Haoshoku Haki/Conquerors Haki by definition is:
is a rare form of Haki that cannot be attained through training. Only one in several million people have this ability. This type of Haki allows the user to exert their willpower over others. It is said that whoever possesses this type of Haki has the qualities of a king.
As most have seen watching One Piece this form of Haki has a few displays from small scale to large. What I am asking is if it is indiscriminate. When released on a large scale can it spare individuals? I have seen the cases where single individuals can be targeted by this haki. (i.e. Shanks vs Seaking, Rayleigh vs Elephant) I know that it has been shown people withstanding the haki but that seems to be due more to fortitude of the individual than the user sparing those people. So could a conquerors haki user spare his/her crew if they know they are weak willed?
