Outcome manipulation

Outcome manipulation is the ability to change an event or course of events by visualizing the outcome.

Siobhan (Twilight)
Siobhan did not think she had a gift, although Carlisle believed that she could influence events by willing her desired outcome to play-out in reality, but it required her full concentration. Right before the Volturi arrived to terminate the Cullens, she tried to which for a good outcome of the situation, which works out exactly the way she wants, although the vampire Irina is sacrificed in the process. That could be because she was only wishing that the witnesses survived and Irina started on the Volturi side. Afterwards, she finally begins to believe in her gift.

Her gift is depicted as subtle, but very powerful, and is one of those that surpasses Bella's mental shield.
