Atomic Sword (also called Cid V2 or Atomic) is a powerful late-game sword in Sailor Piece, a Roblox game. It stands out for its high damage, massive AoE on skills (especially V and F moves), and strong overall performance in PvE and boss fights.
Sailor Piece Atomic Sword Prerequisites
- Level Requirement: Reach at least Level 12,000 to access Lawless Island via the teleport menu.
- Own the Shadow Sword: This is a mandatory prerequisite (often called the “old” Shadow Sword). You must unlock and equip it before trading for Atomic. Shadow Sword itself comes from earlier progression or specific unlocks on related islands.
- Eminence Incarnate Title: Obtain this title, typically through progression tied to the Eminence clan or related content (some sources mention clan rerolls or specific achievements).
Sailor Piece Atomic Sword Location
Head to Lawless Island (unlocked at high level via teleport portal). Go to the right edge/corner of the island. Look for the Atomic Dealer NPC (often described as holding a sword over their shoulder). Interact with this NPC to see the full trade requirements.
There is also an Atomic Master NPC (usually on the left side of the island) for mastery quests and unlocking additional moves after obtaining the sword.
Complete Requirements to Unlock Atomic Sword
You must provide all of the following to the Atomic Dealer NPC:
- Eminence Incarnate Title
- Shadow Sword (owned/equipped)
- 45,000 Gems
- 1x Atomic Omen (rare drop, ~0.54% chance)
- 3x Eminence Essence (~1.02% chance)
- 9x Shadow Remnant
- 16x Magic Shard (some sources list 15)
- 80x Abyss Sigil
After submitting everything and paying any associated cost, you receive the Atomic Sword.
Note on Drop Rates: Items like Atomic Omen, Eminence Essence, and others are low-percentage drops, primarily from the Atomic Boss (detailed below). Farming requires patience and multiple runs.
How to Farm the Materials (Farming Tips)
The core of the grind revolves around Abyss Sigils and the Atomic Boss:
- Farm Abyss Sigils:
- Defeat strong enemies/NPCs on Lawless Island and Ninja Island.
- These sigils drop consistently from higher-level mobs in these late-game zones.
- You’ll need extras beyond the 80 required, since you use 1–4 sigils per boss summon.
- Summon and Defeat the Atomic Boss:
- Use 1–4 Abyss Sigils at the appropriate summon spot on Lawless Island to spawn the Atomic Boss.
- Fight the boss on Hard or Extreme difficulty for better drops and efficiency.
- The boss drops key materials: Atomic Omen, Eminence Essence, Shadow Remnant, Magic Shards, and possibly other rares.
- It is not a guaranteed drop for every item, so expect multiple kills (players often run it 10–20+ times). Bring a strong build for faster clears.
- Additional Tips:
- Prioritize Abyss Sigil farming first to enable consistent boss summons.
- Combine farming with other late-game activities on Lawless Island for efficiency.
- Gems can be accumulated through regular gameplay, quests, or events.
- Some players recommend auto-farming setups or strong team builds to speed up the process.
- Watch community videos for exact spawn/farm routes (search “Sailor Piece Atomic Sword fast” on YouTube for visual guides).
After Unlocking: Atomic Mastery and F Move
Once you have the Atomic Sword:
- Talk to the Atomic Master NPC on Lawless Island.
- Complete a series of mastery quests to unlock its full skills, including the powerful F Move.
- Example quests (may vary slightly by update):
- Defeat the Atomic Boss 20 times on Hard/Extreme.
- Obtain the Eminence Clan (via clan rerolls).
- Reach Floor 50+ in the Infinite Tower five times.
- Completing these grants access to enhanced abilities with large AoE and high damage.
Uses and Performance
- Combat: Excellent for clearing groups due to massive AoE on V and F skills. Strong single-target damage as well.
- It’s considered one of the top swords in current tier lists for its balance of power and utility.
- Pair it with good races (e.g., Shadowborn if mentioned in some contexts), haki, or other builds for maximum effectiveness.
The grind is heavy and RNG-dependent due to boss drops and sigil farming, so it’s a true end-game commitment. Requirements can shift with updates, so check in-game or recent community sources (Reddit, Discord, or YouTube) for patches.
Happy grinding in Sailor Piece—good luck with those Atomic Boss runs and unlocking Cid V2! If you need tips on specific farms like Abyss Sigils or Shadow Sword first, let me know.
