Conquerors grants the user the ability to unleash their own willpower in order to overpower the will of others. This results in victims being mentally overwhelmed by the user, with particularly weak-willed foes instantly losing consciousness. It can also apply pressure onto objects and damage them, a clash between two particularly strong Haoshoku users is capable of "splitting the heavens". Unlike the other types of Haki which can be learned by anyone, Haoshoku is a rare ability that only one in several million people are born with the ability to use.
In One Piece there are three types of Haki; Armament, Observation, and Conquerors.
Armament allows the user to use their own aura as armor to defend against attacks, as well as make their own attacks more potent. It can also be used to bypass Devil Fruit defenses, such as the intangibility of a Logia. A person can apply the armament to a section of their body, over their entire body, and even imbue it onto their weapons. A coating of armament will cause the coated area to turn a shiny black, and a particularly thick and powerful coating will have a flame-like pattern along its edge.
Observation gives the user a sixth sense of the world around them, allowing them to sense the presence, strength, and emotions of other people, even if they are out of sight or far away. It also grants limited precognitive abilities, allowing the user to sense their opponents' intentions and predict their actions and attacks before they happen.
