When someone spends a point of Leverage to call out to you, you can choose to roll versus Will to instantly go to them. After rolling, but before results are determined, you can spend any number of Leverage that you have on them to improve your roll (+1 per Leverage). On a critical fail, you have a mishap determined by the GM. On a fail, you don't manage to go anywhere. On a success, you appear at their side. On a critical success, you arrive and then take up to two seconds to assess the situation, and then you can immediately take them back to where you were. Unless you get a critical success, the amount of objects/people you can take with you is limited by your Basic Lift.
If this ability only works if the person speaks your True Name, reduce the cost by 30%.
