What kind of reward is the Mace of Molag Bal?
do you consider it to be a greater reward than Molag Bal turning someone into a Pure Blood vampire or a Daughter of Cold Harbor or is the Mace an equal gift to that?
I feel its okay if you're already a Vampire Lord but as far as role playing goes and if Skyrim was real, I'd ask to be a Pure Blood instead of accepting the Mace. If the Daedric Lord would allow it.
