Undeath's Eternal Foe

You grant one or more creatures special abilities that allow them to effectively destroy undead. 

All subjects receive Negative Energy Protection, except that they receive a +10 sacred bonus to saving throws against negative energy attacks. The subjects are also immune to special attacks by undead that involve ability damage, ability drain, disease or poison. Subjects can make melee and ranged attacks against ethereal or incorporeal undead as if they were using Ghost Touch weapons. They also gain a +4 bonus to their AC against attacks from undead.
