Why Is Armament Haki Black. In the anime Busoshoku Haki has more visual effects when used at its fullest than just the black skin. My question is if this version is much more powerful than the standard Armament haki why is it nobody used it during the war like why.
Enhancement Haki Stage 5. A heavy concentration or coating of this Haki can be used to harden parts of ones body turning the area black thus making the user denser and more formidable and giving their attacks greater power. The raise in density thus black coloring of a body part is in this haki category called Busoshoku.
It is implied that Hardening is stronger than the invisible application as the characters who are able to use Hardening are.
The aura is what varies ie. Why is that there was no black color of haki before the timeskip. The physical strength attribute of haki works as an invisible armor called Busoshoku Haki. The contrast between the commonality of Armament Haki and the rarity of a black blade there must be more to the process of acquiring a black blade.
