Sailor Piece just dropped one of its most content-heavy updates yet, and honestly, this one changes how you grind, farm, and progress. If you logged in and felt overwhelmed by all the new islands, bosses, and currencies—you’re not alone.
This guide breaks everything down in a simple, real-player way: where to go, what to farm, and what’s actually worth your time.
New Islands Overview – Where You Should Go First
The update introduces three new islands, and each one plays a completely different role:
Ninja Island
This is your boss farming zone, mainly tied to Madara (called “Moa” in-game). If you’re aiming for new characters, this is where your grind begins.
Lawless Island
Think of this as your upgrade and crafting hub. This is where you unlock Sid V2, but it’s not straightforward—you’ll need materials and sigils.
Tower Island
This is where things get grindy. It introduces the Infinite Tower mode, which is tied to Acheron (Akiran) and a new currency system.
Madara (Moa) – Boss Spawn, Drops & Farming Route
Madara is one of the highlight additions, and getting him is pretty straightforward—but time-consuming.
How It Works:
- The boss spawns every 5 minutes in the middle of Ninja Island
- You fight and defeat him to get materials/drops
- Then trade those materials with the NPC on the left side of the island
Real Talk:
This is a classic “spawn → kill → repeat” loop. If you’ve got decent DPS, you’ll farm him fast. If not, expect a slower grind.
Tip:
Try server hopping if the spawn timer feels slow—it actually speeds things up a lot.
Sid V2 – Requirements, Sigils & Unlock Method
Sid V2 is where things get a bit more complex compared to Madara.
What You Need:
- Shadow V6 (pre-requirement)
- Multiple materials (visible at the NPC)
- Sigils (important)
Where to Unlock:
- Go to Lawless Island (right side)
- Find the Sid V2 NPC
How to Get Sigils:
- Use the Atomic Boss Summoner
- Sigils are likely dropped from nearby NPC enemies
My Take:
This is not a quick unlock. It’s layered progression:
- Farm enemies
- Get sigils
- Summon bosses
- Collect materials
- Finally unlock Sid V2
If you like structured grinding, this is actually one of the better additions.
Acheron (Akiran) – Infinite Tower Guide & Coins
Acheron is tied to the new Infinite Tower mode, and this is where the update shifts into a more “endgame grind” vibe.
How to Unlock Acheron:
- Go to Tower Island
- Buy her from the Tower Shop
- Cost: 4000 Coins
How to Get Coins:
- Play Infinite Tower mode
- The further you go → the more coins you earn
Important Requirement:
- You need a Tower Key to enter
- No key = no farming
Extra Features:
- You can upgrade your tower to deal more damage
- There’s also an outfit unlock for Acheron
Honest Insight:
This is easily the longest grind in the update. Getting 4000 coins is not quick unless you’re consistently pushing higher floors.
Infinite Tower – What You Should Know Before Grinding
This mode is more than just “stand and fight.”
- It’s about scaling difficulty
- Your build actually matters here
- Tower upgrades can carry weaker players
If you’re underpowered, don’t rush this mode. Farm Madara or Sid V2 first, then come back stronger.
Best Progression Path (What To Do First)
If you’re confused where to start, follow this:
- Farm Madara (Moa) on Ninja Island
- Move to Lawless Island → start collecting sigils
- Unlock Sid V2
- Start preparing for Infinite Tower
- Grind coins → unlock Acheron
This order saves you time and avoids unnecessary struggle.
