If you're farming Cosmic Being in Sailor Piece, the whole route is easier than it looks at first. The grind is long, but it's not complicated. Nearly everything you need comes from the Cosmic Being World Boss, so the real challenge is not figuring out where to go—it's reducing wasted time between spawns.

After running this route, the biggest difference-maker is clear: server hopping. If you stay in one server and wait for every spawn cycle, the grind drags badly. If you keep checking for active or nearly active boss servers, you can speed the process up a lot.

↖ How to Unlock Cosmic Being

To get Cosmic Being, go to Punch Island in SEA 2 and talk to the Cosmic Being Trainer NPC.

You need these materials:

The nice part is that all of these come from the same boss. That keeps the route simple even if it takes time.

↖ Why this grind feels slow

The boss is the bottleneck because it:

• Spawns every 30 minutes
• Has 4 phases
• Has around 500 billion HP
• Resets its spawn cycle only after the previous boss is defeated

This means your biggest enemy is usually downtime, not the boss itself.

↖ Fastest Farming Method

The best route is very straightforward.

1. Go to a server and check whether the Cosmic Being World Boss is up

2. If it is not close to spawning, switch servers

3. Farm the boss repeatedly until all materials are done

4. Return to the trainer NPC and buy Cosmic Being

From experience, this is where most players lose time. They focus too much on damage and not enough on finding good servers. Damage helps, but spawn efficiency saves more total time.

↖ Important bonus drops

While farming the boss, you can also get:

• Cosmic Being melee
• Cosmic Body

These are nice bonus drops, but I would not rely on them. It's better to farm as if you need the full material route, then treat lucky drops as a shortcut.

↖ Best Grind Checklist

Use this as a quick tracker while farming Sailor Piece Items:

Once you finish the list, go back to Punch Island and unlock the melee.

↖ Cosmic Being Mastery Guide

After unlocking the melee, talk to the Cosmic Being Master NPC. You need to complete 3 mastery quests.

↖ 1. Defeat 15 Cosmic Being World Bosses

This is the slowest part because of the spawn timer.

Best tip: keep server hopping.

If you wait in one server for all 15 kills, the mastery takes much longer than it should.

↖ 2. Reach Floor 90+ in Infinity Tower 5 Times

This step is much easier for most players.

• Use your best PvE setup
• Set your floor reset properly
• Repeat until you get 5 clears at Floor 90 or higher

If your account is already decent, this part is usually straightforward.

↖ 3. Get Astral Bloodline

To get Astral Bloodline, you need Blood Stones.

Blood Stones drop from:

• Enemies in SEA 2
• Sea Beasts in SEA 2

You then use those stones to roll for bloodlines.

↖ Why Astral Bloodline Matters

Astral is not just a mastery requirement. It's one of the better damage bloodlines in the game, so this step gives long-term value beyond Cosmic Being itself.

It also has a passive that boosts sword damage and affects damage reduction for a short window, which makes it even more valuable on stronger builds.

↖ Is Cosmic Being Worth It?

Yes—if you want a melee that feels strong in real gameplay, not just on paper.

From what players are seeing in-game, Cosmic Being stands out because it gives:

• High damage
• Good AoE
• Smooth cooldowns
• Strong farming value
• Better payoff after mastery

A lot of strong weapons hit hard but feel clunky between skills. Cosmic Being is strong partly because the moves flow well, so it performs well in both boss fights and general farming.

That balance is what makes it worth the grind.

↖ Fast Route Summary

If you want the shortest practical version:

1. Go to Punch Island SER 2

2. Talk to the Cosmic Being Trainer NPC

3. Server hop for the Cosmic Being World Boss

4. Farm until you get all required materials

5. Unlock Cosmic Being

6. Complete the 3 mastery quests

7. Unlock the F move and gain the 30% damage boost

If you find the grind slowing down, the fix is usually simple: stop waiting in bad servers.

↖ FAQ

↖ How do you get Cosmic Being in Sailor Piece?

Talk to the Cosmic Being Trainer NPC on Punch Island in SEA 2 and bring the required boss drops, all of which come from the Cosmic Being World Boss.

↖ What is the fastest way to farm Cosmic Being?

Server hopping is the fastest method because the boss spawn timer is the main time gate.

↖ Can the boss drop Cosmic Being directly?

Yes, but the drop chance appears low. It's better to treat it as a bonus, not your main plan.

↖ What are the Cosmic Being mastery quests?

You need to:

• Defeat 15 Cosmic Being World Bosses
• Reach Floor 90+ in Infinity Tower 5 times
• Get Astral Bloodline

↖ Is Astral Bloodline worth farming?

Yes. Even outside this mastery route, Astral gives strong offensive and survivability bonuses, so it is a solid long-term upgrade.

↖ Final Thoughts

Cosmic Being is one of those grinds that looks overwhelming until you realize everything revolves around one boss. Once you build your route around server hopping, the process becomes much more manageable. The melee is strong, the mastery reward is worth it, and Astral Bloodline adds extra value that makes the whole grind feel much better than a simple unlock chase.

For most players, the smartest approach is simple: farm efficiently, avoid dead servers, finish mastery immediately, and treat lucky drops as a bonus rather than a plan.
