Haki/Armament

Armament Haki (武装色の 覇気, Busoshoku Haki) alallows the user to create a force similar to an invisable armor around their body. This allows the user to defend against attacks that would otherwise cause them harm.

Description
Armament Haki allows the user to manifest their willpower into an "armor". This not only allows the user to protect themselves from harm, but allows them to augment their own brute strength. Only significant physical force can overcome this defense, and any attack enhanced by Armament Haki hits immensely harder than it would normally be without it.

This type of Haki also has the ability to bypass the powers of a Devil Fruit user, touching the "substantial body" beneath whatever protection the fruit provides, such as the case of body-altering Devil Fruits such as Logia users. However, unlike seastone, it does not negate a user's Devil Fruit powers, allowing them to defend themselves, and continue fighting normally. By the same effect, this Haki can also be used as a higher level of offensive, more so than just bypassing a foe's Devil Fruit powers.

Techniques
Armament Hardening (武装色 硬化 Busoshoku Kōka): Masters of Armament Haki are able to use it to such a degree it physically makes their body more dense and strong, shown when the body part turns black. When a body, body part, or object is hardened, it becomes black and has a stronger effect than the invisible application of Armament Haki.
