Every month under starlight you must sacrifice a person to your patron. this sacrifice empowers both them and you, granting additional spell slots and magically fortifying your physical attributes. should you fail to make this sacrifice your powers will wain, until after 3 months of not sacrificing a person you will die. the sacrificed soul goes to the realm of your patron and cannot be reclaimed, thus any sacrifice cannot be resurrected. no undead can be sacrificed.
