How to Defeat Pre-Mech Duke Fishron

Pre-Mech Duke Fishron has multiple attack patterns for 3 different stages. Here’s what you should do against them:

First Stage

Immediately after the stage starts, you will want to move around the arena slowly. At this stage, the boss performs one simple charge attack towards you. To avoid the boss, keep jumping on and off to dodge the boss’ attacks and maintain a distance.

When hitting the player in Expert Mode or Master Mode, Duke Fishron has a 33% chance to give you a Bleeding Effect. You do not want this to happen unless you bring the Adhesive Bandage to help you remove the effects. These can be found by defeating Werewolves and Angler Fish.

After a while, the boss will change its attacks. In addition to its charge attacks, it will start shooting bubbles and spawning tornadoes and sharks to make it more difficult for you. Duke Fishron will start summoning liquid blobs that fall down on impact with blocks.

They then spawn Sharknadoes and several Sharkrons (small shark monsters that will charge at you). These Sharkrons have limited flight range, are destroyed on impact with blocks and can be eliminated by you. To deal with this, simply maintain a distance and slowly attack all the monsters to create some space for you to continue doing damage to the boss.

The Duke Fishron also performs another special attack. The boss blows roughly 10-20 bubbles from his mouth that follow the player at moderate speed, exploding and dealing damage on contact. The bubbles can be destroyed by any attack or projectile.

The bubble attacks can be difficult to dodge since the boss release them at big numbers. Your best option is to maintain a distance with the boss and break the bubbles to avoid damage.

Second Stage

You will see more tornado attacks in the Second Stage when the boss’ health reaches 50%. His skin becomes a darker green and his eyes will start glowing. His damage and speed increase significantly, but his defense is reduced to 40.

For the tornado attack, the boss will shoot a homing projectile at you, on contact it will spawn a tornado. Keep it in mind that if you stand on one of the platforms when the tornado spawns, you will take 300 damage. Your best option is to always keep yourself in the air for as long as possible.

Third Stage

In the last stage, the boss fight gets more difficult. After reaching 15% health, the boss will transform again. This is when the background will be covered with pure darkness. As a result, Duke Fishron will become invisible, but his eyes still glow. Use this to your advantage and locate where the boss is.

While the boss is invisible, he will charge 3 times at you. Here is the pattern for 3 attacks, he will charge once, then teleport behind you. In order to deal with this, always predict behind your back. Pay attention to each time he teleports and jump to dodge in between each attack intervals.
