Sea Serpents, also known as Sea Kings, are a type of Sea Beast that spawn in First Sea Rough Waters when a player ship is nearby. In order to properly spawn one, the player must be in the Rough Waters with any amount of bounty, although the chance scales with bounty.

They act as a sort of "mini-boss", which players can battle in order to gain prestigious reward that aid the user in both PvP and PvE.

Sea Serpents will only despawn after there are no players alive to target. This means that even if the player drowns by the Sea Beast, as long as there is another person nearby or if they can get back there and hit it again, it will not despawn.

The Minimum requirement to trade the Sea Serpents drops is lvl 300+

Moves[]

Sea Serpents have three attacks that they will cycle through in a pattern.

  • Roar: The Sea Beast will reel its head back before letting loose a loud roar, dealing AoE damage to nearby players. This move block-breaks and deals around 100 damage.
  • Beam: The Sea Beast will lower its head and quickly let out a beam that targets one player. This move is blockable.
  • Water Bomb: The Sea Beast will lower its head and charge up a Water Bomb for a few seconds. This move is identical to Fishman Karate's Water Bomb and deals a large amount of AoE damage. This move block-breaks.

Tips & Tactics[]

  • Farming Sea Serpents can be a task so the best way to do it is to go North West of Marine Base G-1 in the First Sea until you reach the patch of Rough Waters then spawn a boat guaranteeing a Sea Serpent to spawn as a protective measure for the Shrine.
  • The best Devil Fruits used to farm Sea Serpents are Pika, Magu, Hie, Zushi and Bomu (Bomu only on land), as their ultimates can deal a lot of damage. (For Bomu you can also spam mines) Demon Step also can be used to farm Sea Serpents (Using its Demon Axe Drop, Demon Blitz, and Demon Spectrum)
  • It's best to farm with a group, which the player can find on the GPO Discord. Even if they have any of the recommended fruit, it's still good to farm in group for faster rewards(Except if you are using Magu)
  • Tekkai is extremely useful for farming Sea Serpents, since the player will be able to block the roar that happens every 6–8 seconds, and the water bomb that deals a lot of damage.
  • The Sea Beast will only focus one person no matter what until they are knocked. This allows one person to lure the Sea Beast, whilst all other players attack its tail or its head.
  • Fruitless users can go into the water and barrage the part of the Sea Beast where it emerges from the water to deal massive damage.
  • Bari users can completely nullify all the Sea Beast's attacks for themselves with both Barrier wall and Barrier Sphere.
  • If the player leaves a Sea Beast's range, it will dive under the water for a few seconds, then proceed to pop out closer to the player. They can use this to their advantage by luring it into land.
  • (Pika users can lure sea beasts and krakens closer to land by using geppo once on top of water and aiming light flight towards the sky near land till the kraken or sea beast emerge in the sea to spawn near the player).

Trivia[]

  • The amount of XP earned is equivalent to the amount of damage the player deals to the Sea Beast. That means if they solo it they gain 10k+ XP.
  • The colour of the Slayer's Armour Set and Slayer's mask are based on the colour of the Sea Beast they dropped from.
  • Sea Beasts can be Blue, Green, Red, or Orange.
  • When the sea serpent spawn, it will roar then the sky begin to rain and darken (but not as dark as the Kraken)​
  • To even have a chance to get rewards, the player must do at least 500 damage to Sea Beast (5%) ​
  • Guns used to be good to farm Sea Beasts, but since Update 3.5 they only deal 50% damage to them.
