Level 16 Cleric.
You get a new costume at Class level 15. : >
You can buy certain accessories from Town Chests after gaining Fame for finishing quests. For instance, here I've bought [Demon's Left Eye], that randomly boosts my MATK+600 for 8 seconds (5% chance) every time I attack. Of course, it has other useful enhancements (HP/MP, etc.)
Oh, by the way, you can also have a soulmate in this game! Getting one gives you an instant +10%EXP/CEXP buff, and also you'll be able to gain various soulmate skills later. Will cover in the Preview post!
