And I was just gonna have him able to pull towards himself at first, not even fully lift until he has more practice. I would limit the range to 20 meters but can't use it if the item is closer than 10 meters. As the RP progresses, he'll slowly get stronger with it. As for exhaustion, it tires him out twice as much as if he were pulling with physical strength. Plus, how I planned to make him, most of the deadly stuff he could do is stuff he wouldn't do as it's against his morals.
