Unlocking Cosmic Being in Sailor Piece is one of the heavier grinds in Sea 2—but it’s actually very straightforward once you understand the loop.
Step 1: Unlock Sea 2 (Mandatory)
Before anything else, you must have access to Sea 2 (C2).
Requirement:
- Reach Ascension 5
- Complete the Sea Traveler questline at World Island
Without this, you cannot reach the boss location.
Step 2: Go to Punch Island (C2)
- Travel to Punch Island in Sea 2
- This is where the Cosmic Being Boss spawns
This boss is the ONLY source of the required materials.
Step 3: Farm the Cosmic Being Boss
Here’s the key mechanic:
Every material required for Cosmic Being drops from the Cosmic Being Boss
Important Notes:
- Drop rates are very low (some below 1%)
- You will need many runs
- This is a pure RNG grind
Step 4: What You Need (General Idea)
While exact item names may vary, the pattern is always:
- Multiple rare boss drops
- Possibly a core item tied to the spec
- Materials only obtainable from this boss
You cannot shortcut this—boss farming is required.
Step 5: Farming Strategy (FASTEST METHOD)
If you want to unlock Cosmic Being quickly, follow this loop:
Efficient Loop:
- Go to Punch Island
- Kill Cosmic Being Boss
- Collect drops
- Server hop or wait respawn
- Repeat
Pro Tips
1. Server Hop Method
- Kill boss → leave server → join new server
- Faster than waiting for respawn
2. Farm With Others
- Boss has high HP (especially in C2 scaling)
- Faster kills = more runs = better RNG chances
3. Expect a Grind
- Some items are <1% drop rate
- Don’t expect quick unlock
4. Track Your Progress
- Keep count of materials
- Avoid overfarming after completion
How to Unlock Cosmic Being
Once you collect all required materials:
- Find the Cosmic Being NPC (usually near C2 areas)
- Turn in all items
- Unlock the fighting style
Cosmic Being is:
- A top-tier endgame fighting style
- Locked behind low drop-rate boss farming
- Worth it if you’re serious about progression
