In the world of Sailor Piece, the Moon Crest stands out as a highly sought-after resource, vital for those aiming to master one of the most formidable fighting styles in the game. This elusive item is essential for unlocking the powerful Moon Slayer fighting style and its associated F move. However, acquiring the Moon Crest is no small feat; it demands significant effort and perseverance. This guide will walk you through the process of obtaining the Moon Crest and its applications within the game.
How to Obtain the Moon Crest in Sailor Piece
The Moon Crest is primarily acquired by defeating the Moon Slayer boss, which presents a unique challenge due to its extremely low drop rate of just 0.30% when tackled in Normal mode. Unlike common items dropped by regular enemies, getting the Moon Crest requires hunting down a specific boss.
To engage the Moon Slayer, first travel to Boss Island. Here, you need to interact with the Boss Summoner NPC, provide the required materials, and manually summon the boss. It’s important to note that one of the necessary materials for summoning is the Upper Seal.

Once you have successfully summoned the Moon Slayer, unleash your strongest abilities to take it down swiftly. Keep in mind that multiple runs may be necessary, as obtaining the Moon Crest is not guaranteed with each defeat.
Effective Strategies for Farming the Moon Crest
Given the Moon Crest’s low drop rate, efficient farming techniques are crucial. Here are several strategies to enhance your chances of obtaining this valuable item quickly:
- Upgrade Your Build: Enhance your character’s abilities to defeat the Moon Slayer with fewer hits. Consult the Sailor Piece tier list for optimal weapons, devil fruits, and fighting styles.
- Increase Boss Difficulty: Challenging the Moon Slayer at higher difficulty levels can improve the drop rates for the Moon Crest, although it requires additional Upper Seals.
- Utilize Boosts: Equip races, clans, and titles in Sailor Piece that enhance your luck stats. For instance, combining the Alter with Celestial Favor can significantly aid your farming efforts.
- Optimize Your Skill Tree: Invest in luck points within your skill tree and focus on leveling up in the Sailor Piece Ascension to maximize your drop rate boosts.
