how much damage does conqueror haki do in sailor piece

Conqueror Haki in Sailor Piece gives a permanent damage boost that scales by level, and at the current cap it reaches +35% damage. It does not need to be activated in combat, so the boost is always on.

How it scales

• Each level adds +1% damage.

• Max level is 35 right now.

• Max total bonus is +35% damage.

What that means in play

If your build normally deals 1,000 damage, max Conqueror Haki would push that to about 1,350 damage before other buffs are counted. It is one of the strongest long-term upgrades because it stacks as a passive bonus rather than a temporary skill effect.

Quick note

Some guides still mention older numbers around 25% , but newer sources say the cap was raised to 35% in the March 25, 2026 update.

TL;DR: Conqueror Haki does up to +35% permanent damage in Sailor Piece right now.
