I arrive at the Lawless Island with my fingers tingling and the boss’s roar folding into the wind. The NPC with the sword over their shoulder doesn’t say much—just the cost of admission. You can almost taste the payoff, but you still need the last few pieces.
I will walk you through exactly how you get the Atomic Sword, which runs to prioritize, and the farming shortcuts that save you time. Read this like a raid plan: clear, focused, built around what matters.
How to Get the Atomic Sword in Sailor Piece
On any server the Lawless Island feels like a shop with a guard at the door. Teleport to Lawless Island, go to the island’s right corner, and talk to the NPC holding the blade. That NPC is the gatekeeper: hand over the items below and the Atomic (Cid V2) Sword will be added to your inventory.
- ‘Eminence Incarnate’ Title
- Your own Shadow sword
- 45,000 Gems
- 1x Atomic Omen
- 3x Eminence Essence
- 9x Shadow Remnant
- 16x Magic Shard
- 80x Abyss Sigil
If you prefer the shortcut, the sword is also sold directly in the in-game shop for 1449 Robux (≈ €17).
Sailor Piece Atomic Sword Requirements
Most players notice the required items are clustered around one boss fight. The Atomic (Cid) boss on Lawless Island drops nearly everything you need—Atomic Omen, Eminence Essence, Shadow Remnant, Magic Shard, and even the Eminence Incarnate title. You summon that boss with Abyss Sigils; Normal needs 1, Medium 2, Hard 3, Extreme 4 (one extra per difficulty).
Drop rates from the Atomic (Cid) boss (approximate):
- Atomic Omen: 0.54%
- Eminence Essence: 1.02%
- Atomic Outfit: 1.23%
- Eminence Incarnate Title: (rare drop)
- Shadow Remnant: 4.01%
- Magic Shard: 11.50%
Short version: grind Atomic boss runs on the difficulty you can clear fast. Abyss Sigils come from Arena Fighters (Lawless) or Ninjas (Ninja Island). If you treat each run like a vending machine test, you’ll learn which difficulty pays off most for your build.
How to Get Shadow Sword in Sailor Piece
There’s a small, quiet shop on Dungeon Island that most players miss on their first pass. Go to Dungeon Island and speak to the NPC at the top-left of the building to buy the Shadow (Cid V1) Sword. The NPC requires a set of drops that only the Cid dungeon reliably supplies.
- Shadowborn Race
- 10M Money
- 15K Gems
- 1x Atomic Core
- 4x Shadow Essence
- 8x Void Seed
- 20x Umbral Capsule
Getting that sword is the single most consistent way to meet the Atomic Sword’s “own the Shadow sword” requirement, so don’t skip the dungeon runs.
Atomic Sword Stats and Moveset
Experienced players feel the difference between a good sword and a raid-winning sword in one hit. Atomic (Cid V2) is an endgame AoE weapon built to chew bosses and clear adds. Below are the raw damage figures you’ll see before stat and trait multipliers magnify them.
| Key Bind | Description | Damage Stats |
|---|---|---|
| M1 | Clean slashes and forward strikes at the enemy. | 200,000,000 |
| Z | Launches an upward attack, smashes the ground, then dashes forward with a hard hit. | 300,000,000 |
| X | Creates a cyclone of slashes and then drops down to perform a smash. | 250,000,000 |
| C | Looks very similar to the X move but with massive range: creates a cyclone of slashes, then the blades pause for a split second before launching a smash attack at the ground, embedding it. | 680,000,000 |
| V | A cutscene move that turns the surrounding dark purple, creates a column, and unleashes devastating damage on the ground. | 830,000,000 |
| F | The player levitates in the air, creating a dark purple domain and unleashing devastating AoE damage. | 1,700,000,000 |
Numbers above are baseline. With clan bonuses, race multipliers, and perfect traits your F and V moves will feel like a tidal wave; the sword’s potential scales quickly once you tune a build.
How to Get the Atomic F Move in Sailor Piece
Most players complete a few quests and then suddenly the F move is available. After you possess the Atomic Sword, speak to the Atomic Master NPC on the left edge of Lawless Island to start the Atomic Master quest chain. Finish the required tasks and the F move becomes available for the sword.
- Kill the Atomic (Cid) Boss 20 times on Hard or Extreme: Plan for at least 60 Abyss Sigils total because of difficulty floors.
- Obtain the Eminence Clan: Rerolls come from boss drops, general enemy drops, or occasional Sailor Piece codes.
- Reach Floor 51 on the Infinite Tower five times: Use Tower Island’s Infinite Tower portal and push runs until you hit the quota.
How do I get the F move for the Atomic Sword in Sailor Piece?
Talk to the Atomic Master on Lawless Island and complete the three mastery tasks above: 20 Atomic boss kills on hard/extreme, Eminence clan possession, and five runs to Floor 51. The quest rewards grant the F move for your Atomic Sword.
What do I need to obtain the Atomic Sword in Sailor Piece?
The shopkeeper on Lawless Island asks for the ‘Eminence Incarnate’ title, the Shadow sword, 45,000 Gems, Atomic Omen, Eminence Essences, Shadow Remnants, Magic Shards, and 80 Abyss Sigils. Most items drop from Atomic (Cid); Abyss Sigils and the Shadow sword require separate farming.
If you want a practical route: rotate Atomic boss runs with Arena/Ninja farming for Abyss Sigils. Treat each run like a focused sprint rather than a marathon—hit the objectives that can actually drop the pieces you need. The grind can feel like digging for a needle in a haystack, but a steady loop of targeted runs will pay out faster than random farming.
The Atomic Sword hits like a freight train when paired with Eminence and perfect traits—so your investment in those runs will show up immediately in raid performance. Ready to test your build and claim that blade for your next boss night?
