The Ghoul update has two real gates: Blood Flower Quest and Mastery 500. The flower quest unlocks Isolation Island. Mastery gives the damage, luck, crit, and passive buffs that make late-game farming faster. Do the flowers first. Then grind mastery with the right method.

↖ Sailor Piece Blood Flower Quest: Fast Unlock Route

You must accept the quest first.

Go to Starter Island. From teleport, move up to the right-side mountain and talk to the Blood Flower NPC.

If you collect flowers before accepting the quest, you risk wasting the route.

↖ Fastest Blood Flower Order

This route avoids backtracking and keeps every flower tied to a clear landmark.

↖ All Blood Flower Locations in Sailor Piece

↖ Starter Island Blood Flower

After accepting the quest, stay on Starter Island.

From teleport:

• Go left
• Move behind the mountain
• Pick up the first Blood Flower

Do not leave before grabbing this. It is the fastest one.

↖ Bizari Island Blood Flower

Teleport to Bizari Island.

From spawn:

• Go right
• Move behind the mountain
• Collect the flower

Simple spot. Most players miss it by running too deep into the island.

↖ Punch Island Blood Flower

Teleport to Punch Island.

From teleport:

• Go left
• Find the building
• Check behind it

Stay near spawn. The flower is close.

↖ World Island Blood Flower

Teleport to World Island.

Do not search the upper area.

• Go down to the NPC area
• Find Power NPC
• Check behind the NPC

This is a common miss because the flower sits in the lower section.

↖ Slaya Island Blood Flower

Teleport to Slaya Island.

This is the sneaky one.

• Go toward the world boss spawn area
• Turn right
• Find two trees
• Check the second tree

Slow down here. If you sprint through, you will pass it.

↖ Blue Planet Island Blood Flower

Teleport to Blue Planet Island.

Use Spirit Warrior NPC as your marker.

• Go toward Spirit Warrior NPC
• Look for the mountain behind it
• Check behind that mountain

Pick this up and the Blood Flower Quest completes. Isolation Island unlocks.

↖ Blood Flower Quest Checklist

If a flower does not count, check the obvious mistake: you did not accept the quest first.

↖ Sailor Piece Mastery System Explained

Mastery is separate for each weapon or melee.

It is not account-wide. If you max one spec, another spec still starts from zero.

This is a long grind. Use the right farm method or you will burn hours.

↖ Mastery 500 Rewards in Sailor Piece

Mastery is worth doing because the buffs are not cosmetic. They directly improve farming and boss damage.

You start gaining value early. Level 25 already gives useful luck progression, so even partial mastery helps.

↖ Fastest Mastery 500 Method: Starter Island Quake Swap

Best current method: Quake Sea swap farming on Starter Island.

The trick is simple. Quake kills the mobs. Your target weapon gets the mastery credit if you swap fast enough.

↖ How to Do Quake Sea Swap

1. Go to Starter Island.

2. Stand between the two enemy groups.

3. Equip Quake Fruit.

4. Use Sea skill.

5. Instantly switch to the weapon or melee you want to level.

6. Let the kills count.

7. Repeat.

This works on weak specs too. You do not need to suffer through bad damage or slow skills.

↖ Why This Method Is Fast

In testing, normal farming with a strong spec like Dual Wielder gave about 10 mastery levels / 250 kills in 5 minutes. Quake swap is better when the target spec has weak farming.

↖ What Does Not Give Mastery Progress

Do not waste time in the wrong modes.

Mastery progress comes from regular enemy kills. If your mastery bar is not moving, leave that mode.

↖ 2x Mastery Game Pass

There is a 2x Mastery game pass in the shop.

Not required. Worth it if you plan to push several weapons or melees to Mastery 500.

↖ Best Progression Plan After Unlocking Isolation Island

Do not spread your grind too thin.

1. Unlock Isolation Island through Blood Flowers.

2. Choose your main weapon or melee.

3. Start mastery on that spec.

4. Use Quake Sea swap until high mastery.

5. Farm new island content with stronger stats.

This gives the best return. Mastering random specs first slows your real progression.

↖ Common Mistakes to Avoid

Most delays come from routing errors, not difficulty.

↖ FAQ

↖ How do you unlock Isolation Island in Sailor Piece?

Accept the Blood Flower Quest from the NPC on Starter Island, then collect all 6 Blood Flowers. After the final flower, Isolation Island unlocks.

↖ Where is the Blood Flower NPC?

The Blood Flower NPC is on Starter Island. From teleport, go up to the right-side mountain and talk to the NPC before collecting flowers.

↖ What is the fastest Blood Flower route?

Use this order: Starter Island ➔ Bizari Island ➔ Punch Island ➔ World Island ➔ Slaya Island ➔ Blue Planet Island.

↖ What is the fastest way to farm Mastery 500?

Use Starter Island Quake Sea swap. Stand between two enemy groups, use Quake Sea, then instantly switch to the weapon or melee you want to level.

↖ How many kills do you need for Mastery 500?

You need 12,500 kills for one weapon or melee. Each mastery level requires 25 kills, and the max level is 500.

↖ Summary

Unlock Isolation Island first:

Starter ➔ Bizari ➔ Punch ➔ World ➔ Slaya ➔ Blue Planet

Then handle mastery properly:

The clean play is simple: finish the Blood Flower route, unlock Isolation Island, pick one main spec, then grind Mastery 500 with Quake swap. Fast, direct, no wasted movement.
