The Sea Beast is a mini-boss that can spawn in the Second Sea and Third Sea when sailing. Sea Beasts come in a variety of colors, including green, brown, red, and blue. The total health of a given Sea Beast is determined by the number of players near its spawn location.
Quick Answers

What makes the Sea Beast unique compared to other aggressive NPCs?
Behavior[]
Sea Beasts, unlike most aggressive NPCs, are only vulnerable to special moves and are immune to most M1 attacks. There are some exceptions to these such as:
- Explosive Guns
- Blade
- Bomb
- Eagle
- Rubber
- Phoenix
- Pain
- Gravity (Any type and stages)
- Mammoth (transformed)
- T-Rex
- Dough
- Gas (Base and Transformed)
- Tiger (Transformed and Blazing Form)
- Yeti
- Kitsune (Base and Full Form)
- Dragon (Base and Full Form)
Some non-M1 special moves also will not deal any damage to Sea Beasts, most notably single-target moves (e.g., Shadow's [Z] move).
Spawning[]
Natural spawning[]
- When riding around a Boat in the Second Sea, there is a small chance for a Sea Beast to appear in front of the sailor's Boat. It should be noted that the player does not have to actively ride the Boat around for the Sea Beast to appear and can simply remain still and wait. Either way, it can take a bit to find a Sea Beast in Second Sea.
- The same can occur with a slightly higher chance in the Third Sea at Sea Danger Level 1-6, though in this case, multiple Sea Beasts might emerge; this is not to be mistaken for the Rumbling Waters event.
- In the Third Sea, there's a small chance for Rumbling Waters to occur when riding a Boat at Sea Danger Level 1-6. During this Sea Event, multiple Sea Beasts will emerge from the sea and heavy rain will ensue. The way to tell the difference is that during a Rumbling Waters, a text will appear at the top saying <Rumbling Waters>.
Summoning & Other[]
Note: Sea Beasts spawned via the following ways do not drop anything.
- The Tide Keeper may summon a Sea Beast with 20k HP when fighting a player.
- When a player earns 10 million bounty/honor, they can summon a Sea Beast. The summoned Sea Beast has HP varying depending on the player's level. More can be found in the Summon Sea Beast page.
- A Sea Beast will appear during the Trial of Water (Shark V4's trial).
- Sea Beasts will be encountered during Phoenix Raids.

Notes/Tips[]
- It is heavily recommended to use Boats with high health (e.g., Grand Brigade).
- Miracle is also good because of its small hitbox but other sea events may damage the boat and potentially sink it.
- Race V4 is extremely useful for Sea Beasts, as the player gets max stats on the entirety of their moveset, which is especially good when the user has access and mastery to all the four main ways to deal damage, including Blox Fruit, sword, fighting style, and gun. This allows the user to spam all of the attacks in their moveset therefore dealing extremely high amounts of damage.
- The Shark race is specifically useful when fighting Sea Beasts, especially Shark V2 and above due to its immunity to water damage. Water Body and Leviathan Armor (Awakened Race) also increase survivability when fighting Sea Beasts, especially when fighting multiple at a time.
- Sanguine Art has long-ranged and high-damage moves that are useful against Sea Beasts. Death Step, and Electric Claw are great alternatives to this, as their moves now deal damage to Sea Beasts as of Update 20.
- Ice and awakened Magma are handy due to their passive ability to walk on water.
- People could unawaken Magma's [F] move because it does consistent damage unlike the Awakened version. (This is only recommended if the Player has all the other moves awakened or has Shark V2 and above because the Sea Beast can "push" the Player underwater.
- Awakened Buddha is also fairly useful as its transformed mode hitbox is above the water.
- Gas is similar to Buddha as the transform M1 is above the water. But as of the damaging capabilities, Magma or Gas is currently the best because as listed below, all of the moves, including the M1 (and not just the fifth click, all of the clicks can hit the Sea Beast unlike other fruits that have Similar M1s).
- Gas, Yeti, Kitsune and Tiger are really good fruits for Sea Beasts, because of its M1s. (all five clicks work)
- Blizzard is also considered to be one of best fruits for Sea Beast because of its high AoE moves, and therefore could considered better than Awakened Magma, due to its [F] Tornado Flight move.
- Leopard or Mammoth is particularly recommended for hunting Sea Beasts, as all of its moves can damage them, even transformed leopards M1s.
- Blizzard or Awakened Dough is also an amazing choice as all moves including [F] and Tap (only awakened Dough) can damage them.
- Awakened Phoenix is a good choice as the flames left behind by the [Z] move can damage it, and almost all transformation moves (including M1) can hit it. If the user is low, they can use Blue Flames near the Sea Beast, which does great damage to it while healing the user.
- Energy is usually not an issue unless the player heals very often. To prevent energy loss, Cyborg can help as its V2 passive allows it to recover energy while taking damage.
- Lightning]] is particularly good for sea beast hunting because of its [X] move's projectiles all hitting it, doing a lot of damage, and can be extended by using [Z] Lightning Orb.
- There are 3 most recommended swords for Sea Beasts:
- Shark Anchor is recommended and the most effective for hunting Sea Beasts because of its ability to be easily obtained, Z attack damage with great range, more important than the increased [X] damage when dealing damage to a Sea Beast.
- Saber is recommended for first-time sword users who are hunting. However, it is important to note that Z move's damage has been significantly reduced and has less mobility.
- Cursed Dual Katana is also recommended for hunting because of its high mobility. However, it is difficult to obtain and its hitbox is difficult to target, sometimes bouncing back.
- The Leviathan Shield is ideal for killing Sea Beasts due to its 90% protection against Sea damage and 30% defense against Sea Events, which includes Sea Beasts. It also provides the player with a +1000 Health boost. However, players can also utilize Shark race's V2 passive, as it grants complete Sea damage immunity.
- Leviathan Crown or Shark Tooth Necklace can also be used to deal more damage to Sea Events, which includes Sea Beasts; however, if the player has not unlocked these, they can use various other Accessories that boost damage.
- It is not recommended to use Buddha unless the player can do high damage with their weapon/fighting style moves because that is basically all that the player has, and they cannot use M1s which Buddha heavily relies on.
- Although, as a counterpoint, Buddha fully awakened when paired with stats can be extremely powerful. This is because when fully awakened, the AoE and damage are significantly increased when compared to its unawakened form, especially Buddha [V] awakened. Putting stat points on Buddha can make it powerful aside from its M1 spam. The user can add to this by pairing awakened Buddha with Dragon Talon, Sharkman Karate, or Sanguine Art for heavy damage on their fighting style. Pairing all this along with Race V4 gives the user a higher chance of survival.
- Sea Beasts/Rumbling Waters can serve as an effective way of farming money in Third Sea due to the massive amount of money they drop and how common they are the higher your sea danger level is. With 2x money, each Rumbling Waters gives around $1,500,000.
Strategies[]
- Magma, Pain, Gas, Kitsune, Yeti, Mammoth, and Tiger are currently the best fruits for Sea Beast hunting as of Update 28 because all of the moves, including Gas', Kitsune's, and Tiger’s M1s can hit the sea beasts. (Magma deals the highest damage in the shortest time and Mammoth's Transformed [F] (Stampede) can deal large amounts of damage in a slightly longer time than Magma.)
- The easiest way to kill Sea Beast/Rumbling Waters is to use Magma to damage each Sea Beast or to use Mammoth F move while transformed. The player does not even need to be near the Sea Beast to do Damage. This makes even Rumbling Waters extremely easy to solo.
- With the addition of the reworked Bomb fruit, Rumbling waters are now even easier to solo by spamming Bomb's C move which deals absurd amounts of damage to Rumbling Waters.
- It is recommended to stay below Sea Danger Level 3, as the Terrorshark and other factors may easily destroy the players boat. (Only in Third Sea)
- The player should not have their Instinct on at all times and only use it to dodge Water Beams, as certain attacks can drain/break their Instinct, preventing the player from dodging incoming beams.
- The player should try to stay high in the air so that Water Beam does not push the player underwater and kill them.
- The player should learn to predict when the Sea Beast is going to exert a move. If they are far away and the Sea Beast suddenly turns their way and recoils, or if they emit a certain charging sound effect, they are likely going to use the Water Beam. This can be easily read and countered by dodging with Instinct or by dodging using a dash move (not recommended as the timing is extremely tight). The player should turn off Instinct immediately after dodging the beam (unless they hear another beam incoming) to prevent other attacks from disabling it.
- The Sea Beast usually uses Deadly Shower at closer range. Each bullet does minuscule damage but can be fatal if all of them hit. It should not pose a threat due to the large space between projectiles, making it easier to dodge the projectiles, unless the player is a Buddha user, or they are near a surface for the projectiles to explode. The attack has a long duration, and the Sea Beast is stuck in place while performing the attack, making it vulnerable.
- If the Sea Beast suddenly stops moving and raises its head, it's recommended that the player turns off their Instinct as this signifies the Sea Beast is about to roar, breaking Instinct and rendering the player vulnerable.
- When the player hears/notices a Water Beam incoming, they should stop holding a move and activate Instinct immediately. It is preferable to dodge the beam than to deal more damage and risk losing health in the middle of the fight.
- When retreating to heal, the player should not go too far away from the Sea Beast if they do not have any Instinct dodges. It can still use Water Beam even if the player is far away. Meanwhile, being closer the Sea Beast will trigger it to use Deadly Shower and Roar, which can easily be avoided or tanked.
- Using large Area of Effect moves such as Blizzard's V move or Dough's C move in the center of a group of Sea Beasts can damage multiple of them. The player can use this to their advantage to prevent them from de-spawning and maximize damage.
- Using the F moves of some certain fruits such as Blizzard, Dough, awakened Magma or Mammoth is a good way to deal extra damage when all of the player's moves are on cooldown.
- When fighting multiple Sea Beasts, the player should focus on one Sea Beast at a time instead of fighting all the Sea Beasts in the group at once. The player can try to use Blizzard if they want to fight every sea beast.
- Occasionally using long-ranged moves on other Sea Beasts is a good tactic to prevent them from despawning.

Trivia[]
- The revamp of Sea Beast was created by @SIRL_ (Twitter), a Brazilian who remade Blox Fruits models in Update 17.3.
- In the previous updates, around Update 17.1 and earlier, Sea Beast was considered a boss because Sea Events had not been released yet, it was the only enemy in the Sea Event.
- The theme that plays when the player encounter a Sea Beast is called "Haunted Halls". The same theme also plays when the player is at the Dark Arena, Treasure Island, an inactive Prehistoric Island or triggering the Rumbling Waters.
- Multiple Sea Beasts can spawn in the Second Sea, but they are not a Rumbling Waters because there is no rain, and the text indicating that it is one does not show up. (Instead, "<Sea Beast>" will show up.)
- Sea Beasts let out roars when spawned. The player can use this to find Sea Beasts efficiently. However, the player should keep in mind that Awakened Magma's [F] move has a similar sound effect, but a little bit shorter duration and higher pitched. The similar sounds may lead to confusion.
- Sea Beasts will disappear once the player is out of range for too long (around 30 seconds), or automatically after 15 minutes if not killed.
- Players were able to walk on Sea Beasts' heads before the remodel of their design.
- "SB" is an abbreviation of Sea Beast (such as "sb hunt" for when people want to hunt Sea Beasts).
- Multiple people can get a Fist of Darkness from the same Sea Beast, as long as they do enough damage.
- Sea Beasts cannot be seen with Instinct, although their moves can be dodged with it.
- Although able to receive damage from Sanguine Art's [Z] Move, the player will not attach or steal any health, which damages the Sea Beast thanks to the bats.
- Killing a Sea Beast is required to obtain Shark V3.
- There is currently a bug for some people that after killing 25 Sea Beasts you will not receive the title #114 "The Beast".
