I couldnt figure out how to put a screenshot of my stand but here it is,
Name; Black day
Power; A
Speed; B
Range; A
Durability; B
Precision; A
Potential; E
Black Day is a stand that covers the users body in shadowy black chains and also allows the user to generate and manipulate said chains, these chains can only be touched by a stand. These chains can also be broken off and still manipulated.
Black Day: Shackles of Death (Black Day Requiem) is no different from Black Day without Requiem, the only difference is that the user of Black Day: Shackles of Death can choose what the chains can touch.
Example:
Youre a stand user wondering the store for bread, you find the bread but no one is near you. Suddenly shadowy black chains faze through the wall of the store and warpping around youre neck, pulling you back and is choking you on the wall. These chains are Black Day: Shackles of death and they currently cant touch the walls but they can touch you meaning youre head is going to be pinched off. The you bring out your stand but more chains faze throught the wall and tie up your stand.
The only way out of the situation above is to have a stand with A or B in power;
Your stand (B or above in power, if you not then youre head gets pinched off :P) burst out of the chains and snaps the chains off around your neck... the rest of the fight is unknown.
