Sailor Piece is a popular Roblox experience inspired by the famous anime series One Piece. Here, you can explore islands, fight enemies and bosses, and unlock new weapons while collecting fruits and gear to increase your power. Among its many unlockables, the Cosmic Being fighting style stands out as a desirable one.
Cosmic Being is best known for its overwhelming damage output and the durability it provides, which makes it a top-tier choice for end-game builds. So, if you want to get your hands on it, here’s a complete guide on Cosmic Being in Sailor Piece.
How to Get Cosmic Being in Sailor Piece

The Sea 2 update in Sailor Piece has added new islands, gameplay mechanics, weapons, and powerful fighting styles, like Cosmic Being. This fighting style draws inspiration from Garou in One-Punch Man, which explains its aggressive combat style. However, to unlock it, you will need to gain access to Sea 2 first.
Once you have done that, make your way to Punch Island. At the center of the island, you will find the Cosmic Being Boss, which you will need to defeat repeatedly, either for a direct drop or to farm required materials. However, the latter method is far more reliable, as you do not need to depend on RNG to obtain the fighting style as a drop.
So, if you want to unlock Cosmic Being by farming materials, go to the trainer NPC positioned on top of a building with a distinct pink rooftop, located close to the Set Spawn crystal. This NPC allows you to unlock the fighting style if you have all the necessary items. Below, we’ve mentioned all the materials required to unlock Cosmic Being and how to get them.
| Item / Material | How to Obtain |
|---|---|
| Cosmic Essence (12x) | Dropped by the Cosmic Being Boss (moderate drop rate) |
| Star Mark (8x) | Dropped by the Cosmic Being Boss (uncommon drop) |
| Galaxy Shard (5x) | Dropped by the Cosmic Being Boss (rare drop) |
| Monster Pulse (2x) | Dropped by the Cosmic Being Boss (very rare drop) |
| Cosmic Being Title | Dropped by the Cosmic Being Boss (extremely rare, includes pity system) |
Cosmic Being Boss in Sailor Piece – Location & Details

The Cosmic Being Boss plays a central role in unlocking the Cosmic Being fighting style, as both the direct drop and required materials come from defeating him. To challenge this boss, you will need to travel to Punch Island in Sea 2 and head straight to the middle of the island, where he appears. However, the boss spawns roughly every 30 minutes based on server time.
Moreover, the Cosmic Being Boss comes with an enormous health pool of around 500 billion HP, making fights long and demanding. What makes things even more challenging is that every time its health drops by 25%, it activates a random passive ability. Below, we’ve listed all the possible passives the boss can trigger
- Harden – Increases its damage resistance by an additional 10%, stacking with its already high base damage reduction.
- Rage – Boosts its damage output by 25%, making its attacks much more dangerous.
- Accelerate – Enhances movement speed by 25%, allowing it to chase and reposition faster.
- Regenerate – Restores 10% of its lost health, extending the fight further.
How to Unlock Cosmic Being F Move in Sailor Piece
Once you have successfully obtained the Cosmic Being fighting style in Sailor Piece, you can unlock the F Move to make it even more powerful. Head over to the left side of Punch Island, where you will find the Cosmic Being Master NPC.
Interact with him to start a special questline that unlocks the F move, and also provides a noticeable damage boost. Below, we’ve mentioned all the requirements that you must meet to unlock the F Move.
- Defeat the Cosmic Being Boss a total of 15 times
- Clear Infinite Tower Floor 90 or higher on 5 separate runs
- Acquire the Astal Bloodline
After finishing all of these objectives, you will unlock the Cosmic Being F move. In addition to gaining access to this powerful ability, the fighting style will also receive a 30% increase in overall damage, making it even more effective for clearing endgame content.
