Getting the Cosmic Being in Sailor Piece takes some patience, but once you understand how it works, farming it becomes a lot easier. This guide covers everything you need to know, from where the boss spawns to the best ways to farm it without wasting your time.
What is a Cosmic Being in Sailor Piece?
Cosmic Being is both a boss and a fighting style in Sailor Piece. It comes with its own boss, its own NPC trade route, and even a separate F move you can unlock later through the Cosmic Master questline. It is one of the more involved fighting styles to get, but it is worth the effort.
How to Get Cosmic Being in Sailor Piece
There are two main ways to unlock Cosmic Being in Sailor Piece. You can either trade the required materials to the Cosmic Being NPC on Punch Island, or you can unlock it directly by defeating a world boss. Both routes end up in the same place, so pick whichever works best for you.
1. Cosmic Being NPC Method
The first route involves gathering all the required materials and handing them over to the Cosmic Being NPC, who is found on top of a building on Punch Island in Sea 2. Once you have everything, just talk to the NPC and trade the bundle to unlock the style.

Here is everything you need to complete the NPC trade:
| Material | Amount Needed |
|---|---|
| Cosmic Being Title | 1 |
| Cosmic Essence | 12 |
| Star Mark | 8 |
| Galaxy Shard | 5 |
| Monster Pulse | 2 |
2. Defeating Cosmic Being Boss
The second route is to farm the Cosmic Being world boss itself. Defeating the boss can drop all the materials you need for the NPC trade, and it also has a direct unlock path attached to it. Here is the boss's info:

| Boss Detail | Info |
|---|---|
| Boss HP | 499,999,997,952 (about 500 billion HP) |
| Location | Punch Island, Sea 2 |
| Spawn Timer | 30 minutes after the boss is defeated |
| Drop Pool | Cosmic Essence, Star Mark, Galaxy Shard, Monster Pulse |
The boss does not respawn on a fixed server clock. The 30-minute timer starts after someone defeats it, so if you join a server and the boss was just killed, you are waiting the full 30 minutes. If it was killed a while ago, you might not have long to wait at all.
There is also no visible timer in the game, so you cannot see exactly when it is coming back. That is what makes server hopping useful.
Cosmic Being Boss Drop Rates in Sailor Piece
All four materials drop from the Cosmic Being boss. Here are the confirmed drop rates:
| Item | Drop Rate |
|---|---|
| Cosmic Essence | 6.53% |
| Star Mark | 3.26% |
| Galaxy Shard | 1.87% |
| Monster Pulse | 0.75% |
How to Farm the Cosmic Being Boss Efficiently
Since the boss has a 30-minute respawn after being defeated, farming it takes some planning. There are two methods most players use.
Method 1: Server Hopping
Server hopping is the faster method. You jump between servers and check if the Cosmic Being boss is already up or close to spawning. Since the 30-minute timer is based on when the boss was last killed, some servers will have it up right away when you join.
If you find a server where the boss is live, fight it, grab your drops, then move to the next server and check again. Done right, this lets you chain multiple kills in a short window without sitting around waiting.
Method 2: Stay in One Server
The second method is way more chill. You pick one server, and just stay there. Every 30 minutes, the boss will spawn, and you farm it when it shows up. In between spawns, you can work on other things in the game, so the time does not go to waste.
How to Unlock Cosmic Being F Move
Once you have Cosmic Being unlocked, you can take it a step further and unlock its F move through the Cosmic Master questline. This is a completely separate unlock from the base style, so you will need to put in extra work after you already have Cosmic Being.
The first confirmed step is Cosmic Being Mastery 1, which requires you to defeat the Cosmic Being world boss 15 times. That is a lot of boss kills, so if you are already farming for materials, it is smart to start counting your kills early and chip away at this requirement at the same time.
The rest of the Cosmic Master questline steps are not confirmed yet and will be added here once they are available in the game. For now, just focus on getting those 15 boss kills done first.
Cosmic Being in Sailor Piece is an awesome fighting style. Pick your farming method, head to Punch Island in Sea 2, and work through the boss runs at your own pace. For more codes, tips, and info about the game, check out our dedicated Sailor Piece wiki.
