Haha bud let me tell you something. You are only able to do the RB quest once you have reached lvl 100. When you do the quest it resets your level by 100. So say u do the quest at lvl 100 you will be a lvl 1 again. The catch is that you get to keep all of your skill points and now since you r low lvl again it will be easier to level up. You have to normal train when RB though because gst gives u crap exp. The best time to RB is at lvl 180+ because the cape you gain when u RB has +80 ability points at lvl 180. Also you gain a 10% bonus to the class you have chosen so the higher lvl u were when u RB the more points are gained.

- Hope this helps
