Raina hasn't enough power and experience to keep the same level after the dual class reawakening. It's a very complex task, and not everybody can do it. But my technique is special. I'm able to keep the same level after the dual class reawakening. However, you should understand that it's impossible to transfer all knowledge of a dual class. All skills of previous class will be removed. You have to learn the awakening skills of your new class by yourself. Oh, I nearly forgot to mention that the skill enchantment will also be removed!
If you want to reawaken your dual class, bring me 300,000,000 adena.
