Haki is the combat progression layer that changes dodging, damage, and late-game scaling in Sailor Piece. Observation helps avoid hits, Armament adds damage, and Conqueror's Haki is the gated endgame damage unlock.

Progression role
First defensive unlock
Observation Haki is the dodge layer. It starts with a limited dodge count and scales toward its max, so it is the first Haki to understand before harder bosses punish missed movement.

Haki progression has a natural order
Observation comes first for many players because dodges make harder fights less punishing. Armament is the main damage upgrade and should become a priority once the Snow Island quest is reachable. Conqueror's Haki comes later because it asks for previous Haki levels, Ascension progress, and a fragment.
Leveling turns unlocks into real power
Buying or unlocking Haki is only the start. Observation scales toward more dodges, Armament scales toward a larger damage boost, and Conqueror's Haki adds permanent damage as it levels. Keep the right Haki active during combat so the unlock can grow into its listed max effect.
How to Use This Sailor Piece Haki List
Follow the progression role first, then read the unlock route and requirements. Observation is defensive, Armament is the core damage upgrade, and Conqueror's Haki is the endgame permanent damage layer. Max level and max effect show how far each unlock can scale.
