In order to reach the top of the power curve in Sailor Piece, one must eventually farm for the Upper Seal. While this legendary item has always been a gateway to Sky Island upgrades, with the massive Moon Update, which dropped on March 31, 2026, this legendary item has become a key to the most powerful endgame content. This guide includes a look at the fastest farming routes for the new 2026 meta, including new drop locations and what is needed to master the Moon Slayer fighting style. We will also cover the specific requirements you need to meet to get the upper seal. You can visit the Sailor Piece Shop to equip yourself with everything required in this journey.
What is Upper Seal in Sailor Piece?
The Upper Seal is a Legendary-tier material primarily used for high-end crafting and character evolution. In the current meta, it is most famous for being a core component in obtaining the Upper Clan subclass or race evolution, which provides massive buffs to your damage output and stamina regeneration.
Picture the Upper Seal like a tight bundle of sky island energy. Not mere money, but something more solid proof of authority from the toughest leaders up in the Upper Yard zones. Since it's one of those rare finds, you can't pile it endlessly the way you do with old bits of junk or planks. Each piece that lands matters simply because there are so few around.
How to Get Upper Seal in Sailor Piece (Location & Drop Rate)
| Key Metric | Details |
| Location | Skypiea (Sky Island) - Upper Yard |
| Boss Source | Enel (Thunder God) |
| Exact Spawn Point | Near the Golden Bell or the Ark Maxim ship |
| Base Drop Rate | 1% - 3% (Legendary Tier) |
| Boosted Drop Rate | ~5% (With Six-Eyed Demon Title/Luck Accessories) |
| Respawn Timer | 15 - 20 Minutes (Server hopping recommended) |
Head over to the Skypiea map if you're trying to locate the Upper Seal. The spot sits within Upper Yard, a zone players usually reach during mid or later stages of play. Access opens up naturally around those levels.
The Source: Enel (Thunder God)
Floating high above the clouds, you'll find the Upper Seal after taking down the boss known as Enel. This figure, sometimes called the Thunder God, waits at the peak of Upper Yard in the Sky Island. His usual spot sits close to a huge golden bell. Sometimes he stands beside a huge ark shaped like a ship.
- Drop Rate: The base drop rate for the Upper Seal is approximately 1% to 3%.
- Respawn Timer: Enel shows up again, usually between fifteen and twenty minutes after. The wait shifts a bit depending on how long the server has been running and who else is playing. Sometimes it's quicker, sometimes slower, never fixed.
When the drop chance stays that small, chasing a new Enel fight means jumping server to server instead of sitting through the cooldown.
So many people will be confused by adding Enel in the Upper Seal update in Sailor Piece, but it's a smart way to get the Upper Seal quickly.
Why you need to fight with Enel: The Upper seal is the key for the endgame progression, and it is the only way to summon the moon slayer boss at Boss Island and to unlock the powerful moon slayer fighting style. You can reliably farm this seal by defeating Enel at the peak of Upper Yard in Sky Island, where he spawns near the golden bell or the ark Maxim ship. Because the drop rate is a rare 1-3% and the total grind requires 110 seals for full mastery, the most effective strategy is sever hopping to fight Enel repeatedly, which helps you bypass the 15-20 minute respawn timer and fight the boss earlier.
Best Tips to Farm Upper Seal FAST
A 1% drop rate is slow, but the Moon Update makes high efficiency a requirement to hit that 110 Upper Seal goal. Use these four methods to unlock the Moon Slayer style faster:
Master Server Hopping: Do not wait for Enel (Thunder God) to respawn. The second the boss dies, check your loot and hop to a new server. This is the fastest way to stockpile seals for the new Moon Slayer Boss summons.
Stack Luck Buffs: Use the new Six-Eyed Demon title or Luck accessories to push your drop chance toward 5%. This effectively doubles your speed, which is essential for the 85-seal "F" move requirement.
Prioritize High Damage: Both Enel and the Moon Slayer Boss have massive health. To melt their bars, equip Sailor Piece Items that provide percentage-based damage buffs to your fruits. Using a Damage Scroll or Power Band alongside high-DPS fruits like Magma will significantly shorten the fight duration.
Team Up: Join a party to kill bosses faster. You can rotate who spends their seal for the Moon Slayer summon to keep the combat loop going without stopping. Just remember that loot rolls are individual.
How to Use Upper Seal (Materials & Requirements)
Once that legendary yellow glow finally appears in your inventory, you have reached a major turning point. The Upper Seal is no longer just a simple quest item; in the current Moon Update, it acts as the primary "currency" for the game's most powerful endgame content.
To fully master the latest combat style, you will need a total of 110 Upper Seals. Here is a simple breakdown of how to spend them.
1. Summoning the Moon Slayer Boss
Before you can unlock new powers, you have to prove your strength against the Moon Slayer. Unlike other bosses that spawn on a timer, this one must be called manually.
- Where: Go to Boss Island and find the Boss Summoner NPC.
- What you need: 1x Upper Seal, $700,000 Beli, and 700 Gems.
- The Reward: Defeating this boss gives you a chance to drop the rare materials (like Moon Crests and Lunar Essence) needed for the fighting style.
2. Unlocking the Moon Slayer Fighting Style
Once you have collected enough drops from the boss, you can head to the Moon Slayer Merchant on Boss Island to buy the base fighting style.
Materials Needed:
- 25x Upper Seals
- 37,500 Gems
- 1x Moon Crest & 4x Crescent Shards
- 9x Lunar Essence & 16x Demon Remnants
- Required Title: You must have the Six-Eyed Demon title equipped (dropped by the Moon Slayer).
3. Mastering the "F" Move (Ultimate Ability)
The true power of this build is hidden behind the final mastery move. This is the biggest grind in the game and requires you to return to the NPC on top of the upside-down hand at Boss Island.
Materials Needed:
- 85x Upper Seals
- 2x Moon Crests
- 10x Crescent Shards
- Required Clan: You must have the Upper Clan active to unlock this move.
Pro Tip: The Upper Clan Requirement
Don’t start farming the Upper Seal until you've cleared the Upper Clan quest path. The Sky Priest NPC often won’t recognize your progress until you’ve defeated Skypiea guards or found the hidden island tablets. Talking to him first ensures your hard work actually counts toward the evolution.
Also, check your Haki (Aura) level before you commit to the grind. Many evolutions require a specific stage of combat mastery to be active. Without the right Aura tier, the seal will just sit in your inventory as a paperweight until you level up.
Conclusion
Getting the Upper Seal in Sailor Piece is a true test of patience. It marks your jump from a standard player to an elite force. To shorten the grind, focus on Enel and master the art of server-hopping. Keep your Beli and Gems ready, move fast to skip delays, and maintain high damage to shorten battles.
Low drop rates mean empty runs are not failures. They are just part of the process. Stay sharp, team up with others to speed up fights, and verify your active quests before every run. With a steady plan, that legendary power is finally within reach. Only after securing that seal and stepping into the Upper Clan does everything start feeling different. Worth every long session suddenly shows its face.
