How to Get Moon Crest in Sailor Piece (Full Guide + Farming Tips)

Some items in Sailor Piece are optional upgrades. Others are absolutely necessary if you want to reach the late game.

Moon Crest falls into the second category.

This rare material is required to unlock the powerful Moon Slayer fighting style, which is one of the strongest combat styles available in the game. Because of that, players often spend hours farming the boss that drops it.

If you’re planning to unlock Moon Slayer or upgrade its abilities, here’s everything you need to know about getting the Moon Crest efficiently.


How to Obtain Moon Crest in Sailor Piece

The Moon Crest is primarily obtained by defeating the Moon Slayer boss.

Unlike normal enemies that spawn naturally on islands, this boss must be manually summoned. That means you cannot simply explore the map and find it roaming around. Instead, you need to summon it through the boss system.

The drop rate for Moon Crest is extremely low, which is why farming it requires patience.

Moon Crest Drop Rate

The Moon Crest has a drop rate of roughly 0.30% when defeating the Moon Slayer boss on Normal difficulty.

This means you will likely need to fight the boss many times before obtaining one.


How to Spawn the Moon Slayer Boss

Before you can farm Moon Crest, you first need to summon the Moon Slayer boss.

Follow these steps to do it correctly.

Step 1: Go to Boss Island

Use any portal on the map to travel to Boss Island, the location where most summonable bosses appear.


Step 2: Talk to the Boss Summoner NPC

Once you reach the island, look for the Boss Summoner NPC.

Interact with this NPC to open the boss spawn menu.


Step 3: Select Moon Slayer Boss

Scroll through the available bosses and choose Moon Slayer from the list.


Step 4: Submit Required Materials

To summon the boss, you must submit certain materials.

One of the key materials required is the Upper Seal, which acts as the main requirement for spawning the boss.

Once the materials are submitted, the Moon Slayer boss will spawn on the island.


Step 5: Defeat the Boss

Now the only thing left to do is defeat the boss.

Use your strongest build and deal as much damage as possible. Because the drop rate is extremely low, you will likely need to repeat this process many times.

Best Tips to Farm Moon Crest Faster

Because the drop rate is so low, farming efficiently is extremely important.

Here are some proven strategies that can help you get Moon Crest faster.


Upgrade Your Build First

The Moon Slayer boss is not easy to defeat repeatedly with a weak setup.

Before farming, make sure you are using strong equipment such as:

• High damage swords
• Powerful devil fruits
• Strong fighting styles

A powerful build allows you to defeat the boss faster and start the next run quickly.


Increase Boss Difficulty

Another way to improve your chances is to increase the difficulty level of the Moon Slayer boss.

Higher difficulty levels usually provide better rewards and improved drop chances.

However, this method requires more Upper Seals, so make sure you have enough materials before attempting it.


Use Luck Boosts

Luck plays an important role in rare item drops.

To increase your chances of getting Moon Crest, try using builds that boost luck through:

• Titles
• Races
• Clans
• Accessories

Many players combine these bonuses to maximize their farming efficiency.


Upgrade Your Skill Tree and Ascension

Your skill tree luck points and Ascension upgrades can also improve your chances of receiving rare drops.

If you plan to farm Moon Crest regularly, investing points in luck-based upgrades can make a noticeable difference over time.
