I have created Master Mode guides for nearly every boss up to this point, and I can honestly say that this is one of the easiest mechanical boss fights once you use the right strategy.
Normally, The Twins are considered one of the harder mechanical bosses because you are fighting two enemies at the same time. Each eye behaves differently and becomes more aggressive as the fight progresses. This can make the encounter feel chaotic, especially for players who are not fully prepared.
However, by using a very simple strategy that focuses on mobility, the fight becomes dramatically easier. With the right setup, you can avoid most of their attacks and defeat them quickly without needing an elaborate boss arena.
The key to this strategy is using a powerful mount that allows you to control the fight by staying out of the bosses’ range.
Necessary Items
The most important item for this strategy is the Black Spot, which is the pirate ship mount dropped by the Flying Dutchman during the Pirate Invasion event.
This mount is incredibly strong because it provides extremely fast movement along with infinite flight. Mobility is one of the biggest advantages you can have during mechanical boss fights, and the Black Spot allows you to stay far enough away that many attacks will simply miss you.
I used this mount in my Destroyer Master Mode guide as well, but against The Twins it almost feels overpowered. The speed of the ship lets you outrun most of their projectiles and maintain constant distance from both bosses.
If you do not already have the Black Spot, it is definitely worth farming Flying Dutchman ships during the Pirate Invasion until it drops. Even if it takes several attempts, the mount is extremely valuable for the rest of your Master Mode playthrough. I will also be using this same mount in my upcoming Skeletron Prime guide because of how effective it is.
Once you have the mount, the rest of your gear becomes much less important.
You can use a variety of weapons successfully since the strategy relies more on positioning than raw damage output. During my run I used the Daedalus Stormbow, which still performs well when paired with Holy Arrows. However, other ranged weapons work just as well. Weapons such as the Uzi or an Adamantite or Titanium repeater can produce similar results.
Armor should be either Adamantite or Titanium, depending on which ores your world generated in Hardmode. Make sure you craft the correct helmet for your class so you receive the proper damage bonuses.
For example:
-
Ranged helmets work best if you are using bows or guns
-
Magic helmets are ideal for magic builds
Melee builds are generally not recommended for this fight in Master Mode because they require you to stay close to the bosses. Staying at range is much safer and works much better with the strategy used here.
Helpful Buffs
Buff potions are not absolutely required for this method, but they can make the fight quicker and safer.
Some of the most helpful potions include:
-
Ironskin Potion for extra defense
-
Archery Potion for improved arrow damage
-
Regeneration Potion to increase health recovery
-
Swiftness Potion for additional movement speed
Food buffs that increase health regeneration can also help slightly.
When I fought The Twins, I used more buffs than I probably needed just to make the fight even easier. Once you get comfortable with the strategy, you may find that potions are not necessary at all.
The Twins Strategy
Normally when writing Master Mode boss guides, I recommend building a full boss arena with long platforms, campfires, heart lanterns, and other regeneration items.
With this strategy, however, an arena is not really necessary.
Because the Black Spot mount allows you to fly indefinitely at high speed, you will spend most of the fight moving through the air rather than standing on platforms.
To begin the fight, summon The Twins using the Mechanical Eye during nighttime. As soon as they spawn, mount the Black Spot and begin flying in one direction across the map.
The main goal is to stay far enough away that their attacks cannot consistently hit you. The pirate ship mount moves so quickly that The Twins will often struggle to keep up. Many of their projectiles will simply fall behind you before they even reach your character.
One thing you do need to watch out for is flying too far ahead. If you create too much distance between yourself and the bosses, they can temporarily disengage or even despawn. Try to stay at a distance where you can still attack them while maintaining enough space to avoid their attacks.
During the fight, focus on defeating one of the Twins at a time instead of damaging both equally. Most players prefer to eliminate Spazmatism first since its second phase flamethrower attack can become very dangerous.
Once the first eye is defeated, the fight becomes much easier since you only need to focus on the remaining one. Continue flying in the same direction while firing your weapon and adjusting your movement slightly when necessary to avoid lasers or fireballs.
Because of the mount’s speed, many attacks will miss entirely, and the boss will slowly lose health as you continue attacking.
Farming The Twins
Another advantage of this strategy is how quickly the fight can be completed. When using strong ranged weapons and consistent damage output, the battle can end within just a few minutes.
Because of this, it is actually possible to defeat The Twins multiple times during the same night cycle. If you have several Mechanical Eyes prepared, you can summon them repeatedly and farm their drops efficiently.
This is extremely helpful for collecting important Hardmode materials such as Souls of Sight and Hallowed Bars. Farming these items quickly allows you to craft stronger gear and progress through Hardmode much faster.
It also gives you a reliable way to collect the Master Mode relic if you are trying to complete a full boss collection.
Final Thoughts
Although The Twins can feel intimidating at first, the Black Spot strategy makes the fight surprisingly manageable.
By focusing on mobility instead of building large arenas or relying on extremely powerful weapons, you can stay out of the bosses’ attack range and defeat them safely from a distance.
With a little practice, this method allows you to beat The Twins quickly and consistently, even in Master Mode. Once you get comfortable with the strategy, farming the boss for materials becomes incredibly easy and can significantly speed up your progression through Hardmode.
