Works but after trail and error it should be more clear.
Your gonna need 2 controllers and 2 profiles.
- Play through "The New Hero" quest up until you're about to pick up the music box (With an Offline/Dummy Profile) -Controller 1
- Save your game at the Music Box (with the dummy profile) -Controller 1
- Join co-op with your MAIN profile (the one to receive the Guild Seals) -Controller 2
- Pick up the music box to get your points -Controller 1/Controller 2
- Don't enter Road to Rule, instead save the game With the MAIN profile and leave the Co-Op game. -Controller 2
- Sign out of your Dummy profile and sign back in (Or if save is located on MU/USB, remove it and Select "Quit to title screen") -Controller 1
This is just to state a more clear way to go about this. If anyone else had trouble.
