The Abyss Sigil is one of the most sought-after items in Sailor Piece, and for good reason. You need it to spawn the Atomic Boss and, if you can grind long enough, purchase the Atomic Sword for 80 of them. The drop rate is low, the enemies are endgame-tier, and there is no shortcut. What there is, though, is a smart way to approach the grind.
Where do Abyss Sigils drop in Sailor Piece?
The Abyss Sigil drops from enemies on two specific islands: Ninja Island and Lawless Island. Both locations were added with the massive March 2026 update, so you will need to use a teleport portal to reach either of them.
On Ninja Island, the relevant enemies are level 11,500 Ninjas. They cluster near the NPC that hands out the elimination quest, which is worth grabbing if you still need to level up. On Lawless Island, the targets are level 12,000 Arena Fighters. Both enemy types have a comparable chance to drop the sigil.

How to reach Ninja Island and Lawless Island
Both islands are accessible via teleport portals in Sailor Piece. You cannot walk to them from the main map. Once you arrive, the relevant mobs spawn in fixed locations, so learning the spawn points early saves time.
On Lawless Island, the Arena Fighters respawn at the same spot after being defeated. Sportskeeda's guide recommends staying at that location and waiting for respawns rather than roaming the island. This keeps your kill rate consistent and reduces downtime between drops.
How to increase your Abyss Sigil drop rate
The drop is random, but your Luck stat directly influences how often it triggers. The IGN wiki outlines several methods to raise your Luck:
- Reroll your character's Species to Kitsune, which grants a flat +25% Luck bonus.
- Unlock and equip Runes to stack additional Luck bonuses.
- Level up your Clan for passive stat improvements.
- Equip any of the Boss Kill Titles for a Luck boost.
- Purchase a Luck increase from the Shop.
Beebom adds that maximizing your melee stats matters if you are running a fighting-style build, and that strong accessories and clan bonuses from the tier list can meaningfully speed up the grind. The core takeaway from both sources is the same: Luck is the single most impactful variable you can control.

If you have not rerolled your Species yet, Kitsune is the move before you start farming. The +25% Luck is the largest single Luck gain available without spending real money.
Best farming strategy for Abyss Sigils
After reviewing all three sources, the most efficient approach combines location choice, AoE damage, and Luck stacking.
The IGN wiki specifically calls out Light and Quake Fruit powers as effective for hitting multiple enemies at once, which speeds up the grind even if you are slightly below the recommended level. Sportskeeda echoes the AoE recommendation and adds that upgrading your skill tree for better abilities makes each farming session more efficient.
We suggests unlocking Sailor Piece Ascension to level 4 and redeeming all active codes before you start, since those resources help improve your overall build going into the grind.
warning
Do not spread yourself across both islands on the same session. Pick one, learn the spawn timing, and commit. Splitting your time between locations just increases travel overhead with no drop rate benefit.
What can you do with Abyss Sigils?
Once you have sigils in hand, there are two things to spend them on, both on Lawless Island.
Spawn the Atomic Boss
Find the boss spawner NPC on Lawless Island and hand over Abyss Sigils along with other required materials to summon the Atomic Boss. According to Beebom, the number of sigils required scales with the difficulty level you select for the boss fight. This is the faster use of sigils and opens up access to rewards tied to the Atomic Boss.
Buy the Atomic Sword
The Atomic Sword costs 80 Abyss Sigils and is purchased from the Atomic NPC on Lawless Island. Sportskeeda describes it as dealing serious damage against both regular mobs and bosses, making it one of the stronger late-game weapons. Eighty sigils is a significant commitment given the low drop rate, but for players targeting top-tier gear it is the primary goal.
