If your damage feels weak in Sailor Piece, your level usually is not the real problem.

The real issue is bad stacking.

A strong build comes from small systems working together: trait, race, clan, Haki, artifacts, runes, relics, blessings, passives, and permanent mode upgrades. Miss two or three of these, and your DPS drops hard.

Here is the clean damage path I would follow on a serious account.

↖ Sailor Piece Best Damage Setup

Start with the basics. These affect everything else.

If you are already in Second Sea, go to World Island and drop down. You can still access the First Sea NPCs there.

↖ Best Trait for Damage

Use Emperor.

Do not overthink this. If your goal is pure damage, Emperor is the trait you reroll for.

↖ Best Race for Sword and Melee

• Use Luckorn if your main damage comes from sword.
• Use Warlord if your main damage comes from melee.
• Do not run a race that does not match your build.

This matters because race bonuses scale with the way you actually fight.

↖ Best Clans for Damage in Sailor Piece

Clans are not cosmetic. They can completely change your DPS.

↖ How to Use Frostbane

Frostbane needs proper setup.

1. Reset stats.

2. Put points into HP and Sword.

3. Do not invest in melee.

4. M1 the boss to build stacks.

5. Swap fast.

6. Use sword, then quickly press F skill.

Speed matters. If you are slow, the combo breaks and the passive loses value.

↖ How to Use Alter Clan

Alter is simple but punishing.

Use 5 abilities, then land your strongest melee skill on the boosted hit.

Do not waste the 1.5x damage on a weak move.

↖ Haki Damage Progression

Unlocking Haki is only half the job. Mastery is where the damage comes from.

↖ Best Haki Upgrade Strategy

Turn on auto skill while farming.

That levels Haki in the background. No extra thinking needed.

If your Haki mastery is low, your damage will stay low even with good gear.

↖ Best Artifact Stats for Damage

Artifacts are one of the biggest hidden DPS checks in Sailor Piece.

Bad artifacts make a good account feel weak.

↖ Artifact Rules That Actually Matter

• Use a full artifact set.
• Farm for legendary pieces.
• Max artifact milestones to improve legendary drop odds.
• Prioritize Damage, Crit Chance, and Crit Damage.

If your build has random artifact stats, fix this before blaming your weapon.

↖ Skill Tree, Boss Rush, Infinite Tower, and Crystal Defense

These modes give permanent power. Skip them and your account falls behind.

↖ Skill Tree Farming

You get 1 SP per 250 kills.

Best farming methods:

• First Sea: use Quake in Shinjuku.
• Second Sea: use Quake or any strong AoE on starter mobs.

SP nodes add up fast. They are boring, but they work.

↖ Boss Rush

Farm Boss Rush once you can clear it consistently.

It is easier than Tower and gives reliable upgrades.

↖ Infinite Tower

Do not rush Tower too early.

Go in when your artifacts, Haki, blessing, and relic are already decent. Tower is harder, but it gives access to the best runes.

↖ Crystal Defense

Clear waves, earn tokens, buy upgrades.

Simple system. Good long-term scaling.

↖ Best Runes for Damage

Runes are a long grind, but they are mandatory for high-end damage.

↖ Rune Level Target

Push your main rune to Level 60.

Expect to need around 700 extra runes to max it.

A low-level Primordial Rune is not the same as a maxed Primordial Rune. Level matters.

↖ Accessories, Enchantments, and Blessings

This is where many players lose free damage.

Go to Shabuya Island for these systems.

↖ Best Accessory

Aim for Asta's Wing.

After you get it, push it to E10. Half-upgraded accessories are wasted potential.

↖ Blessing Priority

Bless your main weapon or spec to B10.

Blessing materials are manageable. Leaving this low is just lost DPS.

↖ Cosmetics, Auras, and Ascension

Cosmetics and auras are not just for looks.

They give damage buffs.

Get crates from:

• Tower shop
• Boss Rush shop
• Crystal Defense shop
• Ascension rewards and codes

For damage, rarity matters most. Get legendary first, min-max later.

↖ Best Power Passives for Damage

Two passives stand out.

↖ Curse Brand

Keep hitting the target until your M1 damage starts climbing.

It gets even better in groups because stacked damage effects speed up boss kills.

↖ Colossus

Use this if you mainly farm bosses.

No setup. Just clean bonus damage.

↖ Second Sea Damage Progression

Second Sea adds the biggest mid-to-late game damage systems.

↖ Best Bloodline

Aim for Demonic Bloodline.

Farm bloodline stones from:

• Second Sea NPCs
• Sea beasts
• Krakens
• Sea serpents

Fastest method: farm sea beasts with a group.

Solo method: farm Second Sea starter mobs with Quake or another AoE skill.

↖ Best Relic to Craft First

Craft the Damage Relic first.

It gives around 30% damage boost. That is too big to delay.

↖ Guild Buffs

Join a guild with damage upgrades unlocked.

A dead guild with no upgrades is dead stats.

↖ Fast Sailor Piece Damage Checklist

Use this order if you want faster results.

If your damage is low, check this list from top to bottom. Do not farm randomly.

↖ Common Damage Problems and Fixes

↖ FAQ

↖ What is the best trait for damage in Sailor Piece?

Emperor is the best damage trait to aim for. It gives the strongest overall damage value and scales well with other upgrades.

↖ What is the best race for sword and melee builds?

Use Luckorn for sword builds. Use Warlord for melee builds. Your race should match your main damage source.

↖ What is the best clan for high damage?

Use Devil Clan for general damage, Frostbane for sword, and Alter Clan for melee burst. Alter gives a 1.5x damage boost after five abilities.

↖ What is the best rune for damage?

Primordial Rune is the best damage rune. It comes from Infinite Tower. If you cannot farm Tower yet, use Havoc Rune from Rune Dungeon.

↖ What should I upgrade first in Second Sea?

Craft the Damage Relic first. It gives around 30% more damage, which is one of the biggest early Second Sea upgrades.

↖ Summary

Your Sailor Piece damage does not jump from one upgrade. It jumps when every system stacks correctly.

Fix these first:

• Emperor Trait
• Luckorn for sword or Warlord for melee
• Devil, Frostbane, or Alter Clan
• Max Haki mastery
• Correct artifact stats and full set
• Asta's Wing with E10
• Weapon or spec at B10
• Damage Relic in Second Sea
• Primordial Rune Level 60
• Boss Rush, Skill Tree, Tower, and Crystal Defense upgrades

If your DPS feels weak, your account is probably not broken. It is under-optimized. Fix the stack, and the damage follows.
