ok this is a pretty short guide on how to solo bk's the same configs and method works for most npcs including the bbk
when i first attempted a bk i used power config and shield config, this method was far from affective and i adjusted my configs as i was just taking to much damage. i eventually after a few attempts came up with these configs that mean during the circling you will take absolutely no damage from bk, and you will take down the bk quick enough on death run not to get to dmaged

Once the bk starts to run catch back upto it while still on speed config, as you start firing at it again switch to the config with 150k shields on and finish it off
