Sailor Piece features three powerful Haki types—Armament, Observation, and Conqueror—that boost combat stats, with Rainbow Haki color as the rarest cosmetic upgrade at 1% drop rate.
Armament Haki Location & Requirements
Armament Haki is the first unlockable, focusing on damage buffs.
- Travel to Snow Island and find the Haki Master NPC at the far edge past shops on lower platforms.
- Complete the three-part Combat (melee) questline:
- Kill 150 NPCs using Combat style.
- Use Combat Z skill 65 times.
- Punch 750 times with Combat.
- Purchase for 250k coins + 250 gems.
This Haki activates with G key for melee enhancement.
Observation Haki Location & Unlock
Observation Haki improves dodging and awareness.
- Head to Desert Island beside the Quest NPC to find the Observation Haki Trainer.
- Simply pay 250k coins + 300 gems—no quests needed.
- Activate with H key.
Unlock Armament first, as it’s often a prerequisite.
Players showcase glowing Haki auras like this one during intense Sailor Piece battles, highlighting the visual flair of unlocked powers.
Conqueror Haki Location & Effects
Conqueror Haki delivers AoE stuns and auto-activates on unlock.
- Teleport to Shibuya Station, climb the building with green/red billboards, then the taller one behind it.
- Interact with the Conqueror Haki NPC to buy it (costs similar to others: ~250k coins + gems).
Level all Haki by killing NPCs to max permanent buffs like bonus damage.
How to Get Rainbow Haki Color
Rainbow is a 1% rare cosmetic for Armament Haki (doesn’t affect stats).
| Color Type | Drop Chance | Source |
|---|---|---|
| Common (Red, Blue, Green, Purple, Yellow, Pink, Black, White, Brown) | 9.9% each | Haki Color Reroll |
| Rainbow | 1% | Haki Color Reroll |
Farming Steps:
- Defeat World Bosses (30% drop) or Mini Bosses (3% drop) like Starter Island Bandit.
- Use Haki Color Reroll item to randomly change color—reroll until Rainbow hits (RNG grind).
- Farm low-level bosses early while questing for efficiency.
No auto-reroll; patience required for that eye-catching disco/rainbow effect.
Haki Leveling & Best Builds
- Level Up: Kill NPCs post-unlock; max level grants permanent buffs (e.g., damage amps).
- Tips: Use Combat spec for quests; pair with top-tier fruits from Sailor Piece tier lists.
- Playstyle: Armament for PvP damage, Observation for raids, Conqueror for crowds.
Summary
Unlock Armament on Snow Island (quests + 250k coins/250 gems), Observation on Desert Island (250k/300 gems), and Conqueror at Shibuya Station. Farm Haki Color Rerolls from bosses for 1% Rainbow—grind smart for fast progression in Sailor Piece
