How Do I? (Tales Of The Abyss)?

Once you do side quest you will get a title. You can change the titale in the character status screen. Not all titles are costumes keep in mind. My personal Favorites are: Luke-Berserker; win 150 battles on hard difficulty then talk to the guy in the batacle colusieum he is on the pillar. Everyone else looks good in the costumes gotten from Emperor Peony after entering Eldrant once.
