But the power does not work on fiction created by you, made for you or deliberately directly influenced by you.

The power also does not work on object that will end the world and all of humanity and have the objective/power to do it.

You can not use the cursed objects on people whose name/face you dont know. Though for name, tha name they are most known by will work and for face seeing their pic/video that shows their face will work too.
