Go to Phantom Isle. Talk to Marona and select "Create Character". Then, cycle through them all. If you see the title "Failure" or "Ruined", make that character. It does not matter what level it is. Note: If you do not see any of those titles, close out of that menu and try again. It may take a few minutes to find one. After creating said character with the "Failure" or "Ruined" title, pick him up and talk to Marona. She will ask if you want to banish him from the isle. Answer "Yes". The message "You have acquired the title "Failure/Ruined" will appear. Speak with your DungeonMonk and create a dungeon with enemies ridiculously higher than yours, preferably with few in number. Speak with your Titleist and scroll to the dungeons page. Put the title "Ruined" or "Failure" on the impossibly hard dungeon. The monsters in the dungeon will now be weakened dramatically. You will not get much experience in the battle, but afterwards in the post-battle screen, you will get a large amount of experience points.
