[@Rune_Alchemist] Quick tip: Demons count as a heteromorphic race in Overlord  (especially since they have to evolve, normally starting as an imp) rather than demi-human.

[@IceHeart] So... I kind of spotted a small issue with the form of the sheet. The concept of sub-classes is kind of inadequate for the setting, since your classes in YGGDRASIL are independent of each other and level individually, making it possible for an individual to mix main classes in unique ways and stuff like that. I'd say that maintaining the level distribution for races and classes would be more tidy, and we can always fill the unneeded parts with an "Others" like they do in the sheets shown in the novel. 
Also, adding a Karma level would be cool since it effectively changes the player mentality according to the novel.
