The Final Boss Glitch still works in Lords of the Fallen whether you're in NG, NG+ or NG++ as it still hasn't been patched by the developers as of April 2, 2016. In order for this to work you must die against the Judge first. While you're still in the building above, cast Level 3 Prayer and immediately leave to the field of battle below. Once you can control Harkyn again, immediately cast Level 3 Prayer again and dodge! Go behind the Judge a ways off and view the theatrics from there wherein he shoots a few spears towards the building and eventually jumps up and disappears. He will reappear behind you but won't attack at all, which gives you the opportunity to finish him off easily.
