"She is overwhelmingly commanding over humans and vampires. Resisting any of her spoken words is very difficult, especially when she is desperate to be in control"
―Entry on Vibeke's gift
People, human and Vampire, are instantly drawn to her command by her suggestions or mere orders, resisting her words are nearly impossible to resist.
It is unknown how to resist her influence over someone, as it based within the mind instead of being physical, it can be blocked by Bella's Shield.
