- Emotional Metabolization
User can feed of and sustain either themselves or their powers by feeding off the emotions of others. Sometimes this may be done to feed a being higher than the vampire itself. This may sometimes result in death to the victim or may be so subtle it is never noticed.
- May only be able to feed off certain emotions.
- Creatures with this ability may die if they are prevented from feeding for an extended period of time.
- May not be able to feed on suppressed emotions, only surfaced ones.
