Observation, Conqueror & Armament Haki Sailor Piece Guide

Haki is one of the most important power systems in Sailor Piece. If you want stronger damage, better survivability, and long-term scaling, unlocking Haki should be one of your main goals. Right now, there are three types available: Observation, Armament, and Conqueror. Also check out our Sailor Piece Codes for more rewards!

Observation and Armament are much easier to unlock and should be your first priority. After getting both, you can begin working toward Conqueror Haki, since its requirements depend on the other two. Below is a complete breakdown of every Haki type, including perks, level caps, trainer locations, and all requirements.

1. Observation Haki Guide

• Trainer Location: Desert Island
• Level Cap: 50

Perks

• Starts with 5 Dodges
• Gain +1 Dodge every 10 levels (Maximum 10 Dodges)
• Earn 1 XP per successful dodge while Observation is active

Observation Haki mainly improves your survivability. The more you level it, the more dodges you unlock, making it extremely useful in boss fights and PvP.

Requirements

To unlock Observation Haki, talk to the Observation Haki Trainer at Desert Island and prepare:

• 250,000 Money
• 300 Gems

Once unlocked, you level it up by dodging attacks while the ability is active. Since you gain 1 XP per dodge, farming mobs that attack quickly is one of the fastest ways to level it.

2. Armament Haki Guide

• Trainer Location: Snow Island
• Level Cap: 75

Perks

• Base +25% Damage
• Gain +0.5% Damage per level
• Maximum +62.5% Damage at max level
• Earn 1 XP per NPC killed while Armament is active

Armament Haki focuses on damage output. If you want faster farming and stronger boss clears, this Haki is essential.

Requirements

Speak to the Haki Trainer at Snow Island and complete the following:

• 250,000 Money
• 250 Gems
• Kill 250 NPCs using Combat Melee
• Use Combat Melee Z Skill 100 times
• Punch 1,000 times using Combat Melee

After unlocking it, you gain mastery XP by defeating NPCs with Armament activated. The higher the level, the bigger your total damage bonus.

3. Conqueror Haki Guide

• Trainer Location: Shibuya Station
• Level Cap: 25

Perks

• Starts with 1% permanent Damage boost
• Gain +1% Damage per level (Max +25%)
• Deals constant damage to nearby enemies when active
• Earn 1 XP per NPC killed while active

Conqueror Haki is the hardest to unlock but offers strong scaling and passive AoE damage.

Requirements

To obtain Conqueror Haki, you must:

• Have 1 Conqueror Fragment
• Reach Ascension Level 5
• Reach Observation Haki Level 25
• Dodge 500 attacks with Observation active
• Reach Armament Haki Level 40
• Kill 500 NPCs with Armament active
• Defeat 200 Bosses
• Clear 25 Dungeons

This is a long-term grind. The best strategy is to level Observation and Armament first, since many Conqueror requirements overlap with their progression.

Best Order to Unlock Haki

1. Unlock Observation Haki first for survivability.
2. Unlock Armament Haki next for damage scaling.
3. Start working toward Conqueror Haki while leveling both.

By progressing in this order, you naturally complete most Conqueror requirements without extra grinding. Haki in Sailor Piece is not optional if you want to reach endgame strength. Focus on steady mastery farming, activate your Haki during every fight, and you’ll see your damage and survivability improve quickly.
