Haki is one of Sailor Piece’s core hidden systems, providing permanent boosts to your build and combat potential. Whether you’re aiming to dominate in PvP or crush bosses in PvE, understanding Haki and how to level it efficiently is essential.


How to Unlock Sailor Piece Haki

Armament Haki

To obtain Armament Haki, head to Snow Island and speak with the Haki Trainer NPC. You will need 250k Coins and 250 Gems to start training.

After paying the trainer, complete these three quests:

  1. Haki Trainer 1: Kill 250 NPCs using Combat (fist fighting only).
  2. Haki Trainer 2: Use the Combat Z Skill 100 times.
  3. Haki Trainer 3: Punch 1,000 times using Combat.

What Armament Does:

  • Grants a base +25% DMG boost.
  • Each Haki level adds +0.5% DMG, up to Level 85, for a total DMG increase of 67.5%.
  • Earn 1 EXP per NPC kill, needing 15k EXP to reach max level.

Observation Haki

Speak with the Observation Haki NPC on Desert Island. Unlike Armament, this Haki doesn’t require a questline; simply pay 250k Cash and 300 Gems to learn it.

What Observation Does:

  • Grants 5 Dodges initially, allowing you to completely negate incoming damage and follow up with a combo.
  • Every 10 Haki levels, gain +1 Dodge, maxing at 11 Dodges (Level 60).
  • Gain 1 EXP per Dodge Attack to level it up.

Conqueror’s Haki

Found at the Conqueror Haki Trainer in Shibuya Station, this Haki requires completing a more involved questline after paying 1 Conqueror Fragment.

Quest Requirements:

  • Reach Armament Haki Level 40.
  • Achieve Reacel Level 5 Ascension.
  • Reach Observation Haki Level 25.
  • Kill 500 NPCs with Armament active.
  • Dodge 500 attacks with Observation Haki.
  • Defeat 200 Bosses.
  • Complete 25 Dungeons.

What Conqueror’s Haki Does:

  • Grants a permanent Damage boost, starting at 0% and increasing 1% per level, capped at 35% DMG (Level 35).
  • Gain 1 EXP per NPC kill toward leveling.

Is Haki Worth Obtaining?

Absolutely. Haki is a key permanent enhancement system in Sailor Piece. It complements other growth systems like Titles, Stat Points, Artefacts, Fruits, Swords, Specs, Races, and Accessories.

  • Armament Haki is particularly valuable, offering up to 67.5% DMG when fully trained.
  • Observation provides defensive utility through dodges.
  • Conqueror’s Haki becomes a late-game powerhouse once prerequisites are met.

Q: What are other ways to increase my strength?
A: Titles, Stat Points, Artefacts, Fruits, Swords, Specs, Races, and Accessories all contribute.
