"A vampire may also attempt to charm any who gaze into its eyes. The victim must save vs Spells to avoid the charm, with a -2 penalty on the roll. A charmed victim will be totally under the vampire's control, but cannot use spells or magic." (Italicized emphasis mine)
On page B16, the charm spell is limited by:
"Any commands given will usually be obeyed, except that orders against its nature (alignment and habits) may be resisted, and an order to kill itself will be refused."
Is the vampire's charm ability the same as the normal charm spell? If a victim is "totally under the vampires control" can they resist orders against their nature?
