So, I have no idea how to rubber band my controller correctly in order to get Raiden in the corner where he's supposed to go, so I just set a keyboard and mouse macro with Razer Synapse. If you have any other macro software, you're free to use it, just copy my inputs as shown here:








Afterwards, just set each to repeat whenever W is clicked and Right Click is clicked.

Following the video below, position the Mistral Body Double behind one of the two pipes in the boss room. If you did it correctly, she will continue walking in a straight line into the wall trying to reach you. At this point, begin your macros and do something else for a couple hours.





Once you come back to the game, you'll see that your combo is incredibly high. The video above is me coming back to the game after a couple hours. If you're satisfied with the amount of BP you've acquired so far, you may continue with the mission and enjoy your spoils. If you'd like to redo the farm for whatever reason, you can reload the checkpoint by going into the customization screen via the codec, like I do in the video.
