She throws one and it will teleport her target without teleporting herself. She can choose to send them away entirely, or she can only teleport parts of her target. She can cut people with the javelins, whatever she cuts could be sent somewhere else. But in Ahmed's Exiles that wasn't what seemed to be happening, it was weirdly ineffective.
She can throw a javelin into a mountain of sand and send it all inside of a person. Or she can hold a javelin in front of herself and block Hyperion's heat vision, redirecting the stream of energy to another target.
