How to Unlock System Breaker in Universal Piece

Before you can start using System Breaker, you need to collect several key items. Here’s a breakdown of the full process:

1. Find the System Breaker NPC

You’ll find the System Breaker NPC on Solo Island, but before interacting with it, you’ll need the Shadow Heart item.

2. Enter the System Breaker Trial

To earn the Shadow Heart, you must enter the System Breaker Trial. Here’s the checklist:

• Red Soul: Required to access the trial.
• Drop Rate: Shadow Heart has a 45% chance to drop from the trial boss, Sun Jin-Woo.
• Trial Rule: It’s a solo challenge—no teammates allowed.

3. How to Get a Red Soul

To obtain a Red Soul, you’ll need to:

• Open the Red Knight Gate (requires a Chicken).
• Fight Red Knights inside, which have a 2.5% chance to drop the Red Soul.

4. Where to Get the Chicken

To get a Chicken:

• Defeat the King of Curses on Bones Island.
• To summon this boss, use a Ghost Key.
• Ghost Keys are dropped by the System Breaker Boss and Dual Swordmaster Boss.

Pro Tip: You can also fish to randomly get Ghost Keys and Chickens, which is a great shortcut if you’re not into boss farming.

Recommended Farming Order

Here’s a simplified order to farm everything efficiently:

1. Fish or defeat bosses for a Ghost Key.
2. Use the Ghost Key to summon the King of Curses and get a Chicken.
3. Use the Chicken to open the Red Knight Gate.
4. Defeat the Red Knights to get a Red Soul.
5. Use the Red Soul to access the System Breaker Trial.
6. Defeat Sun Jin-Woo to get the Shadow Heart.
7. Return to the System Breaker NPC and unlock your new power.

System Breaker Showcase & Skills

Once unlocked, System Breaker gives you access to powerful shadow-based moves inspired by the Arise system:

Z – Arise Menu

• Allows you to summon or despawn shadows.
• You can collect shadows from bosses you’ve defeated.
• Be mindful: stamina drains faster with more shadows summoned.

X – Egress

• A powerful melee strike with high damage and knockback.

C – Emperor

• A long-range attack that’s useful for mid-range engagements.

V – Biru Summon

• Summons Biru, the Ant King, with a flashy cutscene.
• Deals some damage but is more for style than practicality.

B – Full Arise

• Summons all your collected shadows at once, delivering a devastating multi-hit attack.

The System Breaker in Universal Piece is a high-risk, high-reward path that lets you harness the power of shadows and dominate solo battles. While it requires some grinding, the payoff is worth it—especially if you love stylish combat and powerful summons. Make sure to pace yourself, plan your farming route, and enjoy one of the most unique mechanics in the game. With the right setup, you’ll be clearing bosses and trial challenges like never before. Stay sharp, and happy grinding!
