Sailor Piece Haki Guide
All 3 Haki types — how to unlock & train
Observation Haki

Observation Haki gives you dodge charges to evade lethal attacks. You start with 5 dodges and gain +1 every 10 levels, up to 10 dodges at level 50. It has a 31-second cooldown and earns XP each time you successfully dodge. Activate it with the H key, or enable the Auto Obs Skill setting.
How to unlock
Buy it from the Observation Master on Desert Island for 250,000 Coins + 300 Gems. No questline required.
Armament Haki
Armament Haki is a combat-enhancing haki that coats the user. Its colour is purely cosmetic and is changed with Haki Color Rerolls — 10 standard colours at 9.9% each (Pink, Blue, Red, Green, Purple, Light Blue, Black, White, Brown, Yellow) plus the Legendary Rainbow at 1%.
How to unlock
Complete the Snow Island Haki Trainer's 3-part quest: kill 150 NPCs with Combat, use Combat Z 65 times, punch 750 times with Combat. Then pay 250,000 Coins + 250 Gems.
Conqueror Haki
Conqueror Haki is a powerful area-of-effect attack — the rarest and strongest haki in Sailor Piece, reserved for endgame players.
How to unlock
Prerequisites: Armament Haki level 40, Observation Haki level 25, Ascension 5 and a Conqueror Fragment. Then complete the Conqueror Haki Trainer questline on Shibuya: 500 NPC kills with Armament, 500 dodges with Observation, 200 boss kills and 25 dungeon clears.
