Aversion field

"If someone approaches her ― or Aro, as she is always close beside him in a hostile situation ― they find themselves... diverted. There's a force around her that repels, though it's almost unnoticeable. You simply find yourself going a different direction than you planned, with a confused memory as to why you wanted to go that other way in the first place."

- Eleazar on Renata's power

A protective shield has the power to deflect any and all kinds of physical attack, by making the attacker temporarily forget her or his intentions and motivations and go the other way.

Relatively little is known about this power. Renata, of the Volturi Guard, shows it in protection of Aro, and she needs to be physically in contact with him. On occasion, she includes Marcus and Caius in her shield. Eleazar has mentioned that she can project her shield several meters out from herself to protect those of her priority.

Limitations
This power is more restricted than Bella Swan's. As, like many abilities, it is mental, it does not influence Bella and those she protects.

Also, since her power works by repelling an attacker pursuing her, it probably has no effect against a long-range supernatural talent, such as Jane's illusion of pain or Benjamin's power over the natural elements.

Similar abilities

 * Bella Swan shows the power to shield herself and others from powers that affect the mind, such as mind reading, illusion or any sort of intrusion to the mind. Since Renata's power works on a mental basis, she can probably be rendered powerless by Bella's shield.


 * Afton possesses the power to shield himself from pursuers, making them think that he is invisible. However, his power is much more restrained in that he can only shield himself, and that his power can be easily broken through by someone with a sharp focus.
