Overview

Haki is a system guide in Sailor Piece.
There are three Haki types in Sailor Piece: Armament, Observation, and Conqueror.

Section

What each Haki does

Haki	Effect	Scaling and cap	How to use
Armament Haki	Adds a direct damage buff to your current build.	Starts at +25% damage, gains +0.5% damage per level, reaches level 100, and totals about +75.5% damage at max.	Press G to toggle it on and off.
Observation Haki	Adds automatic dodges against incoming attacks.	Starts with 5 dodges and gains about 1 extra dodge every 10 levels, reaching 10 dodges at level 50.	Press H to activate the dodge pool.
Conqueror Haki	Adds a passive damage increase and can also release a nearby AoE burst.	Gains +1% damage per level, needs 7,243 kills total to max, and currently caps at level 35.	Press J to trigger the Conqueror blast, or enable automatic use in Settings if your server build supports it.

Section

Section

Haki	How it levels	Per-level result
Armament Haki	Kill NPCs while using it. 1 NPC kill = 1 EXP, with occasional 2x EXP events giving 2 EXP per NPC.	+0.5% damage per level on top of the 25% base bonus, up to level 100 and about +75.5% total damage.
Observation Haki	Dodge attacks while using it. 1 dodged attack = 1 EXP, and 3,250 total dodges are needed to max it.	+1 dodge every 10 levels, growing from 5 dodges to 10 dodges by level 50.
Conqueror Haki	Use Conqueror Haki while killing NPCs with an ability. 1 NPC kill = 1 EXP, and 7,243 kills are needed to max it.	+1% damage per level up to level 35, while also keeping the active J-key AoE blast.

Section

Published model	What it says	What is safe to assume
Shared settled behavior	Conqueror Haki acts as both a passive damage increase and an active J-key AoE blast, and the active blast can also be set to auto-use in Settings on newer builds.	Safe to show. This matches current player testing and the newer activation behavior.
Level-based passive scaling	Current info shows level 35 as the max, with +1% damage per Conqueror level and 7,243 kills needed to max it.	Safe to show as the current scaling model through the tracked max of level 35. Do not list 25% as the cap.
Older passive-only wording	Some older guides reduce Conqueror Haki to a permanent passive damage increase and do not mention the active blast or visible per-level gain.	Useful as older context only, but weaker than current player-tested behavior.

Section

Part	Current note
Applies to	Armament Haki only
Effect	Cosmetic only, with no extra stat gain
Main source	Haki Color Rerolls from bosses, mini-bosses, and some codes
Best known color	Rainbow is usually treated as the chase color because of rarity, not because of stat gain
