' second form, as players will take far less damage during barrage attacks.
- The Twins are only immune to Confused, so using a weapon that inflicts a debuff may be useful during the fight.
- A good arena for this boss is simply a long, flat plane. With Lightning Boots and a ranged weapon, the player can continually outrun The Twins' attacks while firing back at them.
- The Sharanga
is an excellent weapon against The Twins if it is fired as the player runs away. - A Daedalus Stormbow with Holy Arrows can be a great tactic, as it can deal massive amounts of damage while staying out of range of many of The Twins' attacks.
- The Shadowflame Knife can be great for melee players, as it does not require any ammo or mana, and can hit both eyes if aimed correctly.
- Retinazer's second form can not attack the player if he/she is hiding in a box. Defeating Spazmatism then causing Retinazer to reach its second form can become an almost guaranteed win if this strategy is used.
- A gravitation potion can be an excellent method of keeping distance from the twins allowing them to be attacked freely.
Trivia
- Retinazer's name is a portmanteau of retina, a part of the eye, and laser. Spazmatism's name is a portmanteau of spasm, meaning to twitch uncontrollably, and astigmatism, an eye disorder.
- Unlike Spazmatism, Retinazer’s second form has no visible bolts the left side.
- The Twins seem to have complete heterochromia iridum (two different eye colors).
- In its second form, Spazmatism's fire stream attack functions almost identically to the Flamethrower weapon, with similar range and damage, but inflicting the Cursed Inferno debuff instead of On Fire!.
- The Twins are the only boss with two trophies, and the only mechanical boss with phases.
- Despite inflicting it, Spazmatism is not immune to Cursed Inferno.
- The Twins are one of three bosses with a corresponding minion (Optic Staff), the others being the Martian Saucer
(Xeno Staff) and Duke Fishron (Tempest Staff). - In Master mode, The Black Spot mount travels faster than The Twins, allowing the player to run away and fire backwards for the entirety of the fight, thus making it fairly straightforward.
- – According to the official game lore, The Twins were one of the three mechanical recreations of Cthulhu's missing organs. They are a recreation of Cthulhu's eyes.
