Considering it’s not separate powers, it’s possible. Maybe a higher concentration locally, like a labyrinth can hold more than a big space of the same exterior dimensions?
Lasers take the same energy and bounce it back and forth with mirrors making it stronger and stronger and stronger an when it’s released, it’s a lot “more” than when it started.
So maybe it’s like that. Take a little bit of belief, keep strengthening it, so that when you share it, it’s very powerful.
