Sailor Piece damage is not carried by one lucky roll. Big numbers come from stacking permanent systems in the right order.

If your damage feels bad, you are usually missing one of three things: Haki levels, damage multipliers, or gear upgrades. Fix those first. Do not waste all your gems chasing rare rolls while your guaranteed damage systems are still weak.

↖ Best Sailor Piece Damage Upgrade Order

Use this as your checklist. Follow it in order and your damage will scale much faster.

↖ Early Game: Build Guaranteed Damage First

Early game is simple: stop gambling, start stacking guaranteed boosts.

↖ Get Armament Haki on Snow Island

Your first real damage spike is Armament Haki from Snow Island.

Armament Haki starts at around 25% base damage boost and can reach around 75% damage boost when maxed.

That is why we get it early. It scales while you farm, so every mob kill pushes your account forward.

↖ Roll All Stats on Sailor Island

Go to Sailor Island and find the Stat Roll NPC.

If you have 500 gems, use Roll All Stats first.

Look for:

• Damage
• Critical Chance
• Critical Damage

Later, push stats toward SSS and Z-tier. Early on, take any clean upgrade and keep leveling.

↖ Trait Reroll: Do Not Burn Everything Early

Traits matter, but early players waste too many resources here.

Use this rule:

Emperor is one of the strongest traits because it can reach about 2.30x damage.

If you are still weak, do not hard-chase Secret traits. Get stable farming speed first, then reroll later when resources are easier.

↖ Race, Clan, and Artifact Progression

These systems are not flashy, but they add real damage.

↖ Best Beginner Races and Clans

For race, aim for options that boost multiple damage types.

Do not tunnel vision perfect rolls too early. A decent race and clan are enough until your main systems are built.

↖ Unlock Artifacts at Level 500

At level 500, the Artifact System unlocks.

Artifacts drop from mobs. More mob kills mean better long-term artifact progress.

This is why mob farming beats standing around waiting for bosses all day. Mobs level multiple systems at once: Haki, artifacts, drops, skill tree progress, and passive materials.

↖ Boss Damage: Accessories, Titles, and Upgrades

Bosses are worth doing because they drop accessories and titles with real stat boosts.

After getting useful gear, upgrade it at Shibuya Station.

Focus on:

• Damage accessories
• Main weapon upgrades
• High-value boss titles

A weak upgraded item is still weak. Upgrade gear you will actually use.

↖ Runes: One of the Biggest Damage Multipliers

Runes are mandatory for serious damage.

To unlock rune dungeons, collect six pieces:

Then go to Boss Island and defeat 25 Night Bosses.

↖ Best Rune Target

Start with Easy Mode if needed. Move to Extreme Mode once your clear speed is good.

Rune leveling is simple: 1 rune drop = 1 rune EXP. Extreme Mode is best when you can clear it fast.

↖ Level 7,500+: Skill Tree Farming

At level 7,500, unlock the Skill Tree in Slime Island.

You need mob kills for points.

↖ Fast Method: Quake Fruit in Shinjuku Island

Use Quake Fruit at Shinjuku Island.

Position yourself so one skill hits around 10 mobs.

If mobs survive, add more power first. Slow farming kills efficiency.

↖ Level 10,000+: Passive Systems

At level 10,000, unlock Spec Passive in Judgment Island.

↖ Spec Passive Priority

Then work on the Power Passive System in Lawless Island.

Power shards are rare, so take a decent damage passive early and improve it later.

↖ Ascension and Conqueror's Haki

At around level 12,500, push for Ascension.

Why it matters:

• Unlocks stronger code rewards
• Gives access to aura crates
• Gives access to cosmetic crates
• Legendary cosmetics can give around 30% overall damage

After that, work on Conqueror's Haki.

Like Armament Haki, it levels through mob kills and gives another major damage boost. Use the Quake Fruit Shinjuku method to level both Haki systems faster.

↖ Best Mid-to-Late Game Damage Targets

Once your base systems are stable, chase stronger boss and dungeon rewards.

These upgrades are worth farming because they stack with Haki, traits, runes, and passives.

↖ SEA2 Damage Progression

SEA2 is where damage scaling becomes serious.

↖ Farm SEA2 Starter Island First

Use the Quake Fruit method again. SEA2 Starter Island has grouped mobs, which makes it efficient.

Farm for:

• Bloodlines
• Keys
• Artifacts
• Upgrade materials

↖ Best SEA2 Bloodlines

Keep any strong legendary bloodline that improves your damage. Replace it later when you can farm comfortably.

↖ Crystal Defense: Get the Damage Relic

Go to Punch Island and farm Crystal Defense.

Main target: Crystal Damage Relic.

Fast setup:

If the crystal keeps dying, lower the wave count. Fast clears beat failed greedy runs.

↖ Infinite Tower and Secret Runes

Farm Infinite Tower for secret runes.

Best range: floor 30–50.

Secret runes now have pity, so farming is more realistic. Use Ice Queen V move or another strong AoE setup.

↖ Boss Rush Upgrades

Boss Rush gives coins for more upgrades.

Upgrade in this order:

1. Damage

2. Critical Damage

3. Critical Chance

4. Other useful combat stats

Clear speed matters. A fast Medium run is better than a slow Extreme run.

↖ Reaper Race, Guild Buffs, Index, and Mastery

These are endgame damage layers. None should be ignored.

↖ Reaper Race

For raw damage, Reaper is usually the better pick.

↖ Guild Buffs

Join an active guild.

↖ Index and Mastery

The Index gives permanent account stats. Complete it over time.

The Mastery System gives weapon-based scaling. A developed weapon mastery can give around 32.5% damage buff or more depending on progress.

If you constantly switch weapons, your mastery progress slows down. Pick a main damage setup and build around it.

↖ Common Sailor Piece Damage Mistakes

Avoid these if you want fast progress.

↖ FAQ

↖ What is the fastest way to increase damage in Sailor Piece?

Unlock Armament Haki first, then roll stats, get a usable trait, and start upgrading accessories and weapons. Armament Haki alone can reach around 75% damage boost when maxed.

↖ What is the best beginner trait in Sailor Piece?

Any usable Rare or Epic trait is fine early. Do not waste all resources chasing Secret. The best long-term damage target is Emperor, which can give around 2.30x damage.

↖ How do I farm Skill Tree points fast?

Use Quake Fruit in Shinjuku Island. Position correctly so one skill hits around 10 mobs. Since 150 mobs = 1 skill point, this is one of the fastest methods.

↖ What is the best rune for damage?

Havoc Rune is one of the best damage runes. When maxed, it can reach around 1.888x damage multiplier. Later, farm Secret Runes from Infinite Tower for up to around 120% damage buff.

↖ What should I farm first in SEA2?

Farm SEA2 Starter Island first. Use Quake Fruit to clear grouped mobs and aim for bloodlines, keys, artifacts, and materials. Good bloodlines include Primordial, Doombringer, and Ghoul.

↖ Summary

For fast OP damage in Sailor Piece, build in this order:

Armament Haki → Stat Rolls → Trait → Race/Clan → Accessories/Titles → Gear Upgrades → Artifacts → Runes → Skill Tree → Passives → Ascension → Conqueror's Haki → SEA2 Bloodlines/Relics → Guild/Index/Mastery.

The biggest rule: farm guaranteed systems before gambling resources.

Use Quake Fruit for mob-based progression. Use Ice Queen V move for wave content. Upgrade damage, crit damage, and crit chance whenever a system allows it.

Stack enough of these systems and bosses stop feeling like bosses.
