How to Get Star Mark in Sailor Piece (June 2026) Guide

If you are playing Sailor Piece and want to unlock one of the most powerful fighting styles in Sea 2, you need to know how to get Star Mark in Sailor Piece. Star Mark is a rare crafting material that you cannot afford to ignore if you are serious about maxing out your character. In this guide, I will walk you through everything you need to know about farming Star Marks efficiently.

What is Star Mark in Sailor Piece?

Star Mark is a rare material in Sailor Piece’s Sea 2 that serves one primary purpose: unlocking the Cosmic Being fighting style. This fighting style, inspired by Cosmic Fear Garou from the anime, provides one of the highest damage boosts available in the game. Without Star Marks, you simply cannot access this powerful combat option.

The Cosmic Being fighting style gives you a massive +95% damage boost when fully unlocked, making it essential for players who want to dominate late-game content. Players tell me this fighting style completely transforms their damage output in both PvP and PvE scenarios.

Star Marks only drop from one source in the entire game. That source is the Cosmic Being boss, which spawns on Punch Island in Sea 2.

Where to Get Star Mark in Sailor Piece?

The Cosmic Being boss on Punch Island is the only enemy that drops Star Marks in Sailor Piece. This World Boss has an enormous 500 billion HP pool, making it one of the toughest challenges in the game. When I first faced this boss, I realized why so many players struggle to farm Star Marks efficiently.

Punch Island is located in Sea 2, and the Cosmic Being spawns at a specific location that resets every 30 minutes server-time. You need to be on Punch Island when the boss spawns to have a chance at getting Star Marks from the fight. Many players use server hopping to catch the boss more frequently.

Cosmic Being Boss Specifications

The Cosmic Being boss has these key statistics that every farmer should know:

First, the boss has 500 billion HP. This massive health pool means you need either a strong group or a very optimized solo build to defeat it before the timer runs out. Second, the boss has a 30-minute respawn timer per server. Third, Star Marks have a base drop rate of 7.61% that can increase with luck modifiers.

The drop rate can reach up to 23% with full luck optimization, which significantly improves your farming efficiency over time.

How to Farm Star Mark: Step-by-Step

Here is the farming method I recommend based on player experiences and my own testing:

Step 1: Server Hop to Punch Island

Join a server and travel to Punch Island in Sea 2. Since the Cosmic Being respawns every 30 minutes per server, server hopping lets you encounter the boss more frequently. Leave your current server and join a new one repeatedly until you spot the Cosmic Being World Boss indicator on the map.

Step 2: Locate the Cosmic Being

Once you arrive on Punch Island, look for the Cosmic Being spawn point. The boss appears at a fixed location on the island. You will see a World Boss notification when it is active. The boss has a distinctive cosmic appearance with purple and blue energy effects.

Step 3: Fight the Boss

Engage the Cosmic Being and deal as much damage as possible before it dies. The boss has 500B HP, so you want to maximize your damage output. I recommend using your highest-damage build and any damage-boosting titles you have equipped. If you die during the fight, respawn quickly and continue dealing damage.

Step 4: Check Your Drops

After defeating the Cosmic Being, check if Star Mark appears in your inventory. Remember that the base drop rate is only 7.61%, so you may need multiple attempts. Keep farming using the server hop method until you collect all 8 Star Marks you need.

Star Mark Drop Rate and Optimization

Understanding the drop rate mechanics is crucial for efficient farming. The base Star Mark drop rate from Cosmic Being is 7.61%. However, this rate can increase significantly with proper luck optimization.

With full luck stacking, the drop rate can reach approximately 23%. This means your chances nearly triple when you optimize your luck modifiers before farming.

How to Increase Your Drop Rate?

Use titles that boost luck. The Dragon Queen title provides a substantial luck bonus and is highly recommended for Star Mark farming. Other luck-boosting titles like Celestial Favor can also help improve your drop chances.

Equip luck accessories whenever possible. Some accessories in Sailor Piece provide passive luck bonuses that apply to all boss drops. Check your inventory for any luck-boosting gear before heading to Punch Island.

Join a clan with luck bonuses. The Eminence clan and similar groups sometimes provide passive luck boosts to members. Being in an active clan with these bonuses can make a measurable difference over many farming sessions.

The Pity System

Sailor Piece includes a pity system for rare drops like Star Marks. While the exact mechanics are not publicly documented, players report that repeated failures to get Star Marks after many attempts increases your chance on subsequent kills. This system ensures that dedicated farmers eventually get their materials.

Cosmic Being Fighting Style Requirements

You need 8 Star Marks total to unlock the Cosmic Being fighting style. Beyond Star Marks, the full fighting style requires several other materials and achievements.

The Cosmic Being fighting style is considered a premium unlock in Sea 2. Players who have unlocked it report significant advantages in both boss fights and player-versus-player combat. The +95% damage boost makes this one of the best investments of your farming time.

Other materials typically required include various boss-specific drops and progression milestones. Check the in-game fighting style menu for the complete list of requirements once you have gathered your Star Marks.

Other Drops from Cosmic Being

The Cosmic Being drops several items besides Star Marks. Galaxy Shards have approximately a 13.14% drop rate and are used in other crafting recipes. Cosmic Essence and Monster Pulse are also possible drops from this boss, though the exact rates vary.

Focus on Star Marks as your primary target, but collect any other rare drops you receive along the way. These materials often have their own uses in crafting or can be traded with other players.

Best Strategies for Farming Star Marks

After analyzing player experiences and testing different methods, here are the most effective strategies for farming Star Marks in Sailor Piece:

Group Farming

Fighting the Cosmic Being with a group is significantly more efficient than solo farming. Multiple players dealing damage means the 500B HP boss dies faster, reducing the risk of timer expiration. Coordinate with other players in your server to form farming parties for the Cosmic Being.

Group farming also means more attempts per hour since you can share boss aggro and revive each other during the fight. Look for active servers with other players farming Sea 2 content.

High-Damage Builds

Use your absolute highest-damage weapons and fruits when fighting Cosmic Being. Check our best weapons tier list for optimal options. The faster you burn through the boss HP, the more runs you can complete per session.

Equip any damage-boosting titles you have unlocked. Titles like Dragon Queen provide both luck and damage bonuses that help with this boss. Review your title loadout before every farming session.

Server Population Impact

Server population affects your farming efficiency in two ways. First, more players means potential competition for the Cosmic Being spawn. Second, servers with active farming communities often have coordinated boss kills that are easier to join.

I recommend trying servers during different times of day to find the best population balance for your schedule. Off-peak hours often have fewer competing farmers but also fewer potential group members.

Time Efficiency

Each Cosmic Being kill takes roughly 5-15 minutes depending on your damage output and group size. With a 7.61% base drop rate, statistical expectation suggests around 13 kills to obtain one Star Mark on average without luck bonuses.

With full luck optimization bringing your rate to approximately 23%, that expectation drops to roughly 4-5 kills per Star Mark. This difference is massive when you need 8 total Star Marks for the fighting style.

Consider using any active active Sailor Piece codes that provide exp or luck boosts before your farming sessions. Even small bonuses compound over hundreds of boss kills.

Frequently Asked Questions

Conclusion

Getting Star Marks in Sailor Piece requires defeating the Cosmic Being boss on Punch Island in Sea 2. The farming process involves server hopping, optimizing your luck modifiers, and repeatedly fighting a 500B HP boss with only a 7.61% base drop rate. While the grind is substantial, the reward is one of the strongest fighting styles in the game.

My recommendation is to always use luck-boosting titles, join group farming sessions when possible, and optimize your damage build before each session. Check the complete boss locations guide for additional farming spots in Sea 2. Also review the Domain Expansion guide for other premium fighting styles you can unlock while farming Star Marks.

With persistence and the right strategy, you will collect all 8 Star Marks needed for the Cosmic Being fighting style. The +95% damage boost makes every farming session worthwhile in the end.
