Haki is one of the most powerful combat systems in Sailor Piece, the One Piece–inspired Roblox experience. There are multiple Haki types to unlock — including Observation Haki, Armament Haki, and the coveted Conqueror Haki — and each one requires you to find a specific trainer NPC and meet certain obtainment requirements before you can start using it.
Quick answer: To get Haki in Sailor Piece, locate the correct trainer NPC for the type you want, meet the level and quest prerequisites, then complete the trainer's task or pay the required cost to unlock that Haki ability.
Observation Haki and Armament Haki trainer locations
Observation Haki and Armament Haki are the two standard forms most players unlock first. Each has a dedicated trainer NPC positioned in the game world, and you need to reach a minimum level before the NPC will interact with you. Speak to the trainer, fulfill any payment or quest condition they present, and the Haki will be added to your moveset. Once unlocked, you can level up each Haki by using it in combat — the more you rely on it during fights, the stronger it becomes over time.
Armament Haki coats your attacks (and sometimes your character model) in a dark coating, boosting damage output. Observation Haki, meanwhile, grants a dodge or awareness mechanic that lets you avoid incoming hits under certain conditions. Both are essential for progressing into higher-level content where enemies hit harder and have more health.
How to unlock Conqueror Haki in Sailor Piece
Conqueror Haki is the rarest and most difficult variant to obtain. Unlike the other two types, it involves a dedicated quest chain rather than a simple NPC transaction.
Step 1: Make sure you meet the prerequisite before approaching the Conqueror Haki quest. You typically need to have already unlocked the other Haki types and reached a high enough level to trigger the quest dialogue.
Step 2: Locate the Conqueror Haki quest giver. This NPC is separate from the standard Haki trainers and is usually found in a late-game or hidden area of the map.
Step 3: Complete the quest objectives the NPC assigns. These can include defeating specific bosses or clearing combat challenges. Once finished, return to the NPC to receive Conqueror Haki.
You will know the unlock succeeded when the ability appears in your skill or Haki menu. If the quest NPC does not offer dialogue, double-check that you have met all level and progression requirements — missing even one prerequisite will prevent the quest from starting.
Haki colors and how rerolling works
After unlocking Haki, the game assigns your character a Haki color. There are 11 possible colors in total. Ten of them are common variants, each with a 9.9% drop rate, while the eleventh — Rainbow — sits at just 1%. The color is purely cosmetic and does not affect Haki strength or functionality, but Rainbow is a significant flex given its rarity.
If you are unhappy with the color you received, you can reroll it. The reroll process involves interacting with a specific NPC or menu option and spending in-game currency or items. Each reroll gives you a fresh random pull from the same 11-color pool, so landing Rainbow can take many attempts. Because the common colors share nearly equal odds, you are statistically likely to cycle through several of them before seeing the rare option.
| Color type | Count | Drop rate per color |
|---|---|---|
| Common colors | 10 | 9.9% each |
| Rainbow | 1 | 1% |
Tips for leveling Haki efficiently
Simply having Haki equipped is not enough — you need to actively use it for the skill to gain experience and grow stronger. Armament Haki levels up when you land attacks while it is active, and Observation Haki levels up when you successfully dodge or trigger its awareness effect during combat. Fighting enemies close to or above your level tends to yield more Haki experience than farming low-level mobs.
Sailor Piece continues to receive updates that may adjust trainer locations, quest requirements, or Haki mechanics. If an NPC is missing from its expected spot or a quest does not trigger, check the game's official channels for any recent patch changes that might have moved things around.
