Getting rare materials is a big part of progression in Sailor Piece, especially if you are aiming to unlock stronger fighting styles. One of the most important materials players are currently farming is the Imperial Seal, a rare drop that many players struggle to obtain.
Because the drop rate is very low and the boss fight requires resources to start, knowing the best farming method can save you a lot of time. This guide explains where the Imperial Seal drops, how to spawn the boss, and the fastest method to farm it. Also check out our Sailor Piece Codes for more rewards!
What Is Imperial Seal in Sailor Piece?
Imperial Seal is one of the rarest materials in Sailor Piece. This item is required to unlock the Chain User fighting style, which many players consider one of the strongest builds in the current meta. The Chain User build is popular because it offers:
- High damage scaling
- Strong area attacks
- Good performance in both PvE and PvP
However, getting the materials needed for this style takes a lot of grinding.
Imperial Seal Drop Location
The Imperial Seal only drops from the Chain User Boss. You can find and spawn this boss on Boss Island. Steps to start farming:
- Go to Boss Island
- Find the Boss Summoner in the main courtyard
- Use the required materials to summon the boss
However, summoning the boss is not free.
Boss Summon Requirements
To spawn the Chain User Boss, you need:
- 3 Boss Keys
- 250,000 Cash
- 400 Gems
Because of these requirements, players usually prepare several keys and resources before starting the grind.
Imperial Seal Drop Rate
The drop rate for Imperial Seal is extremely low.
- Estimated drop rate: around 2%
This means you may need to defeat the boss many times before getting even one seal.
Best Method to Farm Imperial Seal Fast
The fastest farming strategy uses the pity system in Sailor Piece. Here is how it works:
- Defeat 24 world bosses first
- Make the Chain User Boss your 25th boss kill
The pity system guarantees a rare drop on the 25th boss, which increases your chance of getting the Imperial Seal. This method does not guarantee the seal every time, but it significantly improves your chances compared to random farming.
Damage Requirement for Drops
If you are farming in a public server, make sure you deal enough damage to the boss. You must deal at least 10% of the total boss damage to qualify for drops. If you deal less than that, you will not receive any rewards. Because of this, many players prefer:
- Private servers
- Smaller groups
- High damage builds
Items Needed to Unlock Chain User
Getting one Imperial Seal is not enough.
To unlock the Chain User fighting style, you need the following materials:
- 3 Imperial Seals
- 7 Jade Tablets
- 500,000 Cash
- 2,500 Gems
Both the Imperial Seal and Jade Tablets drop from the Chain User Boss, so you will likely repeat the fight many times.
What to Do With Imperial Seals
If you manage to get more seals than you need, do not discard them. Imperial Seals are very valuable and can often be used in player trading for strong items or materials. Because of their rarity, they usually hold high value in the in-game economy.
Once you collect all the required materials, go back to Boss Island and find the Chain User Trainer. Give the trainer the required items and the fighting style will unlock immediately. There are no extra quests required, making the final step simple once you have all materials.
Farming Imperial Seal in Sailor Piece takes patience because of its very low drop rate and the resources required to summon the boss. However, using the pity system and preparing enough boss keys can make the process much faster.
If you plan to unlock the powerful Chain User fighting style, focus on defeating the Chain User Boss repeatedly, manage your resources carefully, and take advantage of luck boosts whenever possible. With enough persistence, you will eventually collect the seals needed for one of the strongest builds in the game.
