 Immortal Arrogance [Monstrous]
Even in undeath, your will is indomitable.
Prerequisite: Iron Will, vampire (non-spawn only)
Benefit: You are immune to the mental control of your master. You can still attempt to feign obedience with a successful Bluff check, and your “master” can still attempt to guess the ruse with an opposed Sense Motive check, as normal.
