Sailor Piece Moon Update Guide – NEW Boss, Codes, Logs

Sailor Piece’s latest update has officially dropped, and this one brings a serious expansion to the game’s progression. From a brand-new power system to a fresh boss fight, new melee weapon, and multiple grind paths, there’s a lot to take in the moment you log in.

If you’re jumping in and feeling overwhelmed, don’t worry—this guide breaks down exactly what the update adds, how everything works, and what you should focus on first to unlock all the new content efficiently.

Sailor Piece Moon Update Guide

This update mainly focuses on increasing your power and giving you more ways to progress.

Here’s the core idea in simple terms:

• You now have a new power system (extra damage buffs)
• There’s a new boss you need to farm
• A new melee (Moon Slayer) tied to grinding
• New items like accessories, title, aura, and clan
• More ways to increase your overall damage and build strength

So basically, this update = more grinding, more power, stronger builds

Step 1: Unlock the New Power System (Lawless Island)

This should be your first priority.

How to unlock it:

1. Go to Lawless Island
2. Find the Power NPC/system
3. Requirements:
   • Level 1150
   • 550,000 Gems
4. Unlock it

How it works:

• You need Power Shards
• These drop from NPCs
• Use shards to roll powers (like Curse Brand)

Why it matters:

• Even basic powers = free damage boost
• This system stacks with everything else
• One of the biggest long-term upgrades

Step 2: Farm Power Shards & Upper Seals

You’ll need to grind NPCs a lot now.

Drops:

• Power Shards → for power system
• Upper Seals → for boss summon

Where to farm:

• Lawless Island NPCs (recommended)

These drops may feel rare, so expect some grind.

Step 3: New Boss (Boss Island)

Next big step is the Moon Slayer Boss

How to spawn:

• Go to Boss Island
• Cost:
  • 750 Gems
  • 1 Upper Seal

Why this boss matters:

• Drops important items
• Likely tied to:
  • New melee
  • Title
  • Accessories

New Title:

• Six-Eyed Demon
• Dropped from this boss

Step 4: Moon Slayer (New Melee)

This is one of the main highlights.

What we know:

• Available in shop preview
• Likely tied to:
  • Boss drops
  • Or future unlock method

Why it matters:

• New melee = potential top-tier weapon
• Worth grinding early

Step 5: Moon Outfit (Accessory)

How to get:

• Drops from NPCs

Why it matters:

• Free stat boost
• Easy to farm while grinding shards/seals

Step 6: New Title, Clan & Aura

Confirmed:

• Six-Eyed Demon (Title) → Boss drop

Also added:

• New Clan
• New Aura

Why you should care:

• Clans = build bonuses
• Aura = cosmetic + sometimes effects
• Titles = progression flex + bonuses
