Spawn Condition[edit | edit source]
Duke Fishron can be spawned by using yourwith as Bait.
It must then be defeated within the Ocean.
The Fight[edit | edit source]
Duke Fishron has two phases, with one additional phase in Expert Mode .
First Phase[edit | edit source]
Duke Fishron will attack in three different ways during the first phase. The first thing Fishron will do is begin his charging flurry. He will charge towards the player exactly five times, with a short pause between each charge.
After each charge, he will execute one of the two Projectile attacks:
- The First attack fires around 20 ;
- The Second attack will create two small Bubbles on either side of where he is located that will each generate a Sharknado. The Sharknadoes are tall and do damage, but they also fire towards the player.
Second Phase[edit | edit source]
When Duke Fishron falls below 25,000 health, he will stay stationary for a second, then his eyes will glow as he enters his second stage. His damage and speed increase significantly. However, his defense drops to 40.
His charge flurry only has 3 charges, but they are a bit faster than before. He still has two kinds of projectile attacks, but their patterns change:
- The Detonating Bubble attack now causes him to move around in a circle, dropping the bubbles in a circle around his original location. This spreads out the bubbles, making it more difficult to hit them all.
- His Sharknado attack upgrades to summon a Cthulhunado. He will fire a special bubble at you that is quite fast. When it hits you, it will spawn a Cthulhunado, a very tall tornado that does lots of damage and fires large quantities of Sharkrons. It also lasts much longer.
Note that, after the battle is over, care should still be taken. If he has launched a Cthulhunado, it may still fire Sharkrons. He may also have died in the Cthulhunado, so don't charge into it to collect his drops until it dissipates.
Duke Fishron's charging attack is his primary attack, and one of the most difficult to dodge.
The key to dodging it is to try to move perpendicularly to where he is aimed, right before he makes his charge. For example, if you are horizontal with him when he is about to charge, you need to quickly up (or down, if you're already flying). If he is right above/below you, then you need to quickly move left or right.
One important element of the Sharknado attack is that they will spawn in the location where Duke Fishron was when he fired the attack. And they will despawn almost exactly when he is ready to drop another pair of Sharknadoes.
As long as the player keeps in mind what attack Duke Fishron will do next, the player can put him in a position that makes it hard for the player to hit the Sharknadoes themselves. For example, during the charging flurry before the Sharknado attack, the player can move towards the edge of the screen, horizontally. That way, the player can run the other way knowing that they will not encounter Sharkrons from that direction. This also means that attacks towards Duke Fishron will also be towards the direction of incoming Sharkrons.
Also, note that Duke Fishron's first attack will always be bubbles.
Sharknadoes are quite tall; getting over them will require fastor a .
The upgraded Sharknado attack is a bit more difficult to deal with. It's taller, and it does more damage than the original, plus it fires more Sharkrons.
However, there is one thing that makes it a bit easier to deal with: the Cthulhunado will spawn in the location where you were when the bubble hit you. This gives you a bit more control over where the tornado spawns, so you have more of a chance (if you are fast) to make sure it doesn't spawn in an inconvenient place. You likely do not have the speed to outrun the attack, but you can help get it out of the way.
The downside of course is that, once the bubble hits you, you need to quickly move, lest it spawn on top of you.
Another important factor to note is that by no means necessary should you attempt to cross a Cthulhunado. They deal about 100 damage, which will turn the fight in Duke Fishron's favor. Always use Wings to fly over them. Alternatively, use the Rod of Discord to teleport to the other side.
Expert Mode[edit | edit source]
When Duke Fishron drops below 9000 health, he will transform again and the background will notably darken, while making himself invisible except for his glowing eyes.
He will only be able to use his charge attacks in this stage, but he will gain the ability to teleport behind the player before attacking. The charges will come in a set pattern: After teleporting, he will successively charge once, then twice, and finally three times before the pattern resets.
While his contact damage is reduced, the high speed of his charges can cause you to get hit many times in a quick succession. Pay attention to his attack pattern, and make sure to not stand still during the fight. You should also try to get away from any Cthulhunadoes left from the second stage.
Due to the frequency of his teleportation, you may prefer homing or high velocity weapons during this stage.

Terrain Preparation[edit | edit source]
The Arena must be located in the Ocean, unless you're very confident that you can beat an enraged Fishron, which is usually not recommended.
- Make an arena out of . It should stretch at least across the ocean. Make it 3-5 platforms high; each row should be at least 20 blocks away from each other. Leave a gap at either side for maneuver, however.
- The Arena must be very tall: the Tornadoes are very tall, and thus, it requires significant amount of flight time to go to the other side of it.
Gearing up[edit | edit source]
By this point, you should have 500 Health. If not, it's recommended you use as many Mechanical Bosses in order to spawn Life Fruits.as possible. You need to beat at least one of the

Accessories[edit | edit source]
- are a must-have for the fight. The can make them significantly faster, making it easier to get over the Cthulhunadoes and dodging his attacks while flying.
- The Master Ninja Gear, Shield of Cthulhu, or Tabi are incredibly useful for dodging its attacks with their dashing capabilities.
- Accessories that increase damage are a must have for ending the battle sooner. The best choices include the Celestial Shell or Stone, Destroyer Emblem, Mechanical Glove, and Sniper Scope.
- Cross Necklace or Star Veil is recommended as the boss speed might cause several heavy hits on characters should the boss catch the player. The Sharknados may also flank the player hitting them consecutively especially on Duke Fishron's second phase.
- Characters with Spectre Armor should consider using Magic Cuffs or Celestial Cuffs, as the damage dealt by Duke Fishron's attacks will often times completely restore their MP, allowing them to attack constantly while restoring HP. Care should be taken as the boss' high attack can make quick work of reckless players.
- If you are using The Eye of Cthulhu or another yoyo, use a Yoyo Bag.
- Charm of Myths will both allow for increased regen and reduced time for the Potion Sickness debuff.
- The mount is a good replacement for Wings and can be better as it provides infinite air time. Unlike Wings, however, it's much slower and can't be used with a dash.
Potions and Buffs[edit | edit source]
As with any other Hardmode boss, it would be useful to prepare the following potions:
- Inferno Potion is highly recommended as it will destroy the Detonating Bubbles Fishron spawns before they reach the player.
- Regeneration Potion and Ironskin Potion to survive. Two of each will last enough.
- Endurance and Lifeforce potions for even greater survivability.
- Any food item that can provide the Well Fed buff is very welcome.
- Swiftness Potion helps you a lot to evade the Duke and its attacks.
- Wrath and/or Rage Potions for a boost in damage output.
- Magic Power and Mana Regeneration potions are a must for Magic users.
- If a player has no arena, they can just use Water Walking Potions.
- Gravitation Potions can free up an accessory slot, but it's recommended to use Featherfall Potions with them.
- Melee characters should use the Tipsy debuff and the Flask of Ichor if available.
- If you are facing him at night, a Shine Potion, Night Owl Potion, and Hunter Potion will help a lot so that you don't have to worry about visibility.
More In-Depth Strategies[edit | edit source]
Minecart Strategy[edit | edit source]
This strategy differs from others in that it doesn't use skybridge, replacing it with looped minecart track above the ocean, so the player won't have to deal with his enraged behavior. It does, however, need some more work than other ones, especially when building the arena.
Materials[edit | edit source]
- 600-1200 normal minecart tracks for building loop + 2 booster tracks
- Any kind of hammer
Arena Preparation[edit | edit source]
The essence is to make looped minecart track approx. 60 tiles above Ocean itself. It should consist of at least 600 tiles; while shape is pretty loose, it should have at least two places in which player drastically changes altitude, as well as at least 100 tiles long flats.
One should also make a "Starter" - a short molo with boosters, from which player will summon Duke Fishron and quickly escape to the loop.
It should be noted also that arena shouldn't exceed Ocean biome.
Execution[edit | edit source]
When everything's done, player should sit in a minecart on "Starter" and summon the Fishron. As soon as it's done, one should quickly go to loop (boosters will help). At this point, everything that remains is to shoot Fishron while maintaining speed on track, healing a/o replenishing mana when needed. Some tips:
- Use a homing weapon, especially if your arena is pretty large. Fishron will spend most time off-screen, and high speed will often change directions you're facing.
- Though stock minecart shouldn't be used, Mechanical Cart is not a good choice. Even though with it provides defense bonus, as well as speed to avoid Fishron's charges, it can easily outrun him causing Fishron to despawn, which is possible on larger arenas. Higher speed means also that you will more often run into Sharknados.
- Try to make arena consisting of approx. 800 tiles, but don't make it horizontally-long. If you do so, Fishron will frequently run into you, and Cthulunados in his second stage will quickly kill you as there won't be any way to dodge them.
Spike Strategy[edit | edit source]
This strategy exploits invincibility frames obtained with the Cross Necklace by standing on a Spike. The Spike will do very little damage to a player with high enough defense, while the Cross Necklace will make it so the player is invincible for most of the fight. This strategy doesn't work in 1.3 or higher.
Laser Machinegun Strategy[edit | edit source]
This strategy is pretty simple, although slow. It is also tried and tested in Terraria 1.4. You need the Laser Machinegun, the UFO Mount (Cosmic Car Keys), a Mana Flower, and a lot of Greater Mana Potions. If you have maximum mana (200), then about 60 potions should do. All it requires is equipping the Mana Flower, activating the UFO mount, and flying away from Duke Fishron, keeping the Laser Machinegun trained on him the whole time. This will put out a ton of DPS, and will kill him pretty quickly. Even if you accidentally enrage him, the UFO moves fast enough that the strategy will probably still work. However, this strategy, while self-proclaimed to be a good one, has not been tested in Expert mode.
Enraged Anti-Gravity Hook Strategy[edit | edit source]
When Enraged, Duke Fishron is much faster and does much more damage. But with this stategy, this strength can be turned into a weakness. What you must do is get an Anti-Gravity Hook and place one or more platforms in the air. After Duke Fishron becomes enraged, you use your Anti-Gravity Hook in the platform and start using it to spin in a circle. This makes it possible to dodge all attacks. Keep in mind that this strategy only works with enraged Duke Fishron, because in his enraged behavior he will do nothing but attempt to ram you. Then you use the hook on the platform, start spinning and dodge his charges.
