Sailor Piece Skill Tree Guide

Among all the game mechanics in Sailor Piece, the skill tree system plays a key role in enhancing a character's power and overall effectiveness. It allows you to improve various hero attributes by spending skill points. However, acquiring these points in Sailor Piece can take quite some time due to certain features.

In this guide, you'll find everything you need: how to unlock the skill tree and earn points, which stats can be upgraded, and other details about this mechanic.

How to Unlock the Skill Tree in Sailor Piece

To unlock the Sailor Piece skill tree, you need to reach level 7000 and have 1000 gems. After that, head to the Slime Island location. There, find the NPC Skill Tree (easily recognizable by the black captain's outfit and the sign above his head).

Sailor Piece Skill Tree

The skill tree is built around five main character attributes:

  • Luck
  • Critical Chance
  • Critical Damage
  • HP
  • Damage

Each of these attributes can be upgraded to five levels. To do this, you must spend skill points sequentially, unlocking each subsequent level.

Damage %

Each level of upgraded damage skill adds +5% to the character's damage, which at the maximum level amounts to +25%.

As the name of the skill branch suggests, this attribute increases the total amount of damage you deal to enemies. It's one of the most important character parameters, so it's worth investing points in it as early as possible.

HP %

For each level of upgraded health branch, the character receives +7.5% HP, resulting in a total increase of +37.5% HP.

Critical Chance

Improving critical chance in Sailor Piece increases the likelihood of landing critical hits regardless of attack type: whether melee, devil fruit abilities, or swords.

How to Earn Skill Points in Sailor Piece

As you might guess, you'll need quite a few skill points to upgrade all character attributes and make them stronger, more resilient, and luckier. However, the logical question arises: how exactly do you earn these skill points?

In fact, it's quite simple: for every 250 enemies defeated, you'll receive 1 skill point. To fully upgrade all branches of the skill tree, you'll need 324 skill points, meaning you'll have to defeat 81,000 enemies.

At first glance, this might seem like an overwhelming number — and it is. However, remember that there are plenty of places in the game where you can easily eliminate large groups of enemies, especially with a level of 7000+ and a good build.

It's best to find a location with a high density of enemy NPCs and use powerful AoE abilities that allow you to eliminate them in one go. You can also try automating farming using Sailor Piece scripts.

It's important not to engage in fights with stronger enemies or those with large health reserves, particularly bosses, as you'll spend a lot of time on them.
