How to Unlock Skill Trees & Runes in Sailor Piece (March 2026) Guide

The latest FATE update has revolutionized Sailor Piece with two groundbreaking systems: Skill Trees and Runes. These new features give players unprecedented control over character progression, allowing you to fine-tune your build for maximum damage, survivability, or farming efficiency. Whether you’re looking to push your character past the usual limits or optimize your playstyle, understanding both systems is crucial for dominating the seas.

In this comprehensive guide, I’ll walk you through everything you need to know about unlocking and mastering both Skill Trees and Runes. You’ll learn the exact requirements to access these systems, the most efficient farming strategies, and which runes best suit different playstyles. By the end of this article, you’ll have the knowledge to transform your character into a powerhouse tailored to your specific goals.

Understanding the Skill Tree System

The Skill Tree represents a permanent progression system that allows you to customize your character with lasting stat boosts. Unlike temporary bonuses or gear that can be lost, the Skill Tree provides permanent enhancements that grow with your character over time.

How to Unlock the Skill Tree?

Before you can access the Skill Tree system, you need to meet two specific requirements:

Level Requirement: Reach at least Level 7,500 in the game Cost Requirement: Purchase the system using the required gems from the Skill Tree NPC

Location: The Skill Tree NPC can be found on Slime Island, making it easily accessible once you’ve reached the necessary level threshold.

Once you’ve met these requirements and purchased access, you’ll immediately begin earning Skill Tree points that can be invested in various upgrades to enhance your character’s capabilities.

Skill Tree Points and Farming

Skill Tree points are earned through combat, specifically by defeating enemies. Here’s the exact formula:

• 250 enemies defeated = 1 Skill Tree point
• Points stack over time, allowing you to accumulate them gradually
• Points are permanent and don’t reset when you switch characters or builds

Farming Strategy: The most efficient way to farm Skill Tree points is to focus on areas with dense enemy spawns. Large mob groups in high-spawn zones allow you to defeat multiple enemies quickly with area attacks. This approach not only speeds up kill counts but also provides additional rewards like artifacts and occasional rare crates.

Available Skill Tree Upgrades

The Skill Tree offers five main upgrade categories, each providing different benefits:

Upgrade Type	Base Effect	Max Level Benefit	Best For
Damage	+10% damage	+15% damage	Pure damage builds
Health	+20% HP	+30% HP	Survival builds
Critical Damage	+15% crit damage	+25% crit damage	Critical strike builds
Critical Chance	+5% crit chance	+10% crit chance	Consistent crit builds
Luck	+8% luck	+12% luck	Farming and drop rates

Pro Tip: The Skill Tree system is particularly beneficial if your artifact setup is average, as it can compensate for missing stats and provide consistent growth regardless of your gear quality.

Mastering the Rune System

Runes are powerful modifiers that add special effects and stat bonuses to your character. Unlike the Skill Tree, Runes provide unique effects that can dramatically change your playstyle and combat effectiveness.

How to Obtain Runes?

All runes are obtained through the Rune Dungeon, which you can access using Dungeon Keys. Here’s the complete process:

Dungeon Key Source: Dungeon Keys drop from every World Boss (except Shadow and Chests) Dungeon Access: Use 1 Dungeon Key to spawn the Rune Dungeon Difficulty Levels: Higher difficulties offer better drop chances for rare runes

Recommended Difficulty: For optimal results, run the Rune Dungeon on Extreme difficulty to get the best odds for rare and high-quality runes.

4. Neglecting Level Requirements: Ensure you’re at the right level before attempting difficult content
