How to Unlock Haki in Sailor Piece

There are two types of Haki currently available in Sailor Piece: Armament Haki and Observation Haki. Each one is unlocked in a different location and offers unique benefits for both PvE and PvP.

How to Unlock Armament Haki

To start learning Armament Haki, head to Snow Island and talk to the Haki Trainer NPC. Before you can begin the training, you must pay the required cost.

Armament Haki Requirements

• 250,000 Coins
• 250 Gems

After paying the trainer, you will need to complete three Combat-based quests.

Armament Haki Quest List

Haki Trainer Quest 1

• Defeat 250 NPCs using Combat only

Haki Trainer Quest 2

• Use the Combat Z skill 100 times

Haki Trainer Quest 3

• Perform 1,000 Combat punches

Once all quests are completed, Armament Haki will be unlocked.

What Does Armament Haki Do?

Armament Haki provides a massive damage boost that scales as you level it up.

• Base bonus: +25% damage
• Additional bonus: +0.5% damage per Haki level
• Maximum level: 60
• Total damage bonus at max level: 55%

Each NPC kill grants 1 Haki EXP, and reaching level 60 requires a total of 15,000 EXP. This makes Armament Haki one of the strongest permanent buffs in the game.

How to Unlock Observation Haki

Observation Haki is much simpler to obtain compared to Armament. Travel to Desert Island and speak with the Observation Haki NPC. There are no quests involved—only a payment requirement.

Observation Haki Requirements

• 250,000 Cash
• 300 Gems

After paying, Observation Haki is unlocked immediately.

What Does Observation Haki Do?

Observation Haki focuses on survivability and counterplay.

• Grants 5 Dodges by default
• Dodges allow you to completely avoid incoming damage and follow up with a counter-combo
• Every 10 Haki levels grants +1 additional Dodge
• Dodge cap: 10 Dodges at level 50

Each successful dodge attack gives 1 EXP, making it easy to level during combat-heavy gameplay.

Is Haki Worth Getting in Sailor Piece?

Yes, Haki is absolutely worth investing in. Sailor Piece is not just about weapons and abilities. Haki provides permanent progression that directly improves your build.

Armament Haki is especially valuable due to its massive damage scaling, while Observation Haki gives you powerful defensive tools that can decide fights in both PvE and PvP. If you plan to play long-term, saving your Cash and Gems for Haki should be a top priority.

Haki is one of the strongest systems in Sailor Piece and a key part of becoming truly powerful. Armament Haki offers one of the highest damage boosts available, while Observation Haki gives you reliable survivability through dodges. Unlocking both will significantly improve your performance across all content, making them essential upgrades rather than optional extras.
