That's right. Thief requires a significant amount of dexterity (DEX) and luck (LUK). It's a very attractive job, indeed. Would you like to take the path of a Thief?

Thief. You'll need to head over to Kerning City in order to meet Dark Lord#. Meet him first. In order to become the Thief, you'll have to be at least at Level 10. Make sure to take down the monsters that you may face on your way there.

It'll be quite an experience just to go to where Dark Lord is ... in any case, talk to me when you're ready to choose a path.

Did you make yourself come all the way down to this dingy hideout just to become a Thief?

Haha. See me only when you're ready to become a Thief at heart. I have one rule of thumb about becoming a Thief. Your Level has be to at least at 10.
