It is possible to delevel in Rappelz( rappelz rupees). It is rather painless. If you do feel pain while deleveling, please see a doctor. Deleveling is when you let mobs kill you so you will loose exp, and go down a few levels. People will do this so they don't out level the mobs they are farming. 

This is completely optional. Buying rappelz rupees here! If you don't feel like deleveling search for the next highest mob you can farm and move there. However in Epic 5 deleveling isn't that neccissary since any mob can drop cards. However, we are leaving this section up to anyone who feels like farming Epic 4 style.
