Through firm self-discipline, you have mastered your emotions to Vulcan perfection. No passion-based assault can rattle your judgment, and the base attacks of heart-twisting fiends have little hold on you. Rules-wise, you remain immune to Mind- or Life-based Effects that influence emotions (as detailed in How Do You DO That?, pp. 60 and 120-122), and can shrug off the vampiric Discipline of Presence unless that bloodsucker has at least six dots in that Discipline. Emotion-based powers from werecreatures, faeries, and other such creatures cannot affect you, although you can still be possessed, mind-controlled, enchanted, and otherwise bent or broken so long as the assault is not based on wrangling an emotional response from your perfect serene command.
