Now, I've been asked a couple times how Power Scales work, and what each number exactly means. As I've stated in the past, Daes Dae'mar's Power Scale for the One Power is based between 1-150. 150 would be Rand al'Thor, while 1 might be a person that lives and dies and never realizes he or she could've channeled. Power ranks are assigned by only GM's, and you, yourself can not decide your own power, although we'll take suggestions on how your character should be handled.
Below, I've created a scale of Power levels for some of the more popular characters in the Wheel of Time book series. This scale isn't perfect though folks, and I really don't want e-mails from people arguing that "Lanfear is more powerful then Taim", etc. This is how we viewed each character, and this what their power rank would've been if they were characters in DD.
I hope you enjoy.
